X-axis error

Post by z0rak »

Hey all,

My Felix 2.0 worked great for a couple of weeks, and then started exhibiting some weird behavior. The closer the extruder gets to the frame, the worse the errors in the x-axis seem to be. In the pic below, the object printed in the center seems great, but the two objects on the right were printed in the same area, and both have serious x-errors. I thought it might be the x belt, and I replaced it to no avail. The y-axis appears to be fine in all areas. Any ideas?

Looks like it's missing steps and therefore slowly developing an offset over the course of the print. Check for binding of the carriage, proper tension of the belt, and also check where the current is set on your x-axis potentiometer and possibly adjust that too, although frankly you can get missed steps from either too high or too low current.

Also check the grub screws on the pulley they can come loose

Thanks seaton, that seemed to be the trick. Tightened it up when I replaced the belt but it came loose again in a surprisingly short amount of time. Anyone see any reason why I shouldn't put a bit of blue LocTite on it to hold it in place?

I was think of doing something along the same lines myself. I had a couple of spare grub screws so I replaced them first and since then no problems. I do think I'll put a dan of something to stop them working loose over the long term

The belt is too tightened. Try to turn your (turned off) printer from side to side, extruder should easily slide on the rail.
