@dc42 That worked! Changing the steps/mm to 80 in config.g and now the auto-calibration stops when it hits the board. Thinking back on it now, I should have known the motors were running faster than they should have, but it never crossed my mind. To confirm, I should run the auto-calibration, then M500 to save the results in override-config.g, and then put M501 at the end of config.g, so that override-config.g is used?
Thank you both so much for the continued help!
@Phaedrux Motors are Automation Technology KL17H248-15-4A. Looking at what I can find online, I couldn't find anything related to 1.8 or 0.9 degree, but I did find a step angle of 1.8° ± 5%. For belt pitch, it's 2mm. Belts can be found here: https://www.seemecnc.com/products/gt2-timing-belt. Looking at the build guide for this printer, it seems like the idlers do not have teeth and looking at my printer don't see any. For micro stepping, this is what I have in my config.g: M350 X16 Y16 Z16 E16:16 I1
@dc42 This looks like a potential issue. I brought the nozzle down to the bed and pressed the Z+25 button. Measuring it, it looks like it went up nearly 65mm. How do I go about corrected/calibrating this?
@dc42 M665 results: Diagonals 291.500:291.500:291.500, delta radius 142.500, homed height 200.000, bed radius 145.0, X 0.000°, Y 0.000°, Z 0.000°.
After homing, DWC reports X and Y at zero, Z at 195. I would make my M665 H value 190 then, and see if it stops before crashing? Also, I'm unsure if I'm using the stand homedelta.g file, so I've attached it here.

@dc42 Apologies for the confusion on my end. I did increase my M558 H value but forgot to mention it. I bumped it up from 5 to 30, as the guide suggested, and still didn't have any luck. I bumped it up to 50 just to see if maybe it needed more space, still crashed. As for reducing my M665 H value, I double-checked both my config.g and bed.g files and there is only one line that has M665. Is there a reason that changing the M665 H value would prevent it from hitting the board, and is there a way to determine what value it should be? Again, thank you for the continued help, it is greatly appreciated!
@dc42 Changed it from 400 to 300, still crashed. Changed from 300 to 200 and it did stop, about an inch away from the bed, never went down and touched it. From there drove itself into one of the vertical beams and I stopped it. I'm assuming this means my M665 H value is incorrect, however in the guide it says to measure the distance from the nozzle to the bed in mm. I get right near 400. Is there something else I should be doing?
@dc42 I commented out the M665 command in bed.g. I don't have a config-override.g, so the one in config.g should be the only M665 command.
When I run G32, it runs straight down into the board, afterward I quickly cut power to the printer to avoid damaging it. I followed the directions on the link you set, with the M665 H parameter being the height of the nozzle away from the board when all three end-stops are triggered. This value was very close to 400mm when I measured, and this lines up with the default value of 400mm when I got this config from SeeMeCNC's site.
With the removed M665 command from bed.g and no change to the M665 H value, as I measured it at 400mm, I tested again and unfortunately still no luck. Whenever the Z-probe is triggered (anything above the value of 0 it seems) a blue light comes on. I see this light come on when the nozzle collides with the board, however, the printer does not stop.
Again, thank you for the continued help
@dc42 The probe triggers when running G30, but not G32. I bumped up the probing speed to 1200 however, it still is not stopping. It is a misconfiguration in my bed.g?
@Phaedrux It's an Accelorometer Probe, unsure about specifics, I cannot find anything on the SeeMeCNC website.

I recently acquired a Rostock Max V3 delta printer and decided to update the firmware (was still running firmware from 2018), however, in my process of recalibrating the printer using delta calibration, my z-probe is not stopping the print head from driving into the build plate. I know the probe is functioning, as I can see the value change in the web interface when I push on the probe. I went through the process of calibrating the trigger height (got a value of -.28) however the print head is obviously not stopping there. I'm new to the duet3d system, so I'm a little unsure of what I'm doing, so this config is mostly copied from the SeeMeCNC guide for this printer. Any help is greatly appreciated!
