ONE last word of warning, MACH3 has a NASTY safety BUG in CB macros. IF the Macro is in the middle of a loop controlling motion AND you ESTOP then clear the problem then RESET mach will resume and  RUN the motion loop stored in CB.

When in Estop ALL macro threads "should" be closed/cancelled BUT they are not. (;-)

Just a thought, (;-) TP

Russ ALL mach3 axis are tied together for the FRO. The Spindle function cannot drive an axis.

Mach3's Gcode does NOT have an interupt as per say.  IT can only follow where the G code takes it. Being it does NOT do conditional it is very limited for general Motion control operations.

The way I see it would have to run (dependably) Is the operator inputs the length of part and Material. The Program then calculates all the parameters such as Cycles per section and sections per material length then UPDATES the Gocde Vars that drive the MOVE then Cut G code loop.

That way G code controls the Motion NOT CB and there would be few if any problems.

Normally Mach3 makes a POOR PLC as there is no easy way to control the CB threads to keep them in time sync. AND you cannot control an axis directly through CB it has to Move OUT to a G code function thread  to be able to move an axis.

You may be able to pull it off with a PLUGIN but that is another story.

Atcually that is what I do build it into the screenset. BUT then I cannot give you MY screenset to use for a cool function.

Wizards make that easy as they come self contained OR so I thought (;-( and made it easy to share functions.

But all that is now useless in most cases as there is NO provision to detect shared DRO,LED,Userlabels across Mach3 or all it's possible wizards and Macropumps and brains.

OH well , (;-) TP

SORRY but mach3 does NOT have conditional Gcode.

Mach3 does not always abide by the input Msec loop values (;-) .

Been there done that , (;-) TP

Arts notes:
Systemically, they are global, BUT when you load an addon, they are saved, the
addons values are loaded, then when you exit an addon,
they save to the addon, and reload the globals that were in effect at addon load
time. SO each should not affect the other.
You can see some strange effects if you load a wizard from a wizard, as that
could scramble things up a bit. Ill schedule that for a check,
but this was refined with an OEM with many special screens abotu 2 months ago,
all reports are good on that now. It was somethign not
noticed by general use, it took a special circumstance to see it..

Thanks,
Art

BUT that appears to be NOT the CASE  in MACh3. As it has either changed or is broken.  What a mess it makes with wizards especially with MACROPUMPS running in the background.

I found some old trouble notes from MANY years ago stating the same thing so it never was FIxed correctly.

OH well, (;-) TP

I rememebr Art telling me that wizards were special and had their own def file stored in the wizard directory that held the Dro,led values to be use ONLY with that wizard when it was called.

Wizards would be basically useless with people from all over adding to the general mess IF all of them drew from the Dro global pool.  HOw would everyone keep track of the useage???

Seems it could be true though,  So much for doing anymore Wizards

General Mach Discussion / DRO#s in WIZARDS
« on: June 23, 2012, 05:22:43 PM »
I thought that ALL dros in Wizards are treated independantly in MACH3 . IF you had a UserDro(2000) in one wizard it would NOT effect the same use of the DRO in another wizard or MACH3.

BUT that does not seem to be the case any more. I have wizards that are updating each other from using the same DRO#s.

Anyone else seen that lately ???

I think NOW I remember WHY I stopped building WIZARDS LONG ago,  :'(  >:(

Just when you think you have it figured out AGAIN, (;-) TP
