Printing problems with UM3 firmware to 4.3.2

Posted (edited) · Printing problems with UM3 firmware to 4.3.2

I just updated to 4.3.2 yesterday on my UM3 Extended and now I'm having multiple issues.

 

1) Printer is under-extruding badly

2) Build plate now takes forever to heat up

3) Firmware heats automatically to 60c before the gcode tells it to only be at the temp I assigned

4) After a print is aborted it wants to clear both cores, but I'm only using one. So, I have to wait for it to heat up core 2 and retract nothing before it will continue. I skip through this, but shouldn't have to. I don't know what it would do after completing a print as I haven't gotten that far yet.

5) After aborting print core 1 doesn't retract at all

 

Anyone else having issues or have an idea as to what is going on? Are any of these changes planned for some reason?

I didn't pay attention to what version I had before so don't know what to roll back to. I do see lots of people rolling back to 3.7.7 when they have firmware issues so I'm about to try that myself......

    Well, running 3.7.7 didn't change anything. 

    The only other thing I know I did before was directly after upgrading to 4.3.2 I tried to run a print using CURA to see if I'd like it any more than before. I've been using S3D with great success but thought I'd give it a try. Is there something that could have changed by trying to use CURA after that firmware upgrade?

    I really need some help here as this is currently a giant paperweight.......
