hi rob- im near cardiff.
i decided as these hy are chinese units id buy a spare for my hobby development machine- just in case.
just happens that my hydrovane has a 4kw 380v motor- not dual voltage- that i can use the "spare" for . (no 3 phase at my house)
the hydrovane is way quieter than my other bang bang compressors- which drive me nuts when running.
here is my development machine when i first got it going months ago-testing a vac pump, before adding the 9hp spindle etc.
https://www.youtube.com/watch?v=f8jixb2ax9Yive just added a energy monitor to see how many KW im dragging off my single phase supply. (should be interesting/scary)
i have been running a massive 55kw generator here to power up conversion machines in the past- trying to get away from doing this !
ive done a lot of conversions with mach3/ galil controllers etc- and had to write lots of code for them in the past.
my next project is to convert another biesse machining centre this time to uccnc. (using a galil and using the step/direction and gearing it to give an analogue output for the old analogue drives) - using modbus for all i/o .
i keep a facebook page updated with progress etc. join if your on it.
