MK4 Control panel:

The new MK4′ diplay involves new printed parts for integration in Prusabox.
As soon as we have CAD files of display, we will release new mounting parts.
We plan to release :
We plan to release :
- Basic mounting parts to assemble MK4 control panel on the front of our straight control panel.
- Mounting bracket that will fit to Modular Control Panel.
MK4 Dimensions:

Nextruder is a little bit bigger:
A: With Nextruder, X axis is 455mm long, therefore PrusaBox MK3 needs to be enlarge on each side.
B: Nextruder is higher on about 30-40mm. It is an issue when Z is in top position because at this moment we have 40mm gap on MK3 when Z is in top position with Elastomer dampers. That’s why we need higher doors and uprights.
C: Distance from bed to bottom of the printer seems to be the same
To sum up, Prusa-box height need to be increase of 40mm, we will offer:
- Upgrade kit: available on the shop
- New version of Prusabox: available on the shop
