Mach4 General Discussion / Re: pmc -parallel line how to do?

« on: June 18, 2021, 02:52:52 AM »

You can place your cursor to the left, right, or underneath most object to insert other objects.  So to do a parallel op, place the cursor under the existing coil and insert another coil.

Mach4 Plugins / Re: XHC WB04 plugin

Ah...  Ok, I wasn't really sure what all the Mach3 plugin did.  You are talking a velocity jog, right?  As in not a step per detent thing?  If so, do you jog by moving the hand wheel dial?  Where as long as you are turning the dial one way, the machine will jog in that direction.  Try to be as specific as you can explaining what it does and I will see what I can do.

I'm not sure I get what you are referring to.  Full speed control of what?  Feed rate override?  Spindle Override?  That is what that speed controls.  The rate at which feed and spindle override increase/decrease with each button press.

You will not see anything in the Mach diagnostic screen if using the PMC.  There is a test mode in the PMC for diagnostics.  The type of device you use for inputs and outputs doesn't matter.  Pokeys, PLC, MODBUS, etc...  all will work with the PMC.  The test here is if it functionally works and does what you want.  Then having lights lit up in the diagnostic screen of Mach is useless.  However, you could add a rung on your PMC ladder program to raise/lower a Mach signal so that you could see it on the diagnostic screen.

Yes, if the part being cut has many cuts or obstacles instead of one long single cut.  Basically, the machine SHOULD operate as per the simulation in sheetcam.

Your conclusions look good with the exception that I think the sheetcam simulation is correct.  That is what is is supposed to do.  However, what sheetcam is writing out for G code is NOT correct, at least for the plasma post.  So I would most definitely take a look at the plasma post processor first.  The task of a post processor is to make G code (for s specific machine) that does EXACTLY what the simulation does.

Mach4 General Discussion / Re: Mach4 Post Processor for Plasma in Fusion 360 and a ESS motion - Cant Find One

How about this one liner?  In the original post code, change:

writeBlock(mFormat.format(power ? 5: 3));

to:

writeBlock(mFormat.format(power ? 62: 63), "P3");

Or I think

writeBlock(mFormat.format(power ? 62: 63)+"P3");

will work too.

Also, the PMC can do stuff like that VERY easily.

Ok, you are in luck because the very guy that designs and builds the MB3 also figured out how to make the MB3 (and other breakouts as well that have had issues with that VFD) work with that Haunyang VFD.  https://www.youtube.com/watch?v=jgZ8UbcowLQ

The PMC doesn't require the I/O to Signal mapping.  But it can, in effect, map an I/O to a Signal.  You can make a ladder "rung" that will effectively "map" a discrete device input to a Mach input signal.  Or map a Mach output Signal to a discrete device output.  The PMC is VERY flexible. 

For inputs, yes, the PMC can use a device input and that very same input can be mapped to a Mach signal and used in the LUA PLC or SIGLIB scripts.  Not sure why that would be needed, but it would be possible.  You can also do the same with outputs, as long as the LUA scripts and PMC don't care which one set the output at any give time.  In other words, if you don't care about a "split brain" type of situation. 

Yes, the PMC is running instantly.
