Trommelschlumpf

Thanks or testing. For calibration reasons I'm trying to testprint...while I figured out the first-layer-problems... As soon as I could deal with it, the whole thing will be calibrated ;) I created an bug-report on github - maybe there somebody knows what to do: https://github.com/MarlinFirmware/Marlin/issues/20590

What does ABL mean? That's correct. First extruder has a .3mm nozzle, second a .4mm one. At the moment I'm only using the forsi one.

As far as I understand, all values are absolute. Does cura support relative z-values? Maybe this will work. I can imagine Marlin setting a safety-z-zero and a one-way (up only to avoid crashes on moving-down). So it starts printing where ever Z level is after leveling. Then it goes over to next z-value. As this is smaller than current z-level, it won't move down. Next layer, still z-level is too small...so all movements except Z do work. This might repeat until Z reached current z-level (which is 4.65mm). What do you think about this idea?

In fact it IS pushing plastic - but the raft prevents filamentflow. Next video Ill add a third camera for the extruder 🤣 When flow was 100% I could see the filament-hills around the nozzle...until there was no more filament coming out - because the 1.75mm was grinded to less than 0.5mm... so for the moment Im fine with 70% flow until my z-level problem is solved.

Did you try to copy&paste the link? For me it's working on two devices without any problem... The extruder is working on the lost layers. But I set the flow to 70% because at 100% the gear is grinding the filament (until it's unable to move it any further) while the nozzle is closed by the raft.. There is no air-printing. First it's printing the raft, then it slides on the top raft layer which prevents filament flow (imagine like the ironing feature) ...when z finally is greater than 4.65mm there is space for the filamentflow. But the extruder is always working. Parts printed on z > 4.65mm look fine. So on each of my prints the bottom 4.65mm are missing 😞

That didn't help 😞 I just recorded a small video of the printer's behavior: https://youtu.be/vQkE3Z16EZI Also I uploaded an archive: [url=http://www.digitalinventions.de/files/temp/IronBot_Cura_Marlin_Problem_first_4.65mm.zip]http://www.digitalinventions.de/files/temp/IronBot_Cura_Marlin_Problem_first_4.65mm.zip[/url] This file contains: -Marlin-config -Marlin-config_adv -screenshot cura-settings for printer (like start/end gcode) -3d object I sliced and printed -M503 marlin printer status -3mf cura-project-file -gcode-file Might the z-height of my printer in the config-file be the problem? When probing, you can see the values on the display. But I couldn't see 4.65mm anywhere except the M503 status home-offset (see M503 file: home offset). Here's the Marlin threat for my printer: https://reprap.org/forum/read.php?415,878907,879958#msg-879958 What else could I do?

Printing without raft is a bad idea at the moment....since my nozzle crashed into my BuildTak yesterday 😞 Funny, my start g-code looks like: So I just have to swap G28 and G29? Just starting a test now 😉

Here's the cura file 😉 remeshed_Spiral_Cube.3mf

Sure, gcode file of https://www.thingiverse.com/thing:2434091 is attached 😉 I generated the gcode using Cura as well as I did the same using Slic3r - both with the same result. Bottom layers are lost... CFFFP_remeshed_Spiral_Cube.gcode

No ideas? I would like to print the whole cube. Setting z=0 fails. Lifting the cube into the air doesnt work....so what might go wrong?

Since days Im searching a bug I noticed at my printer: After auto-leveling and printing the raft, My z-level is about 4.65mm. Looks like my Gcode starts at this z-level, so Im missing the bottom. Whats wrong? Is it a cura-sertting? For me it looks like after rafting there need to be done a z-level = 0. Or the model needs its z-level be relative, like: whereever you are (after rafting), go on, incremenz z and print.

Exactly, slicing works fine now 😉

I finally found "mesh fixes" "remove all holes" in cure - disabling this everything looks fine 😉

Hi, I would like to print this parts: https://www.thingiverse.com/thing:4401023 FreeCad shows this parts as they should be: But Cura places an infill: Which setting might I want to change? Also Id like to print one single of those parts. Is there an option I can cut the rest away?
