Calibration error on non-first run exceeds set limit
Hey im running the Marlin4MPMD firmware and the leveling script is showing highly negative values:
Center :-128.16, -128.16 Average:-128.16 X-Axis :-123.35, -123.38 Average:-123.365 Y-Axis :-122.87, -122.89 Average:-122.88 Z-Axis :-123.70, -123.71 Average:-123.705 Z-Error: -0.825 X-Error: -0.485 Y-Error: 0.0 C-Error: -4.8433
the script fails on the second iteration. it also takes forever to go down to the buildplate, although it does not scratch it
I'm not sure if @McSwindler can reply to this or not, they created the autocal script for the Marlin4MPMD firmware, my printer is still running stock firmware so I don't have a way really to debug this script.
Do you know if you have the 16 micro-step board?
If so, you can try running the script with the argument -s 114.28
This will set the steps/mm to the appropriate value.
hi I'm having the same problem even with the steps/mm value

As far as I know, none of these scripts have been updated to work with Marlin4MPMD 1.3.3's default tower rotations.
I just found @PurpleHullPeas that he claim to have updated the p5 one for Marlin4MPMD 1.3.3 I'll give it a try now
The version on this page won't work, either. I issued a pull request 9 months ago that never got merged, so I moved everything to my own repository. https://github.com/PurpleHullPeas/MPMD-AutoBedLevel-Cal
@PurpleHullPeas I started the p5 auto cal and so far didn't get any errors on the first run, so I'm happy
@PurpleHullPeas huh, I thought I'd merged that pull request in, but I see that it's sitting there waiting to have something done with it... guess I'm really on top of things. :/
@TechnoSwiss No worries. I ended up writing a more in-depth set of instructions and troubleshooting for my script on my GitHub page to separate it from Facebook. The version you just merged should still work just fine.
@PurpleHullPeas thanks for your program, it really helped! Had to do it more than once due to one of the bed clips not being leveled with the rest, but for now it's level enough to make close to perfect prints, still managed to print the clips that Dennis published on Facebook and will be installing them as soon as I get the rest of the hardware
@ReadZead Glad it worked out for you. Quality control for this machine coming out of the factory is all over the place, so being able get decent results without the recommended hardware upgrades is really hit-or-miss - hence, all of the emphasis in the instructions on prerequisites and the troubleshooting form.
Hell, I even tried calling tech support about it since some of the stuff I tried just made it even worse wether it was by the community or by monoprice due to the poor bed levelling, and even from what they were telling me, it sounded like they didn't know how either their printers nor the gcode compatible with their printer worked, they said that the reason my bed levelling didn't work was because I had the gcode for it in the start code in my slicer
@ReadZead Just my opinion, but the only truly reliable sources for information about the MPMD are Dennis Brown, Matthew Upp, and Mickey Rozay. People like me and a few others have written guides that have been reviewed by one or more of the above, so I'd also call those specific resources reliable. Even then, the firmware is closed-source and MP/Malyan is constantly changing the hardware, so it's hard for even the experts to keep up.
