15,816 | I am building a 3D printer from scratch, the bed will only move on Z and the head will stay at the top of the printer and move X and Y.
How do I modify the Marlin firmware to have the bed lower as it prints instead of lift like most printers. | [

16,559 | My BLTouch was working great. Until one day, it just started showing the right side as being high on every read.
I've tried leveling many times manually and with the BLTouch. But every time I use the bed visualizer, it shows high on the right. I've even rotated the glass build plate with the same result.
Any ideas wh... | [

16,566 | Is there any convention on how to mark an all metal hotend to distinguish it from a hotend with a PTFE tube in the heatbreak? Once assembled for a German Riprap 3D printer, they look exactly the same on the outside. I'm trying to decide on a way of marking them to indicate the difference.
