Would love to know how you get your nozzles from not drooling during dual extrusions.
Also, is that delamination on your traffic cones?
As to that, it is a very basic but efficient technique : I use the "change tool scripts" to turn down the unused hot end while powering the new one.
No heat = no oozing.
No heat = smaller hot end (no thermal expansion) => no idle head colliding with the build.
Admittedly it is an efficient way to do things only in when the 2 colors are completely on different planes. It still works otherwise but it increases print time like hell.
So when I transition from white (hot end 0) :
M104 S0 T0
M109 S200 T1
And then the reverse
M104 S0 T1
M109 S200 T0
I usually add a little more text to move the head away from the build first and then bring it back (I think it uses G91/G92 and move commands).
Unfortunately correct, but this is entirely on my design. I wanted to overdo it and added a "radius chamfer" at the bottom that had a horizontal tangent... therefore it didn't work well since the first layer had nothing to support it. Print didn't fail though so I'll keep it once I fill the hole with compound.
I have read about this technique, how much longer are we talking?
I want to do some dual extrusion but I will have two colours on the same layer so I think this would make the print incredibly long. Not to mention the PITA of printing hot ABS into sections of already cooled ABS... warp city...
Oh yeah... do you add all that code manually or does the software do it automatically?
S3D adds the code on its own if you put it in the tool change script.
For my machine it takes about 3 mins to bring the hot end to temp. So if it is only a couple times per print ... No sweat. If you do it at every layer... Better be patient.
Oh and i only do this with pla and pet... Never tried ABS so far.
A couple more things I made recently :
1/ a replacement for our waterski fin.

2/ a repair for a colleague : fits better than original !

Sorry for the newbie question... but waterski fin in PLA? Does that not degrade in saltwater? I thought that ABS was better for parts that would be exposed to the elements.
Got it. Thank you for the clarification.
