Electronics for New Machine + Chinese Spindle + VFD

[njhussey]

Martin, don't underestimate how much more powerful this machine will be compared to your last one. When I built my machine I had it upright on it's end whilst I was attaching the Ali base. Whilst it was there I stood on the gantry and just like unscrewing a bottle top was able to turn the ballscrew and lift my weight (19.5 stone) with no effort at all. Now I know that if I accidentally get an arm/finger/leg(!!??) stuck/trapped whilst trying to hold something down (I know, I know, I know you shouldn't do it but.....) then I know for sure that if I press the E-stop I want it to stop dead 100% guaranteed...not be reliant on software to do it for me....

It all comes down to what you want to do safety wise really, have you given any thought to what you want the machine to do in the event of a brown trouser moment? As Dean says, for another £30 or £40 you can have a much safer system.
