Zesty Tech Nimble and retraction issues/re-engaging issues
-
@fcwilt As of now I still need the pressure advance to maintain a good print. However over the holidays I have been working on redesigning some components and implementing a 40mm noctua fan for my heat sink. once I have it all thrown together I'll try no pressure advance and see where that lands me.

I'm just jumping back into this 3d printer adventure, printer being down the last 6 months.
I have a zesty nimble, and volcano using 0.8 nozzle and am using PETG.
I have yet to find a good combo of settings to get my prints to where I want.
I have also just started playing with Pressure advance. Using the calibration print that is in another thread with the python script to adjust it, It tells me I need 0.17 pressure advance.This then makes my prints extremely slow, so I have upped the jerk from the recommended 40 to 80 and 100.
I'm no longer sure the correct methodology for calibration with every new variable.
The above mentioned print is great for calibrating Pressure advance, but what is a good methodology/calibration for acceleration, and jerk ? -
Hi,
I use a Nimble with a .4 nozzle on a delta.
I have not used pressure advance as it works fine without.

Dakota, I have the exact same issue as you with my Nimble and using simplify3D. The print in your video is a mirror of my prints. Did you get it sorted, if so please can you share your settings?

Seems like most of you have a very high pressure advance. I run a Zesty Nimble on a Hypercube Evolution with a 0.6 mm E3D Volcano hotend. Sweet spot seems to be somewhere around 0.01-0.03 depending on how flexible the filament is.
I usually run 2 mm retraction at 40 mm/s, seems to work good for the Volcano.
I created this script to generate test files for pressure advance calibration if you would like to try:
