Strange X4+ problem

[irv]

Since the last post, I've run 5-6 different programs on the X4, and haven't had any strange Axis movements.

I have, however, had a few random E-stops. It happened twice during a facing program. The program just stopped(spindle and all) and Mach3 was flashing "E-stop button pressed"... and I hadn't touched anything. I started it over... it happened again at a different point in the code. I started it again, and it worked fine.
It happened again on another program, but this time everything just stopped, and Mach3 went back to the beginning of the code (no E-stop warning). I ran it again(with no changes) after that, and it worked just fine.

I'm thinking its just another case of "Syil Loose wiring" which also could be causing Mud's problem.

Thoughts?

Examine and tug EVERY crimped connection.
Poor choice of crimping tools creates this sort of stuff.
As for the E-Stop, have a careful look at earts on LPT cable and make sure screwed in.
Also ensure all earthing screws in X4 make proper contact.
Electrical interference often occurs running machine on a different phase to the PC/laptop. Try and use the same power point.

Sorry for lack of update, but been busy with the Honey Do list
I set Rapids to 40 units/min (conservative) and let loose with the code, after 10hr run cycle all is well. X4+ held it's position and cut through the 304ss with little problems. Thanks for all the help, just needed to slow those Rapids down a little.

Don't you just hate specmanship.
Find the maximum limits and back off by a healthy margin to allow for sagging power dropouts and overloads, and you will never have problems.
I fail to see why you need to 'cut air' at ridiculous speeds.
If you had a tool changer, then cycle times might be an issue but not with these little machines.
Well done, with an easy fix.
