Wanhao D9 / MP Pro MK1 16 Tooth X Axis Upgrade

thingiverse

These X axis ends use 16T timing pulleys (instead of the 20T) to help with the triangle belt problem common in these printers. You must tap the ends of the 2020 vslot extrusion with a M5x0.80 tap. You will also need a longer belt GT2 timing belt. The Idler end has a tension screw to adjust your belt tension. You can use any M3 thumb screw for the tensioner. I used this one: https://www.thingiverse.com/thing:29782 Don't forget to adjust your steps per/mm in your firmware (M92). Most of the stock hardware can be used in addition to the following: QTY: 2 - M5x0.80 20mm Hex Screws QTY: 1 - M3x0.50 22mm Hex Screw QTY: 1 - M3x0.50 40mm Hex Screw QTY: 1 - M3x0.50 Regular Hex Nut QTY: 1 - M3x0.50 Lock Washer QTY: 2 - M3x0.50 Nylon Locknuts QTY: 1 – 16T GT2 Timing Pulley 5mm bore (for motor) QTY: 1 – 16T Idler Timing Pulley 3mm bore QTY: 1 – GT2 Timing Belt 2mm Pitch 6mm Width at least 110mm long Print with the flat side down and with supports (see pic).
