Layer Count Error

Large Claw.gcode

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.
