7i96 step + or -, + other question

First you need to enable just 4 (or 3) stepgens

Then you would need to:

# set step4 pins GPIO mode to output
setp hm2_7i96.0.gpio.025.is_output true
# link software PWM pin to step4 GPIO bit
net lowfreqpwm hm2_7i96.0.gpio.025.out pwmgen.0.pwm

You would also need scale the PWM and link the spindle speed command to the PWM
generators value pin

Ok, I'll give it a shot.
Currently 0to3 are set for machine axis stepgens

Just to clarify when you say enable you mean enable in hal? or is there a specific firmware that has to be flashed besides the two available in big John's tool

enable in hal (on the hostmot2 driver command line in the hal file)

thanks,

this is from the 7i96tool hal

loadrt [HOSTMOT2](DRIVER) board_ip=[HOSTMOT2](IPADDRESS) config="num_encoders=[HOSTMOT2](ENCODERS)num_stepgens=[HOSTMOT2](STEPGENS)"sserial_port_0=[HOSTMOT2](SSERIAL_PORT)

i tried this stepgens=4


loadrt [HOSTMOT2](DRIVER) board_ip=[HOSTMOT2](IPADDRESS) config="num_encoders=[HOSTMOT2](ENCODERS)num_stepgens=4"sserial_port_0=[HOSTMOT2](SSERIAL_PORT)

it looks like its loading the 5 step gens still, as i get an error output 25 not found

this is from halcmd show all
hm2_7i96.0.stepgen.04.direction.invert_output hm2_7i96.0.gpio.026.invert_output
hm2_7i96.0.stepgen.04.direction.is_opendrain hm2_7i96.0.gpio.026.is_opendrain
hm2_7i96.0.stepgen.04.step.invert_output hm2_7i96.0.gpio.025.invert_output
hm2_7i96.0.stepgen.04.step.is_opendrain hm2_7i96.0.gpio.025.is_opendrain

Looks like that command line is busted somehow (missing spaces?)
and if num_stepgens is not specified it will enable all

It also looks like this should be done in the in file

Thank you,

I probably won't get to mess with it for a little while. But i think I will have to start there first
