I'm tweaking the post-processor for Vectric Aspire for use on my mini-mill, by default it puts a tool change at the start of each file, I don't really want this.
This is the start of a file...
N240 G00 G21 G17 G90 G40 G49 G80
N250 G71 G91.1
N260 T2 M06
N270 (T2 - 5mm Carbide YG)
N280 G00 G43 Z20.000 H2
N290 S19000 M03
N300 (Toolpath:- Apertures Roughing)
N310 ()
N320 G94
N330 X0.000 Y0.000 F1000.0
When edited I get this...
N240 G00 G21 G17 G90 G40 G49 G80
N250 G71 G91.1
N260 G00 Z20.000
N270 S19000 M03
N280 (Toolpath:- Apertures Roughing)
N290 ()
N300 G94
N310 X0.000 Y0.000 F1000.0
Seems ok to me, I tried running it but the mill started running the file with the spindle off, luckily I e-stopped early enough to stop damage.
I then reset and tried an M03 in the MDI box and I got "Compiler error in M03.m1s" message, could not get spindle to start, rebooted and suspecting the code was wrong I returned the file to it's original state and tried again to get the job done - it worked ok this time.
So, I don't know until i try again if the code change was wrong or it was just some sort of duff boot-up first time round??
