ess runaway on startup
« on: November 16, 2015, 07:38:50 PM »
I recently upgraded to a new computer using windows 7 and installed an ESS to get away from parallel ports. Mostly it has been running great. I have three problems though.
1. Occasionally on startup, an axis will runaway.
2. Mach does not require the reset button to be pushed on startup. I wish it did, maybe causing problem #1.
3. Occasionally its dropping tools during a tool change. This occurs when a solenoid should be fired to bring the new tool up into the spindle. It seems as if it skips firing the solenoid and continues on with the macro. I never had this problem on the parallel port.

Sounds like more a Mach 3 - Windows 7 problem than a ESS problem. What version of Mach 3 are you using? Warp 9 recommends Mach 3 ver 0.062 for ESS, not the latest 0.066 which has issues.

The thing to remember with the ESS is it is very fast.... way faster than the parallel port... so you need to slow things down a little maybe by adding in some debounce on the ESS Config Screen.

You probably need to allow for a delay in your code for the toolchange to allow your solenoid time to activate (the loop within Mach runs at 10Hz, hence it may try to run through your code so fast that your solenoid is not having time to enegise and de-energise.... also what is not helping things is how fast the loop in the ESS can run.

I'd suggest that Item number 1 and 2 can "probably" be corrected by going to the Mach3 >>> Config >> general Configuration tab, and down the right hand side there are a number options for "Pgm End, M30 or Rewind"....

I'd ask Mach3 to e-stop the machine by ticking the checkbox..

And see if that clears your problem.
