Cancelling Print causes crash #185

Closed mwelby closed 3 months ago

mwelby commented 3 months ago

Hi on the Neptune Pro 4 - the firmware crashes if you try and cancel a print.

I have tried both in the Klipper interface and on the touchscreen and both exhibit the same issue.

If you need logs or further info, please let me know.

If you issue CANCEL_PRINT via fluidd or by pressing Stop on the touchscreen, the print should finish the buffered gcode then issue a print end (early).

The red (emergency) stop button top right of both fluidd and the touchscreen (M112) should cause an immediate print cancel causing klipper firmware to shutdown, requiring a manual firmware restart.

So when you are issuing CANCEL_PRINT is it crashing or stopping firmware? Klipper's firmware? Or the touchscreen display firmware?

Hi,

I am guessing I am probably not waiting for the buffer to clear - how long is the buffer?

The emergency stop works instantly.

The only one that seems ages is in klipper and the touchscreen (Cancel)

I'm not entirely sure what you describing. Using the button to Stop from the display or fluidd is not immediate, that is correct. As @halfmanbear described the buffered gcode is executed first.

Where exactly are you seeing the crash and what is the error message?

mwelby commented 3 months ago

Please ignore this - I think it's just me being impatient while the buffer clears and then stops the print.
