UGS no longer connects to Genmitsu 4040 ProMax #2737

|
I have been using USG (20250108) on a MacBook Pro to connect to a 4040 ProMax CNC successfully for the last few days. This afternoon, after modifying some of the designs, I reconnected the MacBook Pro to the CNC with the USB cable and clicked the connect button in UGS. It changes status to connecting and then immediately disconnects without any error. I have included the console printout for reference. I have tried to delete / reinstall UGS. Powered the CNC off and on. Rebooted the MacBook and so on. No change. Keeps disconnecting immediately after connecting with no error message. |

The controller reports that it is in a DOOR state. This state will prevent the execution of any commands and the initialization can not continue. On older GRBL boards it would automatically reset it upon connection. The newer 32-bit variants does not. I have added a check for it and will automatically reset the board in the UGS initialization sequence which should fix the problem. This is available in the latest nightly build of UGS here: |

Thanks for the quick response. I installed the new build and - so far so good. Connects beautifully. |
