CR10 S5 upgrade to Duet 2 Wifi

@GT1Za
Hey, just had a thought. Maybe try swapping the X and Y motor connections on the Duet, then update config.g like so:

Change:
M584 X0 Y1 Z2 E3 ; set drive mapping
to
M584 Y0 X1 Z2 E3 ; set drive mapping

It would be interesting to know if the issue moves to the X axis, or if it continues on Y. If it moves, I'd be inclined to talk to one of the mods / admins if the board is in warranty and see what input they have. If it stays on the Y axis, then I'm back to being stumped

not sure if that helps. Pretty tough getting to the back of this printer.

The motor is about double the height of the normal ones, but its the standard S5 motor.

Belt looks kind of loose to me.

Your E steps for the extruder is still set to the stock 93ish. The Hemera is 415ish.

Ive always liked the idea of keeping the z stop incase the BLtouch fails. Is there no way to keep both?

No, unfortunately it doesn't work like that. But when configured and wired correctly the BLtouch is pretty reliable as an endstop. As a safety precaution it's a good idea to drop motor current during homing so that if the probe does fail it will just stall the motor without causing damage.

Can you do a quick test of your Y axis? Send G92 Y0 to mark it as homed. Then jog it 10mm and measure the actual distance moved. That will help us verify if your steps per mm is correct.

Your X Y offsets for the probe are improbable. It must be measured. https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Measuring_Probe_X_Y_Offset

@Phaedrux Thanks, I had already adjusted the esteps on the extruder to 409. This seems to be the recommended starting point, but I will adjust this when the machine is finished in the testing phase and correctly wired with wire management in place. But again thanks for the reminder!

I will take measurements now, but Im pretty certain its going just over double length.

I am now completely confused... I did as you asked.
Homed the Y
issued command to move 100, and the plate has moved exactly 10cm

@GT1Za Sounds right. 100mm is 10cm.
Or am I missing something?

@PaulHew haha thats why I am so confused!! if that is right then why am I getting an issue and it only going to 220 and not 500 before reaching the end of the bed??

PaulHew

@GT1Za Please send details of M115

@PaulHew Ill get it up soon as I can. I have dismantled a lot to start with cable management.

PaulHew

@GT1Za No worries.
I was trying to help someone last night and everything looked right but I forgot to check his firmware version!

Can you also repost your config and homing files as they currently are?
