When I got the Lovejoy couplers mounted I compressed the connectors a little and that seemed to get rid of most of the backlash. I think that those connectors will work for now, if I get any major...
The ball nut off of ebay worked and it is now mounted to the z-axis. The z-axis stepper motor should arrive tomorrow. After that, I should be able to start milling.
I ordered that ball nut off of ebay I believe that it should work with the ball screw that I have.
I also found a shaft adapter on McMaster that should work much better than the ones I am...
Are the x y and z-axis powered by stepper motors if so it shouldn't be too difficult to control those with new stepper drivers. You said it is a three-phase machine I assume that means that the...
I was looking for a replacement for the ball nut that I broke does anyone know if this ball nut is compatible? The ball nut says THK BNT 1405A AX-1A101. I also will post pictures of the ball screw...
I am not using linux cnc i am using an arduino with the grbl firmware on it and controlling it using universal g-code sender. I might upgrade to mach 3 in the future but for now i am using an arduino...
I added a switch to control all of the power going to the electronics there is a junction box on the back of the machine where I am going to add an outlet for the computer and monitor so that they...
Quick update the machine is now on the stand in real life I did have to take it apart to the 2 frame pieces which means I am going to have to retram the x-axis to the machine. I am going to make an...
I added a stand to the CNC here is a picture of what the CAD model looks like with the stand on it. According to the CAD model, the machine weighs 550lbs. This CAD model also shows what I am thinking...
For the z-axis of the C.N.C. I was thinking about using this ball screw - https://www.amazon.com/gp/product/B076PKL6KV/ref=ox_sc_act_title_2?smid=A3E9T3KQ1YPBBY&psc=1
I would probably use the same...
I am rebuilding a Lab-Volt C.N.C. Router, When I first took it apart it had non-working stepper motors and electronics. When I took it apart I didn't intend on rebuilding it originally so I don't...
I bought a 1 hp treadmill motor that is 6000 rpm
https://motorsandcontrol.com/media/document/file/datasheets/9433.pdf that is the motor driver i am currently using
The reason I don’t want to go with a kress is because then I couldn’t use the r8 collet

Low rpm control would be nice to have but I don’t see myself using it often, I normally had my spindle at max or almost max rpm.

If i can figure out a power supply and a cooling solution, a brushless motor is probably what i would go with. I have a 24v 15 amp transformer but I don’t think that is enough to drive the motor.
...
i know what motor controller to use, i don't know a power supply that would be able to power that motor.
i have no idea what power supply i could use to power a motor like that
https://hobbyking.com/en_us/turnigy-g60-brushless-outrunner-300kv-60-glow.html that is the motor i was thinking about useing
the motor i was looking at was 1400 watts brushless and there wasn't any torque information
i did just remember one think that might be a problem the belt and pulley system that is on there has a 2:1 reduction, that is one reason i thought the hobby brushless motor because i found one that...
Would the DYN2 AC Servo Drive and the 86M-DHT-A6MK1 work for a spindle?

I would like to try to keep my rpm low and use the r8 collets, I would be willing to spend more to get a quality product that lasts rather than replace the brushes and contacts. For the servos what...
I am trying to figure out the best way to get my mill up and running again, i am considering all of the ways of doing so then i will do what ever is best. Right know i think the best way is to just...

Those are the pictures of the bad spindle...
And the motor that was on there is 90v dc.

I have a motor controller that i controller with a 5 k ohm potentiometer

What do you mean the nature of my present drive? And i would like a relatively inexpensive spindle solution.
