# Maintenance - Tech Ready

# 3D Printers



# Recharge 3D printer desiccant pack

## Recharge Desiccant Pack

1. Remove the white rectangular plastic desiccant pack from the "free filament" tote box by the 3D printing cabinet.
2. Inspect the desiccant beads through the front window.
3. Use the legend by the window to gauge if the beads are wet.
4. If the beads are wet, plug the desiccant pack into a wall outlet. \*Set a timer\* and check every two hours. The unit will heat up to drive out the moisture, which will bead up on the inside of the unit before evaporating. Once the condensation is gone and the beads are a happy color again, unplug the unit.
5. Return the dried desiccant pack to the filament box and ensure the lid is closed.

    - Wrap the paper towel around the threaded rod.
    - Clip the Z Axis cleaning device around the paper towel and threaded rod.
    - Move the gantry up and down using the Z Axis Move option in the settings menu.
    - Be careful, the Prusa printers do not stop automatically at the top of travel, so approach the top with caution.
- Apply a dime sized amount of Lithium Grease to a paper towel and wipe up and down the Z Axis threaded rod.
- Move the gantry all the way up and all the way down using the Z Axis Move option (Go to settings in the menu, then move axis, z axis).
- Repeat the last two steps if the grooves of the threaded rod are not covered.
- Wipe off any excess grease.
- Turn off the printer.
- Clean the round linear rails of the X/Y/Z axis with a paper towel and alcohol.
- Apply a small amount of 3 in 1 oil to the rails and move the guides across the oil.
- Wipe any excess oil off.
- Inspect the belts for tension, when picked like a guitar string, they should lightly 'twang'. If they are loose or very tight, file a maintenance report.
- Return cleaning kit to tool tray.

# Purge the scrap bins

### Woodshop

In the woodshop free bin and the free board caddy in the lathe area, remove any wood that:

- Is painted or treated
- Has nails/metal inside
- Is heavily splintered
- Is "swiss-cheesed" with little material to use, etc.

### Metalshop

In the metalshop materials bins in the powdercoating area, transfer any unsuitable metals from the suitable bin to the unsuitable bin. Unsuitable metals includes anything:

- Galvanized/coated
- Swiss-cheesed
- Any materials that aren't identifiable as aluminum or carbon steel

The "unsuitable" bin gets picked up by a service periodically. If it is excessively full, tag @TechLeads in your shift report so we can bug the appropriate people.

### Studio

In the two scrap bins by the laser cutters:

- Remove any small/unusable pieces
- Remove any pieces not on the allowed materials list (see QR code posted on the top of laser 2)
- Break down any pieces with large voids so they fit nicely within the bins

# Verify Tool Tags (Physical & Digital)

Compare Online and Physical Tool States:

1. Open [https://api.protohaven.org/techs](https://api.protohaven.org/techs)
2. Make a note of tools in a yellow or red state.
3. Visit each of the tools listed as red or yellow state and verify that there is a physical tag on the tool that matches that state. If the physical tag is missing, place a fresh one.
4. Scan for tools with physical tags that do not have a digital yellow or red state.
5. Update all tool reports to match the current state of the tool - this may not necessarily be exactly what the tag says. If you're unsure, ask on #maintenance.

# CNC Metal Mill (Tormach)



# Clean Tormach Coolant System

<span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">The coolant system on the tormach has a tank and a filter screen on it - these should be inspected and cleaned regularly so the coolant can properly flow.</span>

# Gather Materials

- <span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">2 Buckets, can be found past the Tormach:</span>
    - <span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">One 5 gallon bucket</span>
    - <span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">One smaller bucket that has metal chips in it</span>
- <span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">Rubber gloves (found in custodial room)</span>
- <span data-sheets-root="1" style="font-size: 10pt; font-family: Arial; font-style: normal;">Slotted spoon / spatula (found at the CNC Plasma)</span>

