• Kits, new
• Machine 1 identified by orange Z motor holders
• Built ok
• Z settings (FYI: -1.8 is lower than -1.7):
  • PINDA offset:
    • says cable tie height which I measure at 1mm
    • also saw a post saying “Make sure the PINDA is between 0.8 and 1.2 mm higher then the nozzle”
    • I want maximum offset to avoid it dragging on questionable print that might complete otherwise so will try 1.2mm, so set it to 1.2mm then
      • Calibration -> Wizard
      • Then XYZ Calibration = FAIL, is dragging paper when sensing first calibration point
    • Set to just over 1mm then
      • XYZ calibration
      • Level Cabration
      • 1.550mm Textured sheet = PLA good
• Per https://help.prusa3d.com/en/article/mesh-bed-leveling_112163/ Settings – Mesh bed Leveling:
  • Mesh (3×3 – 7×7)
  • Z-probe nr. (1 – 3 – 5)
  • Magnet comp. (ON / OFF)

• So some problems with PETG ater a run of successful prints, after recalibration and a bunch of other things found my finger grease had contaminated the textured sheet, a clean with isopropyl and good to go again
