Hello, I am Diego, this is my firt post.
I am testing BobCAD with Mach3 plasma profile on a oxygen torch cutting table. I installed postprocessor "Mach_3_Plasma_Metric_Rev1.MillPst" from BobCAD web site. BobCAD is v24 and setting as plasma machine.
My output 1 is a reley for oxygen electrovalve. Works ok, i test writeing M03 and M05.
The problem is the gcode. when it should turn ON or OFF the reley the gcode set M05 ... always.
What i am doig wrong ? how can i set mach3 for turn ON and OFF the reley ?
Other problem. With postprocessor "Mach_3_Plasma_Metric_Rev1.MillPst" gcode has not FEEDRATE parameters ... no matter what feedrate set for plasma. But it works well with the "Mach_3_Mill_No_ATC_Metric_Rev2.MillPst"
I need help please!
Thanks.
Diego

Your problem is with BOBCAD writing junky POST processors. It is not a MACh3 problem call BOBCAD and complain to them.

thanks mr BR549.
but Really ? Please I need real help.
I mean nobody has similar problems?
If this is true then nobody can use bobcad with Mach3.
All i need is some way to turn on/off a reley when gcode set M05. There is NO way to do that?
thank's

In mach 3 you can setup M3/4/5/7/8/9 to active deactivate relays. BUT if your POST is not written correctly NOTHING is going to work correctly as the PROPER calls to the Mcodes will NOT be made. Same with Feedrates.

OK, great!
so, how can setup M05 in mach 3 to active/deactive a relay ?
Thank you.
ps: sorry for my english, it's the best google translate can do :)

From the main screen, goto config, then ports and pins and there look at the lefthand side you will see where to setup the pins for the M3/4 and the M7/8 macros.
i suggest to download the Mach3 MANUAL as the best guide to setting up MACH3.

Thanks BR549.
I have not problem with M3/4/7/8 .... my problem always was M5.
The Manual say M5 is to spindle off. nothing abaut setup M5 to active/deactive a relay.
Thanks anyway.

The M5 and M9 just turn OFF the relays for M3/4 and M7/8. they are NOT assigned a relay option. SO what ever pins you assign they just turn them OFF.

I think we have not understood properly.
The following is the g-code generated using BobCAD using the PP "Mach_3_Plasma_Metric_Rev1.MillPst".

does not appear M3/4/7/8 ... only M05
I need the PP set M03 to begin work and M05 to finalize.
Got that?
I tried all PP for Mach3.
Thanks

AGAIN I say that your GCODE PROBLEM is with BOBCAM writting BAD Gcode. In the post it should turn ON(M3) /OFF(M5) the torch as needed. OBVIOUSLY it is NOT writting the correct Gcode to do so.
To add to that the code you showed is some of the WORSE plasma cutting Gcode I have seen produced from a CAM package. NO ONE uses SUBs to cut with a plasma machine that I have ever seen.
It is NOT a mach3 problem.

Hello, sorry for the delay :(
ok, i agree. The problem is with BobCAD.
Can anyone recommend any CAM for plasma cutting? Preferably free
Thanks !!

SheetCAM
I think the first 180 lines are free.
The $ aint bad anyway for the full deal.
GREAT support too !

Seeing that you already have a copy of BobCAD CAM V24, there really is not need to purchase other software. You'll find that making changes to the post is easy enough to do yourself, but if you would like me to help I can.
Yes I would turn subs off, and yes the post processor can be setup to fire any m code you want at the start of cutting and at the end of cutting. If you want to use a dwell you can do that aswell.

I can email you the post, and make any other changes you might need. Just call me and I'll take care of you.

I didn't get a call or response so I guess you are up and running? If there is anything I can help with please let me know.

it seems that you do not have the post processor loaded in your cam system. I faced this before and being supported by bob cad cam.com they helped me to set the post processor in my bob cam where every thing works well

Can anyone recommend any CAM for plasma cutting? Preferably free
Free I don't know of.
A friend is using Lazycam ( you need the pro version for Plasma) and the gode generated is good based on the required plasma inputs. You would need to set and use the plasma parameters in Options and need a workable script for the M code used.
FWIW,
