7i80-DB + 7I76 - PWM Spindle ?

Hi All
Just wanted to update on this issue. The firmware provided by PCW worked a treat.
There is an issue with the direction ie I can only go M3 not M4, I'm assuming I got the wiring messed up but did not have time to check with a multimeter.
Did find out the drive sends out rotation pulse so I'm going to see if I can get LinuxCNC to estimate the RPM and feed this back in to a control loop. (might need help in another topic with this)

Thanks

The 7i80db_16_7i76x3D3p.bit firmware leaves the PWMs direction pins unconnected
I did this because if you don't need the direction pin, its free for general purpose use
and if you do need it, you can generate a direction signal in hal and drive the proper GPIO bit

7i80db_16_7i76x3D3p.bits PWM direction pins (wired to DIR4 on all 7I76s) are
on GPIOs 08, 25,42 for the first,second and third 7I76

Hi All

Final update to this thread, mill is working now. Have done two seperate jobs.

I have purchased a part and tool probe from vers.by, but the part probe seems to have been damged in transport and I did not identify this until transport became hard because of the pandemic.

The video below is cutting stainless steel, its a latching pin used on our Wool Sampling Machines

Again thanks for all the help.
