I will need a quiver control box to accomplish this task as the current dual test stands will not support actuators

@logan check with @west as we had some earlier rev chassis in R&D. They may have different size LCD but should still work.

How are the interface boards being tested?
Should they be tested with the tool head?

I imagine a continuity test would be good
@mjpelletier what are your thoughts

@west We don't have equipment for continuity tests on PCBs to my knowledge.

I think it would be best to assemble the tool head and carriage in pre-sub, and have the tool head assemblers test the whole tool head with the interface board. Only feasible way I see to test these.
This makes it easier to test the tool head too.

This presents a few challenges during final; cant reach screws that mount x carriage to x bearing holder (an adjustment is available for rod spacing) and with the interface board on it is hard to reach for belt routing.
We need a plan for testing interface boards

My current recommendation is not to do a full spit test in pre-sub and keep functional testing limited to the following:
Verify actuator function
Verify heat on both nozzles to 260C
Verify heatsink fans
Verify cooling fan
Visually verify motor function in both directions
Verify probe function

The reason for this is to aide calibration; the auto nozzle calibration utilizes surfaces of the nozzle that aren't as accurately cleaned with the wipe sequence. I feel it would be best to keep the tool heads free of filament until after the auto nozzle calibration is complete so that calibrators don't need to worry about removing filament or cleaning the nozzle thoroughly prior to auto calibration. This would reduce time spent in presub testing as well as reduce wasted material.
@kent what do you think?

The probe function we can verify by extending a lead from the case that the assembler will touch to the nozzle at the end of the test while the gcode utilizes M226 to proceed.

@logan I think it would work let's give it a shot and we can revert to the old way very quickly if any issues arise.

Gathering parts for chassis
Starting on mount today

Stand is built minus an interconnect housing
Working on gcode now

logan reassigned this task from logan to kent.

Complete, ready for review and merge

Thanks @logan. This is merged in now with e4e8160bcf14609057856c334ac42b0881fdf5e4.

We need another one of these made, there is a bottleneck at this test.

Frame is together, parts printing now. I thing have everything else on hand for this so it shouldn't take too long.

yay! thank you sir!

My apologies, it looks like one of the connectors I need is one we don't keep on hand, I have submitted a purchase request for them.

@logan i gave steven the connector and he will bring it to you tomorrow

I delivered a second test stand to AR this morning.
