Z axis can be easily blocked with "dummy nut" loaded with spring which is released with electomagnet when the machine (or only Z axis) is on.

Material for dummy nut is usually nylon or HDPE, therefore no worries for wear.



Congratulations for CF mill. I am impressed. Professional job.

Lovely work there Zeeflyboy. A machine has to function but no harm in making it look nice along the way!

I've hit a slow spot on my build and other commitments need sorting so looks like you are going to finish well before me. Good progress keep it up.

Hi Zeeflyboy
did you calculate? How much did you pay for everything?

Sorry, qmarjov - I don't yet have numbers to share for cost. I will do a rough estimate nearer the end though.

As you guys may have noticed, not much has happened last month or two. What with christmas and work commitments I haven't had time to do anything substantial on the project... The extra work related stuff should abate mid february and that is when I expect to pick this project back up more in earnest, though I may continue to do little bits and bobs along the way.

The reason for this post is that I just got a cool new toy to play with and thought it was too cool not to share the results.

When I say "I", I actually bought this for the wife so she could start a little home business to allow her to turn her hobby into a little side income stream. Of course, I get to play with it so I'm just going to count it as one of my toys!

So what is this new toy? Why a 45w CO2 laser of course!

We've actually done quite a few little test projects over the last day or two (including some cool stuff like etching slate coasters) to test out the machine and get the wife acquainted with operating it. But today I thought I'd have a little play with the sort of thing I actually want to use it for:

I tweaked my Logo design and did a quick test in wood to see how it looks:

Decided it looked nice, so went hunting down some anodised aluminium to try etching.... only thing I had to hand were the thorlabs angle brackets. I popped it and and had a guess at some numbers, came out beautifully! I had to remove the honeycomb tray as the brackets are a little thick to sit on top of that, so that is why the bracket is sat on some chopping boards. This job took about 4 minutes to run through.

I'm pretty ecstatic with the result there.... definitely opens up some new possibilities in terms of finishing items I make once I've got the anodising rig setup and working.

Aaaaanyway, back to real life work! Sad times.

Nice logo and the laser you bought is a good move for someone who wants to start a home business!

Well we shall see how it works out, I'm not expecting to be able to retire any time soon but I'm hoping she can make enough money to pay off the expense of the machine/maintenance and generate a little income from something she enjoys doing. Obviously this stuff is becoming more and more accessible so there are a lot of options out there for people looking for bespoke laser created items but I do feel its the sort of low volume thing that fits a "cottage industry" type operation rather well. I think going around and getting some tie-ins with local wedding dress shops and flower shops etc would be a good way of generating some business in a crowded online market.

But more importantly, I get to play with a frikkin laser!

what size cutting area has it got?

20"x11.5" I believe, although in theory as long as the material isn't too thick (the slots are quite narrow) you can use the passthrough slots to feed a longer piece of material 20" wide through the machine though I haven't tried obviously.

I believe the plan eventually is for it to take care of the passthrough automagically using the cameras for alignment and continuation of the pattern but that isn't available yet in the beta software. I believe it can be achieved manually you just need some way of indexing and aligning.

That's very cool..! Any links to the laser you bought? What are you doing for extraction? I ask because the ones I've used in the past have had pretty expensive filtration set-ups attached to 'em - and given the smoke they generated on some of the jobs they really needed them too...

Excellent work though, man and best of luck to your wife in her new creative endeavours..!

Would like to know what machine that is.

I have the K40 and the steps are quite visible when engraving anodized aluminum.

Itís a Glowforge Pro... finally arrived after buying one during the Kickstarter over 2 years ago. Thankfully that was at 50% the price that they are currently asking!

I have to say I thought that despite the marketing blurb of custom tubes etc it would be a mediocre laser but with an easy user interface for the non-technical missus to get to grips with, but first impressions are that it is actually a high quality bit of kit capable of some stunningly detailed results AND pretty easy to use.

Extraction wise, they have some fancy activated charcoal and hepa filter unit thingy but that is even more delayed than the laser itself and wonít be ready until the summer. It has pretty effective (and noisy) extraction fans and a hose connector on the back for drier hose. Currently that just gets shoved out the window to kill the squirrels.

Just loaded YouTube and the newest video was LinusTechTips showing off the Glowforge xD

Looks alright. And yes it is not cheap.
Interested in the filter. New workshop does not have extraction and I am not allowed to bore a 4" hole in the wall. Not even for the tumble dryer -_-

ZeeFlyBoy would you be willing to share the fusion 360 files ?
This thing is truly amazing in every aspect!!!!!!!!!!!!!!!!

Haven't made any decisions on that yet, although I've been asked a few times.

I need to wait until I've got it all together to check for any design flaws or things that could just blatantly be done better before deciding about that... I've already had a few little re-designs and tweaks along the way which would have wasted people's time and materials had I already made the files available.

I do hope to be able to get back to this machine in about a month once this stuff at work is sorted out, so hopefully it'll only be a few months or so until it's all done.

Word of advice don't cut PVC, the wife will die and more importantly the fumes will also damage the machine ;)

When you drill, cut or melt it with a laser lol the chlorine is released into the air. Chlorine gas was used as a nerve agent before mustard gas in WW1 it didn't work very well because charcoal filters it effectively but without the gas mask it's pretty affective.

How do I know this I drilled out 100 or so PVC pipes in an enclosed space and learnt a valuable lesson that day as well as taking 10 years off my life lol. But laser cutting releases a lot lot more gas then drilling.

yeah, not just PVC but any chlorinated plastic can produce chlorine gas when lasered... Apparently plenty of things to be careful about cutting due to what's released.

Thanks Zeeflyboy for the response on the files. I will be watching till the end!!! I love the design. I would just scale it up to a (work area of 610mm x 915mm). And Specifically for aluminum/Brass cutting. I cannot believe the results you are getting with your current CNC.
