I have a Taz5, and I bought the new dual v2 extruder. When I was testing and trying to adjust z height (and the z height of the second extruder to the first) I did a stupid and scratched my glass bed because my second extruder height was so far lower than the first. It actually looks like it etched the first layer of the print onto the glass. Fortunately I did not damage the extruder nor break the glass…
Now I have everything adjusted and level, and the prints are coming out great, except that I’m getting the etched impression on the bottom of my prints because the glass is scratched from that big fail.
I’d like to get a flat glass surface again. I’ve read that the glass can be sanded safely, but I think if I do that, I’ll need to sand down too much and end up with a less than perfectly flat glass surface.
So before I buy a new glass bed, I wanted to know: Can I just remove and reverse the glass? Is the back side also suitable for printing?
