I had a X1C and its PA system doesn't truly work. Users managed to break into its MQTT output to find out it was not working at all but setting the default 0.02 which is set within START_GCODE. And not least, X1C lidar system was released as a flow calibration which is doesn't do, and PA which it doesn't truly work. Any filament will print "just fine" with PA 0.02. I had the lidar disabled in my printer to save time and preventing its print from taking space, I got a LDO Trident 300mm and miss absolutely nothing, totally different beast.

Really nice work. Pressure (linear) advance is one of the hardest things to get just right, and there's lots of room for improvement. For example, it might not be a linear relationship between speed and pressure, and it could also benefit from some lookahead. We'll keep doing our part to make it better, and research like yours is going to be really helpful to that project.

I'm on a quest to build the ultimate tool head and this is going to bring it to the next level. Very good stuff! I wonder if you could get better results using different build plates by printing basically a raft that has been ironed and then print the lines to be scanned on top of that. A bit excessive and might defeat the purpose a bit, but it could be interesting for people using exotic print surfaces not conducive to laser clarity.

Great to see an Open Source approach to this! Bambu uses the same idea (line laser plus camera) for calibrating extrusion. It would probably be little effort to add extrusion width calibration to this too. And it should be a reasonably simple job to implement this for Marlin (which calls it "Linear Advance" but it's pretty much the same idea) too, maybe as an OctoPrint plugin? I expect this will become the standard way to calibrate printers, and I imagine there might also be cheap nozzle-cams suitable for this coming from China soon.

Effective. And so much potential with so many obvious easy QoL improvements that anyone can make to the code today (even before actually having the equipment for testing). For instance, iterative/quick collapse by measuring after each calibration line (or 1 - 3 lines) and adjusting based on too much/little pressure. By making smart adjustments after each line we can quickly make coarse changes to the correct values and then finer changes once closer to the range. We can probably turn this into a binary search, the middle will likely be dynamicly defined with (eg. no less than 3 lines mandatory with a middle value, too high, and too low within printer precision threshold or a single line with a score threshold would be necessary. Precision threshold is more dynamic but would require increasing the testing range in order to get measurably too high/low values to verify we found the center). May or may not be able to do this in one pass as well (not sure if we can scan while printing or if the acceleration will have to much of an affect on the camera between fps and rolling shutter).

3 Thoughts: 1. This might lead to the realization of pre-emptive pressure advance, it's obvious that PA on it's own still isn't enough, it needs to have a pre-emptive kick one way or the other to have a truly clean line during acceleration changes. The timing of that kick it already gives, obviously isn't in the right place, a missing time component that will likely vary with each meltzone and pressure chamber size. Maybe one day we'll get that deviation to true 0. 2. Automated stringing and retraction calibrations? 3. As the laser is triangulating depth, you could then use this to figure out the build-plate depth, the laser line itself would need to be tuned to very square, or software corrections for uneven skew and lense distortion.

Great work! I assume you tried doing the same thing but by just taking a photograph of the test pattern and running it through a similar process. If you did try that, why did it not work? It seems (on the surface) that it would be a much faster process, than having to scan each line with the laser and camera setup. You might have to deal with some parallax and/or tilted plane issues with the camera, but I believe there are algorithms that already do that. Just curious.
@mowcius Жыл бұрын
That's much more dependent on lighting conditions, bed, and filament colour, whereas shining a (comparatively) high powered beam of light onto both the bed and filament is much easier to detect. You could probably get pretty close with a well controlled setup and a high resolution camera, but there would be more processing involved and you'd almost certainly end up with noisier data.
@MisterkeTube Жыл бұрын
I'm wondering whether PA cannot be tuned in a totally different way. As explained, PA is to compensate the delay between filament moving on the input side and pressure causing plastic to move out at the nozzle end. Would it not make more sense to just measure this delay by ex. measuring the output pressure using a load-cell and timing how long a change at the input takes to affect the measurement on the load cell? If the load cell measures upward pressure on the printhead (as the Mk4 seems to support), then the PA value could even be measured and corrected throughout the print.

That way, it could replace the priming line with this, and then auto calibrate advance before each print.
