1-is it the way that i underastant line is running the G0,G1,G2 or G3? )it s important for contrloing the electronic check valve.)
2-when  i use the revers run most of the time have error and the machine goes wrong way, more time when i use G2 and G3. i want know it is the software bug? and in the new version have still this bug or no.

helo
i need help please.
any one is here?

Hi Bornaabzar,

Could you attach a typical GCode file that causes problems please.

 and for my first question i use this software for flame cut machine. i want control my flame cut check valve and i need to control on and off the flame. i use on and off spindle function but when i push the start cycle  my flame goes on but i don't want this. i just want when my machine ready for G1 or G2 or G3 it s turn on the flame.
thank you
Bornaabzar

Hi Bornaabzar,

I think I understand your problem.

Although your GCode runs fine here and the M03 / M05 commands operate correctly - they will, however, not operate correctly during reverse run.
(I have only tried your GCode with version R3.043.066 and perhaps earlier versions of Mach3 may behave differently).

Do you have your machine configured correctly so that M03 turns on the flame and M05 turns it off ?

Tweakie.

Reverse run was fixed some time after 43.22. ('twas yours truly that asked B to fix it).

Prior to that on arcs it worked once first time but thereafter it wandered off and did a mirror image of the arc. That said AFAIK it didn't and still doesn't fire macros but I'm not sure it makes sense to do so.

Cheers

Ian

Hi Tweakie
Yes. i use correctly M03 and M05.
in revers run we can turn off the valve by VC scrip program, but after that when i  use cycle start, because i don't know the command line is G0 or G1, i can't have idea for On or OFF valve . because if it was G0 the  valve must be off and Otherwise be on.
thank you 

Thank you IAN
do you mean, in the revers run By G02 and G03 code the machin dont move on main line ? because i have this problem.
thank you

What version of Mach3 are you using?

Ian

Dear Ian
i use version 3.043.034.for my machine.
