Prusa Steel – Y Axis Mods

Decided to make some alterations to Prusa Steel, having had some issues with Igus Bearings (Y Axis Shifting, slightest mis-alignment with Igus on linear drive can cause problems, so wanted to eliminate any variation) gone back to classic bearings. I’ve also had the Y Axis shafts slide out of the frame due to the pick up.

Heat the M3 nuts up using soldering iron and press into locations. Use all original screws, except on the belt clamp, they are M3 x 20mm. The belt clamp does make tensioning the belt a lot easier, has to be done with the heatbed off. Will design an adjustable tensioner next.
