Thanks for reviewing my HAL file. So I learned that there is no "motion" component. Instead, it is the "motmod" component I should be trying to load.

My bigger mistake was trying to code a HAL file by hand from scratch. I learned that I can use LinuxCNC to create a configuration which generates the ".ini" and ".hal" files. And then I can modify those if they require any other changes.

Like I said in my earlier post, I'm just learning LinuxCNC now. And on top of that, I'm trying to understand HAL, and what Mesa cards I need to buy, and what components I need for the lathe CNC conversion. I am drinking from a fire hose!

Thanks again for your help!

Take a deep breath, remain calm and read the stepper motor stuff by gecko

This one is rather enlightening regard power draw and such

I've had my mill setup for that long, using KL5066 drivers (no longer available) max PSU is 50v and I've been running them for years, 10+, on 48v with no ill affects. I think the motors are set for 4 or maybe 4.5 amp I thought I'd add I've run them on days where its been +35'C outside no idea what it's been in the workshop.....no issues

@meister Thanks for the offer, but I think I have it figured out, just waiting for the board to arrive and test!

 
 

Thank you for considering my suggestion.

It's true that the 7I76U P1 DB25 pins are not relevant to normal
LinuxCNC setup which deals  with things like stepgen numbers.

The picture on page 4 gives the general location of the I/O pins and the individual
connector (TB1 through TB6) tables give the details. I guess it would be possible
to have another drawing with the individual pins labeled.
