This cnc mill is 3 axis and Axis are controlled with servo motors and has a umbrella tool changer.
How can we start this project.
Please be gentle and this is the first time with mesa boards with our selfves..
Your help is highly appreciated
I will assume you ordered the go kit which includes the cable and have installed linuxcnc successfully. This is the way I startup a system.
1. Determone if you want to use a seperate 5v power supply. I would suggest it. Select your jumpers and double check you set jumpers on the 5i25 to not send 5v out to the 7i77.
2. Set jumpers on 7i77 to receive external power.
3. install 5i25 in computer.
4. connect supplied cable from 5i25 to 7i77.
5. connect 5v to 7i77 on 5v terminal.
6. connect field power 12 or 24vdc to orange connector for field power making sure your polarity is correct.
7. power up power supplies.
Run pncconf.and go through and select and set what you need on your mill. encoders, limit switches, home switches, servo outs etc....
Start Linuxcnc and fix your mistakes in hal and ini files.
Close your estop input and set it in hal file.
Use HAL Calibration to check inputs are working.
That should keep you busy for a while.
