A follow up - "Chaoticone"  was correct - Mach3 reset the "Estop" line to active when restarted - obviously a well thought out approach to safety.  I also went  back and reread the Estop section in the manual - there is a short reference to this issue (easy to over look).  

Lesson learned - read the book carefully with a yellow highlighter at hand.  

Nice software - I'm impressed!

Thanks guys & gals,

Very interesting!  I can see that Mach3 has far more capability than my little set up will ever need.   And clearly - your have to dig really deep into it -- to fully appreciate it.  

I did change the ESTOP pin assignment but haven't been back in to it to see if indeed Mach3 turned ESTOP back on.

Now that I have refreshed my Mandarin, I think I have this BOB figured out and will get serious about setting up a profile for my hardware.  Which will of course include a couple of ESTOP buttons and indicator lamps out on the table proper for safety sake!

Thanks again for the responses and your willingness to share info.   I'm really a green horn with regard to Mach3 - but have spent a career around servo systems (2000 hp DC and AC inverter paper mill & steel mill drives - hydraulic flight controls for S1B & S5 and others).  If you need to move something really big - precisely - drop me note!

Have a great weekend - CU at the "home" position!!   ;D

Got IT!

All else fails - READ the screen!!

On the line to the right of - and next to - the "Reset" button - the message  "External emergency Stop requested !!"    Duh?

With nothing attached ..... I certainly was not expecting that or looking for it - but sure enough --- when I checked "Pins & Ports"  down in the bowels of the pin set up - the Emergency Stop input was the only input assigned and active by default - to some arbitrary pin.   Deactivated and applied the new configuration and the problem went away.  We shall see if it comes back when configured for my externals.  It's probably based on a "normally closed"   -- "emergency stop"  loop and with nothing attached to the port - it's "open" and calling for emergency stop. Isn't that special!

"Greetings Professor Artimus, Would you like to play a game?"

What threw me ..... this didn't happen on another computer (a laptop) that I setup just for reading and browsing the Mach3 app while in my recliner!  

But .... when I installed it on the desk top PC I've designated as the CNC control machine with a real LTP - it did something a little different. Not sure why  - defaulting the emergency stop loop input to "ON" is probably not a bad thing   ... to avoid legal problems at best - prevent a few truncated digits at worst!


OK so now - tomorrow - if I can find a cable - we will connect this tired old PC to the new Chinese ::)  BOB (Break Out Board - took me a while on that one too!) and see if we can make a few lights go blinky blink!!

I hate it when I start answering my own questions!

And did I say I found a really neat, kinda basic, g-code generator - F-Engrave (Windows)  --- gen'd up some quick and simple g-code files just to play with with on Mach3.  a FreeBee to boot.

Hang in there CNC'ers.  

This ole red neck is gonna get this puppy a goin .... finish up the rocket ship ---- and Desdemona and I are .... out a here!!  

ET--- were coming home o'buddy! ;)

Nic,

The term - "off line" has nothing to do with the internet and being "online"  in the classic sense --- per the Mach3 manual --  Section 6

 "" 6.2.15.4 Offline This toggle and warning LED "disconnects" all the output signals of Mach3.  This is intended for machine setup and testing. Its use during a part program will cause you all sorts of positioning problems. ""

The Button is directly below the "Ref All Home" button on the default "program run" screen.

------------------------

Now ..... having cleared that up (?)    ........  from the literature there seems to be a long standing issue with accessing the XP parallel port .....  I'm just so new to the whole Mach3 world and haven't used a parallel port for much of anything in the last 15 years   --  what is likely a very simple solution   ----  is just not on the top of my "tips & tricks" buffer!!

Thanks again for you interest

Learning Mach 3 -

Loaded the software - seems to run fine but I can only get it to reset (and run) if I push the "Off line" button  - the write up said it was a common problem but did not suggest any fixes. 

I assume you have to be "online" to get any output to the parallel port.   

I've poked around the parallel port - think I freed it up from a previous printer installation shown in the "print server" dialogue - not sure what else could be tying it up.   Addresses look correct. 

Got to be something simple.  Stripped all the old apps off the computer - will be dedicated to the engraver/router 


Looks like some nice software - picked up a nice XY engraving table but had no controls - just got a BOB and Drivers for the steppers - but haven't made Mach3  hook up with the port.

Thanks for the reply -

Ok until I figure out how to search all this stuff - WHAT ARE THEY??

XP Pro SP3 on an old IBM NetVista - Intel 486 1.8g - onboard  motherboard   ECP Print Port.

Ok .... which end does the little three prongy thingy plug into --- ?  

Computer - I don't need no stinkin computer - SlideRules forever!  

Steinmetz was my hero!  What else you wanna know?

Tesla rules!

What is a LPT1?  

Stupid questions, deserve stupid answers!

Yeah, I gotta a CNC machiney thingy .... and I'm building a rocketship .....  we gotta get off this planet!!!  

My home is in Alabama - chicken farmer & I build Rocket ships on the side (the rockets generally point up - but not always!)  - just an ordinary red neck!

Dream in code!!  .....    E <=> MCC  

There are things in the universe we do not understand - #1-women  #2-Black holes(Trump)  #3- Mach3  (somebody must know something about it around here?)   [uh forgot #4 "Windows" !!]
