Regarding PT2000 automatic diagnostic issues

[runTao]

When I enabled automatic, the simulated nozzle malfunctioned and could not continue to work after recovery; Using software interrupt to simulate nozzle failure, the nozzle can continue to work after recovery。

Thank you, this issue has been resolved.

But I have a new question.Why can't my jetting function properly when the D_LS1 and G_LS1 pins in the image below are in a floating state?

Hi,

When using automatic diagnostics, check if the recovery process includes any steps for re-initializing the nozzle or system components after a failure is detected. If the system does not reset or properly transition out of an error state, it could prevent the nozzle from working post-recovery.

If the software interrupt method works, check the difference in configuration between manual interrupt handling and the automatic diagnostic feature. There might be subtle differences, such as error flags or status registers, that need to be cleared in the case of automatic diagnostics.
