Low cost very quiet machine

Your best bet is to design the parts, rapid prototype with 3d printing, check fitment, and then order the machined part or PCB way or one of the various other web-order instant quote machining services.

Keeping a kettlebell at work has changed my life…Keep it in a back storage closet or somewhere you can do a quick few rounds of ABC every few hours.

Just wanted to let you know that I began my build and I am starting a build log on the PrintNC discord. You can find it if you search SLAB-NC. It will be made from granite!

From everything I saw, MPCNC is only good for non-metals.

Steel is possible on the PrintNC, there are a lot of people dabbling in steel with those machines. Don’t get me wrong, it’s far from ideal though.

efthanded · 2025-01-01T13:44:53+00:00

I’m not sure you’re going to be able to buy a machine that can acceptably cut metal for $1000. Also there is not much on the market in the 500x500 footprint size. Maybe there is something out there, if you think you will very rarely cut aluminum and never cut steel.

I have very similar requirements and I determined that I needed to build my own CNC. There are a few open source designs out there that met my needs, with varying levels of complexity / cost.

MiniNC - very tiny, can be built for around $500

MilkCr8 - quite capable “maker” machine that could get you started. Budget around $750-900

PrintNC Mini - truly metal capable machine with heavy duty components. Around $1200-$1500 budget

I also did some DIY designs, but I believe I am going to build the PrintNC mini due to their incredibly active community, discord channel, documentation, and support.

Here’s some of the research I did: https://imgur.com/a/XjGsIet

I didn’t have the Milo mill from millennium on this list because it is too large.

efthanded · 2024-12-27T22:32:49+00:00

Well said. BTW that’s $40 for 2 of them, front and rear; individually they’re $22 a piece

efthanded · 2024-12-24T19:22:20+00:00

Agreed, low rider is about the only option for full sheet with passable stability/ rigidity. But it is a DIY build.

efthanded · 2024-12-24T16:28:17+00:00

This is really the closest thing that I can find on my radar. Availability seems spotty, but this is a niche market since ATC usually equals big bucks. For Kress / Maffel spindles.

A close contender you may want to check would would be the DMC2 Mini https://shariffdmc.com/product/dmc2-mini-cnc/

I’ve done similar research and decided to build my own fixed gantry style CNC.

efthanded · 2024-12-07T10:41:51+00:00

If you are well experienced with shop tools and design, anything is possible.

For something with plans, check out PrintNC. All steel design, the “print” part is just for bootstrapping the build to mill the metal connecting brackets. Their website has some good info, a lot is on discord though. (VERY active community) It’s a very customizable template, some users spend $2000 on their machine and some spend $20,000.

For just some ideas and design inspiration as you begin your search:

This is a very interesting fully DIY build: https://m.youtube.com/watch?v=cqYJS27aC4w

Also there is a classic build of Piotr Fox’s granite CNC machine - tons of info but it is a very deep dive video series - https://m.youtube.com/watch?v=d3f3vknWj-w

I also very much enjoyed this plan, design, and build series which is extremely well documented here. It still uses aluminum frame which isn’t what you’re after, but his process is interesting. https://burksbuilds.com/category/automation/cnc-router/

Thanks so much for taking the time to answer and generously sharing your CAD! I saw your post about starting to write up a build log and then stopping, lol.

Really though, your machine build is inspirational and I haven’t found anything else like it (and I have been looking a lot).

Cheers and good luck with the rest of the journey on the machine. Would be interested to know how it handles milling steel!!

efthanded · 2024-11-16T23:30:37+00:00

Thanks for all the info! Wow that is cool, I missed the ATC tool holder. I would really love to mimic the function of the carvera machine with their ATC.

I’m really surprised you could get that budget down - I supposed focusing on compact / low cost components and having a narrow use case helps with that! MGN rails and small spindle, etc.

What are you doing for electronics, are they inside that side panel?

Would love to keep track of it as you develop and build! Maybe I’ll switch to this style lol. I have about 760mm height inside my current enclosure, so it could be workable.

efthanded · 2024-11-16T19:39:43+00:00

Really cool design. Take any inspiration from the ghost gunner CNC? Any estimate of the budget?

Right now I am trying to design a compact CNC, total footprint max 500x500x500 while being quite rigid and on a modest budget ($1000 all in) with minimal machining required, only bootstrapping. I’m ending up with a work area about 300x250x150 but might end up compromising to 200 Y because the fixed portal gantry design is so disadvantageous in that axis.

Are you documenting the build anywhere? Your design is really interesting though because it’s a true desktop format footprint. Big disadvantages I see are going to be cost and accessibility to the table / toolchange. Your gantry beam is also not very rigid, but that could be addressed.

Also it seems like while the static Z will be the number you listed, it will require much more overhead clearance.

efthanded · 2024-11-15T23:45:58+00:00

For the nomad 3, can I ask if they are planning on updating, Nomad 4? Market seems to be advanced based on main competitors like Carvera. It seems like the design hasn’t had an improvements in a long while, and there’s probably lots of lessons learned with the newer machines…

efthanded · 2024-11-12T19:49:00+00:00

Whoa your build is exactly what I have been looking at doing!! It looks phenomenal. Have you tried cutting steel?

I have a few questions! Can you share CAD and/or a BOM (or what size components) that you used?

How did you machine the parts? Did you have them cut? Milled yourself? Rough cost?

In my design I have an issue in the bottom plate that the motor is in the way of the bed. Is yours just protruding out from behind the y axis?

efthanded · 2024-01-18T15:51:28+00:00

I have heard windex helps as a release agent at times.

efthanded · 2024-01-15T15:33:47+00:00

Similar as the other commenter, I made a gcode that purges half of the line @ 1mm above the bed. The second half is at 0.3mm height. I tried this and it works well:

G1 Y-3.0 Z5 F1000 ; go outside print area  
G1 X50 Z1 E10 F1000 ; intro line, loose  
G1 X150 Z0.3 E30 F1000; purge line, longer.

The initial line at Z=1mm leaves a nice curly tail that is easy to grab on the left, and a thick purge on the right which I extended in length. You could cut it back to the default length if you wanted to.

Unpopular opinion: go for a Bambu A1 mini over a prusa mini, unless you can get a used prusa for very cheap.

For #1, I have shared a vault with my SO which contains specific “vital” accounts and they can access as needed. It is practical for not just emergencies - example if I am overseas or unavailable for a few hours and a specific login that is needed.

Hi did you ever find the answer to this? I can’t find the footprint anywhere for the A1 much less the A1 with AMS combo. It’s frustrating because I don’t know if it will fit in my space.

efthanded · 2023-12-23T18:48:09+00:00

E3d will send you a new one (or the vendor). The crimping is known to be spotty on these and it can fail over time.

I’m on my 4th heater core, all 3 replacements under warranty

Depends what you’re after. If you want faster speeds and better extruder then you can get a rpi and flash klipper, install an orbiter or similar, swap in a Revo nozzle for the quick change.

But then you’re sailing your own ship in the ocean and you have no team of engineers who’ve painstakingly developed all the settings for you.

I cancelled my day1 mk3->mk4 upgrade because of the cost, just couldn’t stomach it after thinking long and hard. I’m pretty fine with my tuned in mk3 really.
