I now understand that there are hardware controllers and software controllers. LinuxCNC is a software controller, circuit boards like the TinyG are hardware controllers (that receive gcode). Just in

Hey Royce, MESA doesn’t make the stepper drivers. Just the interface from the computer to the stepper drivers. So how are you creating the step/dir signals from the Pi to the stepper drivers? With

I use NEMA17s for my Unimat SL conversion. ?Get dual shaft versions since they allow easy manual override. I use cheap Chinese stepper drivers, although MESA may be simpler. I now use a Raspberry Pi

Peter, This is one option for a 3 or 4 axis set of drivers. Reasonably inexpensive. I even bought two more than 10 years ago and haven’t used them yet.

Thanks John for the replies and the comprehensive information. Nice YouTube video too. I’m in the UK BTW. It may be far more complex than I first thought! Some serious research will be required I

Oh and BTW, I did find that the Arduino based electronic gearing required a 600 PPR encoder but apparently the encoder they recommend doesn’t have an index pulse (Z). LinuxCNC needs an Index pulse

Hi Peter, There’s no end of stepper motors and motor drivers in various combinations. And everyone will have an opinion on what is best so I’ll leave that to others. On my Gingery Lathe I have

I'm lucky enough to have about three quarters of a second Unimat 3 to play with, and (while this is a huge rabbit hole that I probably don't need to dive down) I'm interested in trying out some CNC

I got my U3 with the intention of making small parts for large format cameras and accessories... but so far I've mainly been working on things to 'improve' it (DC motor, collet holder, threading

Does anyone know what the thread size is on an ER-32 collet closer nut? I want to adapt my Unimat the nose to fit the collet closer nut. Thanks, Dick -- http://www.homemadetools.net/ forum/ OFF-

I'm trying to do the opposite. I just got the same motor. It is packed with decades of dust and grease and I'm trying to take it spart to clean. I removed 2 long screws and 4 screws that hold the

I turn more wood and plastic on mine that any other materials. Steel and Ali I normally do on my larger machines.

Hi needed to change the motor on my Unimat SL as it kept tripping the power. I bought a 12v DC motor and a cheap PWM speed controller for it. I 3D printed a pulley for the motor so I could turn a new

You'll be way happier with the 24 VDC conversion. They have comfortable power and run cool. The power supply and switching speed control are not expensive. And replacement motors are inexpensive. Neil

I was assuming that any power supply would built into a decent casing, with a mains switch, and maybe a separate on/off switch for the output. A power indicator and an output fuse would be normal. To

Thanks for the tip, Carl. I seldom work with plastic, but will remember you advise if I do cut plastic. I do have a speed controller and can adjust the speed down to a crawl if needed. Larry

Factory options to use the unimat for wood were many. Table saw, jig saw, planer, Tool rests, mounts, table router etc.?Jeff

Why not John! If it works - do it! I've used my U3 for woodturning but I just used a standard metal-turning HSS tool (well-sharpened) which gave a perfectly good finish though I did have to hold a
