Good morning folks,
I’m reaching out in hopes someone can maybe correct the error of my ways or shed some light on the situation I’m facing. I calibrated the bed mesh using the paper method, calibrated hot, and ended up with a value of around 0.38. I calibrated the extruder and got things looking rather nice. Everything was going great until several prints later on which I had observed the variance was gradually increasing and prints were having issues. I had calibrated with a particular brand of filament, printed a test print which was beautiful and then changed brands to print another. I noticed it was printing a ‘skim coat’ on the first layer and each print would get thinner and thinner first coats as well as during the yolo test in orca, it was just dragging the tiles around. At the end of one calibration test, I came back to find a blob wrapped around the nozzle. The variance had increased from 0.38, to 0.47, to 0.57, and now sits at around 0.63. When I had calibrated the z-axis, we found I needed to lower it a bit more. Remembering this, the nozzle dragging (which luckily it set off a sensor and aborted print) made sense. I also have the following gcode at the beginning of every print in orca:
BED_MESH_CALIBRATE
Is there something here I should or shouldn’t be doing different? Thanks a lot in advance, I’ve been going through hell with this printer but I’m not giving up.
