Hi

I was able to use the DrufelCNC software to control the Stepper motor by NVСM4 V2.1 4 AXIS controller.
I tried to upgrade firmware by using Mach3Mill.
I mistake to use the firmware-NVUM_V2-USB-BIN.bin to upgrade the NVСM4 V2.1 4 AXIS controller.
The NVСM4 V2.1 4 AXIS controller cannot connect to DrufelCNC software.

Could you share me the firmware BIN file of NVСM4 V2.1 4 AXIS?

Thank you
