I have recently been investing in tools designed so that my hands are never near swirly blades of death every again.

I've acquired a drill press. I now own a stand up belt sander. I would rather handle the wood than the blade.

So, I made my first transition over from analogue to digital.
I've ordered this:
3000mW Blue CNC Laser Engraving Machine

Regular price $499.95
USD $299.95 USD

Ideally I'd like to cut some Roundels.

More ambitious ideas will follow.

So now I need several sets of protective goggles.

I look forward to learning more.

Nice! I wish I had the space for more.

I bought this last year and I love it!

It's a combination belt and spindle sander (the motion is very much like the console's time column,  in both cases ;) )

Nate,

Possibly a daft question but does it cut as well as engrave? I've had my eye out for a decent/affordable one of these for ages

Ditto. Watching thread with interest.
Kind Regards,

It says it does.

This is a different model and it uses a 2.5W Laser to cut acrylic and wood. There is a leaning curve, I understand.


H has better luck here:


The "CNC" in the description suggests it will serve. I may have to upgrade the laser unit, but I don't know that yet.

I'm no expert, but I could well imagine it depends on the thickness of the material.

The lasers I know both cut and engrave, it's just a matter of how strong you set it. A standard laser will typically cut acrylic and wood with a 3mm thickness very well. It can cut deeper, but the problem there is that the "underside" will be larger because the laser usually tends to sort of "curve". If you have any doubts, please do ask.
Oh my giddy aunt!!

No More

The detail lower down on that site seems to say it'll cut 1/6" deep on wood or leather if equipped with a 15W laser.  Surprised that the two are similar density or heat resistance, but OK.
I note that 15W must be in the "ask us about upgrading to a higher powered laser".

Can you get 1000W laser upgrades to cut a Gallifreyan symbol on the moon?!

Just came across this video.

Meet Maslow, the $350 CNC Cutting Machine May 20, 2017 [more like $500 USD $12 shipping US, $60 worldwide]


interesting....

This may be a later purchase.

So, I have a thought: If I buy additional rail extensions, I could feasibly have a 4'x8' working space.

I could adapt the easel idea for CNC kit I have already ordered.

Now I need to find out if these rails can be purchased.

Had to track down Kevin's Roundel stl file. Thanks mate.  ;)

Everything is up on my google drive.  STL files and FreeCAD files

https://drive.google.com/drive/folders/0B9wuQYOPzaXcQjIwZGgxTG4tMm8?usp=sharing

BTW, I have also updated the Shapeways shop with the new STL files.  I have a new former on order and will update everyone on how well it matches as soon as I get it.

I uploaded the thinnest version of the full roundel STL to my Google drive "FULL THINNER ROUNDEL KEVIN FINAL.stl".  However, be advised that this version does not take into consideration the most recent changes to the former.  I never created a full roundel render of the most recent former profile.


If I'm going to make roundels/Doctor Who Stuff - Time to track down some files.

So I ordered the product through Pod Computers. My mate Arpad (R-Pod) tells me there is a package waiting. So we'll go to our local watering hole after work. Taco Tuesday. I will have the package after that.

So I started watching youtube reviews in order to understand the product better. There are some 3d printed parts that will improve the mechanics

https://www.thingiverse.com/thing:3258506
https://www.thingiverse.com/thing:3639200

and a few inexpensive upgrades of varying degrees of difficulty to improve the machine. https://shop.watterott.com/SilentStepStick-TMC2130-V2

There are different types of lasers. Diode Lasers are weaker but less expensive, there are CO2 lasers 60W, there are Fiber Lasers (The budget of a small country.)

It is recommended to upgrade your eye protective laser glasses to something more robust.
