TouchDRO Release Notes
TouchDRO gets a handful of substantial updates a year, and the firmware on TouchDRO adapters is updated too. This page lists the application releases newest first, and each one has its own page describing what changed and why it matters, with links to the manual pages that cover the new functionality in full. The adapter firmware releases are listed together on one page.
Getting App Updates
You get app updates through the Google Play Store and the Amazon Appstore. If you want new features as they are finished rather than a few months later, you can join the open beta track on Google Play. The "TouchDRO Releases and the Beta Track" page shows which versions are current and explains how to join.
Adapter firmware updates are installed from the TouchDRO application. When a newer version is available for your adapter, the "DRO Adapter Details" dialog shows "Update available" beside the firmware version. See "Updating the Adapter Firmware".
TouchDRO App
TouchDRO 3.32
October 2026. A large release. DXF drawing import, lathe thread cutting, lathe cutter geometry, live video from a USB camera or microscope, measurement mode with probing functions, the probe library with tip diameter calibration, DXF export, rotary table support, scale error correction maps and the recording wizard that builds them, backlash compensation, angle vectoring for compounds and tilted mill heads, calibration that belongs to the adapter instead of the machine profile, live data streaming over TCP and MQTT, and settings backup. The 3.32.01 update, later the same month, fixes readouts that could stop after a machine profile switch and combines the mill's two tool compensation functions into one. The 3.32.03 update adds "Outline from Points" for digitizing a part, "Distance Between Lines", a best-fit "Circle from Points", Z capture from the "Indicate Workpiece" wand, in-place editing of drawing geometry, and adapter renaming and probe contact types in the adapter details. It also adds adapter firmware updates from the application.
TouchDRO 3.25
March 2025. Holes between two points, the radius and arc cutting function, a caliper readout on the lathe, sub-datum filtering, and a cutting speed display next to the tachometer.
TouchDRO 3.24
April and June 2024. TouchDRO Plus becomes available with TDA adapters. Plus adds automatic edge detection, the reference image overlay, automatic guide lines, sub-datum and tool library import and export, and automatic zero. Also a new adapter protocol with lower readout latency, the Adapter Details dialog, and automatic touch-off in Set Z Reference.
TouchDRO 3.23
April 2023, the release known as TouchDRO V3. A new user interface, configurations, flexible input mapping, touch probe support, the calibration wizard, the rebuilt graphical view with guide lines, and separate cutter radius and tool height compensation.
The last TouchDRO 2 release was 2.5, in August 2016. Its release notes are on the original TouchDRO blog.
Adapter Firmware
Adapter Firmware 3.6
A reliability release. The touch probe ignores electrical noise and reports more consistent positions, the Bluetooth connection recovers on its own when the tablet stops responding, firmware updates are safer, positions are kept through restarts and updates, every TDK-40 and TDK-40T kit becomes a TDK-40 Plus, and every TDA-400 becomes a TDA-410. The "Adapter Firmware Release Notes" page covers every release back to 3.0, along with the firmware edition for each adapter model.
