Rook 2020 Scalable MK1

MK2 is out! 

Rook 2020 Scalable MK1

This is my mod for the Rook 2020 to make it fully scalable to any size.
(within reason, there is a limit to what the 2020 extrusions can do..)
This also adds a triple belted geared Z-axis
 

To determine your extrusion and rail lenghts, add 150mm to your bed-size and 100mm to your desired Z-height

This uses corner-cubes, not 3-way joints!

For for a 200x200x200 build volume, your extrusions would be 350x350 for top and bottom frame and 300 for Z.

X-axis extrusion and rail is 50mm shorter than your top frame.

Please note that this scale does give you a lot of extra movement on both X and Y, this is meant to accommodate mods like klicky, wipe-brushes, nozzle-probes etc.

Bed is made up of 2x extrusions the same length as your top frame and 2x the same as your top-frame - 150mm.
 

Here is a Frame Calculator to help you find your frame size

Supports MGN9C for the Z axis and X axis, and MGN12C for Y-axis.
In theory, the X axis can use any rail to adapt to your desired printhead.

New on the MK1 update is a geared Z axis. Ive made 2 versions, one with 20t pulleys and one with 12t pulleys. 20t pulleys should be fine for most builds up to the 250x250 bed size, any larger and I would go with 12t.

Remember to set your rotation distance and gearing it the config!

This supports all the Rook and Rook 2020 toolheads like the Sentinel and the Rookery and all of its derivatives. You mighty want to look in the Official Rook mod collections to see if you find something you like.

I highly recommend you use Said's Belt tensioner. It really helps to get the belts nice and tight.

Here is a link to my BOM, please be aware, this is a scalable design and adaptation may be required, so get more fasteners than you think you need.
 
Parts that needs to be printed more than once is marked, use only the M4 or M5 idler versions according to your hardware, and note the 20t or 12t pulley parts.

Just a small note, this printer is the perfect place to use multiple MCU's if you have them lying around. only X/Y motors need sensorless homing, so you can run the 3 Z motors on most boards. Im running this on a SKR 1.4 and a Ender 3 board. Big bonus is the extra outputs for lights, fans, heaters etc.

Want to use the parts from your Ender-3? have a look at THIS

(Printer in picture is a 350x350x400 printvolume design.)

Configs can be found on my github, however, they must be considered examples, as this design is extremely part-dependent!

Big thank you to my beta-testers for their work!
