With the frame welded up it's time to fit the fixed (X -axis) rails. As described earlier, the rail, ballscrew and motor for each side are all mounted on a single piece of 65 x 65mm hollow steel,...

How things can change in four months!
When last I wrote in this thread I expected it to be at least another six months, possibly 2022 before there would be anything new to report. Circumstances...

I've just checked both the UK and Australian RS websites and you're right. Free delivery for all online orders for those of us living down under but not for you poor souls still living in pommieland.

Nope. I'd say you're in exactly the right place to get help producing precision work of any size. Sadly I'm not the person capable of providing it on this occasion :culpability:

Andy,
That's a very informative and encouraging set of photographs. And a dire warning re starting fires in awkward places! I'll be reassembling my own machine in it's new home before long and a new...

Welcome aboard Phil.

Now that really is from the minimalist school of aeronautics! Even 'Little Nellie' looks like a heavy lifter by comparison.

I'm with Clive on this one. 3mm tools are cheap enough so keep the 1mm depth of cut (or maybe up it to 1.5mm, 50% of the tool diameter) and crank up the linear speed in steps until you break the...

I once read a forum entry somewhere that suggested the way to set your feedrate was to increase it until the tool breaks then back off 10% and replace the tool. I prefer to use HSMAdvisor but it's a...

More seriously:

When I was looking for ways to soundproof my extractor I did some Googling and found this video on YouTube. I've just managed to find it again. If you don't want to spend the time...

This entry isn't the 'Build Log' it's the Un-Build Log! Ironically after spending so long designing and building, re-designing and re-building and at last getting the beast nicely aligned and ready...

Welcome Alan,
Sounds like you have enough interests to keep boredom at bay. You'll be in good company here.

Personally I think the guys in that video are barking mad! But plenty of people think that of me so no problem. The most important thing to understand about the whole process of making gramophone...

Some door sensors are made so that you can pull the pin out towards you to overide the interlock once opened. This will automatically reset when you close the door again. These are best used when...

Bernard,
Looking forward to exchanging clock design notes with you. I've built a couple of Sextus (design by woodentimes.com) weight driven clocks but am now working on electric designs powered by a...

It's true that Art isn't as young as he was when he wrote MACH3 and brought CNC machining to the masses, but he still retains his idiosyncratic sense of humour, hence 'Gearotic' :emmersed:

Joking...

Another Australian wooden clock builder! Welcome to the forum.
I got into clocks by accident after building a Heath Robinson cnc router and wanting something to test what it could do. I'd never...

One of the reasons for mocking up the design in cheap MDF or plywood before marring the pristine beauty of your expensive aluminium plate.

I have M8 tee nuts in the underside of my plywood baseboard with a drilled MDF spoilboard on top but I doubt you will allow anything so porous or flexible onto your machine. My spacing is 100mm and...

Not sure about Mach3 but in LinuxCNC the gantry runs to the switch at relatively high speed, backs off a few mm and then runs back to the switch again more slowly to get a more consistent homing...

Meant as a compliment! Your range of experience is unique among forum members and as a professional machine builder your customers would have told you loud and clear about anything that didn't work...

I'm with you Doddy! There's a definite new social possibility in this thread... "come round for a free beer and have a look at my home-made CNC machine". I might be abe to make some friends!

It is...

Gcode is nothing but text so you can save it with any extension your email will allow. .txt for example and change it to whatever MACH3 wants on arrival. If it's the file size that's the problem...

Giff,
I think you have to make a minimum of ten posts before you can access some functions of the forum including adding pictures and probably sending PMs.

If it's timber joints you're interested in, this an interesting source of ideas.

CamBam is very capable, especially once you discover the webpage full of add-ons and the forum to go with them which extend it's abilities considerably. I also like the license which is a 'pay once,...
