Sometimes you need to know where to looks in the docs. how to set a pin value from the ini file
linuxcnc.org/docs/html/config/ini-config.html#sub:ini:custom

qtdragon has a facing option built in. Why not use that?

OK, yank an LED from anything you have no use for, stick one pin of that LED in hole number 2 or 4 and the other pin touch the metal shield on the parallel port, now jog LinuxCNC with the keyboard and watch the LED light up ... dimly, set a faster feed rate and it will glow a bit more.
Yeah, make a simple config before doing that and start LinuxCNC so you have something to jog..
Or use the config picker by starting LinuxCNC from the menu and chose sample configurations> by_interface>parport>stepper>mm or inches

Thought I'd chime in, there's also the option of a CPU upgrade, did wonders for the ThinkCentre I found in the gutter.

thanks,   it does seem to be ok.    it will be a bit before i actually have some hardware to connect.    but i have been able to move the tool head around and PLAY the original linuxCnc gcode that traces LinuxCnc on the screen and the jog buttons are working.    

i will catch up when i get some hardware,   hopefully  within a couple of weeks.   I wanted to start with a technic clearpath all in one servo, for the quill

have a good night, and thanks

I might not be the "best" to answer this, but since i see you're head first into self destruction, leme help :
-QtDragon does not care about your spoil board, nor does FreeCAD
-... i am out ...
Back on topic, i can not recall what i used some 15 or more years back for that exact purpose, but i am sure it was free and Open Source, but:
forum.linuxcnc.org/20-g-code/42707-g-code-generators
wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple...NC_G-Code_Generators
And most probably this will do just fine
github.com/LinuxCNC/simple-gcode-generators/tree/master/face
and the bunch here
github.com/LinuxCNC/simple-gcode-generators?tab=readme-ov-file

For the life of me, I can not find ANY useful info on how to re-face my spoilboard. Sure, I would have to buy hundreds of dollars to get a program to do what Qtdragon should be able to do with out that. I have FreeCAD but, I also seems to not have the means to do this. Is there any one here that knows how to make a G-code operated machine simply go back and forth at a set high across a set dimension?
As you guys will have questions, I will be glade to answer to get this spoilboard faced. before I burn it to the ground.

Looks fine so far, move on!
There should be no issues with the BOB as long as your servo drives can accept step/dir control signals, or even quadrature or UP/DOWN.

thanks again for the help     this is what i have set up NOW,   exercised latency is as pictured,

Are there any Known problems with a C11G multifunction CNC board?    for AC servos?

thanks

i have disabled all the options in the above picture . the latency test is still early, but it looks much much better

OOPs   i read a snippet from somewhere that said it would be good to start on a single core and the add the cores if i need them?     

i disabled the C1E, but not the C1,   i did not see C1 as De-selectable,   I will try again 

i can change it back correct?

OK C state support is set to C1.

and multi core is RE-enabled

thanks very much for your help PCW.

i am re running latency test again,   i did not take a pick from a few minutes ago,  but i think the servo thread was under 10000, and the base thread was about 26000

 

yes, you want multicore processing enabled

You should also disable Cstates > C1
 

After a bit of luck i have managed to access a menu that has the hyper threading setting.   In the pic  i have disabled the top 2 options.    How about the rest of the settings in this menu? 

  DO i need multi core processing??

Are these changes permanent or do I have to resett them every time i power cycle?

also i am double spacing these posts when i type, but when i submit the post ;   they get all squashed together.Is there a way to keep my double spacing so the post is easier to read? 

Thanks rodw,

I've added the following to my .ini file:

[LASER]
laser-offset-x = -3.2017
laser-offset-y = -0.2124

I've tried several ways that I could think of to reference these values in the gvcp-panel.ui, as CALL parameters to the EMC_Action_MDI widget without success.  I've also tried to just reference them in the auto-xy-zero.ngc file called by the EMC_Action_MDI widget without success.

A review of the online documentation has not been helpful either.

What is the correct method to pass them to the ngc file for execution?

Kind regards,

Hi, after a couple of months I'm back on my Brother TC201 retrofit, Will post pictures soon. As a newbie with probe basic (and LCNC) I did my best to configure it but without luck, I guess I'm missing a big chunk of knowledge somewhere but cant figure out. here is my config, actually the ATC tab look like in the screenshot. Please point me somewhere

Another thing I noticed is that when looking at the circuit diagram the +24 volt input is not connected to anything, the same on the PCB this pin is not connected either, only -24 volts is connected to the current limiting resistors at the inputs of the optocouplers of the inputs.
