I need to print a bunch of identical items. Rather than printing them one at a time, cleaning the plate, and restarting the print, I would rather start an entire plate of them overnight and pick up the lot in the morning.

The problem is that the build plate is nowhere near flat. Even though it creates a bed mesh before every print and calibrates the z offset, the toolhead is still too close for some parts of the plate and too far for other parts. This causes the toolhead to scrape against the print and often rip it off, creating messes like pictured. This time it also ripped off the thermistor, previously it snapped the hotend in half.

On my last printer I solved this with a sheet of G10, but the bed leveling sensor cant detect G10 causing the toolhead to plow straight through the build plate.

Has anyone else had this defect? Im wondering if this is something that can be fixed or if I need to RMA it.

I was trying to print on the whole plate when it crashed into the part, creating a big glob of plastic and yanking out some cable.

I'm trying to design some cookie cutters and have sketched up this moderately complex/organic shape.

I want to make all these lines 2mm thick so that I can extrude and print this part.

I tried 2d offset but it didnt work for this sketch.
