Hello everyone,
I have CNC based on microstep driver CW5045, which works well with Mach3, but when I want to use LinuxCNC, I have a problem.
LinuxCNC is installed on my PC, I start "stepconf wizard" and I introduce the parameters, when testing individual axes (x,y,z), everything looks good, the axes motors are moving. I finish configuration with save file and .exe generation. I run the generated exe, set estop and machine on/off, when you press one of the arrow keys on the keyboard, the values of the corresponding axis (x,y,z) in the program change, but the machine does not move.
Please for help and guidance, what can be confusing or I need to set up.
Š¢hanks in advance!

Do you have the driver enable inputs connected? This is usually the most likely reason for your problem. The "Enable" input on the drive is actually a disable input. In other words when nothing is applied to the input the drive is enabled, and it is disabled when a signal is applied. The test screen in Stepconfig does not send any signal to the drive enable, so if it worked there, and you have a drive enable configured in Linuxcnc, the drives are probably being disabled when you turn on Linuxcnc. The solution is to simply invert the output signal to the drive enable pin(s). By selecting the invert pin check box in Stepconfig or by adding the apropriate line(s) in your hal file.
For example if your drive enable is connected to parallel port 0 pin #3 add this line to your hal file.
setp parport.0.pin-03-out-invert 1

If you are considering connecting the driver to the picture (.ENA +, ENA-: Enable motor input) - I have nothing involved on these pins

pins I use and configuration:
xstep - 2; xdir-3
ystep- 4; ydir-5
zstep-6; ydit-7
the other pins tune them up that they are not used

Were you using a safety charge pump with Mach3 ?

no, I do not have safety charge pump. In Match3 I just configure the motor outputs and speed and everything works without any problem. My drivers are directly connected to the parallel port.

It would appear, from your photos, you have the power connectors, +V & GND, connected to the driver enable connector.

I'm sorry if I did not understand exactly. Power pins of the driver (+V & GND) are connected directly to the power supply, the pins (A+,A-,B+,B-) go directly to the stepper motors.

Sorry my bad, got confused on which connectors were which......your wiring is ok.

Might be best to post your config file
