Adaptation of Yuriy Krushelnytskiy’s TouchDRO project to Sherline lathe and milling machines.
- uses CUI's AMT102 rotary encoder
- requires only adaptation of existing parts, easily modifiable by purchasing a new set of bushings and handwheels
- inexpensive electronic components, including a tachometer
- custom designed printed circuit board eliminates the need for lots of wiring
- based on the teensyduino but compatible with any arduino-based microcontroller
- the TouchDRO project's app is compatible with any Android device with bluetooth
And includes all of TouchDRO's features:
- Bluetooth connectivity support
- Display for up to four axes
- Support for metric an imperial units (mm and inch)
- Support for standard DRO functions:
- Tool Offset
- Preset Dimension
- “1/2” Function
- Hole Circle (Arch)
- Hole Grid
- Point memory only limited by internal storage capacity of device
- Multiple workspaces
- Worskpace preview
Implementation details can be found here:
- mechanical adaptation of lathe and/or mill for rotary encoders
- electronic components and firmware for encoder interface
There is now a second version of the interface (rev 2) with several enhancements. More information can be found here TouchDRO rev 2.
