A 1000,000 ns (1 ms) servo-thread period is standard
A 100,000 ns (100 us) servo-thread is going to be too fast for most hardware

I would not use pncconf again once you have the basics setup

To invert the stepgen direction, you can for example:

setp hm2_7i95.0.stepgen.00.direction.invert_output true

Great i will try it out.
I have to say i'm very impressed about the mesa card and linuxcnc.
I've been thinking about rebuilding this machine for many years.
I can't believe it's moving again without that many issues.
Great support!
Thank you @PCW

Hello everyone,

I tried to configure my endstops as recommended a few post earlier.
It looks like i'm not using the right parameters to get this working.
I used the command exactly as you told me to do.
Attached you can find a photo from the error showing.
Thanks to you all!

That's odd, if you load LinuxCNC and run this command in a terminal window

halcmd show all hm2_7i95

what do you get?

Also are you running LinucCNC master? (2.9)

When i use the suggested command i see an output list of all my i/o ( good to know).
I changed my I/O names to hm2_7i95.0.gpio.000.in Now i can boot linuxCNC without any problems.
As soon as i start to jog an axle the following error show up
When i push home all it starts to home the Z axis( but very very very slow, where can i change this in the .ini file?)
The moment my Z axis reached it's inductive sensor( active high led on the correct input on the mesa card lit up) my Z axis kept on moving towards the endstop until it hit the hard stop.
So my endstops or I/O are nog coming trough into linuxCNC.
What can i do about this?
Do you need a printscreen from the halcmd show all command?

You cannot use GPIO for that application, all isolated I/O on the 7I95
uses the inm module

Please do not use printscreen or screen photos
but rather post a copy of the file to the forum

To make a file of all 7i95 hardware pins, you would

halcmd show pin hm2 > 7i95pins.txt

and post 7i95pins.txt here

It would also help to post your current hal and ini files
