The Lagun will end up being my only mill, once I sell the round column mill that it's replacing.
If I don't get ball screw I will have to live with about .022 backlash on X and .011 on Y. That seems like a lot to me but I have no experience with this so I don't really know. The Rockford ball screw conversion kit is $1,000. That's a lot so if I could cut good circles without ball screws that would be great. After servos are installed is it not possible to run the screws manually? More confusion on what to do??
The folks at homeshopcnc.com have the .631 OD screws that would cost way less then half but the feel they are to small for my full size mill. Any thoughts on this?
The Gecko 340s and 38 volt ametek motors sound good but, oh how to wire them? And what about a power supply and breakout board? And the other stuff I don't know about yet?? Remember I'm a rookie at this and if I purchase parts here and there, I will need lots of help getting it all running. You are offering however and I will be taking you up on lots of tech support. I would like to look at the ametek motors. Where can do I find them?
As for the overall cost, that is a concern, but not the main one. I want to end up with a decent conversion here but I am all for saving money too. $1,000 to $2,000 is expected but if I can spend less I am all of it of course. My expectations of this mill are not super high so maybe I should start with the motors and stuff and install the ball screws later if I can't live with the backlash. Does that make sense?
Thanks,
