My MX4660 just stopped working all of the sudden. The LEDs ont eh drivers are dim, and flickering. Power supply is good at 36 V into the MX4660.

Yes, I used the Castlelink software on a computer. I had to use a special programmer that plugs into the ESC. Might be a different feature of this particular ESC that let me do RPM control....

It's a servo signal generator that I use to drive the ESC. The ESC is set to control to certain RPM, it's a CastleCreations ESC, which lets you program it from a computer.

Don't have any plans for that, it seems to be in a safe area. If I cut steel it would stick to the magnets though.

I was surprised how well that burshless motor can drive the spindle. I've only had it stall out once when I made an error in movement speed and cutting depth. What do you mean by a cage? cage for...

There's something weak about the spindle housing. I think the way I have it attached is the weak point. I can fix that easily by just making myself another spindle housing that's beefier, and...

I finally got a video of this bad boy cutting some aluminum:

I have done aluminum parts that have multiple z-axis moves, but no 3D contour work.

I'm simply posting to attempt to contribute to this great community. I'm an avid RC aircraft hobbyist, and got into CNC machines to make things for that hobby. I started on a Shapeoko 2 and quickly...

To attach the linear rail to the extrusion, most ppl put a bunch of individual t-slot nuts in the extrusion. If you do this you have to position each one precisely to match the fastener pattern of...

I think I have the same overall structure as him. My machine is smaller too, I'm not convinced the extrusions are the culprit. There are a lot of extrusion-based machines that seem to do well with...

Torque RPM and power are all related. Power is RPM*Torque. Torque only matters when you can't produce enough of it at a certain rpm to maintain that rpm. I think it makes more sense that the...

This guy is using the same spindle I am, and it seems to tear through brass well. He is running at super high RPM though:

I'm not sure spindles need to be that powerful. In my case I was able to maintain RPM while cutting, and the motor only drew 100 W. That was a surprise to me, but the data is there.

It's a Sherline Industrial Headstock. I modified it a bit to be able to mount it flange style. spindles

I've seen some pretty badass router/mill builds that use the aluminum extrusion parts as...

Thanks. It was a gamble on my part. I fronted a large chunk of money to build this; it made me nervous. I really want it to work well so I feel good about it in the end.

Good question. I would be nervous about doing that, suggesting that it is indeed a weak point!

This part interests me, can you tell me a little more why tubes are...

/r/hobbycnc right? Ya that was me. Since then I've made the z-axis a lot taller because I needed more room. With this I can fit almost 10 inches under the spindle! Oh and BTW, the reason I have...

What I thought was a "brilliant" design of mine has disappointed me! I've made an aluminum extrusion frame router/mill with Hiwin 20mm rails and 1605 ballscrews. My goal was to be able to machine...

Are you sure they're angular contact bearings? Those ballscrews that we get from ebay and aliexpress usually have just deep groove bearings, and you need to use shims to adjust out the axial slop. ...

I must admit I dont' understand how to use the switches. I'd have to place them so very accurately that I don't think it makes sense. As far as the gantry sliding down, I do have that concern, but...

I think the belt would solve the missed step issue. If one of them screws up, the working motor will turn the ballscrew that normally would stay still during that moment. Technically I could drive...

Before I locked the z-axis ballscrews nuts to the gantry, it was resting on the bed with gauge blocks under each end (left and right), so that set the gantry beams level to the bed. I then locked...

I started with the Shapeoko 2, but the plastic v-wheels made me angry. I didn't see how they were even good enough for using the machine on wood. I then set off on designing and building my own. ...

I started with a Shapeoko 2, but those plastic wheels are worthless. I decided to make my own that is capable of anything I can throw at it. This one uses misumi extrusions. Guys if you are...

Ok I fixed it. Apparently I had to put the "charge pump" switch to the ON position. I didn't mess with this switch since I last checked things out, but I think Mach3 was set to enable charge pump...

About one month ago I test drove my steppers with the MX4660, UC100, and Mach 3. I went to do the same exact thing today and the steppers will NOT move. I confirmed with a scope that I have step...
