Can you analyze my pncconfig settings ?
Here are the windows;
1. Base information
Are the settings suitable in the I/O Control Ports / Boards ? (6i25+7i76+7i76)
2. Mesa Card
Are the selections of the board name and firmware true for my combination ?
3. I/O Connector 2
I think that I/O connector 2 is part of one of 7i76 card. Is it true ? I defined 3 motor in this page.
4. I/O Connector 3
I think that I/O connector 2 is part of the another 7i76 card. Is it true ? I defined other 3 motors in this page but i can only test the perivous 3 motors.
5. X Motor
Here are the stepper parameters. I can move the motor.
I can move the y and z motors like these. Pncconfig created hal and ini file. Here are the files.
HAL File;
INI file
Harware connections.
