XL fw update

[3D Printing Tips and Tricks]

After waiting through a bunch of updates I went ahead and installed 6.1. They added a calibration at the end of the very long calibration list. This new one seems to test the X and y steppers (misnomers for a coreXY machine, just sayin) and then seems to calculate some kind of smoothing for traveling which makes it all less noisy. It seems to work, but it does nothing beyond making it quieter. So they put their developers on to doing this to catch up to Bambu which does something like it, yet they do nothing about the priming tower in ps.

Why are you using a prime tower? The beauty of the multi head XL is that you don't need the prime tower.

Unfortunately you still need it for PETG and the use case I can’t serve with current PS is four colors of PETG and pla for supports. PS blends the pla into the prime tower which then fails.

Please note there’s a big difference between a priming tower and a purge tower! Different purposes, different amount of waste material.

I am having success printing PETG w/ PLA supports. Used your retraction tip (actually bumped it up to 11.8) and brought my temps down. Great results, no wispy stringing while printing hatchbox PETG, overture PETG was quite wispy though.

The upgrade to the XL motor control algorithms makes the motors move more smoothly which quiets them down and reduces subtle artifacts in the printing. Smoother motion is a good thing. Steppers make noise because their torque has ripples which is not good for precision motion. Precisely controlling the waveforms can improve this.

It made zero difference to print quality for me..lts still very good to excellent.
