by Bertho, published
Ball bearing & spring loaded pressure plate for uniform feed regardless of filament thickness
Included in the zip file are:
.par =Solid Edge
For detailed instructions see:
The bearing can be found here for $7.41:
It is a Dynaroll SMR128ZZ A5
The spring OD is 7.72mm, has 8 turns of 1.14mm wire, and a free length of 20.9mm. Sorry, I do not have any part number since it came from my big junk box...
Since I needed to measure the spring used for the Ultimaker Upgrade I documented the steps both for a high accuracy measurement procedure and a simplified one.
Note, the spring for the upgrade is not critical. There is a tremendous adjustment range.
I added a section on Extruder Drive Force Measurements:
The long screw is 50mm.
The shaft screw needs to be 20mm since the yoke is 18mm.
