Re: Rong Fu RF 45 vs RF 31 CNC - Help!

Thanks for the kind words about the conversion.

Not sure on the oz/in on the motors ( I got them from the trash )
However, they are working just fine with a 24 volt supply. When I up
the voltage to 50, things will be even faster. Currently, I get
10ipm on rapids, which is fine for the home/protoyping.

I am currently using the stock lead srews and nuts, there is about
0.008 back lash, but this is calibrated out with the software(
turbocnc )

The conversion was fun, and it can be undone if needed.

Have fun with it,
Joel
