General Mach Discussion / Re: Help please....mach3 jumping to reset when i cut any deeper than 0.5mm

Been quite regular here too Roger,
the strange thing is if i run it from an extension cable to the house into a Kitchen wall socket it never trips, now i had an electrician install my garage with full power and fuse box with an extra earth strap just for the BP.....it trips....not always though ...some days i would be running the BP for a few hours and no trip....other days 10 minutes and a trip, had a sparky down with his boss on the phone ...they were still baffled......the garage is on its own breaker on the house consumer....makes sense what you said though....its a common thing now.

HSM advisor looks similar to what i been using, only on g-wizard it only gives 2 options for alu, cast or wrought.

Thanks Hood i owe you a drink!

replaced the top bearing today and its running noticably quieter.......i wont be taking it past 2500rpm in future, i adjusted the QC nut too, it tightens right up now when before it came to a stop and didnt feel that tight.....i had to make some screws to fit it, and the longer one to stop the nut totally unscrewing, its got 6 screws instead of the 3,
ran it tonight using some 20mm mild steel.......faced it, shaped it, put a couple of 12mm pockets in it then chamfered the whole edge all using the midi function, everything went really well, then i turned the mill off and it tripped the lecky, everything went black and i banged my head trying to get out, then the misses gave me a wollop for bringing chippings in the house,
so im sitting here with 2 lumps on my head...... progress

Top spindle bearing goosed........just ordered one (7209)....bottom 2 seem fine.......im using g_wizard for the speed and feeds... i know the mills only 2hp...didnt think 20mm was that bad to be honest....im still learning though.

Thanks

Oh well that must of been a lucky cut...tried the mill today and it stalled again in mid path.....cutting at a light rough pass with 0.5 depth  sooo
i detroyed more stock and time and money.
im about to give it all up after 8 months of loss after loss after time consuming headaches....i wish i never bought this thing....its a bridgeport that wont cut aluminium....


thanks
