Tronxy X3 Z hight Upgade
Description
Upgrade for Tronxy X3 after a few issues with one of my Z height steppers I decided to beef it up and use only one stepper it requires some extra holes to be drilled in the top frame details in the top frame section PDF I used a stepped taper drill bit for this for ease. I used a double ended stepper like this https://www.ebay.co.uk/itm/HANPOSE-17HS8401-D-Double-Shaft-48mm-Nema-17-Stepper-Motor-42-Motor-42BYGH-1-8A/362781911415?hash=item54777ca977:g:A2IAAOSwCB1dpcRs And 2 of these gearboxes. https://www.ebay.co.uk/itm/Ratio-1-1-8mm-shaft-90-Degree-Right-Angle-Gearbox-Speed-Reducer-Transmission-UK/392644586518?hash=item5b6b70ec16:g:RO4AAOSwj0Nebuzx Also 1 x 5mm to 5mm 20mm D 25MM L Coupler 3 x 8mm to 8mm 20mm D 25MM L Couplers 1 x 5mm and 1 x 8mm coupler can be slit and made into 2 x 5mm to 8mm couplers to join the gearboxes to the stepper https://www.ebay.co.uk/itm/Shaft-Coupler-Flexible-Plum-Coupling-CNC-Stepper-Motor-Jaw-Spider-For-3D-Printer/143208089394?ssPageName=STRK%3AMEBIDX%3AIT&var=442138282337&_trksid=p2057872.m2749.l2648 and 2 x 8mm flanged bearings https://www.ebay.co.uk/itm/KFL08-Pillow-Block-Bearing-Bore-Diameter-Flange-Miniature-Rhombic-Bearing-8MM/323062501818?hash=item4b380691ba:g:BI0AAOSwBRVaczNj details for fitting and cutting parts is in the frame assembly PDF.
