The encoder wires to the DRIVE.  Mach3 does not close the loop it is closed in the drive.

HIYA Ray, What version are you running IF V.066 then you may want to DUMP that version and back up to .062  .  

as to isactive() sometimes

true / false works sometimes NOT

is /not may or may not work

-1/1 may or may not work

0/1 may or may not work

sometime the signal inverts sometimes not

SLEEP() (;-) anything under (10) is useless and don't count on it being exact cause it may or may not be.

It just depends (;-)

(;-) TP

First you feedhold till motion stops then STOP. Write down the numbers of XY. When restarted AND IF you have not moved the table. Just input teh X values in the DRO and press enter then do the Y dro and press enter. THEN you are ready to go.  NOTE the table may not be exactly to the exact  step at the correct location but should be very close within a step or so.

I had to dig WAY back in the OLD notebook for this one(;-). In theory yes you can look at DRO(19)  (GcodeMode) and IF = 1,2or3 then DO a TOM routine and then fire the torch (DospinCW) . AND if Dro(19) = 0 then DoSpinStop() (shut off torch),  IN THEORY. THe problem is in real life MAch3 does not update that dro reliably and MOST times it never changes state. It will in single block mode running 1 line at a time but NOT in run mode processing 1000's of blocks. 

SO you loose control over the process.

NEXT problem the Torchmate files DO NOT have any Z axis motion code in them. That part was handled by the Torchmate Z controller based on THC values and Homed to Z  when the torch was off. You could do some fancy code in the M5 macro to send the torch up to the Zhome (Top of stroke) every time it turns off or to a safe Z value POSITION + SafeZ incremental.

BUT you still have the dro update problem. AS that info was NEVER important to users of Mill/router/Turn that update has a very LOW priority and updates when it has time (maybe) I have seen it run 100s of lines of code and never update.

NOW the answer for them is not in hardware but in Cam software. If I remember correctly it IS possible in SheetCam to do an auto import/export Plugin that can convert a BATCH of files to the Mach3 plasma post of choice.  THEN you NEVER have to worry about MAch3 failing a script again.

The COM signal loss would have been an easy fix.  Currently there is NO plugin to do it that I am aware of.

Send me a short test file from the TM so I can test something.

YA should have thought about that before you converted it.   :o

  Many people have ran into that problem when wanting to convert a Torchmate machine.

There is NO easy way to do it short of a PLUGIN written to do that function.
Are you now using a Z axis and floating head to find the TOM (top of material) ?

General Mach Discussion / Re: Unequal Backlash
« on: July 12, 2015, 03:37:24 PM »
Mechanical backlash will be equal in both directions. This sounds like backlash PLUS a loss of steps in one direction only. That could be DRIVE related or a mechanical problem.

Just a thought, (;-) TP

The BEST approach would be to be PCI or PCIe motion card. Eliminate the Eithernet/usb bottleneck control problem.  Tormach has the right idea eliminate the problem to begin with then you do not have to deal with it anymore. There was a reason PC monitors never went USB or eithernet and it should apply to Motion controllers as well.

AND yes Some modern CNCs do run eithernet BUT they also have 2-4 main CPUS to keep it all running together and in sync. We basically have 1.
