Retraction Temp, Length and Speed towers.

thingiverse

I'm having some trouble dialing in the retraction on PETG, so I'm using some towers based on m1ngr's design to test the effects of temperature, retraction length and speed. I simplified the object a bit by removing sharp corners and making it a single solid - I printed with 3 perimeters, 3 bottom layers, no top layer, and no infill. Of course, I made it so there are two of the towers. You need to have firmware retraction enabled for this to work! There are three versions of the python script - one for each setting. I was really lazy here, but I could have added parameters and made it more robust, this was least effort and produced good results.
