Maho MH800e Retrofit Project was created by Cooped-Up
I have recently set out (over a year ago) to retrofit my mh800e with linux cnc to make it more user friendly and capable. I had some hurdles with confusion on the mesa cards I am using but I was finally able to make some headway and now have control over the outputs. now I am trying to figure out the mh400e_gearbox program that rotary smp was involved with. if I can figure that out I think I will have a fully functional machine! after I wire everything that is...
here is my debug information

When LinuxCNC added the feature to support multiple spindles, the spindle pin names changed.
for example:
motion.spindle-speed-in
becomes
spindle.0.speed-in
for example:
motion.spindle-speed-in
becomes
spindle.0.speed-in

Noted, that was easy enough to change. I noticed my config had said joint in many places over the word axis. was I wrong to change it all to say axis? new debug text

I deleted my reply, twice, as i can not fathom why...
It is a huge machine with several hundreds of KG of moving mass that can easily break you like a twig, yet you allow yourself to change things you do not understand that will ultimately be controlling that machine!!!
Read, ask, do NOT assume.

Yes, you are wrong, as proven by the error, AXIS_0 P does not exist, but JOINT_0 P should.was I wrong to change it all to say axis?

copy that, I changed it on the premise that the hal file I am referencing has the axis part and that was the only difference. I thought I screwed something up in the config as I recall something about selecting joints over axis. I will change this back. sometimes I overthink thing, with the speed at which you respond I am much better to just ask haha. feel free at any point to call me an idiot, I dont mind

okay all the axis are now back to joints. well I changed the ones i copied to joints as they were originally just axis. now I am having this error I am looking into

is the solution replacing with halui.joint.0.minus? I found that in some research but dont want to do anything rash quite yet...

Can we start over?
Upload the hal and ini files here so we can have a look.
Also important as it seems, was this config made before LinuxCNC 2.7 or thereabouts?
What version of LinuxCNC do you have running now?
What Mesa cards are in use?
