Electric Spinning Wheel

Electric Spinning Wheel

This is a spinning wheel with a big orifice of 25mm useful for making art yarns.

I have printed everything with a e3d v6 volcano 0.8mm nozzle in PETG, layer heights from 0.2mm to 0.4mm without any support.

Bobbin:
1x Bobbin_A
1x Bobbin_B
2x Bobbin_Shim
2x 6903 Bearing

• Print 1x Bobbin_A, 1x Bobbin_B and 2x Bobbin_Shim.
• Drill open the hole on the bottom of Bobbin_B (the closed hole makes it print without support). - Press both together.
• Put in one bearing at the top and one at the bottom.
• Insert a shim into each bearing.
  Everything should be press fit, but depending on the printer a bit of sanding or gluing might be required.

Flyer:
1x Flyer_Body
2x Flyer_Clip
2x Flyer_Ring
1x 6007 Bearing
2x Aluminium Rod 8mmx250mm
1x Steel Rod 10mmx280mm (Alu should work too)

• Print 1x Flyer_Body, 2x Flyer_Clip and 2x Flyer_Ring
• Sand the surfaces where the wool will pass (maybe even laquer)
• Sand, file or grind the end of the steel rod so it fits in Drive_Coupler
• Put the 3 rods into the Flyer_Body and add Flyer_Clips and Flyer_Rings

Tensioner:
1x Tensioner_Block
1x Tensioner_Wheel
1x Synthetic Cord
3x Ring Screw Hook
1x Dual Hook Spring
4x M3x30 (up to M3x40) Screw
4x M3 Square Nut
4x M3 Washer

• Print 1x Tensioner_Block and 1x Tensioner_Wheel
• The spring should be soft, you can combine multiple springs in series to make it softer.
• Mount to the Base_Plate according to the picture, the two hooks at the Bobbin should be placed aligning with the bobbin because the Cord will hold it in this position.
• From there the cord can be routed anywhere, the Tensioner_Block can also be anywhere.

Front:
1x Front_Top
1x Front_Bottom
1x Front_Hook
4x Front_Joint
1x Front_Cleat
1x Front_Knob
2x 2mm Nail or thick wire
1x KY-040 Rotary Encoder
3x M5x35 Screws
3x M5 Locknuts (other nuts will work too)
6x M5 Washers (bottom washers can be bigger if possible)

• Print 1x Front_Top, 1x Front_Bottom, 1x Front_Hook, 4x Front_Joint, 1x Front_Cleat and 1x Front_Knob
• Put the Front_Bottom at the front center of the Base_Plate and drill 5mm holes for the screws, 8mm-12mm for the cable of the KY-040
• Shorten the axis of the KY-040 to about 5mm
• Put 5 wires on the KY-040 put them through the hole and glue the KY-040 to the Front_Bottom, you can use color coded dupont wires, I put a SM2.54-5P connector at the end to later connect to the Arduino
• Put the Front_Knob on the KY-040
• Screw the Front_Bottom to the Base_Plate
• Glue 2 Front_Joint into Front_Top and the other 2 into Front_Bottom
• Connect Front_Bottom and Front_Top by interleaving the Front_Joints and fix with a nail
• Fix the Front_Hook to the Front_Top with a nail too
• Put Front_Cleat into Front_Bottom, this is for parking the wool while pausing spinning

Footswitch:
1x Footswitch_Pin
1x Footswitch_Top
1x Footswitch_Bottom
1x Guitar Effect Button
4x M4x20 or M4x25 Screws
4x M4 Square Nut
1x ~2m Cable with at least 2 wires
1x Male and Female connector with at least 2 connections. Headphone or Guitar plugs will work best

• Print 1x Footswitch_Pin, 1x Footswitch_Top and 1x Footswitch_Bottom
• The Footswitch_Pin might need to be sanded a bit to slide smoothly into the Footswitch_Top
• Pressfit the Footswitch_Pin onto the Guitar Effect Button
• Solder the cable and screw everything together
• Alternatively any generic binary foot switch will work too but not continous ones from sewing machines

Base:
1x wooden Base_Plate 250mm x 440mm
Some wood pieces as border or rubber feet

Drive:
1x Drive_Back
1x Drive_BackCap
1x Drive_Coupler
1x Drive_Front
2x 6000 Bearings
1x 6903 Bearing
1x Steel Rod 10mmx60mm (Alu should work too)
1x GT2 Pulley, 60 Teeth, 10mm ID
1x GT2 Pulley, 40 Teeth, 8mm ID
1x GT2 Belt, 280mm x 6mm closed
1x 57BLF01 BLDC Motor
1x JYQD BLDC Driver (the version without hall sensing should work too)
4x M5x45 Screws
3x M5x35 Screws
7x M5 Locknuts (other nuts will work too)
10x M5 Washers (bottom washers can be bigger if possible)

• Print 1x Drive_Back, 1x Drive_BackCap, 1x Drive_Coupler and 1x Drive_Front
• Shorten the motor cables and solder to the driver board
• Mount the motor to Drive_Back the driver fits in the cavity below
• Put in 4x M5x45 through the motor and Drive_Back but don't use the nuts yet
• Put 2x 6000 Bearings in the top of Drive_Back
• Put the 40 Teeth Pulley on the motor shaft, screw side facing to the front
• Put the Belt on the 60 Teeth Pulley and put it in trough the top, this pulley needs to face the other way around
• Push the Steel Rod through the 2 Bearings and Pulley
• Align the pulleys so they move tight but without grinding and tighten the grub screws, if you use steel rod the top grub screw might not bite into it but you can file down a flat portion on the rod about 1mm deep at the area where the screw will be
• Pressfit the coupler on the Steel Rod add the 6903 Bearing
• Mount Drive_Front to Drive_Back, fasten with 4 Washers and 4 Locknuts
• Finally the Drive can be mounted to the Base_Plate, this is not done by measurement but by fit, since some of the manual steps will have accumulated inaccuracy.
• Insert the Flyer into the Front and put the Drive onto its end. Align everything so it fits without slack, then mark the holes to mount the Drive, also shorten the Base_Plate to be flush with the Drive
• Fasten it with the remaining nuts and washers.

In the end all the wires need to be connected to an Arduino compatible microcontroller. I used SM2.54 Connectors to make it easier replacable and flashable. You can use any power supply from 12V 3A up to 48V but at 48V the wheel will run much faster. Controlling the spinning wheel is done with the rotary encoder, clicking the encoder or the foot switch will pause it, clicking it again will resume at the same speed and direction.
This is rather long, there might be mistakes in here. Feel free to ask questions.
