Instructions

Print out all objects in file : ( Including the Spacers )

Locate spacers to rear, to clear belt / pulley correctly ...
Use M4x40mm bolt plus spring adjuster ... ( should move freely with slight resistance from spring once installed )
Adjust till the printer head is just touching the bed, then back of 1/2 a turn ... ( use the paper trick to get the setting correct )

Note : The slots in this design allow for some minor adjustment to get the end stop precisely lined up ... ;)

Tip : The larger spacer is for M4 bolt, placed in between gap ... ( not needed )

Cheers, Bantum ...