# Clean the Coolant System

1. Place a 5 gal bucket on the table of the machine.
2. Power the machine on: 
    1. Turn the rotary switch on the right side of the machine to the ON position.
    2. Ensure the E-stop on the front of the machine is disengaged.
    3. Press Green button to power on.
3. Place the 5 gal bucket under the coolant sprayer.   
    *Turning on Mach3 and moving the table to one side may be necessary.*
4. Run the pump.
5. When the pump has run dry, turn the switch back to AUTO when done.
6. When done using the computer, close Mach3, and go to the start menu on Windows and select shut down. Wait for the computer to fully shut down.
7. Turn off the machine by turning rotary switch on the right back to the origional position.
8. Put on rubber gloves.
9. Scooping from the right side (near the pump) to the left to avoid packing chips into the filter screen, use the slotted spoon/spatula to scoop the chips from the bottom of the coolant tank into a maintenance bucket.   
    *Get as many chips out of the coolant tank as reasonable; it does not need to be perfectly clean.*
10. Place the chips in the aluminum recycling trash can that is in the machine shop area.   
    *Some contamination of metals is unavoidable, but try to avoid introducing too much coolant into the recycling can.*
11. Refill the coolant tank from the bucket you drained it into in step 3.
12. Top off the tank with fresh coolant, to nearly the top lip of the tank.
13. Return all tools to where you found them.

# CNC Plasma



# CNC Plasma 14 Day Maintenance

Test the PH of the water

1. Locate the PH test strips, in the computer cubby hole at the CNC Plasma Computer station.
2. Use a stick or other object to lightly stir the water in the table. Just lightly move the water in between the slats, careful not to splash out. Stir at least half the table.
3. Remove one PH test strip from the bottle, seal the bottle back up quickly and make sure the lid is snug, the strips will go bad when exposed to air.   
      
    **NOTE:** Prior to wetting the strip, read steps 4 through 6 before continuing. The pH strip reading is most accurate immediately after the strip is wetted, and the indicated pH will continue to change after wetting.
4. Dip the colored end of the strip into the water for about 1 second. Remove and shake excess fluid from the strip.
5. Compare the strip to the color chart on the bottle as follows: 
    - Hold the bottle in your left hand up right
    - Hold the test strip in your right hand by the portion that is not exposed to the liquid
    - Match the colors on the test strip parallel to one of the 14 rows corresponding to the pH on the bottle
6. Take note of the PH reading: 
    - If the reading closely matches two rows on the bottle, record the pH to the 0.5 increment between the two rows
    - Example: The test strip shows between 9 and 10. The pH is recorded as 9.5

# Drum Sander



# Monthly Maintenance

- Perform [weekly maintenance](https://wiki.protohaven.org/books/maintenance-tech-ready/page/weekly-maintenance-kFd "Weekly Maintenance")
- Remove the lower panel on the infeed side of the machine. Vacuum dust buildup from inside cabinet and off motor.
- Check v-belts for damage, tension, and wear. Yellow/Red tag the machine if issues are observed.
- Check for problematic issues: 
    - Loose mounting bolts.
    - Worn or damaged sandpaper.
    - Worn switch or buttons.
- Lubricate pillow bearings (fig 2) with 1–2 pumps from a grease gun. 
    - The manual says this should be done weekly, or per 20 hours of use. I expect monthly should be sufficient based on our usage.
    - Avoid adding too much grease, which attracts sawdust.
- Yellow/Red tag the machine if issues are observed.

# Weekly Maintenance

- Lubricate conveyor roller bushings with a couple drops of 3-in-1 oil from a can (located in Maintenance Cart drawer) in holes(fig 1). 
    - The manual says this should be done daily—since we do not see daily use, weekly should be OK
    - Avoid adding too much oil, which attracts sawdust
- Vacuum dust buildup from underneath top cover.
- Check for worn or damaged sandpaper. Make a tool report that yellow tags the sander and alert the maintenance crew if the sandpaper needs to be cleaned.
- Check to see if the belt is tracking properly. The conveyor belt should not be touching the silver metal shields on each side. Make a tool report that yellow tags the sander and alert the maintenance crew if the conveyor belt tracking needs to be adjusted.

# Maintenance Task Automation - For New Tasks, Start Here!

#### Maintenance Automation

The pages in this book (as well as the ones in Maintenance - Training Required and Maintenance - Admin Required) are used by software automation to periodically schedule tasks in the [Shop &amp; Maintenance Tasks](https://app.asana.com/1/1199692158232291/project/1202469740885594/task/1210501384806873) Asana project.

