Manual bed levelling on the Startt 3D/TronXY XY-100 printer is awkward with the provided thumbwheels. There are some good solutions on the net but most thumbwheels are too wide for these printers and interfere with the build plate Y-Carriage.
My solution was to design a long and slender thumbwheel that works with the Startt 3D printer as well as other kit printers on the market.
Also included with this design is an alignment washer which is placed at the bottom of each bed plate spring.
Make sure that the 4 machine screws at each corner of the bed plate are tightly secured with M3 nuts and a bit of loctite prior to assembly onto Y-carriage.
There is a bit of built- in clearance in the thumbwheel, so apply a dab of CA to nut prior to inserting into thumbwheel. Allow to dry thoroughly.
