BondTech Mini Wanhao i3 Upgrade Kit

BondTech Mini Wanhao i3 Upgrade Kit

Regular price $0.00 $123.31 Sale

Bondtech Mini with Dual-Drive gears that grips the filament from both sides without any slippage or grinding as an upgrade kit for the Wanhao I3 printer.

The smaller effective diameter of the drivegear will increase the torque by about 50% and also the resolution will increase with 50% since the E-step value is 140 compared with the 96 as the standard extruder.

The filament path is fully guided and this makes the extruder work perfect with both hard and soft filaments, the drive gear is also in hardened steel to withstand wear from especially filaments with abrasive additives like carbonfiber and glassfiber.

The quick-release lever lets you load and unload filament with ease for quick filament changes.

Spring loaded pre-tension on the filament.

This kit uses the original steppermotor that came with the printer and is installed in 1h. Step-by-step guide is supplied.

The kit consists of the following:

  • Extruder parts in nylon with thread inserts.
  • Hardened drivegears in steel.
  • Needlebearings.
  • Harded ground shaft.
  • Bolts M3x45 mm
  • Shim in alu.

For simple installation we have now produced a custom mounting bracket as you can find below in recommended parts.

The original metal plate that holds the extruder needs to be modified in order to give room for the extruder, this is easily done with a hacksaw and a file.

Maximum X-movement is restricted about 15 mm on the right side.

E-step needs to be adjusted to 140 step/mm (with the LCD panel)

Weight: 62g

Note! The version 2.1 of the WanhaoI3 have a different part cooling fan housing that will make the housing to be lower than the nozzle, a custom printed part cooling fan housing could be used instead.
