Since my post on extruder calibration, the Prusa firmware 3.0.12 has been released. The problem with this release is that it doesn't allow extruder steps/mm to be saved to the EEPROM anymore, which many of you have noticed and commented about. The reason for this change was that it would supposedly cause issues for users … Continue reading Saving extruder steps with 3.0.12 firmware

Linear Advance
In early April, a member of the Prusa i3 Facebook group posted about a feature of Marlin firmware that they had come across named linear advance. Documentation for the algorithm can be found here. In a nutshell, LIN_ADVANCE enables a pressure control feature which sets the pressure inside the nozzle to the needed one according … Continue reading Linear Advance
PID Tuning
PID tuning is a fairly quick and easy process that can make a big difference to your print quality. If you can see while you're printing that your extruder temperature is fluctuating up and down by a few degrees then a quick PID tuning can help to make it rock solid. Temperature fluctuations can even … Continue reading PID Tuning

Often when you go to calibrate it for the first time, you'll find that your calibration is actually a long way off from what it is supposed to be and you've been printing with it set incorrectly all along. There are two parts … Continue reading Extruder Calibration
