Hey,
Working on the final calibration of my dual hotend upgrade. Ive had some weird snags along the way and found this group to get some feedback. G+ groups were always more helpful then FB.
Prusa I3 running Marlin on a MKS GEN 1.3 board. All Geeetech parts.
-I have a weird issue with one hotend(E2) heating up fast then the other(E1).
-I also have weird periods of time in which my printer loses all sense of up and down. It start inverting one z axis and not the other(NIGHTMARE!) and some stepper motors just start seizing then dont respond. After a couple power cycles and a host reset Id be back in business but then having to re-calibrate.
Someone said I might be under powered. the board is rated 12-24v the psu is dual 12v output. I have both going into the board.
