In which case, Mercury CNC appears to be a commercial entity:

Sure.

It's 130x130x36mm, two sided machining operation with an 8mm endmill to rough, 4mm ballnose to finish. Ideally I'd have used a long tapered ball nose but didn't have one to hand, so had some...

Another little project:

4 Twist Umbilic Torus. What's cool is it only has one face.

First project with openSCAD programming to generate the shape, which also allows all...

Yeah, just a bit of a experiment really. £130 for a 10W 450nm Laser Tree 80 24V from their AliExpress store.

Made the first couple of cuts tonight - was a bit of a bitch to setup and I'm not...

One thing to think about is where the stress comes from - Its all about the cooling and contraction of the weld as it goes from hot hot hot to room temperature. This is effectively quite a short term...

Thermal linear expansion coefficient of Steel, ballpark 11.5 x 10-6m/(mºC). Aluminium is 22.0 x 10-6m/(mºC). The difference is therefore 0.01mm per degree, per meter of material. Lets say expected...

And last, but by no means least, my Daughter's Christmas present. I took a few months over this one, which probably says more about how little free time we get these days!

I saw the solid oak toy...

Evening Folks.

One of my original aims for this machine had been to help with the other half's glass work. We've made jigs, and aluminium bead making tools, but until now haven't touched glass...

Bargain price. Hope you get a sale sorted soon.

My wife and I had our first child over the summer, so haven't had an awful lot of time in the garage....! But I have managed to apply the inlay technique to build a set of toy blocks for her to play...

Robertspark's UCCNC Macros, Screenset and MODBUS manual is also a very helpful reference. See attached. Not only does it highlight all the inbuilt macro functions, but also has tables at the end...

I've recieved a question about my UCCNC setup, so thought I'd share and discuss my config in public, just incase it helps a future builder.

The vast majority of these settings are taken directly...

Thought it might be interesting for others designing their control boxes to see why I've made my new one like this and how it works. Also welcome to hear any improvement suggestions.

My typical...

Hi Kit,

Unfortunately the ntdll.dll error is quite a common one, but common because it can have a wide array of causes. It's basically the Windows kernel is freaking out and killing UCCNC. The...

I would suspect that the "pin number" is referring to the microcontroller, or the simulated LTP port, so its not straight forward. Pin 1 goes to that relay, and by the looks of things pins 2 and 3 go...

Quick update to the Aluminium Bead Presses. Other half demanded six sizes of the 3D hearts in both a horizontal and vertical press. Settled on a 0.2mm step-over - we did some tests lower down but...

Its a combination of both. Lets start a pros/cons list! Hopefully everyone can add/remove. I don't think you can make a general statement about what sizes of machine would be more or less likely to...

Ooops. :)

Force of habit I'm afraid... work requires kV / MV... You know what I meant!!

Wow that's some serious brewing activity...

Don't worry about phases in your calculation. Just take that single phase value, 4A or so and go with it.

If your Calcs end up needing more than...

Are you sure there aren't just two threads on the screws? I initially thought the same thing, then realised if I follow one helix it goes 10mm in one rotation.

Hi Joe,

About the stalling, have you tuned the motor current PIDs on the motor drivers? I have EM806 rather than AM882, but I think the process is essentially the same, connecting up the RJ11 port...

Depends on the amount and size of your cables! I measured the diameter of each, approximated them as square boxes, and then calculated the internal area needed. Then you want to fill to about 60%.

I'd be very happy with that as a first welding attempt - nice one! But yeah MIG isn't going to be best for that material size - I'd be surprised if it has enough penetration.

What's the phrase?...
