Trouble changing filaments mid-print

[sloverlibrary 0]

Hello,

I am having a problem with my UM 2+ with changing out and adding in another filament color mid print. it does spit out the filament, but when I try to add in a new color, it spazzes between heating and cooling after the material section menu. I thought it may be the fan causing this, but it still has the same issue when I try it again.

Anyone else had this issue before? Is there a way to resolved it?

Short answer: downgrade to an older version of the firmware, if you need this function.

So I guess I'm not the only one running off the original UM2 firmware. I did update once everything went sideways. :angry:

Hi DeathMachine,

No, you are not alone for sure! I'm using the old firmware from 15.04.6 and this is the best match for an UM2 IMHO.. If I want a predictable print, I'm using Cura 15.04.6 period. I'm also using S3D, but mostly for monitoring the "gcode files" (the model) as this really give you a true picture of what to expect.

Sorry, but the new versions have to many issues, so I'll wait until all this is some stabilized.

Thanks.

Torgeir.
