Which model did you use and did you print any parts to mount them? Do you have any pictures showing the mounting locations and cable routes? The last thing I heard about the reason why servos were switched to steppers was that it was related to wear and life, I'm presuming the gearboxes were wearing out. Should be fine to use these with steppers though - the only special consideration is that the encoder axis doesn't match the stepper axis so the CoreXY motion needs to be calculated first but that's not an issue.
Hi..as per my knowledge Hemera comes with a standard heater and fan, whereas the ToolChanger utilizes premium heater cartridges (24V, 30W/40W) and short connector fans (24V clear 40x40x10mm), these will need to be bought separately. prototype pcb
