Test print – Clone vs Original

My clone is already fully working, I’ve made some tests.

I didn’t wrote that before, but I’ve replaced Z axis stepper motors with chinese ones with integrated trapezoidal Tr8x8 screws, as because of the coupler the Z axis was unable to go low enough to print. I strongly recommend to also do that, otherwise You can have similar problem. It will also help to avoid wobbles, which are mostly caused by the couplers.

The chinese motors which I’ve used are with screws 300mm length, and its enough to drive the Z axis to the top, even if they are not long enough to be over the Z-tops.

I’ve put the printer on karimata (joga mat), to (mostly) reduce noise.


On the chinese MK3 heatbed there is directly sticked the cheapest adhesive surface, I found that at my local reseller.

I didnt wrote anything yet about mounting the heatbed, but its really a easy task, just put the MK3 on plywood, use 4 M3 screws and heatbed springs, and using self-locking M3 nuts – screw it.

Eventually, the test print: (3DBenchy by CreativeTools)

One of the prints is from the Clone, and the other one is from Original Prusa i3 MK2S.

Filament used: ESUN PLA+ Green
Layer height: 0.2mm

Are you able to guess which print are from which printer? There are small details which should tell you that.

I’ve made also a short video from print on the MK2 Clone.

I am really surprised with the print quality from this clone, I wasn’t expecting that it will print so good.

Soon I will finish the Bill of materials, with a links to stores where you can buy all of the parts to build a MK2 Clone.
