It would be helpful if you included the reported error here.

I get several errors:

there seems to be an error in your hostmod configuration

no tool table file

no shutdown.hal file

pid does not have a name option

your have pyvcp pin in the main hal and they are not created until the GUI is finished loading. Any reference to a pyvcp pin must be done in the postgui.hal file.

This config will run on my 5i20 machine. Note all the things I commented out and the changed hostmot config line.

thanks for all your help john i will have to look tomorrow when i can get to the shopw

hi again guys the machine has been running like a champ with various little tweaks here and there

one thing that i do want to change is currently i use o words to start and stop the torch ( it runs the hight control timing pierce delay and such)

and it just calls for a digi output to be turned on and waits for its arc ok on an other digi input - currently works fine

the issue ive found is that very now and then for some reason the hight control has just drifted up away form the plate (mainly due to a buildup around the sensing ring and cables - capacitive hight control)

im in the process of building a new height control axis for this machine that will be voltage controlled

for now im wanting to have it so if the arc stops for any reason the machine will pause and for some reason im thinking ive read somewhere that if i wire the arc ok signal to the spindle is at speed pin that it will pause motion if this signal is lost ?

if this is so am i right in thinking that in my o words i can swap the g64 and g65's for m5's and m3's ?

also on a side note how do i pass a variable from an on screen spin box to a o word ? as in setting pierce delay ether from software or the on screen spin box and is it possible to have the spinbox be set buy the gcode (asin if the sofeware will spit out the delay this will then change the value on screen in the spinbox and then as the program is running if the delay is too much or not enough it can be changed while the program is running ( i know this will not change the value till the next arc fire)

thanks guys

I don't think so. It will wait until spindle-ar-speed is true before starting motion, but I don't think it stops motion if it goes false.
You could use motion.feed-inhibit to stop motion, or if you want a more obvious effect you could drive motion.enable false

The latter would take a bit of cleverness to allow motion to start in the first place, though.

Yes, and in fact you _could_ consider, with the latest LinuxCNC, making M3 and M5 into g-code subs with the "remap" feature.

also on a side note how do i pass a variable from an on screen spin box to a o word ?

If it is read in a G-code, then use the analogue inputs (M66). If you want it in a bash scrip then halcmd getp pyvcp.pin-name should work.
