Hi everyone!
About 3 years ago I started into 3D printing with a P3Steel Toolson MK2. I still use it as of today, and recently, I printed a few of stuff for the COVID-19 medical teams. While my printer can produce quiet nice result, it is a bit small, and a bit slow, so I figured I'd make a new one :)
After much reading, I decided to go with the coreXY style, and took a good reading at this great blog: [drmrehorst.blogspot.com].
I see that the author is on the forum, so if you come in this topic, thanks a lot for putting all this information out!
So, about the project. First of all, the goals I'd like to achieve:
- Bed of around 400mmx400mm, with 500mm linear rails for motion
- Smallest footprint possible
- Dual extrusion, with a chimera and Bowden setup
- Head as light as possible in order to be able to crank up the speed.
- I'd like to have a cost less than 700€ if possible, and no more then 1000€ in all cases
The main point of the construction will be:
- 3mm aluminimum laser cut frame (or steel if needed)
- 500mm linear rails
- As much metal as possible for the moving part
- I think (but I'm not entirely sure about that) about a 3 point fixation for the Z axis, with one motor and a belt
At the moment, I just started the design, with the XY carriage and motor mount. Here is an overview:

I'll use bearings staks on top of each other, but I'll use 624ZZ instead of 608ZZ as they are smaller, but the same radius than the GT2 20 tooth belt pulley, so I should be fine regarding the bending radius:

The alignment is calculated so that the important segment are parallels.
I can only put a 6mm belt, but maybe I'll make a washer between the ball bearings, or add a third, thin one, to get the 9mm.
I haven't included the screws yet, but the bearings will be held in place with a M4x30 screw, and I will use 4 screws that goes from the top to the rails to fix everything in place

I know it is early work, but do you already see some mistakes in my construction? Any suggestions?
