persistent adhesion issue on my Prusa Core One
Hello everyone,
I’m experiencing a persistent adhesion issue on my Prusa Core One when printing ABS:
Setup and settings– Printer: Prusa Core One in a closed enclosure– Material: ABS– Bed temperature: 115 °C– Nozzle temperature: 250 °C– First layer calibrated with 7×7 mesh bed leveling– 6 mm skirt around the part
Problem– At about 5 mm height, the part lifts only on the right side, starting at the corners– The left side remains perfectly adhered– The part is rectangular and almost covers the entire build plate– I’ve flipped the textured sheet (cleaned with isopropyl alcohol) multiple times, but the issue persists
Troubleshooting already done
Cleaned the textured sheet with isopropyl alcohol
Printed inside a closed enclosure (no noticeable drafts)
Used 7×7 mesh bed leveling
Reoriented the sheet by flipping it
Thank you for any suggestions!
Have you seen a one-sided adhesion issue on Core One before?
How can I diagnose potential thermal or flatness variations on the right side?
Which settings or accessories (adhesive, brim, “mouse ears”) do you recommend for a large ABS part?
