Very slow printing Duet Wifi on Am8
-
Do you happen to be using mesh grid compensation? Your Z jerk is quite low (only 0.2mm/s) and that could be limiting the speed of XY moves as it has to slowly adjust the height of Z. Try increasing it to 60 (1mm/s) and see if it improves.
Can you run an M122 and post the results?

@phaedrux Good catch (about the mesh compensation and slow Z speed).

Hello.
Thx for looking into this with me.
Mesh compensation? Again, some studying to do, I guess

I guess I'm not running any grid compensation as I do not have a bed-level-sensor (yet)
Might be something with my slicer ... (Slic3r Prusa Edition). The probleem seems less when slicing with cura... But that would very weird.

Can you explain to me where you read this value?
Do you mean Acceleration? So "M201 Z200"? Changing this to a higher value?Or is it about M566?
Thx!

Not really. There are all sorts of speed settings in each slicer and each one will only do what you tell it to. Did you check to see if moves via the web console are at the correct speed? If so, then the problem is likely to be the speeds that were used to slice the model. In Slic3r, look in the "Print Settings" tab, then under "Speed". What are the various speeds set too?

He means instantaneous speed change. But as you aren't using any form of flatness compensation, the Z axis won't be moving so don't worry about - that's not the reason for your problem.

You could post a gcode file that has been sliced with Slic3r and we could see all of the settings slic3r has used since it saves a copy of all it's settings at the end of every file.

@deckingman
Indeed, moving via de webconsole seems to function ok. Homing is happening at normal speed.Print Speed settings:
I'll check those, ... but it now uses the standard settings that came with the latest firm- and software :sIt has to be SlicerPE as the AM8 now prints Ok when using Cura for slicing.
-
@ludodg standard settings for which firmware and software?