<p class="callout warning">Scheduling automation will only operate on pages that have been approved and which have the appropriate tags (as below).</p>

#### Applying maintenance tags to a page

1. While editing a wiki page, look to the right side of the page for an icon panel. There should be a "Page Tags" button there, that looks like a luggage tag:  
    [![image.png](https://wiki.protohaven.org/uploads/images/gallery/2025-06/scaled-1680-/Dzximage.png)](https://wiki.protohaven.org/uploads/images/gallery/2025-06/Dzximage.png)
2. Click on the empty "Tag Name" field. You should see a suggested list of tags.
3. Click on one of the suggested tags prefixed with `maint_` to add it to the tags list. Repeat for all other tags with that prefix, so you have `maint_level`, `maint_freq_days`, etc. all listed with their tag values not yet set.
4. Fill in the tags, using the suggested tag values to help. It may also help to use an already tagged wiki page as a reference by observing the set tags on on the left side of the page:   
    [![image.png](https://wiki.protohaven.org/uploads/images/gallery/2025-06/scaled-1680-/NuAimage.png)](https://wiki.protohaven.org/uploads/images/gallery/2025-06/NuAimage.png)  
    <p class="callout info">To set the tool\_code tag, go to [https://www.protohaven.org/equipment/](https://www.protohaven.org/equipment/) and scroll the Index table so the "Tool Code" column can be seen on the far right. Use the code for the corresponding tool.  
    </p>
    
    <p class="callout info"> The `maint_ref` field can be anything, but it must be different than all other tasks. You can just grab a [randomly generated UUID](https://www.uuidgenerator.net/), name it similar to the maint\_task value, etc.</p>
5. Save the page when you're done. You can verify the page is visible to automation by clicking [this link](https://wiki.protohaven.org/maintenance_data/maintenance-tech-ready?approval_threshold=1) and using Ctrl+F to search for your task by name (note: works for tech\_ready maintenance only)

#### Maintenance Tags

For details on what each tag means, see [https://wiki.protohaven.org/books/metabook/page/tags-for-wiki-task-pages](https://wiki.protohaven.org/books/metabook/page/tags-for-wiki-task-pages)

#### Approving maintenance pages

Scheduling automation will not schedule maintenance on a page which has not been approved by at least one person with approval ability. See the header on [this page](https://wiki.protohaven.org/approvals) for details on how to mark approvals, and who has this ability.

# Inspect and rotate sandblaster nozzle

Service manual - [https://drive.google.com/file/d/10XyBZ8bd7pk9Vfl4iO3T76M2VwWSfi9C/view](https://drive.google.com/file/d/10XyBZ8bd7pk9Vfl4iO3T76M2VwWSfi9C/view)

## Safety

- Wear a dust mask.
- Wear safety glasses.

## Inspect/Rotate Nozzle

1. Unplug the sandblaster
2. Find a 1/8" Allen key in the maintenance cart.
3. Unlock the carbide nozzle at the front end of the spray gun using the allen key, so that it can be removed.
4. Take note of the nozzle position, in the end, we will want to reinstall the nozzle 1/4 turn further.
5. Remove the nozzle and inspect for wear on the part that is inside the gun. If the wear is getting bad, let maintenance know.
6. Rotate the carbide nozzle 1/4 turn clockwise (as looking down the barrel - but don't actually look down the barrel).
7. Lock the carbide nozzle in place using the Allen key.

## Inspect the Spray Gun and Tube

Inspect all around the body of the spray gun and the tube below it for holes. The steel tube can wear through on the back side of the 45º bend, on the part that faces the cabinet.

If any holes are found, red tag the sandblaster and file a maintenance report.

## Check the Media Level

A small amount of media is better than overfilled. There only needs to be about 6" of media in the bottom the cabinet. If it looks low or over filled, contact the area lead for the Sand Blaster.

## Notes

Rotating the nozzle extends the life of the nozzle.

# Sandblaster - Deep clean

## Safety

- Wear a dust mask. (If you do not have your own, disposable masks are available in the custodial room.)
- Wear safety glasses.

<span style="color: rgb(34, 34, 34); font-family: Nunito, sans-serif; font-size: 2.8275em; font-weight: 400;">Tools/Materials Required</span>

- Two 2-gal buckets (should be located near the machine)
- Soft mallet.

## Clean Siphon Tube

1. Remove the siphon tube via the two screws at the top. (Be careful and avoid dropping the screws.)
2. Inspect the siphon tube for holes and file a tool report if any are visible.
3. Blow compressed air through the siphon tube to dislodge any caked on abrasive and dirt.
4. Reinstall siphon tube.

## Clean Media

1. Place a bucket under the bottom gate of the cabinet.
2. Open the gate to drain out the media.
3. Tap the sides of the hopper with a soft mallet to get any remnants out. (We don't need the hopper completely clean.)
4. Take the buckets and a sifter outside.
5. Pass the material through the sifter to remove and debris.
6. Discard debris in the dumpster.
7. Dump the sifted media back in the cabinet.

## Test Hopper Motor

1. Turn on the machine.
2. Verify hopper motor under the cabinet is active and vibrating. If it isn't running, file a tool report.

