Iāve updated from 1.5.6 to 1.6.2. When running any code it would āHoldā and canāt be recovered with any buttons. Emergency stop then start at a specific line allowed it to continue. Even occurred with surfacing code generated by Tools. Continued to freeze at the same code line after 3 separate tries.
Reverted back to ver 1.5.6 and code worked fine. Occurred on 3 different code files. I like the new features and would like to upgrade .
Your connection widget shows youāre connected as grblHAL - go into Config and swap the fallback firmware to grbl instead of grblHAL (inside the Basics section, right at the top). That should fix your issue.
