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.

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

  7. Return the pH test strip bottle to the CNC Plasma computer cubby.

  8. Make an Air Table (Not ASANA) tool report:

    • In the "What would you like to Report" Section, enter "CNC Plasma 14 Day Maintenance entry: pH=[the measured pH]" 

    • If the PH reading is NOT between 9 and 10:
      • Check "Create an Asana Task?" task to adjust the PH level of the table.
      • Indicate in the "What would you like to Report" section "pH adjustment is required" in addition to the pH measurement entry above.

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 & Maintenance Tasks Asana project. 

Scheduling automation will only operate on pages that have been approved and which have the appropriate tags (as below).

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
  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

    To set the tool_code tag, go to 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.

     The maint_ref field can be anything, but it must be different than all other tasks. You can just grab a randomly generated UUID, name it similar to the maint_task value, etc.

  5. Save the page when you're done. You can verify the page is visible to automation by clicking this link 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 

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 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

Safety

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.

Slip Roll, Sheet Metal

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:

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.

Replacement Throat Plates for the Router Table

We have a Woodpeckers model number mumble router table attachment, which accepts plastic throat plates for supporting workpieces against various sized bits. The throat plates have proven to be somewhat sacrificial (particularly the popular sizes). We can print more of them:

We have files for the following apertures:

Aperture Size STL FIle
0.5 Inch WoodpeckerThroat1_2.stl
0.75 Inch WoodpeckerThroat3_4.stl
1 Inch WoodpeckerThroat1.stl
1.25 Inch WoodpeckerThroat1_1_4.stl
1.5 Inch WoodpeckerThroat1_1_2.stl
1.75 Inch WoodpeckerThroat1_3_4.stl
2 Inch WoodpeckerThroat2.stl

PLA is not recommended for this application: the insert will be brittle, and may shatter.

3D Printable Shims for under the router plate

These Shims are used to keep the Rockler router plate level with the table.  The shims are tapered from .045" in the rear to .018" in the front.  Two are needed, one for each side of the router plate, and are placed between the aluminum plate and the fiberboard table.

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.

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.

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 - 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.
