As I said, most motors with the torque for an MPCNC will have current ratings in the 1.5A to 2.0A range. If the sales page where you purchased the motor did not list it, find the stepper model number and look it up. You need to start with the maximum amperage for your stepper motor. If that 0.9 is really the amp rating, that number is too low for most stepper motors that have enough torque for an MPCNC (as spec’ed by Ryan). If 0.9 is the v-ref voltage, that would 1.8A, which is too high for most stepper motors on the MPCNC. For the DRV8825, that is 1/2 of the current output. V-ref is the read voltage from the stepper driver. You need to be careful about mixing current and v-ref. I have two (non-CNC) projects that use Ramps boards, with zero issues. With that said, there are a lot of MPCNCs using Ramps boards. But the upside is that replacing the Mega board is only $20. A mistake in wiring will often kill the Mega2560, or burn out a pin. The downside to Ramps boards is they are more fragile.

If you purchase your SKR Pro from Ryan, it comes pre-flashed with the firmware, but you would still have to flash your board if you purchase the SKR Pro somewhere else. In addition, these packages include a pre-compiled hex file, so if you don’t need to make any changes, you can use XLoader to flash your firmware and avoid the compile entirely.Įdit: From a performance standpoint, you will see little difference between the Ramps and the SKR Pro board. If you are building a standard Primo or Lowrider, V1 provides pre-configured versions of Marlin here. Ryan has provided instructions for compiling using PlatformIO. Marlin firmware no longer compiles using the Arduino IDE (under Windows).
