K8200 Dual Z Axis Motor Conversion

thingiverse

Get rid of all Z wobble once and for all by utilizing most of your printers parts. You will need one more stepper motor, two LM10UUL bearings, two 608Z or 608ZZ bearings, two rigid couplers measuring 8 to 5mm, and two lead screws (30cm) along with some assorted screws and cable-ties. I printed my parts in PrimaValue PLA from www.e3printable.no because there is really no load on any part that can be considered heavy. You are free to print in carbon-infused nylon if you prefer; it makes no difference to me. Note: The adjustment for the Z-axis endstop was not included in the picture as it was added later. Print Settings: * Printer: OtterBot (my heavily converted K8200) * Rafts: No * Supports: Yes * Resolution: 0.2-0.3 * Infill: 20% or more Notes: Print the 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 a 0.4mm nozzle wall). To secure the LM10UUL bearings, use Zip-Ties (cable-ties). Create a Z-axis adjustment screw by combining a 3mm nut and a long 3mm screw. For the Z axis to be held in place, you will need two regular 608Z or 608ZZ bearings. The entire top frame must be moved back approximately 27mm, and the extruder must be shifted 14mm to the left after the build to accommodate for the relocated extruder. If you prefer to print individual pieces rather than the whole print in one go, note that I have not optimized their printing orientation. To achieve this: * Duplicate and flip the ZRodBearingHolder and the Motormount in the Y axis. * You will need four X Z_Carriage_Rod_Clamp. Have fun!
