Sieg KX1 & Mach3 won't come out of emergency reset

[lateAtNight]

Ahhhh, guys. I must admit I haven't been keeping track of this thread... and I'm sorry I haven't . I assumed it would be dead and I was waiting until I actually had a proper update on the problem.

Lol. Soooo... I was considering bridging out the estop on the control board. I ran a multimeter to check for continuity at the guard switch and at the estop... all seemed fine. Before I bridged the circuit I wanted to eliminate a few other things.

On Wednesday I plugged in w/laptop and it wouldn't come out of estop, so I went to considerable effort to lug my f'in huge workstation style PC out to the shed to settle the possibility it could be the laptop. I also switched out the USB cable and on the recommendation of the smallcncsuport guy (John Stevenson... maybe its John S who kicks around these parts?) I added a 400ms debounce to the input signals in Mach. I also replaced the guard cover.

It came out of estop straight away, and I was already to eat my own words regarding the laptop but sadly my happiness was short lived when the same thing happened on the PC... half way through-ish a small op the machine went into estop and wouldn't come out. It just about broke me and then I almost went nuclear. So I just packed up and went inside. Didn't get a chance to try the bridging thing.

I was already to try this evening when I plugged in and once again all was fine... I thought I'd give it one more chance to make it all the way through a small part and it did. So I have my first part (ish...). Only then I went on to realise a much different problem... I wanted to do a little drilling on said small part and relaised that two of the MT2 ER16 collet chucks I have don't fit my machine! Wrong thread. Just can't win.

I went back to have a look on eBay to check and the listing now says "These chucks are threaded for drawbar but unfortunately we cannot confirm the threading size or pitch because each batch might be different." I was well aware my machine has an M10 thread so I am dubious it said that when I bought them (it was back in the spring), but I guess I'll never know now.

I'm still concerned the estop is a problem and worried about doing a bigger part. Only time will tell I guess.

For anyone interested here is a shot of the internals of my machine showing the controller card:



It appears to be this one: http://www.automationtechnologiesinc...breakout-board. Known as an AKZ250 or Xulifeng. Looks like an FPGA at the heart and some kind on Atmel SAM (i.e. ARM) based device for usb coms.

I never did get rid of my Galil card (its in my workstation style PC which I am planning on switching to a smaller case at some point) so it could be a potential replacement if the card if its at fault (its PCI BTW so I can't wage in on the usb / ethernet war :D ). It would be a massive job and one I shouldn't have to do!
