Hot end Slamming into the rails...
Posted: Wed Jan 25, 2017 8:19 am
My v3 was printing perfectly fine until yesterday when the hot end started scraping against the printed part just over by the Z rail. After a few layers of scraping like that suddenly the hot end just kinda floated up a few inches and started printing in mid-air before I cancelled everything. Come to find out, the co-worker that put it together had twisted the belt on the Z rail a full 360 degrees when assembling it.
I fixed it but the belt has some visible wear along one half of its width, but it seems to hold tension just fine and has enough teeth to still grab the gears. But now when I try to calibrate or even send the G29 command the hot end goes to the X rail, travels down and taps the bed, comes back up and slams itself into the X rail really hard. Here's the code below. Any suggestions???
