Connecting rod joints

You will need the following parts:

# Component Qty Type 1240 Carriage 1 Printed 242 M3x16mm cap head screw 2 Fastener 204 M3 Nyloc nut 2 Fastener 1191 6mm threaded ball 2 Hardware

Lock each M3 cap head screw in place with a Nyloc nut, then fit the threaded balls.Before continued use, the balls should be locked onto the threads with an effective thread locking compound (such as Loctite, or we find superglue works very well although one has to be screwing the ball on). If you prefer to leave this until the machine is built, (in case you need to go back and fix build errors), then leave until after the commissioning stage (which includes a reminder).

Linear bearings

You will need the following parts:

# Component Qty Type Carriage 1 Assembled 241 M3x20mm cap head screw 1 Fastener 258 M3 nut 1 Fastener 1182 Long series 8mm diameter linear bearing 1 Hardware 287 8mm diameter linear bearing 1 Hardware

Push the nut into the centre recess, then fit the cap head screw, leaving it loose.
Slide each linear bearing into the printed carriage. The Long series bearing must be fitted on the same side as the narrow slot (near the centre of the printed carriage).
Lock the linear bearings in place by tightening the cap head screw. The bearings should protrude above the carriage such that the slot is just showing.

Repeat

Repeat the above steps until you have three assemblies.
