delta auto calibration rams into roof of printer

[Veti]

check with m119 manually that each endstop is triggerd.
also check that they correspond to the motor assigned to it.
having the endstop on the wrong motor would cause that.

@Veti i have done so previously but i will again, never hurts to be sure.

I'm at a loss at this point. I've never heard of a duet-based delta properly homing, moving in the proper direction for G1 commands, but moving UP for a bed.g similar to yours.

Perhaps @dc42 can offer some help here. Here's very proficient with delta machines (and obviously he knows more about the Duet than probably anyone.)

How bout a video of the behaviour?

[dinlo]

@Phaedrux sure, i'll do it today if i have time after trying out the files from Jay.

I installed your homedelta.g and bed.g on my Rostock Max V3.2.

After making all the values in bed.g no larger than 95, I homed and ran the G32 button and everything went along fine. No crashing.

I can't use your config.g unedited because my motors go the opposite direction, but if you still have no progress, I'll try using it and doing the bare minimum of edits to change it to my configuration.

I'm running a Duet2/Ethernet with version 3.2

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.2 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2021-01-05

So, i think i've found the area where the issue is.

The machine still did the same thing with the config from Jay. I had only modified one thing to fit my machine: stepper direction. After changing this in the wiring (rather than in config.g) so that it's correct when config.g says they "go forwards", calibration worked and i managed to get off a few probe points before i had a structural failure with the 3D-printed adapter i used (it had some minor stress lines after the failed calibrations and one of these developed into a crack). I'll have to consider whether to get the Haydn arms now or order a print from a printfarm (which will probably cost as much as the arms from what i saw last i checked).

should i mark this thread solved now or wait until i've fully verified that calibration works? (will likely take some time)

edit: thanks @alankilian for mentioning direction just as i was wondering why.

or you can check if a forum member is willing to print for you ...

[jay_s_uk]

@dinlo where are you?

[dinlo]

@jay_s_uk i'm in sweden, roughly an hour inlands from gothenburg following E20 in a town called vårgårda

@oliof i honestly didnt think of that
