General Mach Discussion / Re: Sudden stop

« on: November 14, 2009, 10:14:25 AM »

It would be helpful if you could provide more details.

Was anything shown in the Status box after the stop ?
Was it an e-stop or limit switch triggered (Reset flashing) ?

A couple more parts made for the grand jigsaw puzzle.

LED display panel, again isolation routed and the legend panel engraved in traffolite.

Could it be exactly the opposite to what I have said before and your PC is running too fast ?.

General Mach Discussion / Re: Second parallel port for use with THC

If it helps, I use two ports. The address in Mach Config for Port 1 is 0x378 and Port 2 is 0x278.

Tangent Corner / Walking the Dog.

« on: November 13, 2009, 08:23:48 AM »

Last week my neighbor was taken ill and she asked me if I would walk her dog.
She said "Don't let anybody poke fun at you because you are walking a small dog".
Nobody did !.

Now that's what I call a powerful setup Mika - I could break some serious tooling with that.

Some further thoughts....

Try running the 'DriverTest.exe' program (found in the Mach3 folder). This will determine if your PC is struggling with running Mach.

My workshop PC gives a nearly consistent flat line which is the ideal.

General Mach Discussion / Re: adding stop to all z movement

Most controllers have an 'enable' input for each  axis (check your manual) and I have each of mine connected through a switch to ground so I can easily disable any axis.
As Jim has said Mach is unaware of this and runs as normal.

It sounds to me like a limitation of your PC.
Mach is using a lot more processor time when running the full screen as opposed to the tuning page and if your PC is doing other stuff (such as polling USB etc) glitches will be experienced.
If you have one, then trying another (perhaps faster) PC may resolve the issue. (Others have posted problems like this when a USB dongle is present which disappears as soon as the dongle is removed)
