First Layer Problems: A Diagnostic Order That Narrows It Down
First layer problems all look the same and have different causes. A diagnostic order that separates height, adhesion, flow and levelling in about ten minutes.
Category: Calibration
The procedures that stop problems coming back: Z offset, flow rate, pressure advance, input shaper and bed levelling. Run in the right order, each one takes minutes.
Over Extrusion: Blobby Walls, Parts That Do Not Fit, and the Flow Fix
Over extrusion shows up as blobby walls, parts too big to fit, and a rough top surface. How to tell it from other faults, and the two numbers that fix it.
Ender 3 Bed Leveling: The Paper Method, and When to Add a Probe
Ender 3 bed leveling, done properly: the paper method, the knob order that works, when a CR Touch earns its money, and the z-offset step most guides skip.
Temperature Tower: How to Run One and What to Read From It
Short answer Slice a tower so each band drops 5 degC, print it, then judge on bridging and stringing rather than on…
3D Printer Test Prints: Which Ones Actually Tell You Something
What to look for The test models are free. What you need is a way to read them and a filament that…
3D Printer Bed Temperature: Settings by Material, and Why Yours Reads Wrong
Short answer PLA 55 to 60 degC, PETG 75 to 85, ABS 95 to 110, ASA 90 to 110, TPU 40 to…
How to Calibrate a 3D Printer: The Order That Stops You Going in Circles
Each calibration step assumes the previous one is already right. Doing them out of order is why tuning feels endless.
The Calibration Cube: What It Actually Measures, and in What Order
A 20 mm cube measures the whole chain at once, so a wrong number tells you little unless you calibrate in the right order first.
Bed levelling and mesh compensation
A mesh corrects for a plate that is not flat. It cannot correct for a plate that is dirty or a nozzle that is not clean.
Input shaper and resonance compensation explained
What it corrects, what it cannot, and why running it lets you keep speed without ringing.
