Cool, thanks for the reply 🙂

where is this part from? what format is ist? have you tried opening and "repairing" it using 3d-builder (from microsoft store)?

Have you modified anything prior to this? Updated Firmware? Updated Slicer Version? Any small change? Is the Extruder still turning? Is the Motor getting too hot? Sry, i just have too many ideas, as i am not that good at fixing your issue remotely - and i have only one Printer and is that rarely making problems. The only Problem I had was a cheap filament that was suddenly only 1.2mm in diameter over a few cm instead of the normal 1.75mm - but this made me aware of the extruder tentioning-screw (i just tighten the extruder a bit more for this cheap TPU).

Is the printed inside getting thinner or is it all the same thicknes as the outer edges? --> Is the nozzle touching (or almost touching) the build plate as the plate is getting warmer and possibly bending/warping upwards? You can try to calibrate the printer after turning on the heated bed for at least 15 minutes...

Hi, you could move the start code purge line further away from the edge/clips by increasing the X-values - currently it draws a line at 0.1mm and a second at 0.4mm (distance to 0=home of X). The second option (what i use) is to get rid of this purge line in the start code and use a Skirt (Bluld Plate Adhesion in Cura - I set two lines with a distance of 10mm). This way the purge line is not wasted material if i switch to a brim. Option 1: ; Ender 3 Custom Start G-code with purge line 20mm from the edge G92 E0 ; Reset Extruder G28 ; Home all axes G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X20.0 Y20 Z0.3 F5000.0 ; Move to NEW start position G1 X20.0 Y200.0 Z0.3 F1500.0 E15 ; Draw the first NEW line G1 X20.3 Y200.0 Z0.3 F5000.0 ; Move to side a little G1 X20.3 Y20 Z0.3 F1500.0 E30 ; Draw the second line G92 E0 ; Reset Extruder G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X25 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish (added 20) Option 2: ; Ender 3 Custom Start G-code without purge line G92 E0 ; Reset Extruder G28 ; Home all axes G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G92 E0 ; Reset Extruder Hope this helps a bit.

I am also missing (or not finding) this function in Cura. I need multiple Top Layers to make my more horizontal shell sections stronger, but i want my print to have an open top so i can glue it to the next part of this multi-part-print and fill it with epoxy later. With a closed top the epoxy wouldnt get to the next part and it would take more work to prepair (drill holes for example). So if someone has a solution to this i would really like to hear from you 🙂 My solution for now was to make the lower part of the two half-pieces 1mm higher, slice it with my desired 5 top layers for a more stable shell and then remove the last 1mm by editing the GCODE-File (I removed 5 Layers with a Layer Height of 0.2mm - i call them waste-layers for now). Just pay attention to the last Extrude-Command! I had to copy the first extrude value of the lowest waste-layer to the extruder value after the last waste-layer - this way the now unused material doesnt mess with your print when the last layer is finished. Maybe i add a screenshot to explain this better later. Maybe some printers use relative positioning for the extruder, then this step is not needed...
