Layer Count Error

[CCS86]

Completely different model, sliced with similar settings also registers as 5.00mm tall and 34 total layers. In reality it is 24mm tall and 159 layers.

Based on your start gcode it seems like it's picking up the G1 Z5 in your start gcode. Try changing that to be G1 Z5 ;E

Good call, I'll give that a try.

[CCS86]

That did it, thanks!

My layer count is way off. Its supposed to be 75 layers.

Maybe someone can tell me, what Im doing wrong.

35x35_0.4mm_nozzle_flowrate_calibration_0.2mm_PLA_RatRig V-Core Pro_23m.gcode

[Lanovar]

Ahh ok, now I understand.

Is ;E excluding that line from layer count?

[Lanovar]

So now Im down to 76 of the original 75 layers.

35x35_0.4mm_nozzle_flowrate_calibration_0.2mm_PLA_RatRig V-Core Pro_23m.gcode

I think the last wrong layer is the ";before layerchange" G1 Z0.200?!
My before layerchange section is empty in PrusaSlicer. Any tipps on how to fix that?

@Lanovar Add the ; E to this line in your start gcode: G0 Z5; Raise nozzle before move and add ; E to this line in your end gcode: G1 Z45.2 ; Move print head up

[Lanovar]

@Phaedrux I already did that, but one false layer is still left.
Maybe you could take a look at my second post?!

I think that G1 Z0.200 is the layer change.

;BEFORE_LAYER_CHANGE

G1 Z0.200 F12000.000
;AFTER_LAYER_CHANGE

That's before layer change, layer change, and after layer change. with before and after being blank.

But it also looks like you have Z hop on.

G1 Z0.400 F12000.000
G1 X150.000 Y167.279
G1 Z0.200

Z hop, travel, back to layer height.

And in your end gcode you have a z move, but you should make sure you're in G91 relative positioning mode before doing the Z move. That way you can move the extruder up above the print rather than to a fixed position (which may be inside the print).

;END_G_CODE

M400 ; wait for current moves to finish
M104 S0 ; turn off temperature
M140 S0 ; turn off heatbed
M107 ; turn off fan
G1 F1000.0 ;E set feed rate
G1 E-3 ;E - retract 3mm
G1 Z45.2 ;E - move extruder up
G1 X20 Y200 F3000 ;E - move extruder to X side
M84 X Y E0 ; disable motors

Yes I have, but does it count as a layerchange in DWI?

Actually Im using conditional G-Code in PrusaSlicer for that:

{if layer_z < max_print_height}G1 Z{z_offset+min(layer_z+30, max_print_height)}{endif} ;E - move extruder up

Isnt that kind of like switching to G91? Or am I misunderstanding what youre saying?

@Lanovar We've hijacked another persons resolved thread. I think it would be best if you created a new thread with your issue. Include your firmware and DWC version, the example gcode file, your homing file.

Yes that makes sense.
