Dear Patrons,

A week or so ago I posted a request for questions for an upcoming 1 year of Teaching Tech Q&A video.

If anyone here has any questions they would like me to cover, I will try to prioritise them.

Cr-10S Pro, on paper is it worth $600 do you think? Better than Prusa for the money?

Hi Michael, thanks for reaching out to patrons. While following your calibration videos, and looking online, I'm still not clear as to how to calibrate the line width and testing to set extrusion rate or "Flow" in Cura. For example with an Ender 3, I've seen you pass over the 0.48mm value when measuring the sidewalls of the test cube. Digging, I disovered their is some magical percentage range that a line width should be based on your nozzle. So that 0.48 you mentioned is 0.4mm * 1.2 ratio.. (fluid dynamics no doubt) But in Cura the only place seems to be "Line Width" which by default is 0.4mm. So I changed the "calculated" value in Cura to 0.48mm there, and calibrated to a 96% flow rate to get 0.46-0.49mm wall thickness as I went around the cube. Is it typical to have to manually do it? I'm not finding line width settings in printer preferences. Did you do anything to improve the consistency of the wall thickness on each side? With mine, two sides are bang on and the other two are thinner. Is there a way to tweak that? Is it related to X/Y travel? So this is a lot I realize, feel free to say thanks but no, or exctracting ones you want. Cheers!!

Hello Michael, well I believe the only silly question is the one you don't ask, so for myself and other noobies, I see in your videos you say change this and that in the firmware,(I did follow your video to update the firmware and flashed a bootloader)but I have no idea how to communicate with the printer to change this and that.

I'm a bit computer savvy, but when it comes to changing settings in Marlyn and boot loading I get totally lost. Flashing firmware etc.

What's the recommended way to unclog a clogged Ender 3 extruder?

Extruder or hot end? Sometimes the terms are used interchangeably.

Thanks m1kta. I'm so new to 3d printing I never even heard of cleaning filament. I'm going to give the Rigid Ink Floss a try. Reviews seem outstanding on that stuff!
