Linear Advance Bridging Test

thingiverse

Hello Makers, this test is for printers with linear advance capability in their firmware or those who simply want to explore bridging functionality. If unfamiliar with linear advance, visit Matt's Hub for an excellent explanation. https://mattshub.com/2017/10/02/linear-advance/ I created this test because I believed that the new linear advance function on Prusa i3 MK2S printers would enable them to handle double the print speeds for PLA. This means 120 mm/s for the print head with standard PLA, and the material should remain stable when traversing gaps. But what bridging distances are possible? That's exactly what this test aims to determine. It begins with a 10mm long bridge (dimensions indicated by green lines) and ends with 35mm on the small part and 60mm on the large one. The bridges incrementally increase in length by 5mm per bridge. This test will also reveal how sluggish your material behaves under different conditions. Enjoy testing your printer's linear advance capabilities – I love this function myself.
