I have been going thru some engraving practice and notice that I often have an issue w/ the output file having two sets of codes on 1 line. I then need to break that apart manually. Is this a known issue or something I'm not setting up correctly?
V12 CAM, Mach3 post file. Tried multiple fonts. Same result each time.

text to engrave "Ash" .75 x .75 inches Font gothicE NO CHECK on the area clear or inside tick boxes.
Notice the N6 line below. mach3 will push out an error "Cannot use two gcodes that both use Axis values'

( Produced :- 18:09:04 Friday, November 14, 2014 )
( CNC File :- ASH-EngV1 )
( Post Processor :- M_MACH3 )
( Part Number ID :- ASH-EngV1.cnc )
N5G00G20G17G90G40G49G80

N6G00G28Z0.0 -ERROR LINE- CHANGE TO Two lines below:
N6G00
G28Z0.0

N7G49
N8T12M06 ( Ball Nosed End Mill 0.03" Dia )
N9G43Z1.9685H12
N10S1000M03

I really don't know what happened but it started working? I had restarted app a few times and that did not seem to fix it yesterday... so who knows? I was playing w/ the size and setup some and I realized it was working? I did not try other fonts or styles. Wanted to update.

Hello,

It's not anything to do with what fonts or text sized are used.

It's something inside the MACH setup - originally when we first created the post for MACH we had the lowdown on the exact format required from Art. When we produced the post everything was OK for about 2 years and then we started getting reports about this type of thing.

I don't know what to change in MACH but the easies thing is to change your post to output the G codes on separate lines, here is snippet of the before and after changes required.

:SELCTL = {
IF ($USR1 EQ 1) THEN
#N (M09) EOB
ENDIF
SET $USR1 = 1
UNSETALL
set $CYCLETIME = $CYCLETIME + 0.5 ; 30 seconds for a tool change
if ( $Z ne $ZTLOAD ) then
#N (G00) (G28) $ZTLOAD:ZAXIS eob THIS IS THE LINE TO CHANGE
#N (G49) EOB
endif
#N (G49) eob
#N $TOOLNO:TOOL (M06) " ( " $JOBTEXT " )" eob
#N (G00) (G43) $CLEARP:ZAXIS $TLCNO:TLC eob }

Change to .................................................. .................................................. ........

if ( $Z ne $ZTLOAD ) then
#N (G00) EOB
#N (G28) $ZTLOAD:ZAXIS eob
#N (G49) EOB

This will split the output into two lines with an EOB - End Of Block character between each line

Hope this helps.
