delta auto calibration rams into roof of printer
-
@jay_s_uk oh hey, i must have missed that, i saw your blog just as my fourth hotend blobbed itself to death and it was actually what tipped me over the edge on a duet board (that and the possibility to use the effector+v6 on the pred while the duet goes into a future sk-go). I used your guide for most of the predator-specific wiring (like the mentioned endstops) and it all worked first try. (note: i read through the blog again and realised i somehow missed a lot of updates, having last read about when you used the stock effector)
I will try your config tomorrow and return with the results.
As for the Haydn arms, i am planning to buy some either when shipping isnt mad expensive or when i've saved enough to have $250 just laying around (which might take a while as i'm saving for a house rn)

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?
-
@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 ...

@dinlo where are you?
