Andy,

Welcome aboard. The ideas you implement are interesting but again you need to specify your target market. I can see you doing well on kickstarter actually. Especially with the 3D printing crowd.

There is a huge "maker" movement in the US and Canada that are looking to make craft type stuff. Anything more and you start needing serious machines and not toys.

Not being dismissive of your machine here, just trying to help:

Your machine will perform "OK" when cutting light, small jobs with the drawback of being loud and slow. In the real world time is money so for me, along with the others above, your machine is cute but a toy.

If you want to lightly engrave plastic, cigarette cases or route PCB's then I think you may have a winner if you can make it for less than $200 and include your own software that has bells and whistles like the lightforge laser machine and that stupid pancake printer.

Either way, should you wish to sell it in Europe, make sure you use ROSHH materials and read about CE marking it.

Best regards

George
