duet 2.04 -> invalid model height with cura 4.3 sliced models

garyd9

Using cura 4.3.0 to slice and a duet wifi with firmware 2.04 (release), DWC is showing invalid model heights and layer counts in the model. For example, I've provided a google drive link to a sliced model that is 68.5mm high. However, the duet reports that it is only 1mm in height with five 0.2mm layers.

The problem is this line near the end of the file, which I expect comes from the ending script that you configured in Cura:

G1 Z+1 E-1 F1500 ; move Z up a bit retract filament even more

That line is confusing the file parser, which thinks that the +1 is the object height. Change the comment so that it starts with uppercase letter E, for example:

G1 Z+1 E-1 F1500 ; E move Z up a bit retract filament even more

then it will report correctly.

@garyd9 looks like Cura changed the tagging agin, unless this was working with an older version of DWC?

This problem has nothing to do with DWC, it's either a DSF or RRF problem. Are you using a Duet 2?

I'm not suggesting it's a DWC issue... (or pointing any fingers.) I just listed the symptoms as they appear (and DWC happens to be the "public face" of the duet firmware) as completely as possible. It is a duet2 (duet wifi.)

Other information not already explicitly provided: DWC is the version included with duet firmware 2.04(release), the duet board h/w version 1.04 (I think.)

I also understand that this likely won't get fixed before RRF3 (but the gcode is linked so that someone using RRF can check it.)

Tony, you moved this to the DWC section, but I don't think it's a DWC issue.

apologies, thought it was a DWC issue, moved back to general discussion!

Thank you, @dc42

I guess I was wrong about it not getting fixed before RRF3: Making that tiny edit resolves the mis-reported height. I'll have to play around with my ending script to clean it up. I'm not sure why I have an explicit 'plus' sign in the Z movement.

Are there any general rules I could follow in my own scripts to prevent confusing the parser?

Not really, the only gotcha is a Z movement in the ending script.
