Help with esp32? was created by OneMyr
Hello there
I was looking for a way to run Linux cnc with a esp32 working as a step generator like i saw in a fórum with jzolee work. But when i finished installing and doing The halcompile, when i tried to run The Program, this is What i got
drive.google.com/file/d/1Lx-7ENpbt4-lK1O...sy/view?usp=drivesdk
This erro shows before The Program status, and
drive.google.com/file/d/1L_EdgUyE28wN9fU...AD/view?usp=drivesdk
The Axis was in a strange position and i Just can't press The Estop Button.
I really don't know How to fix this, maybe i am kinda dumb, but cant anyone give a little help.
Thanks, and Sorry for taking yout time

This looks like an unusually self-explanatory error message. I commend the programmer 
Maybe this will help you decipher what it is trying to tell you?
linuxcnc.org/docs/html/config/ini-config...sub:ini:sec:rs274ngc

This looks like a HAL configuration problem. Something is triggering the E-stop. Can you attach the HAL and INI files from your config?

I think that the problem is somewhere in these lines:
Normally there is a very short loop:
Yours is set up to additionally depend on the "udp.ready" pin going true.
You can check if it does with the "halmeter" tool, available from the "machine" menu in the axis gui, other places in other guis, or with the command "halcmd loadusr halmeter" at the command line. You can load as many as you need to watch multiple pins. Or use "halshow" to "watch" multiple pins.
However, I also noticed:
Which is unusual. In fact I just tried loading an extra thread after loading emcmot and it caused a segfault.
As your udp-thread is the same speed as your servo thread, try removing the udp-thread. (remove or comment-out the loadrt thread.... line) and add the udp component to the servo thread:
loadrt and2 names=no-estop
...
addf no-estop servo-thread
...
net no-estop-a iocontrol.0.user-enable-out no-estop.in0
net no-estop-b udp.ready no-estop.in1
net no-estop-out no-estop.out iocontrol.0.emc-enable-inNormally there is a very short loop:
net e-stop-loop iocontrol.0.user-enable-out iocontrol.0.emc-enable-inYours is set up to additionally depend on the "udp.ready" pin going true.

Looks like a typo. "0setp" should probably be "setp"

Okay thanks again, it wasnt just this, but after a few tries i managed to turn the machine on, but when i try to move one of the axis, the program shows an error like in the image
yeah i know the error is in portuguese, but it says "axis movement calculation error"
and it repeat for every axis
