Redone from Old gmoccapy and all working correctly. So will try from there.

I would not permanently enable the pwmgen with setp  but rather enable it by
connecting it to spindle-on as shown.

Inverting the PWM output and using the STEP- pin is needed because it guarantees that the
PWM pin is low before LinuxCNC is running, during power up, and after a fault (watchdog bite)

This is controlled by the homing parameter settings in the ini file:


linuxcnc.org/docs/html/config/ini-homing.html
 

How’s it going.  So, I'm trying to make my mill use only one limit switch for both the minimum and maximum travel of the table.  Every time the machine is homed the table moves to the minimum hits the switch it then does a second shorter slower home cycle but then parks with the switch engaged.  How do I make it so after the last short slow home cycle it then parks so the switch is not engaged?  I need to have it parked off the switch so I can configure it to also serve as my max travel limit switch.  If I’m configured for the same limit switch to also be the max I can never move the table after it has been homed. 

Which setting or file do I need to modify to make this functionality so lates say immediately after homed move slowly till the switch is disengaged?

 

ooh ok thanks

yeah oversight, should be channel 1 if im using step/dir4

# Enable PWM generator on channel 1
setp hm2_7i96s.0.pwmgen.01.enable true

or do i not need this command if im replacing it with the invert

# invert pwm output
setp hm2_7i96s.0.pwmgen.01.out0.invert_output true

to get the most out of qtdragon's tool handling, you need repeatable tooling and premeasured tools.

With Tormach TTS tooling, they sell a small granite plate
tormach.com/small-granite-surface-plate-...tool-hole-31713.html
And you use a height gauge to measure the height of your probe and your tools
en.wikipedia.org/wiki/Height_gauge

TTS can be used in R8 and MT3 spindles found on small machines, many people use at home.

This does work a treat when you have it all set up.

There's no information that I can recall for cross compiling Linuxcnc.

When compiling Linuxcnc for the RPi platform (4/400 or 5) I've either done it natively or via QEMU.

For those that are unaware Buildroot is a cross compiling system for building Linux file systems, generally aimed at embedded systems.

Nah, but perhaps PCW did!

there is an error in the commandtry this, it doesn't give me any errors
