Hi their
I bought Usb cnc kit from RATTM MOTORS , Know i got trouble on connecting motor driver with the controler.
my controler is UCNCV4, FMD2740C stepper driver, the controller has only 4 Pins connections CK+,CK-,Dir+,Dir- But the stepper driver has 6 Pins Sp+, Sp-, Dir+, Dir-, EN+,EN-, SO where should i attach the "Enable Pins"?
the controller manual says it uses ANODE COMMON connection, the motors didnt move it looks like in HOLDING STATE Hard to rotate . the kit uses Only Planet CNC Software
since this is my first cnc project i need help
I Hope the support stuff give me solution on it
