CNC Plasma

CNC Plasma 14 Day Maintenance

Test the PH of the water

Locate the PH test strips, in the computer cubby hole at the CNC Plasma Computer station.
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.
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.
Dip the colored end of the strip into the water for about 1 second. Remove and shake excess fluid from the strip.
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
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
Return the pH test strip bottle to the CNC Plasma computer cubby.
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.

CNC Metal Mill (Tormach)

Clean Tormach Coolant System

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.

*Gather Materials*

- 2 Buckets, can be found past the Tormach. One 5 gallon and one smaller bucket that has metal chips in it.
- Rubber gloves (found in custodial room)
- Slotted spoon / spatula (found at the CNC Plasma)

*Clean the Coolant System*

1. Place a 5 gal bucket on the table of the machine.
2. Power the machine on (turn the rotary switch on the right side of the machine to the ON position, and ensure the E-stop on the front of the machine is disengaged). Press Green button to power on.
3. Aim the flexible coolant hose into the bucket, then move the "Coolant" switch to the "ON" position to pump coolant into the bucket.
4. When the pump has run dry, turn the switch back to AUTO when done.
5. Turn off the machine by turning rotary switch on the right back to the origional position.
6. Put on rubber gloves.
7. 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.
8. 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.
9. Refill the coolant tank from the bucket you drained it into in step 3.
10. Top off the tank with fresh coolant, to nearly the top lip of the tank.
11. Return all tools to where you found them.

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)
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.

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

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:
Click on the empty "Tag Name" field. You should see a suggested list of tags.
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.
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:

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.
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.
