Hi All,
OK, the next step is to get the spindle working with Mach3, now that I have the index pulse properly setup to read the speed. I have a C11G BOB from CNC4PC and I am not sure how to proceed, here are my problems:-)
1- The VFD I am using ( a 15HP GS3 from automation direct) has an analog output supply of 10V at 20mA max. The C11G has a required input of 12V @50mA. Do I really need another isolated power supply? I feel like I have about enough in that control panel... 24VDC, 24VAC, 12VDC for the drives, 60VDC for the servos, and on and on.....
2- Ive read some not so encouraging things about the C11G's analog capabilities after purchasing it quite some time ago, if I go to the trouble of setting up another PS, will it even work? Has someone out there had success with it? I have 4 of their boards going right now and all the other functionality seems OK, although I had to return one for workmanship issues (pins bent over on IC) and they always look a little funky right out of the box...
Does anyone have any suggestions as to how to proceed? I am seriously considering just switching over completely to Peter Hommans boards and use the C11G in my other lathe which is currently BOB-less.
I've recently received a big order for parts and am feeling the pressure to get this retrofit done, but want it done right :-)
Thanks for any suggestions,
Dustin
