I´m trying to find a good stepper motor for my custom CoreXY, that have a print bed of 600x400x400mm (for print RC car bodies). At first, I intend to use in the XY axis the **MKS** TMC2100 (LINK), that has this setup:
The calculation method of driver current: i=Vref*1.9/2.5
Default Vref is 0.65v, Max 1.3V,Min 0.
Default Current is 0.5a, Max current is 1A.
I selected previously the 17HS8401 stepper motor (LINK) that has 1.8A, but i´m afraid that it´s not a good match, since that this article (LINK) tells to select a motor with a current rating no more than 20% higher than the recommended maximum stepper driver current. This gives that the stepper motor shoud have about 1.2A. I think this motor will be a good mach for the DRV8825, but not the MKS TMC2100, right?
I´m afraid that this drive has a very low amp limit for the size of my printer, because i think that i need to have a high torque motor (44Nm+?). So, can anyone recommend some good stepper motor for this driver? Or i shoud give up the MKS TMC2100 and use some other drive with more amp limit?
Thanks!
