Hi, I find solutions to problems on a daily basis but I think I've hit a wall that's why I'm writing my post here.
I have a noname cnc machine and it works fine with windows and winpc-nc light. However, this version only supports flat files, it does not read 3d files. So I decided to find a solution to this problem. I installed elstcam but unfortunately there was a configuration problem and I decided that it would be easier to install linuxcnc and solve the problem with flat files. The device itself can do such things because I ran the winpc-nc application in the economy demo version and it was able to open a 3d file and handle y-axis paths that had a decreasing height.
Now for some technicalities:
the computer on which linuxcnc is installed is a Dell Optiplex 755,
cnc controller is connected via LPT port
The controller driver is A3977SEDT
The stepper motors are SM57HT76-2804A
Installed the latest version of linuxcnc correctly, started the stepconf setup. Based on the Datasheet, I will complete the information about the signal times for the driver, I have correctly set the LPT port address, pins for the LTP port in accordance with what was in the winpc-nc application and all speeds and steps. Then I click engine test and no reaction. Only "hear" as if some "contactor" click in the stepper motor and that's it.
I have a strange impression that there is something "extra" that causes winpc-nc to work after installation without any super configuration (of course I have to parameterize the device) and other applications simply do not work.
