the product is well worth the price

A couple of small QC hiccups but the customer service to remedy the issues was fantastic! I’ll definitely be a repeat customer!
Robert (verified owner) –
It’s definitely a sturdy rigid machine. I do run into errors though I am trying to work out
Josh (verified owner) –
works well

No problems

Vertically adjustable legs would be great for uneven/sloped floors.

Poor, incomplete, dated instructions. Missing parts (4 bolts for leveling pads – sent email regarding this – no response, no apology). Poor customer service. Faulty SLB-EXT board took a week to get here (should have been sent overnight). No instructions as to how to reinstall and to look out for changed parameters like spindle speed – first carve began without spindle rotating – broke $60 bit). This has caused serious production delays on our end. New SLB solved connectivity but spindle does not come on. Called and left a message for assistance. No response. Sent email. No response. Very disappointing. SLB-EXT case too tight. All the cables have to be jammed in to get the clear cover to close. Wire management lacking.

The machine is a game changer for me. Some updates I think you should seriously consider is diagonal bracing for the 4 sides. Also some simple 3d printed holders for the zero plate and wrenches.

In simple terms – exactly what I was looking for! The size is perfect for the majority of my projects, with the ability to tile on a machine like this and cut a full 8′ x 4′ sheet is perfect.
The simplicity of assembly is amazing (not actually that difficult to build alone). The aluminum extrusions provide a solid base to customize and build out a solid storage or other below table solution. I was able to design and integrate a custom table extension, front and back for the previously mentioned 8′ tiling options. As well as include multiple large drawer storage and flat stack solutions.
I opted for both the 1.5kW spindle and G-sender computer options, hands down totally worth it! I appreciate the flexibility in mounting and locating the control computer. Ended up locating the CNC sideways along my back wall for plenty of extension room front and back of the machine and mounted the swing arm and computer to the side wall (not on the machine leg per typical). This provides a ton of versatility I was looking for.
Setup and configuration was far simpler than expected, well thought out design and engineering for this price point of a CNC with this level of capabilities. User interface of the G-sender control software, hands down, second to none for a new user or more than powerful enough for a veteran CNC shop.
One upgrade I would appreciate on the software side would be the outliner function. The ability to have this function is amazing and is very useful for visual confirmation of clearances, cut area and potential issues. The current execution of this function could use an upgrade in my opinion.
I would love to see two options for the outliner function
1 – Total project scope area outline
– Actually outline the true boundary of the project outer most extents.
– currently the outline follows the tool path to the furthest extents and cuts the corner back to 0,0,0 at the end of the tool path.
– Update to have the tool follow the actual max extents of the total cut area extents.
2 – individual boundary outline
– Run a single high-speed pass outlining every exterior boundary line
– Think flat pack cabinet project with multiple nested objects, run the outline to understand where you could locate a screw or hold town or just understand what you laid out on the board will actually do what you expect the CNC to do.
High points:
– Machine is great!
– Quality is high (as expected based on research of the company and product reviews)
– Performance is amazing (especially at this price point)
– Easy and intuitive to understand and use
Basically, exactly what I’ve been looking for and waiting to hit the market for the past several years!
Thanks for an amazing machine and keep innovating!

Easy to put together. Forgot to take the cable carrier out of the X axis extrusion before mounting. It’s difficult for an old man to lift it once the Z axis is mounted, but that was my fault. Everything else went fine. This is a solid machine and I am very pleased.

It feels like this machine is half finished. Some parts are well designed and well built, and others feel like afterthoughts or parts that were half-done when they decided to launch. It works, but there’s plenty of places where you’ll be assembling and go “…they did it like that? was it Friday afternoon or something?”

Great product, very high quality!

So far so good. Started with an xcarve upgraded to Onefinity, and now upgraded to AltMill. Loving the rigidity. This thing is impressive. I did have some problems with customs during delivery. CS helped more than required. Great experience. Thanks guys. Looking forward to what you guys have in the future

This was my first CNC and I learned a lot. The online support tools are great, but I feel could improve with a better search function. Also, I mangled a few pieces when I first started to move the gantry. Just needed a little more details on proper startup routine. Other than that, this is a really well designed and built tool.

Love the everything about the machine has been wonderful setting and learning as a new CNCer.
Konstantinos Barmpounis (verified owner) –
The best CNC in the prosumer category—nothing else comes close. Fast and rigid and fully capable of production work. I would like to see some minor improvements in the future but considering the price of the machine this is already close to perfection.
Jack Scott (verified owner) –
An excellent CNC.
Matt Q. (verified owner) –
The set up of the machine was fairly time consuming (about 10 hours) but pretty easy if you’re good at fallowing instructions. Felt the price point was great for the product I received.

I shopped around and liked this CNC and it’s price.
