Mach3 under Vista / Mach 3 / Cut 3D crashing on Win 7 dedicated computer

« on: January 08, 2012, 06:34:20 PM »

Hi,
I'm trying to fault trace why my computer may be hanging during some runs.
The machine is a P4 running 32 bit Win 7. It is not web connected, has no anti virus installed, and I have stopped all the interruption applications I can find, including power down and screen savers. It controls the machine fine via a Gecko 203v based board.

I can access Cut 3D from the Mach 3 menus and work through the simulation processes in Cut 3D and generate .tap files.
The job will run fine in Mach 3 for 10, 15, 20 minutes, sometimes to completion, but the computer freezes and requires a hard reboot.

Does anyone have ideas about possible sources of crashes?

FAQs / Homing and <goto zero> issues

« on: June 26, 2011, 06:28:52 AM »

Hi,
Firstly, please forgive me for my ignorance.  I'm pretty new to this and I notice from the level of discussion on the forum that many posters are seasoned hands at CNC.
I'm commissioning a 3x1.2m 3 axis MechMate that I built and things are going fine.  It's able to move correctly in response to G code and the e-stop, feed hold and resume buttons all work. I'm running a PMDX-126 and Gecko 203v's and Mach 3 (2) is installed on a 32 bit gaming (i.e. high specced) PC running 32 bit Windows 7

I'm having problems setting up home are returning to zero. I do not have limit switches and have yet to get my proximity circuit sorted, so I'm slamming into end stops a bit!

1. I set zero for x,y,z with the machine co-ordinates lit.  This should be "table zero", right?
2. I can jog off this zero, switch off machine co-ordinates and re-zero, then regenerate path and and run through g code.  The display shows the work correctly relative to the table and the machine moves correctly in response to the g code.
3. If I <goto zero> at the end of the routine the gantry or car overtravel dramatically, which means I have to be quick hitting <esc> or <reset>.  I have tried debounce values of 500, 1000 and 2000.
4. I cannot subsequently zero any of the axes via the on screen buttons and have to restart the software to be able to do this.

Is there something I'm missing?
