@uncle_bob: If you mount the steppers to the midplate where do the bearings go.
On that note. I am moving my design to 4 plates. 5 if you count under the basalt.
I will have the bottom plate which will have nothing mounted on it. Just 3 holes for tensioning the pressure column.
I will have a downward facing electronics plate. The power supply and the controller is on the bottom of it. The face of the steppers are on the bottom of this plate.
I will have an elevated bearing plate that has a big hole in the middle so the extruder can extend past this plate to the build platform.
The top plate will have another 3 bearings.
Mounted above the electronics plate on stiff springs tensioned with M8's with big printed thumb screw attachments will be the build platform. It will actually be a wooden seat for the hot bed with the basalt on top.
This whole new design will have the columns pulled in like you are doing yours.
What do you think? This will add about 75mm to the build height. So I will be pushing a 200mm diameter by 300mm tall build volume.
This will also bring the bearings closer together making the machine more rigid.
