Raspberry Pi 4 with Mesa 7c81

Thank you so much. I have made the changes. Last question... is it necessary to change all instances of 5l25 in these files to 7c81 or just the two instances that you mentioned?

There should only be one instance of "5i25" and it should be in the .ini file.

This is using the latest version of pncconf and there is a feature for having the
card name as a substitution (alias) from the .ini file:

Reading through the Hal file there were several instances. Ex:

setp hm2_5i25.0.Stephen.04.dirsetup

I did not check the use ini substitution box in pncconf. Should I go back through and do that?

Or alternatively make all the changes in the Hal and ini files?

Thank you. This has been such a process and learning experience. Can’t wait to finally turn on the machine!

*correction. Example should have read

setp hm2_5i25.0.stepgen.04.dirsetup

You can do it either way, I prefer the substitution way
rather than doing a global find/replace

Huge thank you to PCW and andypugh! I have a functional cnc router! So grateful for the knowledge, quick responses and this forum.
