Hi,
I find some information about this stepper motor driver :
I/O Ports:
DC+:DC power positive pole
Note: Must guard against exceeding 45V, so as not to damage the module.
DC-:DC power cathode
A+, A-:Stepping motor one winding
B+, B-:Stepping motor other winding
PUL+, PUL -:Stepping pulse input+5V (Rising edge effective , rising edge duration >10μS)
DIR +, DIR- :Stepping motor direction input, voltage level touched off, high level foreward , low level reverse
ENA+?ENA-: motor free
Typical Connection
I looked at CncNet_XP_Vista_7.dll source code on GitHub, and this plugin has to communicate like this.
Can you control voltage between DIR+ and DIR- when you use Mach3, and when you use Jedicut, with the computer you use at the beginning (when motor run perfectly with Jedicut), and in 2 direction (CW and CCW) ? You should see constant 0V in one direction, and constant 5V in opposite direction.
When you use Jedicut on another computer, you have to change speed settings if you don't use external timer because in this case speed is controlled by processor. If you lose steps, speed values are to low. Increase value in Jedicut to obtain slower speed.
