Part three of my ongoing video series is up - this time, i’m showing how to use Marlin’s PID autotune feature.
Let me know what you’d like to see next!

Great guide! Thank you
Excellent quality video, and just what people learning to 3D print need.
I had been considering doing a “Using a new reel of filament for the first time” video. Showing how to measure the diameter then how to do a test extrusion and calculate the extrusion multiplier. In my experience less than a quarter of people with printers know how to do this, it’s such a fundamental thing to not be doing. I even still find people tweaking their E steps per mm in firmware when they use new filament!
I’m with @Bracken_Dawson on the extruder calibration thing. I think a prerequisite would be how to calibrate E-Steps for a hobbed bolt though.
Once you have Steps/mm sorted then you can usefully move onto diameter measurement.
How to on Auto Bed Leveling.
Polulu (and clones) driver tuning. Lots of crank it up to 11 “why an I dropping steps” going on.
@Bracken_Dawson @Sanjay_Mortimer extruder calibration it is for the next one!
@Sanjay_Mortimer want a “assembling the E3D hotend” one ;-)?
@Mohamed_Thalib_H that’s one that i’ll need to dive into myself first - my current printer is all manual still.
@Joe_Spanier planned. There’s a lot of factors going into a “perfectly” tuned driver and i’m still working out how to cover as many of those as possible.
@Thomas_Sanladerer
If you want to do a hotend assembly video I’ll get you something a bit more… special than a v5 to play with in the post. It’s much more “videogenic” and easier to assemble.
@Sanjay_Mortimer NDA required?
You know what, i need to order a pair of regular v5s anyways, feel free to add any special ingredients to the package.
Great vid Thomas. I would love to see something on micro stepping. I keep hearing about it, but have no idea what’s involved.
@David_Gray thanks, one more point on my list! I guess i’ll have to make a sub-series about mechanical and electrical basics, like how a stepper motor and driver work, some electrical basics to help the more mechanically inclined folks understand what those numbers on the power supplies actually mean and an overview of linear drives and so on.
@Thomas_Sanladerer , what would you say if i can add spanish subtittles or maybe double the audio?
@Nicolas_Arias that would be awesome! Youtube doesn’t allow dual audio, but i can replace the automatically translated subtitles with proper ones.
