i bought the UMO+ printer with the intent to add dual extrusion and i was kicking myself for it when i started reading the forums after the purchase, i'm waiting for it to be delivered. The more i think about it this shouldn't be much of an issue, yes i will have to buy the heater and thermocouple to match the UMO+. I don't care much for power bricks so I am planning to install an enclosed power supply (24v, ~350w because I can) which should be able to power anything I add to the printer. I am assuming the heated bed on the UMO+ is the same as the one in the HBK which uses 24v as I understand it and the HBK includes a pcb that steps down the 24v to power the electronics. Does the UMO+ have the same pcb to step down the volts, if not how does the UMO+ accomplish this since by all accounts it cannot handle 24v without modifications? How does the UMO+ provide 19v to the electronics and 24v to the HB? Are the UMO+ electronics capable of powering/ controlling dual extruders and a HB at the same time? thanks in advance.
