Hood,

    Interesting....  This was a fresh install of v3.041 on a new laptop.  Is there some configuation I need to do?

Hood,

    Code is attached.  Note this is setup for 2D milling, manual Z, so there are M00s where each Z move would be.

Hood,

   Well, it sure gives a lousy estimate of the run time, then.  It's off by a factor of 10 or more.  When I try to run it normally, it just hangs at line 110.  No DRO updates, no path updates, nothing.

Also, the simulated run time is WAY too short (indicated 6 minutes, when actual run time is close to an hour), and the timer keeps going after the run has ended.

Gerry,

    Interesting.....  I never changed the IJ setting when I installed Mach on my mill,, yet it's always been incremental.  On this install, it came up absolute.  So, it now runs through the entire program - very quickly.  Is the purpose of simulation just to see that Mach doesn't gag on the code?  Can I make it run slower so I can see what it's doing?

Well, the problem I'm having is when trying to simulate known good code (I've cut real parts with it...), it executes a few lines, then dies with a crytpic error:

"Radius to end of arc differs from radius to startLine 18"

Here's the pertinent part of the G-code:

Dave,

    That was simple enough!  Thanks!

What do I have to do to start Mach without loading the driver?  I want to use it for testing G-code on my laptop, so I don't want the driver to load (last time I tried with the driver, it locked up the machine....).

You might want to go to cnc4pc.com, and buy a set of replacement chips for your C10 board, or just order from Digikey or Mouser.  Sounds like one of the 74ACT245's is toast.

General Mach Discussion / Re: Machine loosing position when estop

« on: September 12, 2008, 07:26:49 PM »

Since i installed the dev version of Mach and the SS I notice that anytime I hit the Estop button my machine loses its position on the axis thats moving. It only effects the axis thats moving when the estop is hit. Is there a setting I have missed somewhere/

If you want to stop gracefully, and not lose position, use FeedHold, not E-Stop or Stop.  Using E-Stop when the machine is moving is pretty much guaranteed to lose position, as Mach simply stops sending step pulses, and has no idea how far the machine will coast before actually stopping.
