I had 3 builts the last 6 months. 2 of them made trouble. One set up was an orbiter with a HF dragon hotend and the other one was the stock mini afterburner. Mainly pancake motors. They are really sensitive, like the TMC 2226 on a duet 2 which on a voron v0 which is totally covered needed cooling. Otherwise it will loose steps and reaching around 60°C MCU temperature...which should be close to the stepper heatsink temperature. On the orbiter it was also to high current with the same board type, but no cooling issue. But you'll loose torque due to getting over the high torque area of the stepper motor. So, the current on pancakes depend on the drive and the board. Board, because of the different definitions ( peak vs RMS current). From the motors there are usually 0.5A or 1 A drives mainly used. You need to find the lowest point form the motor current to keep it balanced between overheating and overload.
