Got all the bugs ironed out of my latest 3D printer upgrades... The 250 watt bed heater isn’t trying to set my mosfets on fire any more, I beat back the bug in the AD8495 code in Marlin that kept my new thermocouple from reading temperature correctly, and I squashed the jerk calculation control bug (by enabling an alternate calculation scheme) that was causing x-axis layer missalignment. I can now run hotend temperatures up to about 370 C, and bed temps as high as 150 C. Nylon is now easy to print with the bed that hot, and Polycarbonate is still a bitch to get the first layer to stick, but damn is it tough and heat resistent! Do I pick up some Ultem or PEEK and try printing a (breifly) functioning internal combustion engine?
