@erice555 Yep, that is exactly what happened. Remapped it to fan 8 (duex board) and all is well.

I was doing some wiring of my part fan (fan0) and I forgot to turn off the printer. I shorted the two wires together and the board rebooted. Now that I have it all rewired, the fan is on 100% all the time (even when not printing). Does that seem like how it would fail if I damaged my board?
If so, I assume it is possible to use a different fan port and somehow map that to my part fan?

@erice555 I seem to have this working. One can have a motor involved in more than one axis so I just have 4 extra axis a,b,c,d and adjust them as I need. Then I go straight into a print. It still homes Z and all just as it did, so I am golden. Thank you.

Edit: never mind the below. With some searching I figured out a G92 sets the homed state and then allows me to move the 'axis'. So far so good.

@phaedrux I made a good start on this but once I create my 4 independent axis, I don't have a way to home them. How can I fake them out that they are homed so I can move them?

@erice555 If P5 can only be part of one axis then I'll need to completely different config.g files. Will it switch config files without a restart?

@phaedrux Hmmm, seems rather involved but I think I can work it out. Will it let motors P5-P8 participate in more than one axis?
So like P5 can be part of Z and also U?

I have a core xy so there are 4 Z motors that move the gantry in the Z. My inductive probe is not triggering consistenly across the bed so I want to manually level the gantry by just using a piece of paper under the nozzle at each of the 4 corners of the bed. How do I move one Z motor independently of the others?

@gloomyandy Yes, that is what I was thinking of. I was running marlin and SKR 1.3 board. Does reprap have anything like that?

@jay_s_uk oh. I thought I remembered something from my Ender (which I no longer have) that there was a mode where the motors would monitor skipping and adjust/reduce their operating current accordingly. I guess that is a little different that what I said but it is what I was thinking about. Do you know what that is called?

Is there a way I can find out motor temperatures or get a log of motor temperatures over the course of a print?

Solved.
Or rather, not solved but I know what the issue is. I put in a new endstop switch but in doing so found the wiring between the switch and the mainboard is broken on one wire. Somehow since it worked on one wire of the two, it allowed the switch to trigger when it was triggered but according to the mainboard it acted like it was stuck down. So the only time it would act as normal was right after startup when the endstop had not been fired yet.

@erice555 I am going to replace the X endstop and see if this is somehow a switch problem.

So using M119 I can see that X somehow says "at max stop" even after it has moved away from max stop.
Ideas?

Here is my homeall.g:

Voron 2.4 Core XY
Printer was running fine before I had a crash where the print head collided with a warping part and stopped the printer.
Now it won't work correctly.
If I center X and Y axis first, it homes correctly hitting all endstops.
If I try homeall.g again right after that, it will not move on the home X move and ultimately get confused about where the print head is relative to X; which then messes everything up.

What diagnostics do I have available to figure this out or does anyone have any ideas what is wrong?

@jay_s_uk thank you. very helpful.

@jay_s_uk Cool. But how do I set them up so that they 'turn off' after timeout?

When I first turn my printer on, it is quiet. After a print it never returns to the ultra quiet mode. The steppers retain some level of whine. I would like the steppers to return to that quiet phase after timeout. What should I change? Posting my config here.
config.g

I think I figured it out for myself. I added these lines after the z endstop is triggered.

; Z Offset
G1 Y300 ; move back over bed
G1 Z0 ; move to 0
G92 Z.45 ; reset to actual height

I am trying to get my z dialed in enough to print but I am not having any luck.
The Voron 2.4 has a Z endstop switch that is off the edge of the bed and typically above the bed surface (as mine is). It is triggered by the nozzle tip hitting the endstop. My problem is that I am trying to set my offset for the z endstop in homeall.g but I have decided that won't work. Z position after ending homeall.g is always 0. What would be the proper method of setting this up so that z = 0 means the nozzle is at the bed surface, rather than at the position of the endstop? This printer is usually run by Klipper so I can't get help from others who have built/configured this printer.
I tried using baby stepping M290 to do the adjustment but that just ended up with a printer that would not go down to 0 but would stop at whatever height I put into M290.
It seems to me that I would like to run home till I trigger the z endstop, then set the height of Z to be the difference between where it triggers and where my bed surface actually is. I just don't know how to accomplish that.

I am using the below for homeall.g
