I decided to enter this year's Great Guitar Build Off to give myself a kick up the backside and get on with an idea I've been mulling over for a while. Here's the final entry video.

Unfortunately I had the same problem show up again yesterday. However, a look at the bug reports on the cncdrive forum included someone who got exactly the same shutdown problems when he unplugged...

Looks good Andy, nice feeling isn't it when you see the fruits of your labour produce stuff like this. Well done..:toot:

Hi everyone. I thought I share this here, even if it might not raise a very high interest.

A few weeks ago I had a discussion on another forum regarding spring loaded engraving vs drag engraving....

With the machines I build looks plays a small part, mostly to help with the appeal to new users who tend to buy on looks rather than functionality. then I can educate them on what's required for good...

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...

Not sure if it's quite what you are after but I've just about finished a fairly conventional 4th axis using one of the harmonic drives and a servo motor, all culled from one of the Korean scrapyards....

It sure is, hard to leave it alone! The tapered ballnose worked better than I expected. It was a ‘cheap’ Chinese one from SpeTool on Amazon so I wasn’t expecting great things, but couldn’t fault it...

Ye aspire is mostly based on wood which is a little less forgiving so any small scollops can be sanded away but in Ali you want a smaller stepover for the best finish.

Difficult to say because...

Isn't this just a question of wording? A misaligned Z axis will not cut square and will need tramming. When I say "misaligned", I mean not moving exactly vertically in either the left/right plane or...

I think the real one's (Spitfire etc) are laminated not one piece . You have made a very good job of it :encouragement:

Nice work!
On the cooling front I found that larger diameter piping (8mm instead of 5mm I think) doubled the flow rate from the same pump. Short restrictions such as the inch-long pieces that...

That's my kind of control box!
There are loads of designs for wooden joints that are designed not to have sharp corners so you can cut then on a CNC machine. Some nice examples at the link below....

With all that is going on at the moment and the effect it is having on everyone's lives, i would just like to point out that i will still be working and able to dispatch orders. there may be delays,...

Awesome work, I am glad to see you have finished with your machine.
Enjoy your cnc mate!

Nice one Andy - good to see actual cutting and know it's possible to get there in the end! Although if its a steep learning curve for you it'll be a mountain for me:)

I'll have a go - means I'll have to measure that one though! Might be a week or two as v.busy at the mo.

I'm trying not to mis-direct this thread (tangent?, what tangent...), but to explain my logic....

If I redraw your schematic (lesson #1, "Eagle" is not good for this)

Hello,

I would like to present the latest addition to my workshop. It’s a 150mm DIY 4th axis (based on a harmonic drive reduction) with an electromagnetic disk brake.

The basis of the project...

PD 14 and PD15 are too low you will get overvolt or over current trips at higher rpm because it cannot get to commanded speed in 2 second or stop spindle in 1 second so it dumps in a load of...

Fusion360 is supplied on a yearly renewable license, you just have to jump through a few hoops to get it renewed for free.

Nice and tidy,good job Andy!

Thanks, Andy

I will try a clean install of Java this evening
... There have been several versions on my Mac over the years, so perhaps there is something unnecessary lurking.

Why 2 switches on each axis if they are traveling.? The point of having traveling switches is to lower the number of switches.

All you do to use 1 switch is set the same input number for each...

+1 I did the exact same thing on my build too!! [emoji85]
