I'm struggling trying to get the HAL setup correctly. 1st the vBox slider value doesn't appear to be scaled.
Are the controls for rcpwmgen only rate, width, offset, and scale?
What am I missing, seems like a simple control

Ok, I think I know the issue, The firmware I'm using has the rcPWM on the Mach 3 BOB P11 an opto output. Should be on P1 the PWM for the BOB ???
Is Xilinx Design Suite still used to compile firmware for the 7i96s?

Can one of the step/gen pin be used for a RCPWM signal or perhaps the spindle PWM pin.

My 5-axis bob is a HW-356 Mach3 bob (inexpensive chinese bob). Those pins correspond to opto isolated inputs.The RCPWM outputs 0..3 are on DB25 pins 6,7,8,9
with 7i96s_5abobrcd.bin firmware. These are fast 5V
CMOS buffered outputs on the common Mach 5 axis BOB

After some time away I got this working with the 7i96_5abobrcd firmware. The physical pins DB25 vs. HAL pins had me twisted around.
Just a general question, on this function. To get the servo to physically rotate 180 degrees (+-90) I need a scale of 95. 180 gave ~90degrees, and 90 gave ~190-200 degrees. Is this just the variability of the servo potentiometer?
setp hm2_[MESA](BOARD).0.rcpwmgen.rate 50setp hm2_[MESA](BOARD).0.rcpwmgen.00.width 1
setp hm2_[MESA](BOARD).0.rcpwmgen.00.offset 1.5
setp hm2_[MESA](BOARD).0.rcpwmgen.00.scale 180
