FuckIO

An opensource fucking machine, that is far superiour to anything on the market.

Specs

• Easy to built just with a 3D-printer, screwdrivers and easy-to-source parts.
• Completely 3D-printable with easy to print parts and almost no supports. Also avoiding tight tolerances to make this accessable as possible.
• Simple, yet verastile mechanics.
• Based on a linear position drive, not a crank mechanism.
• An 24V PWM output to drive external systems. Could be lube pumps, vibrators, etc.

Mechanics

The mechanics is a direct derivative of an other open source project called OSSM. You can also find some informations about this build on their Discord. https://github.com/KinkyMakers/OSSM-hardware

The motor mount is designed for a NEMA23 servo or stepper motor. Any motor fitting to this standart should work.

BOM

• iHSV57-30-18-36-... integrated servo motor from JMC
• 24V Power Brick Mean Well GST280A24-C6P
• 40cm MGN12H linear rail
• 4x 605-2RS Z2 bearings
• Micro Switch
• GT2 20 Tooth Pulley for 8mm Axis and a 10mm belt
• GT2 belt with 10mm width
• Various M3 and M5 screws and nuts
• OSSM Ref Board from Research and Desire: https://shop.researchanddesire.com/collections/all/products/ossm-reference-board
• M5 Stack Remote Control from Ortlof: https://github.com/ortlof/OSSM-M5-Remote

Control

Firmware

The currently best firmware is the official OSSM firmware, or Ortlof's firmware for the M5 Remote https://github.com/ortlof/OSSM-M5-Remote

The firmware in the repository can only be used in conjunction with node-red.

The firmware uses the following projects:

• IotWebConf for WiFi provisioning: https://github.com/prampec/IotWebConf. Check the end-user manual on how to use it.
• MQTT for communication: https://github.com/256dpi/arduino-mqtt Albeit SSL is not supported.
• My own library for generating the stroking motion: https://github.com/theelims/StrokeEngine/
• Which in turn uses https://github.com/gin66/FastAccelStepper for step generation and interfacing the servo motor.

node-red

I've setup a node-red instance on my NAS to control FuckIO through MQTT messages. Have a look at the provided flows.json to draw some inspiration from.
