Random pauses and will not complete fixed tool change

gSender 1.2.2

Windows 10

  1. Exoeriencing random gSender pauses. Spindle stays on, machine not moving, “resume” button active. Click “resume” and cutting continues.

  2. Experiencing random failure to complete Fixed Tool tool tool change. Prompts for tool change, probes tool (Bitsetter, pushes button down, reprobes to touch), freezes at probe touch. Continue button no active, says running.
