Just a quick note to say that I have released a new retrofit kit for the X3 mills.
I offer several kits ranging from basic hardware through to hardware, motors, controller and of course a registered copy of Mach3. Kits are easy to install requiring no mods to the mill and do not detract from table movement ...in fact the Y is increased!
Our controller runs nicely with Mach3 so even if you already have your mill hardware arranged then have a look at our controller ... 4 axis 40V 3A per axis, microprocessor based with nice features and designed by us with safety in mind.
