Sorry, this is a double post - it originally came back as spam so I wrote another.
Right, in experimenting with this I've come across a few problems - one of which is that Cura withdraws a large amount of filament before printing when a model is sliced there, but I can't identify the line of code doing it. But one problem at a time. I have tested each of the following lines one by one and discovered that you need a new line after the last line of code for it to be performed. But I still can't get a one off extrusion to test a pre-print filament advance. [G28 M109 S200 G1 F3600 X100 Y100 Z15 E10.0 ] Any ideas on what on earth I've missed? All I want to see the code do at the moment is extrude some filament to make up for the loss after expansion at the end of a print.
Thumbs up for this. I designed and printed off quite a complicated, 'organic' suspension linkage. It can be a challenge to set up something with very specific dimensions and I can't remember if the construction of your part uses associativity, but for 2-3 day courses it will be great. Window's 3D builder has some useful functionality too.
