NOOB with a gcode question...?
« on: February 05, 2021, 01:05:28 AM »
So I am slowly wrapping my head 63 year-old head around Mach3 and gcode... but I have had something come up that I don't understand...

I was modeling a little plaque with some text to v-carve on my cnc router and get this gcode (it's 8000 lines- I won't paste the whole code!)
My questions are this: Line 14 is requesting tool #10- no problem. But when I re-choose "start" nothing happens... why?

So, I configured Mach3 to ignore tool changes, and it went past line N14, but hung up on N16... and there it's stuck.

So- why did it stick on N14, then why did it stick on N16?  Also, I chose "Mach3 ARCS inches" as my post processor- I didn't chose "Mach3 ATC" so why is it hanging at line N14 like its waiting for a tool change?

Is this a Vectric issue, or a Mach3 issue?

Help!!

Thanks for your time!

if you are not working with toolchange and tool length compensation you can delete line N140 and N160 completly.
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

Great!  Thanks!  But... is there a simple explanation as to why they are even there?  Did Mach3 put them there, or did Vectric?

Vectric did.

N140 is the code to initiate toolchange
N160 is the code to activate tool length compensation
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

Thanks so much.  I'll check my Vectric settings to try to fix these...
Thanks again!

You should choose a post processor which does not generate ATC code, from top of my head Mach2/3_arc_mm or Mach2/3_arc_inch (I'm not near the computer that I have Aspire on)
Make no mistake between my personality and my attitude.

My attitude depends on who you are.

Thanks @ZASto-

But that brings up another quandary-

That code was generated by exactly what you mentioned-  "Mach3 arcs inches"  so I don't know how the tool change command got in there...

Well, I guess that there are some lines in the post processor that should be removed.
put this modified post processor in your %programdata%/vectric/..../PostP (or My_PostP) folder.
I commented the offending/un necessary lines.
