Can you copy and paste the error message? That should tell us what the issue is

@bar I went ahead and copied the error message into a .txt file (“Maslow_Error_10182024”.txt") so you can see the full extent of the error. I also uploaded the full GCODE File so you can see that as well.

[MSG:WARN: Position error on Bottom Right axis exceeded 15mm while running. Error is 15.041mm
This is the culprit. It’s a pretty common error which happens when there is an interruption in the connection from the controller board to the encoder boards. A quick fix is to blow out the ethernet connectors with compressed air or computer duster and use some hot glue to keep them sealed so dust can’t get in there. A longer term fix is the new JST-XH boards that we just made to solve exactly this issue. The ethernet connectors just aren’t great at handling the dust and vibrations.
Hello everyone, it’s been a little while since I’ve posted on this issue but I wanted to update you all on my progress. Since getting my last response from Bar, I went ahead and ordered the new JST-XH boards along with it’s accompanying connectors and encoder boards. Upon installing all these new components, I am still falling into the same issue as before (See attached .txt file for error), same GCODE is being used. I have also provided a video of where I am seeing the issue present itself.

@bar @anna I’m about at my wits end here and I thought we had narrowed down the issue to just hardware, however, this doesn’t seem to be the case as clearly i’m getting the same problem as before. I’m inclined to think that perhaps the next course of action is to send this constructed unit to you and have you put it on one of your frames (vertical and/or horizontal configuration) and see if you can get it running. The assumption here is that, if you can get it to successfully run a profile and do what it’s supposed to do, then clearly I have an issue with my frame, but I feel like we need to do root cause analysis on this and identify if the issue is with the unit or somewhere else entirely. Question: Is there a way to open up the tolerancing on the unit to accept a larger error value, then perhaps it would run? Just a thought.
Me too 
We haven’t ever seen that error since switching to the JST-XH connectors.
Does the issue always happen in the bottom left corner of the sheet? Have you ever seen it happen in the center of the sheet?
This is certainly possible, but I think we risk breaking something.
Do you have enough space to try laying it flat (even temporarily) and running calibration in horizontal mode? I think that would be a way to test if we’re worried about frame flex both because 1) If the frame flexes the corners will lift up from the floor which is easy to see, and 2) Laying flat it will be quite a bit more rigid
I’m unsure if the issue happens if the home is in the center of the board compared to in the corner. I’m unable to remove my waste board/frame from the vertical orientation and lay it on the ground unfortunately, hence my looking into shipping my unit to you and seeing if you can run it through a calibration and maybe a test cut. This would at least eliminate the potential that the unit is the issue and would focus the attention on the frame. Allow me to remind everyone that this frame is a aluminum extrusion frame so it’s possible that it may not be rigid enough, at least at first glance and from what is perceptible. I may end up making a new frame out of wood since it’s cheap enough just to see if that fixes the issue.

I’m working on a firmware change which can automatically detect how much the frame flexes, hopefully we’ll be able to release that this week which should make it so that you can get a value for how much the frame is flexing.

Awesome, thank you so much! Has this been released yet?
