General Mach Discussion / Re: any recommendations for pendant / mpg?

« on: February 25, 2011, 10:55:02 AM »

Thanks cj - sorry it's taken me so long to reply - I somehow missed your post. Must have got lost in all the other replies 

which one do you have? The P3E with the EE box looks like it fully handles E-Stop correctly - so might take a shot at that one.

Thanks again

PoKeys / Re: PoPendant 1

« on: February 25, 2011, 10:32:05 AM »

After a bit of reading it seems (if I'm correct) that wiring a popendant to a second parallel port isn't trivial. Firstly there arn't enough input pins on a PP port and secondly the pendant requires it's own 5V power source. Are these assumptions correct or am I missing something.

Noted. I'll go ahead and get the pendant and try it with a second parallel port.

Thanks

Thanks borisz.

However, I'd be interested to hear views from anyone who's using the above pendant with a second parallel port before I buy. I don't have time to mess, so I'd just like a solution that works out of the box. Clearly just looking at the threads in this sub-forum there are at least some issues using the pendant with a poKeys, but I don't see a lot of mention about using the pendant via a second parallel port. Any views/experiences/opinions welcome.

Thanks

Hi borisz

Bit confused with your reply. All I need to know is if I buy a PoPendant (see attached), am I better off connecting it via a PoKeys55T or via a second parallel port and are there any issues I should be aware of with either method.

Thanks

PoKeys / PoPendant 1

« on: February 24, 2011, 08:01:42 AM »

I'm considering one of these fellas http://www.poscope.com/product.php?pid=21.

Would I be better using it with a PoKeys55T or a second parallel port - can anyone give me a brief run down on the state of play with these and Mach3? i.e. are things stable/reliable (plugins etc.) or are there "issues". Any advice most welcome.

Thanks

I'm referring here specifically to Mach. I suspect there's a gazillion different gcode dialects and hence interpreters out there but other than that I can't comment. The % as the first character in a line is just an empty comment line to Mach so if you preferred you could do something like (end of my file) - the % is just quicker I guess.

The only refs I know of are those via the links at the top of this page

General Mach Discussion / Re: Steppers out of sync and skipped steps?

« on: February 19, 2011, 06:05:00 AM »

Why they wouldn't run in sync in parallel is very confusing, I don't see how they could actually run out of sync. But apparently they can.

See post #5 and others.

Chris - you're welcome.

The % isn't required but it's not a bad idea to put one on the last line of a gcode program. The gcode interpreter has a "quirk" in that it only processes a line when it sees a carriage-return-line-feed (CRLF) at the end of the line. It's easy to forget to do this on the last line (usually the M30) but in the case of a subroutine (like here) an M99. The % ensures (and visually confirms) that there IS a CRLF after the last line.
