What version of Flashcut are you running ? IF it does the job why update??

You cannot run MACh3 with the FLASHCUT control box. They are NOT compatible.

You would have to strip out the motion control electronics in the Flashcut box and wire directly to their drivers.

IF it were me I would run the Flashcut system until it died.

Just a thought, (;-) TP

IF the Mach3 too lpath is showing the mirrored image then your Gcode is mirrored. IF the display is correct and it cuts mirrored then the motor is backwards.

The lead in / out  is ONLY there to give MACH3 room to do the tool radius comp move. IT is up to YOU to make sure the profile is fully cut(;-) as part of your programming in Gcode.

You may want to try it this way. I am assuming that you have Home offsets in place to indicate where you want Machine 0,0,0 to be with the G28 function

DoButton( 24 )
While Ismoving()
Wend
DoButton( 23 )
While IsMoving()
Wend
DoButton( 22 )
While Ismoving()
Wend

Code" G28 "
While Ismoving()
Wend

Code"G92 X0 Y0 Z0"  'Sets user X0Y0Z0

Like I said above MACH3 does NOT have conditional Gcode. Some people have just found ways around that problem in their OWN way.

So there really is NO "documented" way to do it.

actually you need to read the manual(;-)

G90 set abs motion
G91 set inc motion

G90.1 set abs IJ arcs
G91.1 set inc IJ arcs

The Gen config setts are just the defaults that Mach3 starts up with.

To use Cutter Comp you still program as tool centerline and you use the Comp to offset the toolpath by the value of the tool radius. BUT you have to use a leadin/out to bring the tool into play or out of play for the moves.

Best get a GOOD gcode manual to study as describing it in full here could take HOURS of typing(;-) Also note that MACH3 may have nuaisences that other favors of Gcode do not. So the basic's apply but the fine tuning may be MACH3 specicfic. Should be covered in the manual(;-).

Arcs, IJ mode? you can have it either way it is covered in the manual

Not a great idea to "try "and use the toolcomp offset to do your machining that way. Just program the moves as you need them. Go down the line move over a step over amount and go back to the beginning, Repeat until you are at the final value.

Just a thought(;-) TP

The M1000 code should read
