Printer finishes but sometimes doesn't think it's done
-
This is a real weird issue .... most of the time the print finishes, DWC reports 100% complete and the printer reports the status as 'idle'. Well, every once in a while now, the print finishes to 100%, the tool unloads (Jubilee), the carriage goes to the parking position and stops but the printer still reports the status as 'printing' even though all heaters have been turned off.
In a possibly related issue and again only intermittently, as the carriage goes to the parking position it sometimes makes an odd noise as if the motor was skipping. The travel at that point is only along the Y axis and I have already turned down the maximum speed quite drastically. I have also tested for mechanical hangups and have not found any issues but the printer has definitely lost position.
There is a possibility that the noise and the not finishing issue happen together. It's hard to say because I am generally not present when the print finishes.
There are hiccups and there is a significant difference in the 'messages cued' vs 'messages received' section even though both 'lost' and 'bad' shows as zero. Here is the M122 output:

@jens55 it's fixed in RC2
-
@jay_s_uk Thanks! Cool!
Which one of the issues is fixed or are they both fixed ?
-
@jens55 prints not fully finishing. Not sure about the moves thing
