Are you planning to publish the basic CAD? Using the t-slot extrusion as you have should make it easier to build a simple enclosure, somebody in the community might end up giving it a go.
The way the X and Y motor stick out makes it a bit footprint-inefficient, which could be resolved by adding a belt and flipping the motors 180º, but at that point it’s probably becoming a bit overdesigned for its primary use case.
Yes, the CAD is coming. Just wanting to further validate the complete machine and ensure the part designs have solidified enough before sharing.
The motors sticking out is an issue. One thought i had was due to our cable management, someone could easily design a small window-cutout for the X motor to stick through as it goes back and forth. It technically wouldn’t be within the enclosure, but could allow for the machien to be almost fully enclosed.
As for the Y’s… they could also have cutouts to allow the motors to stick through the rear wall. Of course for tiling operations, it’s good to have a horizontal swinging door that could come up whenever passing-through parts are required.
Dual spindle head on future larger model like 4x8 or 5x10
Old thread but I joined the forum just to express my interest in this. I already have the large majority of the items needed to build this and would simply need the right length ball screws, linear rails, Z carriage, and lastly the gantry plates for each side.
Sounds like you want the mechanics only
This would work but my current setup is built on a 40 series extrusion with 4080 on the Y rails and the cross members and table supports all being 8080….I have so much of the stuff laying around I would feel silly buying more. Its really only odds and ends that I would need to make a full machine.
Edit: I probably could figure it all out to build my own machine but if one supplier had already figured it out and could supply it why go through all of the extra work or redoing all of that.
I was just going off your list where it looks like you had the rails, motors, wires and the controller and showing you a skeleton is available.
Finding a one stop shop to complete what you have on hand… well good luck
I know wishful thinking, thank you!
How long until 4x8 version ?
It’ll involve a redesign because to get a ball screw 8’ long is cost prohibitive. Not only does it need to be longer, but they need to be thicker too to counter the whip. My buddy has a 4x8 with ball screws, and they’re about as thick as my wrist.
It’s not as easy as just doubling the rails up.
Granted, I think going the DIY route for building your own CNC, or anything else, is a fantastic hobby unto itself and can be a very rewarding journey that easily consumes many months of time. But it wasn’t until after assembling my Dominator Pro that I fully realized that there is so much more to creating a functioning CNC machine than I thought.
PwnCNC has spent a tremendous amount of time sourcing the many parts that make up a fully functioning CNC machine from all the necessary suppliers. These “odds and ends” as you called them includes custom machined, heavy gauge aluminum plates and ball screw bearing mounts, along with the careful attention to fine details such as the exact sizes and lengths for every single component. Then there is all the hardware such as machine screws, T-nuts, cable drag chains, the controller mount, and they even include an undercarriage LED strip. Follow that with the time they spent on assembly, calibration and testing, and you begin to appreciate how much work they have done.
Also, when you consider that this is the heaviest machine by weight in its class, or in other words, the sturdiest and most rigid “hobby” level CNC which, IMO, actually crosses into light to medium industrial territory, and that it is production ready at around $4K, I think it becomes very challenging to compare it with anything else on the market.
I fully agree which is mostly why I havent gone that far. Ill keep my hopes that maybe down the road more components will be available individually or as an even smaller option to the mechanics only which will allow me to use more of what I already have.
In the meantime saving my pennies to get the full kit. 
I find myself wishing my dominator pro was faster in cuts and rapid movements. I adjusted some of the speeds in the Masso till I hit the ball screw limits for vibration / whip and then backed it down and tested. After I few test I found consistent slightly increased speeds.

I agree with you. I find the max speed of 200 ipm disappointing or a CNC that is built like a tank, It should be able to do higher speeds. If I understand right the 1605 Ball screw is the limitation and understand why Daniel chose to use it. It is good for how he would be using it. But it shouldn’t be limited to it. I’m definitely not a expert, but I can’t help believe that there are not other ways to maintain “ Precision and Reliability” and increase the Max speeds at the same time. This 200 ipm is the same max speed I have on my Nextwave Shark HD520.
I cut a lot parts out of MDO and the spindle needs to travel between a lot of parts on one sheet to start a new cut. It really slows everything down. Especially when using a roughing bit that can hog out a lot of material and will never get close to the bits capabilities.
Don’t get me wrong I love my Dominator, but if there is anything I do not like about it, it is the 200 ipm limitation.
