Using Lower Accels While Jogging was created by Beef
Hey, so I'm trying to follow instructions from forum.linuxcnc.org/38-general-linuxcnc-q...n-in-jog-manual-mode with the knowledge that things are a bit outdated there (2015). Using my limited understanding of HAL, the adjustments I made resulted in the following (I have LinuxCNC 2.9 on my machine at the moment)
When looking in HalShow, I have ini.x.max_acceleration (and Y and Z) pins and its current values match what I have written in the INI file. I can also manually set val for it in Halshow. I have placed the above code into a jog.hal file and linked it at the bottom of the other hal files in my main configuration.
However, I get the error
so it's clear that either there's some nuance to how to reference the pin, or I'm missing something about load order where that pin has not yet been created.
loadrt mux2 names=xmux,ymux,zmux
addf xmux servo-thread
addf ymux servo-thread
addf zmux servo-thread
net slowselect <= halui.mode.is-manual
net slowselect => xmux.sel => ymux.sel => zmux.sel
setp xmux.in0 [AXIS_X]MAX_ACCELERATION
setp ymux.in0 [AXIS_Y]MAX_ACCELERATION
setp zmux.in0 [AXIS_Z]MAX_ACCELERATION
setp xmux.in1 1000
setp ymux.in1 1000
setp zmux.in1 1000
net xmux.out => ini.x.max_acceleration
net ymux.out => ini.y.max_acceleration
net zmux.out => ini.z.max_accelerationWhen looking in HalShow, I have ini.x.max_acceleration (and Y and Z) pins and its current values match what I have written in the INI file. I can also manually set val for it in Halshow. I have placed the above code into a jog.hal file and linked it at the bottom of the other hal files in my main configuration.
However, I get the error
./jog.hal:17: Pin 'ini.x.max_acceleration' does not exist
3140so it's clear that either there's some nuance to how to reference the pin, or I'm missing something about load order where that pin has not yet been created.

Two things:
1. Try loading it as POSTGUI_HALFILE
2. Fix your last three lines to this (you are missing a signal name):
net xmux-sig xmux.out => ini.x.max_acceleration
net ymux-sig ymux.out => ini.y.max_acceleration
net zmux-sig zmux.out => ini.z.max_acceleration

Thanks, I'll give it a go.
I think that second part will be the answer. It makes sense as the xmux.out is a pin and not a signal when re-reading the mux2 and net documentation.

Well it works, and it did require both elements. Thanks for the assistance.
I guess it makes sense that it requires postgui since it includes the halui.mode.is-manual element.
For any who come here anyway, the working HAL code is as follows

there is special accel parameters for jogging..
setp joint.0.jog-accel-fraction .2
setp joint.0.jog-accel-fraction .2

Well that's a hell of a lot cleaner. I saw this on the Discord from you and intended to cross-post here for whoever comes with a similar question, but you beat me to it.
Thanks for pointing this out.
