Nextruder issue, and Homing?
This may be a double post, I tried posting it at like 1 am last night, and when I came back this morning, I received a 404 and couldn't find it, so If it is a double post, i'll delete, and I apologize. But, anyways! I finished assembling my Prusa Core One + last evening, I used the Prusa web app to get the correct HZ with the belts, everything calibrated, except the homing calibration said it was unable to be completed, but then I noticed that the calibration had a green check mark off, so I'm unsure if this is a software issue, and it actually calibrated? or if it's not actually calibrated.
Secondly, and this is more of an issue, and i'm not quite sure what the deal is. The nextruder is making that terrible grinding noise, I went through the entire nextruder assembly again and double checked everything (I didn't take it all apart and rebuilt it, just double checked everything with each step and what I could see with the cover off). But as you can see the nextruder starts to spin, and then it seems like it catches and just grinds and bumps back and forth. Any help is beyond appreciated, seriously beyond appreciated.
RE: Nextruder issue, and Homing?
1. Homing calibration failed because the gantry is not square. You probably skewed it when you tensioned the belts. You must turn both screws by the same amount. Completely loosen the belts, then manually bend the gantry until it is square with the frame, use this as a guide: Adjusting belt tension read it carefully. Then turn each screw the same amount alternating between screws until the belts come under tension. Then only turn each screw 1/4 or 1/8th of a turn, always in the same direction and by the same amount.
2. If I were to guess, you don't have the nozzle fully inserted into the heatsink that or the tensioning screws on the idler are too tight. Make sure it is inserted fully like this
