Hello! Please help me in the Gemoccapy Interface to connect gmoccapy. spindle_feedback_bar and gmoccapy.spindle_at_speed_led. How to register in postgui.hal.

there shoudt already be a NET Spindle-at speed
look into the HAL of the mashine
then in postgui simple use this net
net spindle-at-speed gmoccapy.spindle_at_speed_led
if not you can use the pin of the spindle
net led spindle.0.at-speed gmoccapy.spindle_at_speed_led
you can use HAL SHOW to see if you got thise pins alredy connect so you dont run into error

I write "net spindle-vel-cmd => gmoccapy.spindle_feedback_bar" in postgui.hal - and get error "Pin gmoccapy.spindle_feedback_bar doesn't exists". When the Halshow command run, everything works. With gmoccapy.spindle_at_speed_led is similar. How I should register that command? I do not understand how it can work with halcmd, but doesn't work when I put same command in postgui.hal.

Is the postgui.hal file called as a POSTGUI file in the INI, or as an ordinary one?

Thank you so much! I am 66 years old and without knowledge of English was lost in the beaten information. Linux newbie. Thanks again to you and the whole community for your not easy work!

so after years of fighting with computers and parallel ports I have decided to get myself a Mesa 7i96.
I have setup a Raspberry pi 4 with debian 10 and linuxcnc 2.8, but the 7i96 config tool doesn't seem to run under debian 10 I think based on one of John's message in the 7i96 configuration tool thread. I followed John's instructions for installing it but I can't get it to work.
So I have started down the road of creating my own hal and ini files from the 7i90 examples. I seem to have the three stepper motors config working but now I need to get my spindle going.
I'm not quite sure how to port my old spindle configuration over to the new hal and ini format.
I am using a frequency to isolated analog output board to control my spindle controller. In my old config I used a stepgen to control the frequency which would in turn drive and relate to spindle RPM.
I'm not really sure in the new ini and hal configs how to port this over to the new format and to work with the 7i96.
I have a ctrl_type set to velocity.......at the end and p for position control.
how do I define my spindle in the ini and in the hal for this velocity control.......yet using the stepgen for frequency generation?
below is part of my old hal file

Can you give us a pin list for your 7i96?
(just start linuxcnc then open a terminal and type "halcmd show pin *7i96*" , then paste the output here (preferably in code tags)
Things should look pretty much the same as your current setup, except you set the spindle stepgen to velocity mode with a parameter:
linuxcnc.org/docs/2.8/html/man/man9/hostmot2.9.html#stepgen

Hello!
Can anyone share a hole folder with a 3 axis configuration for a LCNC 2.7.15 and MESA 7i96? (Debian 9)
I will try later the 2.8 version. (I'm new in LCNC and there are a lot of changes)
