This box is designed to fit my external driver board for the original Prusa MK2/MK2s printers.

It's is an external stepper driver board for X and Y stepper motors of the original Prusa MK2/MK2S printers. It allows usage of TMC2100 (Silent Step Stick and similar) drivers, so your printer will become a lot quieter and much smoother due to the 256 step interpolation (same as on the MK3).

UPDATE!! 28.04.2018
I made 6mm shorter version of the box, because it turned out I used custom front and rear brackets for the Y axis and they are taller than the original ones. So If you're still using original MK2S parts use the SHORTER VERSION of the box!

More information about the board here:



You will need some supports to print the box.
I've included versions without the voltmeter and without the Noctua fan.
Noctua fan should be 40x40x10, 12V.

would really like to order one if the boards but i ( like many others) can register in order to make and order.

do you provide the un complied firmware too? as i need to adjust the motor currents for my MK2

Hi, sorry for the late answer, I'm preparing second batch with upgraded version which will be available very soon. It will work with the official firmware and will support all upgrades for the MK2S. Please follow my blog if you want to get notified when they're in stock again.

Been running this for a few days now. Good job!

Yup definitely running much much quieter so thanks for this modification.

I think that maybe the X and Y motors are now running a little on the hot side, although it's quite possible that they were running hot before the mod and I just didn't notice. I will keep an eye on it.

They can get very hot, because of the new drivers. Their algorhyth is just different. I have mine printing all the time without any problems. MK3 motors also get very hot, so no worries :)

I can confirm that this works with the Multi Material upgrade since I have received and installed the board.

Great idea! But I assume that it will not work with the MMU?

Thanks! It should be working fine with MMU, but I don't have the upgrade, so I'll have someone to test it soon. I'll announce it when I have more info.

The MMU uses the connector just right to P1/P2 (on the top), labelled P3. Does this extension use another connector?

MMU ises just half of that connector. My board uses two pins on the other half, so no problem :)
