Zesty Nimble configuration
I've been working to get my zesty nimble set up on my Rostock Max V2, and I've got everything together.
The extruder motor is a KL17H248-15-4A, and I'm using a Duet v0.85.
Using the initial settings that Zesty put out for setup with a 1.8degree stepper motor, I'm seeing the extruder put out about 5% of what it should be. It's turning, and it's turning in the right direction, but I haven't been able to get it to the right speeds, as with the way it currently is, I'd need a steps/mm around 67000 (WRONG hahaha).
Here is my stepper section from my config file:
M350 E16:16:16:16:16:16 I1 ;1/16th Microstepping on Extruder motor
M92 X80 Y80 Z80 E2700 ; Set axis steps/mm
M906 X1000 Y1000 Z1000 E500:500:500:500:500:500 ; Set motor currents (mA); set each extruder explicitly
M906 I100 ; Set motor idle factor to 100% while testing so they don't idle at all
M201 X1000 Y1000 Z1000 E120 ; Accelerations (mm/s^2) Set all E-motors the same
M203 X20000 Y20000 Z20000 E1200 ; Maximum speeds (mm/min) Set all E-motors the same
M566 X1200 Y1200 Z1200 E60 ; Maximum instant speed changes mm/minute. Set all E-motors the same
I'm wondering if it's just something simple that I'm missing here?
Thanks for any help.

I've got a nimble running on my rostock max, it's on a duet wifi 1.02 but if you don't have it going by the time I get off work I'll share my config file and what motor it's got, might be of some use
Appreciated, the motor current was too low, and in addition, I found a G92 command down lower in my config file that was overwriting the line I had above, those two things got me off and running.
Appreciate the help.

I'd suggest a smaller motor if you'll be fine-tuning the thing. The bigger the stepper, the harder it is to get faster snappier retractions. I personally ended up settling on a 17HS08-1004S at 500 mA, solved my retraction problems for good.
Mike! Noted, I'll look into that once I start seeing the tuning issues arise, thanks!

@mike Just want to know what retraction speed are you using?

@jackal around 45 mm/s, I've had some trouble with the recommended 30.
