My core one and core one L extruder tests are failing miserably
When I run an extruder test to see when I tell it to extrude 100mm if it extrudes 100mm, it only extrudes 90-91mm. I just received a new C1L today, and it is experiencing identical results.
I follow the guide here to mark 120mm and then extrude 100mm, and subtract the remainder to see how much was actually extruded. https://ellis3dp.com/Print-Tuning-Guide/articles/extruder_calibration.html
I have been extruding with an extrusion multiplier of 1.1 when calculating flow rates earlier. It was only until I read that guide that I discovered my extrusion was so far off from what it should be. It's consistent across both printers, and I'm now curious about your results. I reached out to support and was just told to adjust extrusion multiplier. But e-steps should be set from the factory and I find it strange that it is this far off on two printers.
