It's a 4010 fan, already on max speed when its on
e: but also i will be setting it to trigger on 35C, yea

But overall: I'm going to push my luck later and try pla at 220C because the volumetric flow rate of 69 mm3/s is very nice,
and try something large
but i do think i've solved most of the blocking issues. (not counting stuff like the toolhead parts that need tightening up for better wire managment, better ducts etc etc.)

its so wild that it can do that on it's own
i'm def gonna look into a passive heatsink for it then

I think that would help alleviate the problem, but not fix it entirely. It might be a matter of simply not letting the motor idle when pla is loaded

I think it is fixed with one possible caveat, and I'll sum up the entire fix and the process after I confirm it works but that caveat:
One of the issues was that the heat from the motor was enough to soften PLA. Thus, the heat sink fan was for the motor heat more than the hot end heat creep.
BUT if there exists a situation where the hot end is below 50C and not active, the fan will be off. Thus, there can be a situation where the motor is energized and not cooled. This can cause the PLA to soften enough to misshape and jam on the next print. Such a situation can arise if the sample spread is too large during beacon probing and the print is cancelled.
Active cooling on the motor itself (ie, a second fan) likely wouldn't fix this because it would be keyed into the same state. But I wonder if a passive aluminum heatsink on the motor would help. I do need to redesign the wire support on my toolhead, there's an opportunity to do both at once.
also i would like to note that this just happened as I was typing this lmao

Glad I could help at least!
And later tonight I get to check if it's actually all working now

OH i may have figured it out
I was still getting play when i attached the CHAMP using just the bottom screws, until I switched to screws with larger heads

So the bottom screws do not go through the fan to the champ to the motor

But:
I do not think it is possible to mount the champ with more than the two bottom screws.
It is not possible to mount a 4010 fan to all four holes all the way through
I do not know how to mount the champ in a way that keeps it flush without also using the side holes

These fit tests were all done without a PTFE tube in place to make sure nothing was getting in the way

Error during homing contact on repeated prints
Wanted to give this one last update:
Problem was entirely the angle of the beacon.
- The magnets in the arms had zero impact on the mesh generation.
- The wipe before probe and adaptive mesh have since been re activated with no further issue.
- The distance of the probe may have technically been an issue, but that is a consequence of it being angled
- The end stop position being set incorrectly did lead to issues (in that it was trying to wipe too far away), but that was a misleading symptom to a different problem.
So again, thank you for helping me figure out and correct my own mistake

Is the exact PTFE tube length known? It's kind of guess and check for me
