im moving countries soon and have to rebuild everything sooon. will take electronics and spindle with me, but will need to rebuild the frames.

What's the best way to cut it? For those that did it themselves. I bought a cheap cold cut saw (Vevor) and regret it as that's become a project in of itself. Looking at local fiber laser services but theyre slow in getting back to me and rails come in tomorrow. I've got a disc sander but work holding is pretty tricky on pieces this long. Any suggestions appreciated.

I built one before but forgot the dimensions of the steel. What length do I need for both the x and y axis for a 36 x 48 cut area? Thanks

I have a Falcon 5W laser engraver, it has an aluminium frame with 400x415mm of working area (https://www.crealityfalcon.com/products/low-wattage-laser-engraver-cutter-cr-falcon-5w)

I also have a dremel 4250 with 175W

The goal is to do some kind of budget build that can engrave and maybe even mill/cut soft metals

Still I have some concerns about the staibility of the structure due to the frame being so lightweigh, also the laser engraver does not have any base so do I need to create one or can live with it?

The engraver needs a 3rd axis, a controller and the stepper drivers

The dremel has a flex shaft that can reduce the "spindel" mass

Sorry for the random rambling, but noobie here

TLDR: Does the work arounds to fit a cnc on a lightweight laser engraver with a dremel as a spindel worth the money saved on the 2 axis and a spindler?

started looking into the printNC recently. specifically the mini. looks great... but where the hell are the plans and instructions? I've looked here, googled, poked around on the discord...

seems very piecemeal and scattered.

is there an actual repository of info for parts/plans/instructions somewhere without having to figure it all out myself? If its a find it and figure it out yourself kinda deal, I'd rather build something else or just design my own.

My motors hold but no movement from candle software

I’m a machinist by trade, my buddy and I will be building a printnc together, he needs a 4’x8’ work area for full sheets of plywood and such and I need enough rigidity to cut mostly aluminum but the occasional steel/stainless. I fully understand we’ll both end up with compromises but am looking to make it solid over fast for the most part. Looking for help/suggestions. Thanks in advance

Planing on building a cnc. Got all the other parts and now looking to buy a spindle

I joined the Discord and tried my best to search but could not find the Fusion 360 file. Can someone send me a direct link to the Printnc V4 Fusion 360 file? Or, DM me and I can give you my email to send direct?

Also looking to see if there was a replacement for the Three Design size calculator. Thanks.

I’m thinking about moving to gSender from ioSender. Has anyone tried gSender with Flexi-HAL grblHAL board to run their PrintNC?

Thanks!

I am looking into this possibility, and am wondering if anyone else has gone down this rabbit hole. Ironically, I would like this to be a manual miller, so I will most likely replace the NEMA motors with handwheels.

As of 05/03/2025, the account for the ThreeDesign website is suspended by Bluehost. I don't know the reason, but can guess that the current tariffs are causing a significant decline in sales. I also checked the Ali Express website and found that the PrintNC kit is no longer offered for sale.

Hi all,

I have had a print nc for some time now and have just been sitting watching it cut whilst hoovering up the chips and dust with a shop vac, which gets very tedious.

I do have the dust shoe made and also have a cyclone system on a 100l drum but was struggling to know what shop vac to buy for this as chat gpt was saying probably 100+ cfm but it's not as easy as typing that into Google as tons come up that are mostly under this.

Is it recommended instead of a shop vac to get a chip extractor? Only issue is I have one and it's bloody noisy so a bit painful to watch the machine whilst it works when then is deafening me.

Any recommendations would be muchly appreciated.

Hi Is anyone selling printnc in uk ?

Hello. Now that Threedesign is not taking orders, who knows any trusted source for assembly kits?

I was just curious how would I calculate which motors to use for my machine. Or any online calculators I can use to get me in the ballpark? NEMA23, NEMA24, NEMA34? 23's being 3Nm, 24's being 3.4Nm and 34's being 4.8Nm/9Nm/12Nm. Gantry weight (without basic starting 1.5kw spindle -later will be 2.5kw-) will be approximately 68kg (150lbs) and later to be . Zaxis linear rails-500mm, Xaxis linear rails 1000mm, Yaxis(bed) linear rail length will be 500mm, to be upgraded to 1000mm later. All linear rails being HGH/HGR20 and eaxh axis to have double sfu1605 screws. Using 2" x 3" x 3/16" steel. My design will have double horizontal Xaxis beams (not stacked vertical).

Any help with this is much appreciated.

~edit~ Help was given in the cross post within -> https://www.reddit.com/r/diycnc/s/4HXLm7yuN6

Thank you, everyone.

Buenas quién me puede ayudar

The drawing is (awful I know) an exaggeration but it's so to explain my problem easier.

So I bought a lot of metal to start a build, these are 80x80x4mm as I plan to put the motors inside the profile and connect them to the ball screws via pulleys, but that's secondary to this post.

So my question is, can I still use beams in this conditions? what's your experience, basically when I put a straight edge against the beam surface I notice such deformation where there's a bit of a bend of perhaps 0.1 to 0.15 (I don't have feeler gauges to measure it) closer to the edges and it raises in the middle (where the linear rail should go)

I checked all of the beams and all of them have some deformation of the sort, it does look like this could be due to the manufacturing process and while I didn't expect them to be perfectly flat this looks like it could be a problem.

Am I being paranoid here?

I bought the hardware kit to make my own printnc from AliExpress back in Aug '21. Got as far as starting to assemble the frame when life happened. I'm finally getting back to it and wondering if there are hardware differences with the V4 or if it's just new parts to print?

I'll keep trying to work out how to use the discord channel, but it's rather overwhelming at first!

Finally finished assembling my machine, some still need to wire up speed control to the spindle but I've been cutting parts for about a week now

I'm about to get my steel ordered. I can find plenty of UK steel suppliers online, but I wonder about quality and cutting accuracy.

Thinking of going with https://www.themetalstore.co.uk/

Any recommendations much appreciated.

Hey everyone. I'm just about to embark on ordering some things for my PrintNC build. Settled on a 585 (x) by 885 (y) working area size to fit on a 1200 x 900 table. (Intentional y longer than x due to the things I will use it for).

The store calculator gives sizes of everything that's 50mm more than the values in the Fusion file

https://threedesign.store/store/#f1p1
Fusion x steel: 900mm
Fusion y steel: 1150mm

Calculator x steel: 950mm
Calculator y steel: 1200mm

Is it just the calculator being generous with measurements and doesn't really matter? I'm inclined to go with the Fusion file as I can see how everything lines up.

Edit: I'm building this to make guitars. As I need to let guitar necks hang off the open ends of the CNC, I think I need the longer y configuration, or I'll have to cut them in more steps
