@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)

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.

@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

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

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

1. G28 (as stated)
2. the axes goes up to the endstops (these are optical and are triggered by a shim on top of the carriages, hard to take a photo due to them being black)
3. they dont stop at the endstops or wait for any other axis (i.e. if x reaches it first, it hits the roof first)
4. i shut it down

2 included images showing (well, trying anyway) the shim and a carriage hitting the roof

dunno if you can even see it but that black shim on top of the carriage reaches up and hits an optical switch above the roof

when it reaches this point the steppers just grind away until i shut it down

as for earlier versions, no. I immediately upgraded to 3.2.2 since that's what the instructions said

i have the generic config files that came with the board but they were set up for a cartesian.

@garyd9 i measured the arms as best i could with what i have available, i don't have an exact tool to measure them (my longest calipers are 300mm) but believe that's accurate to at least 2 mm, i should be able to make a jig and reglue them if needed.

the 437 comes from me jogging it from homed height to within a millimeter of the bed.

regarding the G28, i made the change and it homed properly before hitting the roof again (now at a lower speed and with M913 on)

Also, i tried the commands you suggested, it moved in the expected directions but i can't measure how accurate the movement was.

@garyd9 said in delta auto calibration rams into roof of printer:

M665
M666

M665
Diagonals 440.000:440.000:440.000, delta radius 227.000, homed height 437.000, bed radius 185.0, X 0.000°, Y 0.000°, Z 0.000°
(seems my z height from the previous step wasnt saved?)

M666
Endstop adjustments X0.00 Y0.00 Z0.00, tilt X0.00% Y0.00%
(i assume these values will change only after delta calibration?)

i apologise for the late reply, i have to go to my dads place physically now due to a forced windows update changing some settings i was relying on to remote in.

@Phaedrux i have used G30 a few times and it probes the bed properly
