I was printing some ABS on my modified Anycubic I3 Mega overnight, when I awoke to this horror of a destroyed glass print bed…
Now the question remains, how to actually fix this? One part is still firmly attached to the Bed and I fear this may destroy the Bed even more.
And I obviously need a new Print bed, but I can’t find the exact replacement, so should I even get a replacement Ultrabase? I saw that there are magnetic PEI beds available, but I am unsure if it is worth the 80-100€ for this.
Edit: Since the glass is glued to the 1.5mm aluminium heater PCB (and I already had to resolder the broken off wires once) I was looking at complete replacements at first, which why the price is relatively high
I did exactly that to my i3 Mega to attach the magnetic plate directly to the heat plate. I indeed bend the whole thing in the process, fortunately though I was able to fix it (Z-Probe reports a maximum difference of 0.37 now). Don’t recommend though.
The industrial-grade glue they used is an absolute nightmare. If you choose to go that route definitely get yourself a proper heatgun as well as acetone, a spatula and some safety mask (for the acetone fumes). If you got an oven for tinkering perhaps heating the whole thing up to weaken the glue.
Leaving the glass plate where it is and putting something new on top definitely is way easier. Not sure I’d do this a second time myself (probably not).
I might be “lucky” in the sense that the glass appears to already separate at the corners.
Does the magnetic plate warp much under high heat loads? Since I print a lot with PET(G) and sometimes ABS I thought this might be a problem.
If I leave the glass on I might not get to the Maximum temperature, but I ordered some moderately priced magnetic kit already, so I’ll just clip this on top and Test first.
