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.
The motor you are using is rated at 1.5A, so 500mA is rather a low current for it. Try 1000mA.

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.
