Mach3 XML and Stepconfig issues.

Mach3 runs OK but I cannot get LCNC running, the Charge Pump will not work as expected.

Can toggle F1/F2 but no power via Charge Pump.


Can anybody see what is going on here?
I know that spindle will not work as is ( now Step/Dir controlled ) but I want to get other functions to work before
I change out my old BoB tyo a more modern with PWM for spindle 0-10V for the VFD.

Need to have both Mach3 and LCNC working on same setup PC/BoB.
Provisions for pin 13 coming for ChA from encoder.

Most grateful if somebody can take a look and see what can be done.

Cheers

I'm only asking this because you did not say that you tried it.

Did you try to using Stepconfig to import your Mach3 XML file to build your Linuxcnc config file?

What were the results? What are the error messages your getting? Sow us the resulting config files.

I'm not sure that Linuxcnc can't run the spindle the way you are with Mach3, It just might not be the most efficient.

Hi Todd,

Yes imported xml, only X/Z ports where automagic and the rest manually set.
No error messages, only not functional that is F2 will not open Charge Pump (CP).

When starting LCNC the CP temporarily opens and lathe electronics is with power and second after goes off.

Spindle now is OK with Mach and must be changed to work with LCNC = new BoB will solve this.
This Mach setup is from the early 90´s and has been working OK, even with threading.
I was one of the testers for Art Fennerty back in the days testing threading iterations.

What files do you want to see? Can fix this during the day.

The .ini file and any .hal files.

I'm affraid I just don't understand why however Mach is controling your spindle could not be replicated by Linuxcnc. (but I really don't know anything about Mach.) If it is just step/dir signals from the parallel port, that sounds simple and easily doable.
What do you know about how your charge pump works or should work? Lets see if we can figure out why it isn't working.

Will copy files later today.

S/D signals goes via small board that converts it to control the VFD. Sorry to say but I can not find the schematics so I will try to have a look at the board and redraw schematics.

Cheers

Here files as requested.




Hope this helps
