First layer GCode generated too low? #474

Open marsrp1 opened 1 year ago

marsrp1 commented 1 year ago

I'm not sure what exactly the issue could be. I have an Ender 3, and put on a brand new PEI bed on it. I set the offset and such, and printed a small thing from Cura to test it. I wasn't happy with the bottom surface, so I wanted to generate the first layer code from this site to have a 'baseline' to tweak. I used the same settings as in Cura, G29 to probe the mesh and 0.2 height initial layer. HOWEVER, while in Cura the print is alright, the code generated by the site... was too low, permanently damaging my new bed by dragging the nozzle against it, as if it either didn't respect the bed levelling or probe offset. FirstLayer.zip In this file, there are 3 files, the first layer gcode generated by the site, as well as gcode generated by cura for a successful print. What could be the issue here?

Hey @marsrp1 ,

after opening firstlayerPEI.gcode in your zip the generated GCode in PrusaSlicer GCode Preview I saw that the height is indeed 0.2 mm, but the width is 0.36 mm. Which makes the first layer 180% width of the heigth. This is also the same as the generated GCode on the "first layer" Page. (seems this Information is missing on the Page)

The CE3E3V2_cube.gcode has a height of 0.2mm as well, but a width of 0.430 mm Check if your Cura Settings has the same width and height as the Test Print on the side.
