I’m trying to figure out what I can inspect or troubleshoot to determine why this issue is happening. This is the first real problem I’ve had with my P1P/S in years, and I can’t seem to pinpoint the cause.
I’ve been printing on a new BIQU “carbon fiber” build plate for weeks without any issues. Earlier today, I completed multiple prints successfully, but now, all of a sudden, the printer is digging the nozzle into the front left corner of the print bed. I’ve always run auto bed leveling before every print since I got the printer.
Firmware: 01.07.00.00
Any ideas on what could be causing this?
Things I have checked:
Re-run full printer calibration
Turned machine off/on again
Checked under the build plate to make sure no foreign objects were preset
Check bed screws to make sure they haven’t moved or loosened up
Printed one of my designs instead of a MakerWorld print project I have been printing
Inspected the hotend for a bend (also checked hotend boot)
Smooth PEI / High Temp Build Plate selected
Like I mentioned I have been using this build plate for weeks and never had an issue. I am stumped and don’t know what to do. . .
There has been numerous reports on bearings sliding out of place. Most of the reports indicate a bed leveling or build plate missing error.
There was a long post I made about it here.
While I am not saying that is your problem, it may be the inverse of the problem I described in that post. You’ll want to check the bearings are flush. Here’s what I mean in your photos. Your left bearing is perfect. It would be important to verify the two others. They don’t have to be perfect but they have to be even with each other.
Hey Olias! It’s been a long time—great to see you’re still active here. I’ve always appreciated your detailed guidance and insights.
I had no idea this was even an issue, so I’ll definitely inspect what you suggested and check out the post you linked. It’s such a strange situation. I was scratching my head because the purge line almost seemed reversed the first time it dug into the build plate. Usually, the “L” part is on the right side, but that time it appeared on the left where it caused the damage. I didn’t watch it scratch the build plate only saw it after the print was done and the next print did the same thing, that’s when I saw it happen.
At first, I thought the print I printed from MakerWorld via Handy might have been the culprit, but that seems like a stretch. Either way, I’m hesitant to reprint it and risk further damage to the build plate—or worse, the nozzle or hotend.
