I know Lulzbot is working on a new heated bed (which I’ll definitely buy as an upgrade when it’s available), but the current bed has relatively uneven heating across the surface. Has anyone found any way to mitigate this when you have very large prints?
I’m about 11 hours into a ~20 hour print of what is basically a 200mm x 200mm box - so it covers 3/4 or so of the TAZ bed. I just noticed all four corners are starting to warp upwards a bit. The printer is in an enclosure (unheated, but it retains the heat reasonably well) and smaller parts that are close to the center of the bed print wonderfully with zero warping. The bed had a fresh coat of ABS glue before starting the print.
I may look into using a heater to keep the build enclosure actively heated to a certain temperature, but I’m trying to avoid that since the electronics are in the enclosure with the printer right now and I’d like to avoid rewriting things if possible.
