CncControl plugin to Repetier-host


A Repetier Host plugin focused on CNC machine operationss. Working with CNC machines require slightly different user interface for frequent tasks such as jogging and height probing as the machined objects can be clamped at different positions on the bed. This plugin combines thoose into one panel in an intuitive way.

  • Jog with keyboard (instead of mouse + click) - enabled only when the plugin panel is focused.
  • Easy access to Z-Probe (G30, G31) and one-click-action to set height (G92 Zn.nn) based on the probing.
  • Spindle on/off and PWM
  • G1 assist mode (just three textboxes for coordinates to move to, leave empty to not move one or several axis)
  • G92 assist mode (just three textboxes for redefining coordinates, leave empty to not redefine one or several axis)

Keyboard short cuts


  • Error "Could not load file or assembly 'CncPlugin, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". Windows by default prevents downloaded dll's to be used. See the install instructions above how to unblock the dll.
