3D printing guides - Calibrating your extruder
Why 3D Printing Stack Exchange recommends it
3D Printing Stack Exchange answerers point people to it when over- or under-extrusion, clicking extruders or odd surface artifacts may come from a miscalibrated extruder.

What it is
A short 2014 tutorial by Thomas Sanladerer (Made with Layers, then Tom's 3D) on calibrating a 3D printer's extruder steps per mm. It walks through measuring how much filament is actually fed versus commanded, then adjusting the firmware value, using tools like the Prusa calculator, Octoprint and Slic3r.

Following on from Toon's answer, here is a run down of Thomas Sanladerer [LINK] 's excellent video: 3D printing guides: Calibration and why you might be doing it wrong [LINK] . However, this may not be a definitive answer to the actual question about warts and bumps... 0:08 - A step back [LINK] Back in time - when the RepRap project (and the hobby grade 3D printing market) was new territory - it was seen to be a doable technology, with no restrictions imposed by patents. The new printers created and developed included Darwin, Sells Mendel and Prusa Mendel. These often produced unusable parts. However, impromptu solutions, or kludges led to poor quality fixes giving poor quality prints, by to

(answering my own question) The problem was the extrusion distance settings in Cura's advanced tab, reducing the value to 1.5mm solved the problem. Other problems with the same symptoms: Partially blocked hotend nozzle. Incorrectly configured steps per mm for the extruder motor - this youtube video [this video] shows how to test and configure this.

Does anybody have an overview of what things should be calibrated (and in what order) for a certain 3d printer or after changing the printing material? I only know about: calibrating the extruder steps per mm, e.g. Tom's youtube tutorial [this video] determining the print temperature, e.g. RepRap Neo's youtube tutorial [LINK] calibrating the extrusion multiplier (for each different filament), e.g. RepRap 101's youtube tutorial [LINK] How to calibrate/determine the maximum speeds or accelerations?

I'm not a 3d printing expert by any means, but I had some funky layer stuff going on before "wrinkled" first layer & gross edges w/overlap. For my printer, the problem was I was over-extruding. I followed this video by Tom's 3D: 3D printing guides - Calibrating your extruder [this video] For some reason, I had to do it twice before it actually worked. Once I got that calibrated (and fixed an uneven print bed), I was good to go.

I have the TronXY X1, which uses the same extruder and firmware design as the TronXY X5. The clicking does not come from Voltage, but most likely a wrong set up of steps/mm or a lightly clogged nozzle. Quick and dirty steps/mm Start a print that you know clicks. wait for the clicking starts (it comes from the extruder pushing against resistance and jumping back a step) Go into Configuration > Extruder > Steps/MM alter it down a little, listen if the constant clickig stops, alter again if needed. Now, you need to make sure not to get into underextrusion doing this "on the go" fixing, and you really should calibrate your extruder. Proper calibration To calibrate your extruder, you could follow
