Most likely the "Flow %" in the material settings (on the printer), at least you can check that. Was this the first time that you've installed the tinker firmware? I don't know, how many settings you have customized, but if you switched back and forth between standard and tinker firmware recently, a factory reset would be the best choice (the stored settings in EEPROM are not longer compatible for the "+" models). Thank you, you were right, it was the flow was changed. And I've done a factory reset. Back on the track

Slowly after 20cm, it looks to be a normal print. I made new program with new Cura, where it will also be just 50%. What have I changed and where do I fix it?

And why is the extruder at 50%?

I have a Ultimaker 2 + extended. Mounted "Bond Tech QR" and installed Tinker Gnome 16:08 2+. Changed the location of the cables to the motor for the correct direction. Axel E = 492.45 and motor E = 1000 But it extrudes almost nothing, see attached picture: What's wrong?

Is there support for running the same material in both the nozzles, the printer switches nozzle when the material runs out in the first. It would save a lot of attention and material for me.
