with the help of a friend the v4 board is now connected and motor is spinning

but im having a new dro issues in mach.

motors are 200 steps / revDirect drive, no gearing.Lea
dscrew is 3mm pitch (1 rotation moves 3mm) waiting to get exact pitch from denford forum
Microstepping is 1/10 (stepper drivers are set to 10)
so:No. of steps per mm is = 200 * 10 * (1/3) = 667

but when I put 667 into steps per in mach the actual machine moves 550mm but I only get a reading of about 26 on the dro
