Mach 3 throws reset

[dlaery]

I have a Taig Mill and having a lot of trouble when running code and out of the blue throws the reset. Usually it is in the rapid plane move, not cutting. This doesn't happen every time, but enough to cause problems. This is a bare bones computer. I have attached of what kind of computer. I was getting my G-code off of another computer through the network and have changed that so the code is on the computer with Mach software. I did just find Internet Explorer was on, so I have shut off anything to do with internet. I keep the mill oiled, the motor don't sound like they are binding up in any way. My couplers have 1/16 in gap. I did have some moisture in the plug on the spindle motor, have dried that out. That just caused the motor to stop and not the reset. Broke a bit on that. This mill is 6 months old. Has not run 10% of the time. Has anyone else had problems like this and know what to do?

Thanks for looking.

My problem usually occurred when I turned on a fluorescent light.

Now I use a different PC the problem is gone, and the homing switches are more consistent.

This points to a poor quality parallel card in the original computer.
In the original computer I needed to buffer the limit switches to the PC for reliable operation. This problem went away also.

It was a parallel port integrated on the mother board.
The brand name PC used now has a parallel port that electrically meets the standards.

On the original one the inputs were pulling up too hard, hence never pulled low adequately, with standard TTL drive.

This was caused by the configuration of the integrated chip not conforming to TTL conventions. I'm sure some printers would not be very happy with it too.

Is there an error message?

What Taig CNC is this? Need more info on the controller.

Have you disabled ACPI on your computer and run the Optimizations for Mach 3?

Is there a message in the status line at the bottom of the Mach screen? I suspect you have noise problems that is tripping a false limit or EStop.

Thanks, neilw20. I have wondered about this computer with dual processer.
I thought I had attached a couple of pics but here they are of my computer and the mach 3 screen shot.

fretsman this is a DSLS30003X This is where I got it

I have not done this

ACPI on your computer and run the Optimizations for Mach 3?

I will try that.

ger and jeff the error just says "Limit Switch trigger"

This has happened several times and I think it has said the same thing every time.
I have been running this morning (same code)cutting air at 75 fro and has not reset yet. But I have done this before and it works and then when I go back to cutting, then it will happen again.

I will try your suggestions. I use this machine everyday and need to.

Thanks again to everyone!

It has hit a limit switch.
Get the soft limits working correctly, then turn ON softlimits.

Fix the units. DROs are in metric resolution. Your program is in inches, or the part is really tiny, with really slow feed rates.

I see you have NOT referenced the machine. (red indicators on DROs) Fix this first. The machine never has a consistent machine reference, so how do you expect the soft limits to work?
When a program won't run with the soft limits on, fix the program, or use realistic limits. You are never going to get past the stops with those small steppers!!

On the tool path screen, look at the extents of travels in the program and fix the problem, like moving a limit within the range of the program.

Also run all the diagnostics like drivertest.exe
You need 100% confidence in the machine setup so you can use it to it's fullest extent. From the Mach3 manual, do the full setup procedure!!!.

It is fine to be able to jog. That is the starting point.
When the setup is good backup the XML file.

With the program loaded, refresh the tool path screen to see where the limit problem is.

Your getting noise on the limit switch lines. Try increasing the debounce in general config. Try a setting of 2000-3000.

If you do not have limit swithces turn the inputs for them OFF.

The Taig DSLS 3000 uses the "limit switch" error function in Mach to stop motion when the servo-lock band has been exceeded - when commanded position gets too far away from the actual position as measured by the encoders. The Taig doesn't actually have any limit switches, and the soft limits are turned off in the standard Mach3 XML file that ships with this machine.

The fact that this is happening during rapid moves indicates that you're pushing it a little too hard for your setup. Try reducing the velocity and accelleration settings (in Config/motor tuning) about 20% for all axes. (Remember to click "save axis settings" after adjusting each one). The rapids are determined by these settings, so this should fix the problem.

I'm still reading the manual on the referencing. I don't think it has limit switches. I will look into the other suggestions also. You guys are fast. It takes me a while to absorb and to figure out what to say. Lots of good suggestions and places to look to narrow it down. I try to make one change at a time to see what works. I'll keep you posted.
I really appreciate everyones help.
Thanks,

Correct, but also keep in mind that if the parallel port is only throwing out 3.3 volts, it will trigger the reset faster than normal too. Even though the DSLS 3000 system is "supposed" to accept a 3.3v system, it does not work as "well" as a parallel port that accepts a 5v setup.

I know this from experience
