Out of the blue my A6 printer displays a ERR MAXTEMP BED error and shows about 100 degrees on the bed even when just powered on.
A quick thermistor check shows that it's working properly : about 80 kOhm at room temperature, similar to other units…

What could cause that?
When linear_advance (v1.5) is "off" (M900 K0) - everything is uniform and smooth, only corners are protruding as expected.
When it is "on", I get these horizontal defects. My calibrated K-value is 2, I am getting same…

Does matching whole Z-motor steps for layer height actually matter on Ender 3?
This question asks about computing the fundamental layer height unit for full Z-motor steps, on the basis of a theory that layer thickness can be inconsistent if the height is at different micro-stepping positions on different layers. The specific…

How to calculate the proper layer height multiples?
We all know, that the best layer hight is, when you have multiples of full steps. If it is not, sometimes steps get skipped and end up bad layer-to-layer adhesion when one height step missed a tiny bit and then the next catches up, creating an…

Should I comment out the code for what I am not testing when loading the test firmware for Ramps 1.4?
You may want to use this code to test all the electronics before
installing any of the suggested firmwares.
I'm planning on:
Flashing the test firmware onto the Arduino Mega 2560, then unplugging it from the USB.
Connecting RAMPS 1.4
Connecting…

Why are delta bots so finicky?
I've had my anycubic kossel for a good while now, and whenever I print something, it seems like it falls out of calibration very quickly. The biggest example is that the prints tend to scale up as the print progresses, or maybe the print starts to…

How to post-process G-code to make prints faster using splines and arcs?
Recently (in 2017) there was a paper that got some publicity by researchers who are using a B spline algorithm to reduce vibrations in 3D printers. But before them, a B Spline implementation seems to have been first been made open-source by an alias…

Do Cura's self-crossing infill patterns account for excess material from self-crossing?
As far as I can tell, Cura's infill patterns which are self-crossing, such as triangles, don't do anything special to account for extruding material over the crossing points multiple times. In theory this should produce either a blob around the…

What actual dyes are used in filaments?
I've seen several questions about dyes in regards to food-safety, with no conclusive answers, as well as anecdotes on the RepRap wiki about how the mechanical properties of dyed PLA tend to vary by color. The general unsatisfactory answer is that…

Can a short-circuited heat bed be salvaged?
I was working on my printer when something metallic came into contact with the pcb. I smelled smoke and quickly unplugged the printer. Anyway, this is the result and, of course, the heat bed won't heat.
Can this be salvaged or should I toss it and…
