    I cant believe you're driving a bridgeport with it, I bought this kit with an RF45 in mind.
    Post a few pics please? The breakout board is a rip off from Keling, wires the same. The driver PDF is easy enough to find with google advanced search, let me know if you cant find it.

    up an running

    I found a 78 volt power supply on ebay. It made ALL the difference. I can run the X and Y up to about 35 ipm. Even that's a little more than the acme screws want. They chatter sometimes. So I slowed them all down to 20 to 25 ipm. Even that seems a tad fast sometimes. I tuned them though the wizard under settings. Just above the reset button. Auto tune, best thing since sliced bread. Now that Mach3 and the hardware are getting along. I ran the circle wizard and the pocket wizard in space (the knee way down ). All seems well at this point. I think I need a to do something different with the Z drive. Either a different ratio or a bigger stepper. I tried to bore a hole with the jog, maybe a bad idea I don't really know. I set Mach3 to jog by step and set the step to 0.001. You can't feel tool pressure from the jog button so I may have been crowding it too much, but I could here the stpper miss a step every now and then. I'll take some pics and post 'em for you guys. Any tips tricks or comments are more than welcome.

    So much for the easy part.

    Here's a few quick and dirty. Sorry about the mess but I built it to use not to look at. The hand wheel is the original with a mod to the handle it self. Just push the button on the end and pull it out. I considered doing something similar for the Z but I'm shying away from that. I have a drill press. After I figured out Mach3 is geared for a touch screen I had to have one. Now let's get to the meat and potatoes and make something. I'm going to try a sproket. I use them on the hay elevators I build. Pretty low tech but vital nonetheless. I'll keep you posted.
