General Mach Discussion / Re: M7 and M9 controls

Normally one uses the M3-M5 to turn on/off the torch and use the M7/8 M9 for options.

The M9 should NOT be shutting down the torch UNLESS you have duplicate pins set.

You would set your MAX rapid speed in MACH3 config motor tuning.

You would set the Rapid (travel) Height in Sheetcam.

It's just hot blonde and sweet with a little extra coolant mixed in.    


Even slower with CV bascially off the cut is a bit rough on the corners and seems to be squirly on the staright cuts BUT that might be the pictures.

It looks as thought the cut height may be too high and the arc is not stable. What are the cut paramaters? Material ?pierc ,cut preset voltage,etc

Are you running with the DTHC active ?  It it maintaining voltage?

General Mach Discussion / Re: G92 and G52 - How SHOULD They Work?

« on: January 30, 2012, 08:18:57 PM »

BY the manual I have it backwards G52 is local and G92 is global, G92 actually reset internal parameters when in use. It warns NOT to use the legacy G92 when other offsets are applied. And it advices not to use both G52 and G92 at the same time.

I can tell you for sure with G92 in effect strange things happen form time to time whether it is MACH3 or self inflicted they do happen(;-)

Sticking with G52 and G10 was very stable

I 'd have to look up the Fanuc version again to be sure.

Just a thought, (;-) TP

We may all be confused.  G92 shouldl offset the part in the current fixture(SayG54). AND I believe the G52 SHOULD offset ALL the fixtures as well.

But I remember the MACH3 manual WARNS that is is NOT a good idea to do both at the same time.

Mach3 does NOT always follow the Fanuc conventions (;-)

Might be time to TEST both to be sure.

Look at the posted code. The re is ONLY one operation listed in all the code and that is an OUTSIDE cut.

That tells me that when you cammed it out in Scam you did NOT set up a layer and operation for the inside cut but used the outside offset process to do everything.

So it really did NOT cut where you thought it would.

It would treat an outside cut differently from and inside, MAYBE

Just a thought, (;-) TP

I guess yall missed the part where he used an outside offset for and inside cut? That CAN throw a monkey wrench in the way Scam sees and programs a cut.

We use a similar size table and hardware electronics and DO NOT see this problem here.
