Hi! I'm building a standard C-Beam kit and have a question about the current draw of the stepper motors. I have 3x 4.2A NEMA 23s. It says 4.2A per phase. I also have a 24V PSU that can supply 15A. So my questions are: 1. If it says 4.2A per phase and the motor has 2 phases (4 wires) then could it potentially draw 8.4A? 2. Will the motors draw 4.2A all the time? Or just when moving? Or just when moving and facing resistance? Or is it like a sliding scale between 0 and 4.2A when it reaches its maximum torque? 3. If I use a Synthetos gShield with TinyG, with DRV8818 drivers (2.5A per motor phase), will this supply up to 2.5A and then hold it? Or will it trigger overcurrent protection and just stop? I guess what I'm wonder is: if I'm not pushing it to the limit, will it run with these steppers, a 15A PSU and a Synthetos gShield? Or will it simply not run at all without smaller stepper motors (or larger PSU/drivers). Thanks!