# Slip Roll, Sheet Metal



# Oil slip roll rollers

##### Safety:

Ensure the machine is turned off and unplugged before oiling the rollers.

##### Oil the rollers

Apply several drops of 3-in-1 oil (located in the maintenance cart) to the three large rollers of the slip roll. Most of the oil ports will be small holes towards the ends of either sides of the rollers - they'll be on parts of the roller that do not actively rotate when the machine is in operation:

- One oil port located on the left side of the top drive roller, plus the movable bushing on the right hand side (the one that you pull out to allow removal of fully concentric projects, see picture below)  
    [![image.png](https://wiki.protohaven.org/uploads/images/gallery/2025-06/scaled-1680-/image.png)](https://wiki.protohaven.org/uploads/images/gallery/2025-06/image.png)
- Two oil ports on either side of the bottom drive roller - you can lift the top roller out via the removable bushing on the right side.
- Two oil ports on either side of the idler roller on the back of the machine

##### In case of excessive friction

If the rollers aren't rolling freely after applying the 3-in-1 oil, use a spray can of WD-40 on the oil ports and work the rollers back and forth (side-to-side as well as rotating around) to dislodge any gunk.

# Facilities & Outside



# Magnet roller the parking lot

Sharp metal debris can accumulate in our parking lot - this poses a hazard to car tires, so it's important to periodically pick up metallic sharp objects using our magnet roller.

1. Retrieve the magnet roller, usually located near the recycling bin by the forge area or alternatively behind the metal lathe (near the spare gas tanks)
2. Walk the roller all throughout the parking lot as if you were vacuuming a floor. 
    1. Periodically bring the roller to a non-parking area and pull the black handle on the roller up do disengage the magnet and drop off any debris.
3. When finished, shop vac up any recovered debris and store the roller back where you found it.

\*There is no obvious low battery indicator, we are doing this on a 9 month cadence to be safe\*

# Welding Tables



# Welding Table Maintenance

### Welding Table Maintenance (Mig and Tig tables)

Wipe table down with a dry rag.

Inspect the table for spatter/BBs. Use a straight edge to assist in finding them. If tables have not seen much use, looks to be free from BBs and still has a good coating of anti spatter, just mark this task complete.   
  
Use a cold chisel (solid bar with a wedge on the end, not a woodworking chisel!) and hammer to remove them by placing the chisel as close to parallel to the surface of the table as possible and striking with moderate force. Chisels and punches should be in the top of the welding tool box (or in the forge, return to the forge when done using).

If the spatter does not come off with one tap of the hammer. Circle with a sharpie and note it in a maintenance report, check the asana task box to generate an asana task with it. DO NOT GRIND THE TABLE.

Use a round punch to remove spatter from dog holes. If they do not easily pop off, also circle and include in the maintenance report.

Finish by lightly coating the tables with anti spatter spray.

# Pantograph



# Oil the Pantograph

The pantograph needs occasional oiling. We use the way oil from the manual metal lathe that is in the black bottle on the lathe. 2 pumps of oil in each spot of the pantograph is sufficient.

[![IMG_0814.jpeg](https://wiki.protohaven.org/uploads/images/gallery/2026-03/scaled-1680-/img-0814.jpeg)](https://wiki.protohaven.org/uploads/images/gallery/2026-03/img-0814.jpeg)

There are many places to oil the machine, there are ball oilers, where the nozzle of the oil can needs to be pushed into the ball oiler and a couple pumps are dispensed. There are also dovetails that need a little oil. Just dripping a little oil on the dovetails and spreading around is usually sufficient. Make sure to get both sides (or top and bottom of each dovetail that is listed in the images.

Dovetail below the Deckel sign, Dovetail to the right of it. 3 ball oilers (one on each handle). One ball oiler in the center of the casting.

# Injection Molder



# Injection molder - lubricate clamp system

1. Ensure there are no obstructions inside the chamber - should just be a couple aluminum blocks.
2. Identify the "PUSH TO CLAMP" knob on the bottom left of the machine, and the locking lever underneath it
3. Slide the lock lever to the right, then push the knob in to initiate clamping. Make a note of any jittering/seizing in the clamp mechanism.
4. Pull the knob out to return the clamp to the rest position.

If there was jittering/seizing when clamping, apply a light amount of spindle to the three ports - one at the base of the middle bar, and one on either side of the drum towards the rear of the clamping assembly. Then repeat steps 1-4 several times to work the oil into the system.
