Need help diagnosing an issue
Hello all, thanks for taking the time to help me out! I am a relatively new printer and built my Mk3s this summer during lockdown. Since the beginning I have had some strange issues with Z axis calibration, where during testing, the nozzle would scrape the paper laid over the bed. This seemed to be resolved by adjusting the PINDA, but now once again prints have dated to fail when the nozzle will catch the prints after the first few layers. I have also (seemingly, I'm not sure if this is normal) had issues with power. Whenever motors are moving, the heatbed indicator will dim. Whenever multiple axes are moving at the same time, the motors seem to brown out (especially during calibration). I'm not sure where to go from here and would appreciate any insight. Thanks!
RE: Need help diagnosing an issue
Is the Pinda clamped tightly in its holder? If it's loose, vertically, it can cause all kinds of issues. Also, since the threaded part is what's clamped, if you move it up or down slightly, it may work its way into one of the thread impressions inside its clamp.
Also, be sure that everything else mechanical is good and tight and that the belts are tensioned properly.
