Report back and let us know how that worked.
While I hate seeing that everyone is having issues, there is a bit of solace in seeing that everyone is having issues...
A minor z-offset bump has made a difference for me in S3D prints, but still getting some weirdness in FS direct, haven't tried it there yet.
That 'infill'o'clunk' dragging/clunking thing seems to be common to everyone so it is definitely not something we all could have mistakenly changed collectively at the same time. The weirdest part is how it goes back to printing shells and supports just fine and then just goes all to hell again on infill, then back to normal.
Sorry your thread got hijacked Jim, but this is what we were talking about in the other thread too. Not so much a slicer fault, I don't think, but something in machine calibration settings or fcode compiler got changed.
Back to your topic, I haven't seen my plate squishing like that or any bubbles yet, but I did make a mention already that we received no care instructions for the mag plate. I have a bit of 'ghosting' on mine from the weird problems described above, I did give it a quick wipe with some iso alcohol and that removed some of it and seemed to kind of restore it a bit. It looks cleaner anyway.
There was also one post about rods popping off and nozzle burning a hole in it so that is something else to be concerned about. I don't think unattended prints with the mag plate will ever be a good idea.
Like others, I'm switching back and forth between glass and mag plate. Mag when I want to be lazy and don't need great surface finish. Glass when I need premium quality.
