My maslow keeps loosing position of the belts while doing cuts. I’ve attached a video of it losing position as well as the output from the serial logs.

I don’t think that this is a magnets issue, but if it is there is an easy way to check. Just press Actions → Test and it will check to make sure all of the magnets are detected.
To me this looks like the machine doesn’t have a good fix on the anchor point locations and so the belts aren’t staying tight.
I would make a backup download of your Maslow.yaml settings file and then try running the automatic Find Anchor Locations process again and see if that fixes it

This video was taken immediately after running a ‘calibration’. I can do it again if desired. I did have an issue after the video where the arms wouldn’t retract until I cranked the pulling force up to 1400. I think you’ve said in some of your video’s some of the machines can be ‘tight’ I suspect that mine is one of them.
Let me know what other information you need. I can do all sorts of tests and experiments, fiddle with things, disassemble reassemble. I just desperately want to get this thing ironed out as I’ve got so many ideas in my head I need to build. lol
I did notice as I¢ve been extending the belts, they do feel like the skip. Maybe I need new belts?
it may be that they aren’t on the spool sanely
the maslow rotates the sppol, but then it’s being measured by the roller/magnet.
It would be very hard for the belt to skip on the roller. you would have to have
stripped the teeth off of the belt, and then something else would have to
happen.
Let’s try a grid size that is a similar aspect ratio to the frame. Maybe lets try 500x1000 so we get more measurements out to the edges where the belts are somewhat slack?
hi, I tried it too. I switched to 1.12, it took a while before I got the hang of it, but I’m calibrating 800x400 with a 5x5 grid. Fitness ended up around 0.85. Frame 4.4m x 3.6m concrete floor. When moving in one direction, the belts sag in the opposite direction, when I go up there, it loosens so much that I have to stop so they don’t get tangled. I have both 1500 forces.
Yup, the larger (1400mm x 600mm 7x7) grid seems to have fixed it for me!
It’s annoying that we ask you to pick your own grid size without really any guidance on what is a good size. I will work on making it so that the machine picks a reasonable size automatically so it’s not something we have to enter anymore. There is no reason for it not to do that automatically…I just need to do some testing to figure out what is a good size
