In theory it could be done but you would (probably) need a NEMA 34 rather than a NEMA 23 motor. --- End quote --- I know I have seen at least 3 builds with direct drive on the Zone. CNCfusion's kit is direct drive as well. Just trying to figure out which has the advantage. --- End quote --- I was only looking at the home grown conversions not the kits - installing a kit would be cheating :D |

No worries, I won't be cheating! :headbang: There was one guy who did a direct drive solution that I liked at one time. I was thinking of using his idea but belt driven instead of direct drive. But ofc, I want to do the best job possible. so I am looking at how everyone has been doing it. But what is optimal gearing? A 2:1 ratio? I have no idea :scratch: |

I did see one conversion where the Z axis was internal to the column. A slot was machined behind where the rack goes to allow the ballnut to connect to the mill head. Despite a lot of browsing on cnczone and the Yahoo groups, I've been unable to find it again. It looked like a good way of keeping swarf off the ballscrew. Of course to do this would require a second mill... |

I did mention I have a second column right? :zap: But I am not going inside the column. For some reason slotting the column doesn't sound like a good idea. Eric |

Wish I could buy things like a second column or base here. The only way I'd be able to do that is to buy a second mill :( |
