Hi Group I have a nema 42 sanyo denki type number 103-8932-0240 stepper motor which I cannot find any data for on the sanyo website. It is a 3.6 volt 6.1 amp 8 wire motor that is probably very big

The Chevalier CNC I used for several years had a manual mode in which servos were fully disconnected, and no pronies, etc. ALL mills will occasionally send the table flying if table locks are not

I hear what you're saying about the slop in the drill press. Another idea I thought of was to mount a hand router stationary above the cross slide. Aren't routers supposed to be made for lateral

What is a "prony brake"? I have a pair of servo motors but they do not seem to provide any resistance with the power off. I want to be able to use the machine for manual machining as well as

We switched our gantry router design from steppers to servo motors and now have two ah-ha PS4000 motors for sale ( Pac. Sci. mod # K42HLHN-LNK-NS-OO)with 35' factory power leads. They have never

The caveat on using a ballscrew feed in a manual mill is because the ballscrew provides virtually no friction, compared to an acme screw feed. You'd want a small prony brake, or some kind of damper to

Hello, The scales I have here are 600mm length that I bought for $49 so something changed price-wise. The way I understand it, the 25CPMM module actually has 2 light sources in it that are
