Yes I know Greg. But they are not worried someone has bought the land for houses and I think they got some serious money for it. Like probably 40 million nzd. So they just want it gone. And I'm happy as to get it! I paid 5k nzd which is about 3000usd so got it for a song. Just got home

Hey Andy. Heidenhain is not very well supported here in NZ. I went down that path already on my last machine and won't do that twice lol. They are actually moving and just want it gone now. And the 25k nzd was over 10 years with all the problems it had. It's almost as if it has a dodgy ground

Actually Peter and Andy. I have a 400v to 240v stepdown transformer on the lathe at the moment as fanuc uses 240v drives in Japan. The transformer is massive So I already have 240volts ac three phase power in the machine. Just need to rectify it I think. I have no idea currently how to

Re: [Emc-users] max motor size that a 8i20 can control

I don't really know much about it. there is a big heidenhain service manual online I found that mentioned it. apparently there are also extra boards that allow you to interface a 0-10v signal also which then converts to PWM in the inverter. So I bet there are pretty standard. If I do end up

ah I see thanks for that I couldn't work out how that was supposed to work so that is not going to happen then on the cnc mill. guess I will need to buy chinese servo drives and motors if the existing heidenhain inverter doesn't work and I can't interface with it. apparently it takes a PWM
