Fixed issues with high speed spindle warm up introduced in v5.2.0.


August 31, 2022

Fixed issues with tool setter introduced in previous release.


August 30, 2022

V2-50 will now pause rather than E-Stop when temperature or pressure limits are outside their valid range, allowing the user to recover by cooling the machine down (or heating it up), or hooking air back up. The spindle is stopped when this happens, and is allowed time to spin back up when resumed via the Cycle/Start button, so the machine must be resumed within 12 hours of being paused to avoid needing a warm up cycle.

Logs can now be downloaded from the History tab, which users can send to customer service to help diagnose issues in the field.

The total spindle runtime on a machine is now displayed in the History tab (keep in mind that machines that shipped out prior to April 2021 may not have been tracking the spindle usage, so that number will be smaller than the actual run time on the spindle).

Fixed pin mapping of physical start button on V1 machines, so the button should now work properly.


March 18, 2022

Fixed bug which prevented Kinetic Control from starting up after updating from the legacy software on a select number of machines in the field.


March 11, 2022

Fixed bug where executing MDI commands through legacy software would corrupt Kinetic Control UI state and crash on the Manual tab.


March 11, 2022

Fixed bug with G54 offsets not being correctly displayed at startup.

Fixed bug where certain rapid movements on rotary axes would cause a following error and trigger an E-Stop.


February 4, 2022

Add .txt, .nc, and .cnc to allowed file types for programs. Previously only .ngc extension was allowed.

Bug fixes


January 13, 2022

Active codes now show smoothing options P and Q next to G64.


January 12, 2022

Added M700 T# code for displaying a load tool message in Kinetic Control to the user. Post processors can use this code prior to the program stop (M0) when performing a manual tool change.

Defaults for the G64 P and Q parameters are now 0.001 inches.

March 31, 2021

Added rotated work offsets (RWO).

RWO allows work offsets to be used in your 3+2 machining operations so that you can avoid programming about the center of rotation of the machine. Instructions on how to use RWO can be found here.

March 10, 2021

The USB download file will now contain any external (i.e. not created or maintained by Pocket NC) software files which need to be downloaded during the normal update process. If no internet connection is available during the update, these files will be used for installation.

Bugfix, removes a configuration value that was undesirably forcing the default network gateway to a route which didn’t allow internet connection. This restores normal behavior, where the machine attempts to automatically set the proper gateway.

January 21, 2021

Bugfix for changes made in v4.7.6, prevents MAC address from changing on reboot.

This update may take longer than usual. Either allow at least 10 minutes before resuming use, or else verify when the machine has rebooted by watching for the front panel LEDs to toggle off.

The changes in this update will not take effect unless the Pocket NC has internet access while the update is applied.
Applying the update while offline will not cause any changes to the machine’s behavior.

November 19, 2020

Updates the ethernet-over-USB protocol used to connect with macOS computers via USB cable. Version 11 of macOS (Big Sur) has removed support for the protocol used previously.

Changes made in this update are only needed for Mac users wishing to connect via USB.

The changes in this update will not take effect unless the Pocket NC has internet access while the update is applied.
Applying the update while offline will not cause any changes to the machine’s behavior.

If your Pocket NC was produced before August 2019
Machines produced prior to August 2019 have an older operating system version that is not compatible with the new protocol. If you are a Mac user with such a machine, please contact our service department.

November 9, 2020

Bug fix for V2-50s. Prevents situations where the warmup routine could be prematurely terminated without giving an alert, while leaving the spindle turning.

This version was originally released as v4.7.5, but it needed a patch so this was revised to v4.7.5b.

August 17, 2020

Fixes bug where the HAL component that reads the V2-50 sensors sometimes failed to stop when services restarted, which would result in multiple instances and cause the pressure sensor to become unresponsive.

August 6, 2020

  • Multiple Rockhopper changes. Small performance gains. Improved logging. Implements async command response and async status items.

  • Can now upload new programs while a program is running.

  • Bugfix, correct jogging increments while in metric units and using UI buttons.

July 17, 2020

  • Improved Rockhopper performance by changing most INI reads to use a cached version of the file instead of reading from disk.

  • Hide tooling options widget on V1 machines (as they don’t have a tool probe button, so the options don’t apply).

Feb 19, 2020

  •  USB drive feature enables use of external storage device for G-Code programs.

  • Performance improvements.


Aug 29 2019

  • Safety switch functionality added.

  • Runtime clock that tracks cumulative time interpreter active when starting a new program or MDI command.

  • Improved display of max-velocity, feed, and spindle values in Run. Override conditions,  pure rotational motion, inverse time mode, and units per rev mode accounted for.

  • Graphs that display previous hour of V2-50 pressure/temperature readings added.

  • Ability to create and enable a swap file through the UI. A swap file allows disk space to be used as additional memory if primary memory is filled. Enabling this will help prevent system slow-downs or crashes when memory usage is high.


May 10, 2019

More V2-50 fixes. Raised temperature limit and stopped tool probe routine from looping


Apr 12, 2019

Bug fix. G54 offset properly account for when tool probing.


Apr 5, 2019

 Fixed several bugs related to V2-50 pressure and temperature sensors. Fixed bug that prevented newly uploaded G-Code program from automatically opening in some situations.


Mar 29, 2019

Integrated V2-50 pressure and temperature sensors. This stops the high-precision spindle from operating without an air supply or outside its designed temperature range. Also added a shorter 10 minute warmup cycle for the V2-50 that is required after 12 hours idle, and raised the idle time before the full warm up is required to 7 days.


Mar 5, 2019

Fixed mouse wheel jogging bug where metric increments were being interpreted as imperial.


Feb 19, 2019

Improved G code program upload/download Prior versions of the UI could only handle files about 2.5MB in size. With this update the UI can handle files over 100MB in size with upload and download indicators to show progress. This allows the Pocket NC to handle programs with millions of lines of G code.


Spindle clocking For machines with the necessary hardware (machines released around June 2018), the measured spindle speed will be shown in the DRO panel. If the machine doesn't have the necessary hardware (the V1 and V2's released prior to June 2018), the DRO will show the commanded speed with any spindle speed overrides applied.


Improved metric jogging increments The Jog widget now has sensical fixed step sizes when in metric mode (1mm, .1mm, .01mm and .001mm).


Improved MDI interface An indicator was added to the MDI input to show when an MDI command was actually sent to the Pocket NC (a green check indicates the command was successfully sent to the Pocket NC). Better error notifications are shown when MDI commands are not successful or are not able to be sent.


Improved Work Offsets panel Fixed bugs with the Work Offsets panel that would trigger a refresh of the UI and/or to improperly set work offsets.


Improved workflow for connecting over ethernet The Pocket NC can be connected to a network using its ethernet port, which is required to receive updates. You can also connect to the Pocket NC UI over the network, but it required changing settings in the Conf tab for it to work. Now you can connect to the Pocket NC UI without needing that extra step.


Sept 13, 2018

Added a status button to the configuration tab to remove programs and big log files from the Beaglebone Board


July 15, 2018

Removed unnecessary Power and Stop buttons, renamed Shutdown to E-Stop and added a power button for properly shutting down the beaglebone
