Hi, several prints failed. I added a BRIM, but it didn’t help. I changed the orientation, and that helped.
However, prints are still failing near the edge — see the pictures. I lubricated the axes and ran vibration calibration, but the problem persists. Thank you.
Have you given the plate a good scrub lately? Sometimes the reason changing the orientation helps is because there are finger prints or other contaminants on the plate in some spots.
Yes, with water and soap before printing.
The second picture was when it worked? Is the ambient temperature in the room really cold?
Yes, the second picture after changing orientation and it worked. Room temp is about 25 C which is normal. Can it be belt tension issue?
Not usually. Bad adhesion is normally a dirty plate, incorrect temperatures, the z offset or an extrusion problem. With Bambus you can usually rule out z offset.
Are you running bed leveling with each print? Make sure the nozzle doesn’t wobble if you try and move it by hand. There are three screws above it you can tighten. Also just taking the nozzle out and reseating it helps sometimes.
Thank you; you solve it! I closed the 3 screws on the hotend, then system calibration auto bed leveling. Great print with no brim
