I began reading some threads, checking the wheels which seem fine and working on squaring the machine. I cleaned out the crumb tray as well. I did see that it is more noticeable towards the center of the machine versus the side of the machine.
I rotated 90* and it is there (near where the ribbon is)… but smaller and only if I rub my finger along the outside I feel a little bump.
Perhaps the design? I designed the SVG myself and imported it in. It worked well. I can’t tell when it started to go off course a bit. I have duplicated the file a couple of times… could that be it?
Not a huge problem, but do you have to have a circle that I could test that you have used?
I’m starting to think it is something that happened to the file along the way from copying it… if that is possible. I just ran a snowman file that I’ll upload the picture tomorrow, but I didn’t get any uneven cuts.
I’m still stuck on this. I can’t find any debris that is messing with the motion along the Y, None of the wheels look cracked or damaged, and the belts look in good shape.
Here are some videos I have taken.
Belts sound like a guitar as one video points out. I push on the top and the bottom part doesn’t move.
Cutting different parts of the machine.
The circle on the score and cut do not complete (Sorry for the bad video and possible crying toddler in the background)
Post-It Note Slip
Here is a post it note cut out where it cuts out, but you will notice when it meets to finish, it does a little curve.
Rolling Manual
With the machine off, I rolled the x-axis to the front and back to listen for any inconsistencies. I don’t believe I hear any and all wheels look in good shape.
Thanks for all the support. Hopefully you have next steps to try. Thank you.
Watching all of your videos it appears that the movement of the head is jerky in both axes. It should be smooth. I suspect you have something in one of the teeth of your drive pulley(s) that is causing one belt to act slightly shorter than the other.
It might just be the video, but it really looks like the head is making a periodic pause or jump.
If it isn’t the belt and the head is making that periodic pause, I would guess you have a current leak that is robbing the steppers of current and they are losing partial steps.
