Low Speed for 3d Printing application

I haven't tested since i switched to 2.8, but when i was running 2.7 with XYZA config. it run WAY slower, i could hear the motors taking each single corner for every block making up a curve.
The difference between XYZA and XYWZ was really HUGE.
I'd really like to go back to XYZA (the graphic preview is completely messed up, and so are the keyboard shorcuts) but i need to be sure that it works first.
Now the machine runs super fast, the only issue is the lack of pressure advance which is a standard feature in new printers. I wonder if anyone found a way to implement a similar system in linuxcnc.

Probably doable using external offsets and some coding, best done as a comp (component).
There were some attempts to do something similar for plasma cutting, but it got forgotten since it is mostly used for round shapes on plasma and that got in part solved with a wizard.
If you happen to bump into a good explanation on pressure advance, please link it here.

There are some news about this TP solution with ABC blending, please?

Sorry, nothing.

Sorry to hijack the topic, but what are the chances of having a 3D printing section of the forum and is anyone here interested in it?
 

Can you setup an additive manufacturing/3D printing section for the forums? 3D printing gets confused with just FFF/FDM printers. Then we can have sub sections for SLS, SLA, etc

No i can not, sorry.

It looks like you (or someone) figured it out.

Yup, Jeff added that yesterday.
