General Mach Discussion / Run from here returns to 0,0,0 sometimes

« on: December 30, 2012, 08:18:37 PM »

Occasionally Run from Here will return to 0,0,0 (not in the code, just moves to the origin; the DRO shows it; the Code Window holds on the line it's supposed to be going to) then return to the line selected, then continue on.

Doing a feed hold, then full stop.
Rewind to beginning
using go to line number to select the line
hitting run from here
then letting it go to the Preparation Positioning

I've done this exact sequence about 50 times, and about 10 times it returned to zero; the other times it ran as expected.

I've been running hundreds of jobs with previous versions over 10 years; this only happens with the latest stable version; R3.043.066 I installed today.

Was using 1.84 for years; the past year or so running 2.48. I recall versions previous to 1.84 doing this.

Any idea what I'm doing wrong? Or is this a known issue?

General Mach Discussion / IMACH P5, acceleration, MACH Version

« on: March 03, 2011, 02:53:09 PM »

Just got the VistaCNC P5 pendant and noticed stalls when reversing directions in C or S mode ... seems the acceleration was a bit low - anyone else seen this issue?

The P5 manual rec's 2.63 or higher which is what I'm using. Any benefit using MPGs like the P5 with newer MACH versions?

Any settings i should be aware of? My machine has run well with CNC jobs for the past 8 years... using Gecko 201's, std parallel port, 74ACT buffers as per Mariss.

Also - any issues with higher accelerations on typical MAXNC BSA antibacklash nuts?  My MAX is oversized, Mitch way back when made me a 22" x, 20" Y and 22" Z so it's a bit more mass than a standard 15...

Also have issues with the P5 losing comm with MACH 3, just stops working. unplugging and replugin the USB seems to get it going again.
