[3.3] E stepper issue
-
Hi,
I upgraded my running setup of the Duet 2 WiFi with 3.2.2 to 3.3 and now my stepper E (extruder) is behaving strange.
it seems to be to "week", like it would not get enough power.
all other steppers seems to work fine (X,Y,Z)is there anything what needs to get changed when changing from FW 3.2.2 to 3.2 in regards to the extruder stepper?
thanks a lot in advance for any help

@matt77 I can't think of anything that needs to be changed for 3.3 relating to the strength of extrusion.
Please try the following:
- Run M98 P"config.g" to see if there are any error messages. If there are errors in your config.g file then the way they are handled may have changed between 3.2.2 and 3.3.
- Send the following commands and post the responses:
M584
M906
M913
It may be that your system had developed a poor stepper motor connection (or just possible a partially-failed driver) coincidentally with the firmware upgrade.

This is the source of the heater 3 not found error. That command is no longer valid in RRF3 as you do not need to free up a pin to use it.

I'm not sure it matters, but it looks like you have a comma in the E value instead of a decimal place.

@phaedrux
Thanks for the hint. ill correct that and see if its already fixing the problem. -
The heater 3 error is gone, thanks @phaedrux to point this out.
the problem with the extruder stepper still persists.its really strange, with RRF 3.2.2 its all fine.
as soon as i'm migrating to 3.3 and extruding or retracting the stepper is so "week" that i can stop it from moving with my hand. without any force.its like its not getting enough power. but with v3.2.2 its all good.

M584
You have your drive mapping very late in your config.g. Maybe you've changed that already but:
"M584 must come earlier in config.g than any M350 and M906 commands. If it creates new axes, it must also be earlier than any M92, M201, M203, M208, M350, M566, M574, M667 and M669 commands."

@gixxerfast Good catch.
@Matt77 it may be worth getting a fresh config set from the config generator tool to use as a test comparison.
