Building machines is definitely not cheap and it's not for everyone. But learning how to operate and build them from scratch is priceless. You really can't put a price on the satisfaction you get from finishing a machine or robot and learning mechanical, electrical, welding, machining, woodworking, and software. Not to mention producing the ideas in your head that don't exist yet.

For my first cnc I went with a cheap aliexpress kit with steppers, controller and frame for 750 euros (ox clone). Got a rattm 1.5 aircooled spindle and vcd for about 250 euros. After a few years I replaced the frame with a diy build with 20mm linear rails and 16mm ballscrews. Added a square tube for torsion stiffness. The upgrade cost about 2500 euros, reusing the steppers, spindle and replaced everything else. The great advantage of steel tubing vs any aluminium extrusion is torsion stiffness.If the printnc was available when I started my cnc journey I'd definitely gone with the printnc! Some excellent points were given in this video! I want to replace the z stepper with a servo but didn't consider a braking system. Thanks for sharing!

Never heard of PrintNC until this video. Interesting how KZfaq works. A lot of good info in this for anyone planning on building a DIY CNC even if they have no interest in the PrintNC. You put alot of work into your videos to make them entertaining. Usually I dislike that and wish people would stop trying to be movie makers and just share the info. But your journey to get where you are I think is like alot of us. We want to build "X" but don't like the price or design of the tool we need to do it so we decide to build it. Usually the designs for CNC on here are not practical. They are usually barely functional and would be good for making something on an occasion and would require as much time maintaining them as operating. On the other end they are so complicated or expensive a person might as well buy one. Oddly enough this design is similar to the one I came up with. I wish you would have made this video 2 years ago..lol. Thanks for the time you put into this and all of the info.

My concrete CNC build is maybe a couple hundred € below that number, it has 3nm closed loop hybrid steppers and 2.2kw spindle, but the work area is half the size.

If you want to build something cheaper than a manufacturer with a fully equipped facility can, then you either need to cut corners, salvage or buy parts at wholesale cost, or delude yourself into thinking your time building it is worth nothing and all you had to pay for was some parts.

Having watched this a few times and with my hypercube evolution derivative running in the background, I'm eager to hear your thoughts on whether you'd make the exact same choice again? My hypercube was probably a mistake. It was a rewarding, but painful experience mostly because I chose a remake, redesigned parts in my first build that spawned additional requirements, and it's clear there are better open source builds now. Doing it again I'd bite the bullet and go voron 2 or like you did with an upgraded ender. Would you do printnc again? Any regrets not just buying one?

So the quality seems not to be that much better and the kind of bearing might also depends on the kind and type of motor of each brand. I doubt that VEVOR only builds in normal ball-bearings in general.

Its a good machine, But I think the only part you do save money on is the metal you brought. Up to the ballscrews, You had spent £720+ So really when you get kits like the Queen Bee Pro Cnc, Actually for the parts you get and the frame its really good value for money going by your video. With that you get liner rails, all that stuff, But it only cost the same amount of money. With free postage, Its hard to argue when you see the individual costs of parts. Just ballscrews, Cable chains, Liner Rails, Aluminum Angle, Still cost hundreds, So the kits actually excellent value. Given me a lot of insight into parts and stuff, I don't think your CNC is expensive, Because it tailored too your needs and must be capable of the jobs you want. So the price point you choose will always depend on the jobs you require, The speed you want them jobs done. Equally you could of spent 2000 it'd still be a great machine, But just less capable than the 4000 version one. In that sense? The price is nonapplicable to your needs its neither cheap or expensive. That is just the cost.. The only CNC machines I think are a rip off? Is mostly shop brought ones certainly for a benchtop. Workbee z1+ I wanted that originally! we're talking £1500+ that is before adding any extras? No liner rails either on that.. Insane pricing. Even when compared to yours.
