I have been exploring deeper into 3D printing and how I might improve the already excellent SnapMaker. I read about calibration of the extruder. It seems that most printers need to be calibrated so that the GCode which sends an extrusion command matches the amount of filament extruded. Quite simply, when a command is sent to extrude a certain length of filament, we need to be sure that the amount actually extruded matches.
For my Snapmaker I carried out the test here: https://mattshub.com/2017/04/19/extruder-calibration/
I found that my Snapmaker was under extruding by 10% (A command to extrude 100mm of filament actually extruded 90). I ended up changing my E value from 92.6 to 102.9. I did this using the machine control panel in Simplify 3D with the Snapmaker directly connected to my PC (iMac) with the supplied USB cable.
10% seems like a lot, and I was not noticing any significant under extrusion in my prints. Since changing the firmware calibration factor for the extruder I have done a couple of prints and not noticed any significant differences, but I guess it can’t hurt?
I’m just about to print a 25mm cube and see if I need to see my extrusion multiplier (for PETG I currently have it set to 1.00).
Has anyone else done this calibration on their Snapmaker?
