Destroyed my Glass Print Bed - What to do now
(lemmy.zip)
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 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.
The magnetic plate indeed warps, not due to heat though but the material on it warping. I saw that on both the i3 Mega as well as a Prusa MK4S with PETG and ABS. Printing big solid objects close to a corner would cause the corner to be lifted up, as the warping of the object is often times stronger than the magnetic plates. Probably gives you an idea of how much force a glass plate has to withstand, especially with badly warping materials like ABS. You can counter this issue with some strong clamps. Doesn't happen on most prints anyway, only on really large and solid ones. The magnetic adhesion in the center is strong enough for anything.
I just removed the Glass plate, not really a big job in my case.
Almost all of the glue stayed on the Glass and the remaining glue was very easy to clean with Acetone.
