Get rid of all Z wobble once and for all using most of your printers parts.
You need one more stepper motor, two LM10UUL bearings, two 608Z or 608ZZ bearings, two rigid couplers 8 to 5mm and two lead screws(30cm) and some assorted screws and some cable-ties.
I printed my parts in PrimaValue PLA from www.e3printable.no as there is really no load on any parts to be considered heavy. But feel free to print in carbon infused nylon for all I care ;)
PS: The adjustment for the Z axis endstop is not in the picture, as it was added later.
OtterBot(my heavily converted K8200)
Print whole plate COMPLETEKIT.STL in one print at 0,2mm or 0,3mm layer height with more than 20% infill. I used 2 layers sides and 5 top and bottom(2 shells with 0,4mm nozzle walls)
- Use Zip-Ties(cable-ties) to clamp the LM10UUL bearings in place
- A 3mm nut and a long 3mm screw to create the Z axis adjustment screw
- Two regular 608Z or 608ZZ bearings to hold the Z axis in the bottom.
- You will have to move the whole top frame back, and the extruder to the left after the build to accommodate for the moved extruder. The frame must be moved 27mm back, and the extruder 14mm to the right. These are approximate measurements
If you desire to print single pieces, and not the whole print in one print, then note:
- I have not oriented them to the optimal printing orientation.
- The ZRodBearingHolder and the Motormount needs to be duplicated and flipped in Y axis
- You need 4 X Z_Carriage_Rod_Clamp
