Topic: Damaged heated printing bed?
Hi y'all's
I just picked up an xyz davinci 1.0a, used off of Craigslist, with a heated bed, and have been printing basically every day with not a whole lot of good outcome.
PLA was printing alright, with maybe a little bit of warping mid print, but decent. I read that using an actual piece of glass as the bed, as opposed to the hard(ish) plastic clear cover that was on the heated bed was a better option, so I replaced the plastic with some glass cut down from a photo frame. The original hard plastic had cuts and ridges all over it, anyway. It just peeled off.
I recently tried printing with ABS in order to be able to use the printed parts in a hot interior of a car, and have been having problems all over the place
I read that an ideal print bed temp was 104, with an extruder temp of 240, but was having first layer adhesion issues, so I upped the bed temp to 110. I also went from using an abs slurry to a proper brim printed first, and it seemed to make it stick better.
I also made sure to keep the box closed, used the little side cover rounded rectangle things, and turned off the extruder fan in the print settings, to keep it nice and warm inside.
But as you can see, the glass has cracked, and it appears as though the heating element has burned along the top right corner? It may have been there before, but I can't remember. Also, my print has sagging issues mid print, which ive just learned is probably from too fast of a print, and probably too high of an ambient temperature
But more importantly, does that burn mean the heating element is borked? Is it heating unevenly now, or something? I will replace the glass again, but will it be pointless? Do I need a new printing bed? If so, can I replace it with a better one?
I realize this is a lot of information, but any help would be very much appreciated.
Cheers
