Printing different model sections with different materials

Hi experts, I've done a lot of printing with single extruder machines and do fine. Now trying a dual (nozzles at same fixed height). I've done a few basic things and I thought printing the model below would be easy enough with dual extruders but no success. turbinedisk.jpg The turbine disk has fine ...

Re: Out of ideas - print surface issue

Much, much better 0.5mm nozzle now.
Still a little tweaking to do.
In the end the only real change was the hotend.

Re: Color picker to change color of build plate

Thanks CCarl, I hadn't thought of that.

Re: Out of ideas - print surface issue

Gave up on the JHead (original) replaced with an E3D V6 (original). I don't know why there would be such a difference. Same filament, same .stl, this pic JHead although 0.5mm nozzle. Vase2.jpg E3D print 0.4mm nozzle, first print was a 20mm cube, looked fine, this is second print, still needs some tu...

Re: Out of ideas - print surface issue

Ended up bad looking, got worse as it narrowed. I'll try again when the air isn't so wet.

Re: Out of ideas - print surface issue

An update, haven't been printing with that machine. Just had a look, my PTFE guide into the J-head had a gap. Probably no issue. But I did find a very small sliver of tubing inside the nozzle, like a tiny finger nail clipping. All cleaned and purged, its printing a small vase right now. Using the sa...

Re: Color picker to change color of build plate

Agree, for a different reason, after yet again accidentally stopping a print. I have four printers running off 2 instances of S3D on two laptops.
Something like this would help so I know which window is operating which machine.

Re: Out of ideas - print surface issue

Thanks guys, I do have another new j-head so I'll put that on and try it this weekend. Perhaps it has a machining defect. I can easily push through the filament by hand. I'm sitting next to a large vase printed in that green on another machine. It has that nice pearl luster and the layers are clear ...

Re: Out of ideas - print surface issue

Yep, that exact same green filament prints great on another machine. The multiplier is high because it is far worse (under extruded) at 0.9, which is what the other printers use just fine. Not this one though. Notice the first layer or two of the cube section is clear, that is how the rest should be...
