Pasta Machine drive motor

thingiverse

This project started because I had a dead printer scanner going to the tip I disassembled it and recovered several useful parts. Since it contained a decent dc motor and power supply I decided to make myself a drive motor for my pasta machine. The motor is factory fitted with a metal toothed belt pinion. I filed off the flange and filed a flat onto the pinion in order to accept the printed pinion. something similar found here. https://www.ebay.co.uk/itm/OEM-Canon-Pixma-iP4300-Printer-Belt-Drive-Motor-QK1-3042/192893271834?hash=item2ce955bf1a:g:btwAAOSwU~VcuQ5q The printer contained a dia6.9mm steel shaft which I used for the axles of the 2nd and third gear. axles 28.6mm long. I filed 2 flats on the remainder of the steel shaft and used it to ream the centre holes of the printed gears. I used the dia 9.5mm steel paper feed roller to make a square drive shaft to match pasta machine drive. 50mm long. I drilled and pinned the square drive to the final gear. 2 m3x14mm pan head screws make the pegs for the drive. 10 m3 self tapping screws recovered from the printer hold the assembly together. 2 original machine screws from the printer motor fix it in place. Speed control as well as forward and reverse are provided via the dc motor controller which was purchased for the project. https://www.ebay.co.uk/itm/DC-6V-12V-24V-3A-Reversible-Motor-Speed-Controller-Regulator-Driver-Switch-PWM/173517709342?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 The 24v supply line from the printer powers the project but I have yet to design an enclosure for it. The power jack was recovered from an old router which was also going to the tip. Gears were designed in fusion 360 using the spur gear plugin. Each gear progessively steps up the tooth module to make the teeth stronger as the speed is reduced through the gear train and the torque increases. I used a backlash of 0.2mm. Gears printed in PLA with 0.1mm layer height 20% infill. Initially gears were too tight to mesh but printing at 99% scale solved that problem. Other parts printed at 0.2mm layer height 20% infill. Print gears with the chamfer side down to reduce elephant foot. The electrics case could benefit from supports as does the bottom case video https://vimeo.com/user104852921/review/371210122/4805199f0b
