Prusa i3 mk3s+ not moving up enough per layer
Hi, I have been having problems with 2 i3 mk3s+ printers for a few weeks now and I am completely stuck on what the problem is.
Whenever a print starts the second half of the purge line becomes blobs and I hear some noise from the extruder. Then when the actual model starts it OK for a couple layers before it seems to print inside the previous layer. Then it simply start to X and Y crash continuously or just rip the model of the bed.
It seems the printhead pushes down on the print. I have tried getting new trapezoid nuts to tighten the Z axis, even gotten brass versions, to no prevail. Does anyone have any ideas what the issue could be or have had similar experiences?
Clean the print sheet, *really clean* the print sheet, and try again. If problems persist run the built-in first layer calibration routine and show us the result *on the print sheet*.
Cheerio,
