Mesa 7i96 with SPINX1 to control spindle speed

Did you set a high spindle speed?

The stepgen errors are because you set too wide step pulses for the
requested step rate (the requested step rate is physically
impossible without violating your specified timing)

I think that is coming from my XAxis stepgen which I am not concerned about. I just am trying to get the spindle working with the encoder. In the spindle section I have it set from 70RMP to 2800.

[SPINDLE]
OUTPUT_TYPE = 1
SCALE = 2800
PWM_FREQUENCY = 5000
MAX_RPM = 2800
MIN_RPM = 70
DEADBAND = 0
P = 0
I = 0
D = 0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
MAX_ERROR = 0

I am trying to just focus on the one thing at the moment. I usually create my config with the pmcconf tool, but I didn't think it could handle the PWM firmware, so I used the 7i96 one.

You also said set scale to 2800, I thought that was for the encoder, that is why I had it at 1600.

I have an appointment to go to but will try later today and let you know how things work out.

Are the settings for the encoder under the spindle tab?

The other issue was my configuration settings are not loading in when I load my file.

The configuration information still isn't coming in when the ini loads for me.
I am also getting the quotes error on the line

I fixed this one, but this is the line:
loadrt [HOSTMOT2](DRIVER) board_ip=[HOSTMOT2](IPADDRESS) config="num_stepgens=[HOSTMOT2](STEPGENS) num_encoders=[HOSTMOT2](ENCODERS) num_pwmgens=[HOSTMOT2](PWMS) "

Also, this setp line keeps having two in it.
setp setp hm2_7i96.0.pwmgen.pwm_frequency [SPINDLE]PWM_FREQUENCY

Here is the surrounding parts, maybe a value is missing and picking up the next line.

setp pid.1.error-previous-target true
setp setp hm2_7i96.0.pwmgen.pwm_frequency [SPINDLE]PWM_FREQUENCY
setp hm2_7i96.0.pwmgen.00.scale [SPINDLE]SCALE

Also, the line in the io.hal tries to redo something I think is in the hal, unless I comment that out, Linux CNC crashes.

You're more than welcome on the testing and feedback. I wish I knew Python better, but I don't. I'm happy to do what I can to assist.
