Loose belt after calibration

Troubleshooting
1

I’ve attempted to calibrate a bunch of times at this point. One of them was successful and I was even able to run the gcode and make a sign. Not enough depth though, so I edited the depth on fusion and went to download the new gcode. It seemed like it crashed when I tried to do that because no buttons on the Maslow interface were working. I refreshed the page and I lost my calibration settings. Since then I’ve tried to calibrate 4 times and it always ends up failing at the end with the top left belt being loose. Unsure what to do at this point. The belt seems fine. The wedge clamp screws were all loose, so I tightened those, but still nothing. If anyone has any information regarding the situation I’m in that would be greatly appreciated

hmm, plugging this in to my online analyzer it looks like it didn’t go a good
grid to the bottom right and had some points where it had significant errors

so this is working, but not an especially good run. I would be checking that
nothing flexed and the belts didn’t catch on anything during the run.

if it works for you, it works, but if not you could try setting the outlier
threshold to something like 2.8 and enter the revised numbers to see if they
work better for you (back up the maslow.yaml first)

To make it easier to pass a good place to start could be to try reducing the values for the work area in the settings. That will force the machine to only take measurements towards the center of the sheet. The trade off is that the work area is then smaller. Once it’s working well in a smaller area we can expand it.
