@chris94 When you just run G28, is then the z height correct?
When not, you have to adjust your z endstop (EDIT: or the bed with screws) -
@cosmowave yes if i just run the G28 in DWC then everything is fine
-
@chris94 What is the first z-height in your gcode? It should be your defined layerheight (e.g. 0.2)
-
@cosmowave dont mind the extra Z steps

G4 S20 ; Pause
G1 F100 Z0.8After your printhead moves to Z+5 you have a pause of 20 seconds!
I think you know that you have to wait 20s ? -
@cosmowave yes it is there to eyeball the initial distance so i can check where the coordinates are
-
@chris94 And this inital z height of 5mm is also too high? (at 10-13mm)
-
@cosmowave more or less yes. i can't really measure it. the picture was taken at a theoretical height of 0,3
-
@chris94 Do you have set a additional "bed surface"?
Can you post your config.g and if exists relevant macros please. -
@cosmowave i don't know what an additional bed surface would be so i don't think so.

@chris94 With additional "bed surface" i mean: in the slicer you can define a bed surface thickness (like an additional plate e.g. mirror on your bed). This thickness will be added to your z0
You are sure that your z endstop is 218.1mm above z0?
-
@cosmowave the z endstop is at the low end of my printer and this is the exact distance to the nozzle so yes, i am sure for now. like i said it's just for a quick and dirty print to make a video. there is no build surface set as far as i know (i am totally new to cura). btw thanks for taking your time
-
@chris94 When it's only for a quick and dirty, you can eventually set the G92 Z218.1 a bit lower?
-
@cosmowave i probably could but i'm a little bit scared that this could result in a crash as long as i dont know where the problem is coming from
-
@chris94 Yeah sure...
Can it be, that the z move in you gcode (G1 F100 Z0.8) is done relative instead of absolute.
But if this is the case, i don't know why...
But eventually you can hear/feel/see the little 0.8mm move? -
@cosmowave I don't understand this step either. its straight out of cura. i am currently setting up my simplify to see if it is a cura export wonder problem or something somewhere in the config
-
@chris94 What happens if you put a G90 in slicer startcode?
-
@cosmowave good question. i will try that when i am back at home
-
ok as far as i can see it isn't the slicer gcode. tried it with G90 but that did nothing. i cant see anything in the config, home or somewhere else where this "offset is coming from. If I use a macro with a G1 to go to Z0 it's not a problem, but as soon as I start a print ...
-
G28 ;Home G1 Z30 F3000 G1 X0 Y200 F600 G1 F600 Z10 G1 F100 Z0.8 G1 F900 X20 Y200 G1 F100 Z0.3i tried to use just a simple move after a home and i still get the offset and i can't figure out why. i could be blind but i am pretty shure that i did not configured something that trigges this offset. the only thing i know is that it looks like the offset is set at the first move after the G28
