setting up rpm readout was created by rotccapt
Hello all, I am trying to add an rpm readout on axis. after finishing step config, axis fails to launch. i am using a hal effect sensor with a single magnet to generate the signal for linuxcnc. during stepconfig i added the pyvcp spindle speed display option. i am using pin 15 for my signal pin and set that to spindle phase A. I have verified with hal meter that i get a pulse from the sensor, true when the magnet is off and false when the magnet is on the sensor.
thank you for any help
attatched are my files and the debug report.

The error is this:
I suspect you intended to have
net spindle-at-speed => motion.spindle-at-speed
in your main hal file but forgot
custom_postgui.hal:20: signal 'spindle-at-speed' not found

net spindle-at-speed => motion.spindle-at-speed

i do not need that feature, all im looking for is a rpm read out so i know how fast my spindle is running. i have to manually adjust my spindle rpm.
do i need to comment out that line in the postgui.hal file to make it work? thank you for the help

You could replace both lines in the postgui.hal file with
setp pyvcp.spindle-at-speed-led true
setp pyvcp.spindle-at-speed-led true

I did not quite understand what you were wanting me to do, so i ended up just cementing out those two lines, i did not need it anyways. Everything is working great now. thank you for the help

Hello again, after some issues with my original machine, I decided to build a new one. I am having a problem with the rpm read out on my new machine. During the upgrade I changed to a cnc4pc c11gs board from my hobbycnc ez board. After some fiddling I finally got the pin to work and indicate on hal meter. My issue now is that the rpm read out is not right, My read out is reading 170 rpm when it should be 17000. I replaced the "post gui hal file" that step confg created with the one from my old machine, which worked perfectly before, so im not sure what went wrong. My scale is set to 60, I tried setting it to 120 but that was not correct either. Thank you for any help
