Hello,
I'm trying to set up a spindle on a mill using a step/dir servo
I've managed to make it ramp in, using but i'm not sure the way to ramp out
Ideally I want M5 to ramp out, waiting for the spindle to deactivate stepgen.
As i need rigid tapping too, it's very confusing for me at this time
Background :
The machine I'm working on was retrofitted with linuxcnc 5 years ago (3 DC servos on axes, 1 three phase servo on spindle, +/- 10 signal for all), and everything goes well till summer 2020 when one DC driver fried both 7i77 and itself and 3 phases driver seems like to be near to death
I've changed every motors and drivers for AC 3 phases servos, tried to make them working with +/- 10v, and then figured that 7i77 didn't count anymore on some encoders inputs (worse, moving MPG on encoder 02 increased encoder 00 counts, so really hard to tune the system)
As I had a 7i76 laying around, I'm trying to redo my config with step/dir signals
I've added a 7i85s to read encoders, but closing loop is not done at this time on axes, I'm just trying to complete it on spindle first.
Thanks
