Overnight my new X1C has developed an issue where the toolhead strikes and drags across the printed part, ruining the print. You can feel and hear the bed vibrate as the toolhead drags across the part.
To make sure this wasn’t a calibration issue, I ran the bed leveling and auto calibration.
Additionally, to make sure this wasn’t a slicing issue, I reprinted a gcode file that worked yesterday and it is now experiencing the same issue. I have tried multiple rolls of filament, including rolls that printed the same part without issues yesterday. Layer height is 0.18 which should be no trouble for this printer.
After that, I did the belt tensioning procedure per the Wiki, also to no effect. I also lubricated the z-axis screws.
Interestingly, first layer always prints perfectly, so I don’t believe it’s a bed levelness issue.
Not sure what to do about the X/Y belts; I have done the belt tension procedure per the Wiki twice now.
The first layer prints normally, then during the second layer, the nozzle strikes the first layer as it moves across and kind of “bounces”. The gaps you see are where the nozzle is hitting the first layer, then it lifts up extruding a small amount, then hits the first layer again, etc. If you touch the side of the bed while this is occurring, you can feel a buzzing vibration only when the head is doing this “bouncing”.
Is it same pattern in same spot for different prints? Could there be contamination on the build plate thats causing first layer to lift into the nozzle path?
Just came accross this issue again on my X1C when running 100% infil on rectangular infill, if anyone has this issue again soon. Changed infil to concentric and all good, had a swap around to different infil types and again all good, soon as you swap back to rectangular it has a ■■■■ and drags accross the print.
