Pattern Pressure Advance Calibration

Slightly off topic, I tried some retraction tuning using the "standard" two-towers type structure. The problem with all of them that I have seen is the towers are too small (typically 5 mm dia) and the plastic blobs a few layers into the print. Maybe my cooling is inadequate, but I think a larger tower size (maybe 20mm dia) that takes a little longer to print and allows a little more cooling to occur is probably a good idea, at least for a large nozzle. More experiments to follow.

@Ellis Would you be open to me using your script on my website to replace the current one ? www.advanced3dprinting.com is my site . Or i would love to have you post a blog article and you could put a tip link in it since i do get about 700-900 unique visitors a day so it should get you something in return .

All fine, or not?

@CrazyCreator following the instructions on the site, I would say you end up at 0.035 to 0.04.

@oliof stupid question ... in my config.g i have to disable the M572 or is overwritten from the g.code?

Ellis

@Robthide37 Sorry just saw this.
I would prefer to keep it on my site but you are welcome to link to it

Ellis

@oliof The tool will set your PA using M572 at each increment, and then set it back to the start value at the end. If you have your PA set before running the tool, it will override it.

See Saving Your Value once you settle on a value.

@Ellis Oh sure, I was just sharing my interpretation of the print results.

@oliof Sorry, meant to tag @CrazyCreator there!

@CCS86 good idea ...

here is the new one ...

i think 0,034 or 0,035 is the sweet spot.

oliof

@CrazyCreator yeah, 0.035 still gets my vote
