Ender-3 control board replacement

3D printer board upgrade This weekend my Ender-3 BMG extruder stopped during a long ABS print. I expected it was the stepper driver burned out, as it gets fairly hot inside the box. I could get the extruder to take like one step, and thats all. I am running direct drive, as I wanted to be able to print flex with as few issues as possible. Ordered a new control board - The SKR v1.3, which is a cheap 32-bit board from BigTreetech, with support for the 2nd extruder. Still consider the 2nd extruder. Mostly for a wider nozzle / faster print - secondary to make color change easy. But it is difficult to calibrate 2 nozzles. The alternative is the Cyclops hotend. 2-in 1-out. There are 2 ways to power this board. Selected by a jumper. Either from th 12/24V side or from USB. Firmware upgrade I am using Klipper firmware. So connect to my Octroprint server, go to the klipper dir, make menuconfig, make, and pull the out/Klipper.bin file, rename to firmware.bin and put on SD card for th

Printing with HIPS

HIPS is a nice plastic, that is clearly undervalued. It used to be support material for ABS, as it is dissolvable in limonene. But I use it for everything but support. It is much more. Most comparisons says it is almost like ABS but dissolvable in limonene It is a stiff material closer to PLA than to ABS and PETG It is a soft material easy to cut/drill/sand/paint - Even easier than ABS. It is impact resistant despite being stiff It can withstand higher temperatures. Industrial specs says 85C for multiple years It is pretty light compared to other filaments It has less smell than PLA It is supposedly one of the fastest printable materials The color is not as good other plastics. My orange lets me easily see the different levels of infill, as it is very slightly transparent. If you bend it, it will break, and break suddenly. When to use HIPS I use HIPS if I want stiff objects with impact resistance I use it for stiff objects that must withstand heat (like being used in the
