Thanks for keep us informed. 👍

wegen dem anderen Tread? 🙂

This is something where the Cura team can improve the software as this problem is well known and often reported since Adaptive Layer was implemented. 🙂 I don't want to complain, but find it remarkable that Slic3r can do that easily (they implement it 2017). Cura implement it, but isn't able to summarize layer heights correctly. I know, easy to say, but how long exist Cura 4? And there is no time and/or priority to correct this software failure - the only thing that a FDM-Printer can easily achieve in exactness and the slicer isn't able to do it. I am still hoping that someone from the development team take this issue and repair it. Because this is showstopper for technical prints where is the need for minimum one exact measurement.

There is even more to do for controlling the bed heater. Bang-Bang-Control or PID-Control and setting PWM frequency for the SSR. https://duet3d.dozuki.com/Wiki/Choosing_a_bed_heater#Section_Bed_heater_driven_using_a_Solid_State_Relay

Statt Raft ist Brim ebenfalls eine gute Variante. Bei PETG auf die Bett-Temperatur, Druckgeschwindigkeit für den ersten Layer und Lüfter achten. Für den 1. Layer setze die Druckgeschwindigkeit eher in Richtung Hälfte der normalen Druckgeschwindigkeit und Lüfter aus. Bei problematischen Teilen (wie z. B. spitze Winkel und 90° Ecken) kann man sich bei eigenen Konstruktionen kleine Eselsohren als Brim-Ersatz hinzufügen. Das ist sehr hilfreich, falls ein Brim für saubere Außenkanten problematisch ist. Bezüglich Tisch gibt es ebenfalls noch einen weiteren Punkt, die Rollen betreffend (zumindest bei früheren Modellen), dort wandern die Kugellager in den Rollen nach innen weil man an einem passenden Spacer gespart hat. Dies führt dann ebenfalls zu einem wackelnden Tisch, insbesondere, wenn die Platte heiß ist und die Wärme mit der Zeit dort wirkt. Als Interimslösung kann man die Miniaturkugellager aus der Rolle nehmen und mit sehr sparsam dosiertem Sekundenkleber auf der Innenseite der Rolle wieder verkleben. Oder neue Open-build Rollen kaufen - die funktionieren dann garantiert, da sie einen passenden Spacer zwischen den Lagern haben.

You are setting the maximum variation to .16 and that is the problem. 🙂 What does this mean for your layer hight? You are advising Cura explicit to variate your normal layer hight of 0.2 mm between 0.36 mm (0.2 mm + 0.16 mm) and 0.04 mm (0.2 mm - 0.16 mm). So said, if you don't want to have a smaller max layer hight, you need to reduce this value. In addition you maybe want also change the original layer hight to a value that match to your needs. E.g. when you want a max layer hight of 0.2 mm and a max. variation of +/- 0.5 mm the matching regular layer hight should be 0.15 mm. Edit: Oh, @ghostkeeper was a bit faster. 🙂

The problem shouldn't come from the SSR. 220 V Silicone heating pad? This looks more like the temperature is over- and undershooting too much. How is your setup for temperature control?

Disable Use Tower will help to solve this problem/error with support.

There are 3 adjustment screws for Use Adaptive Layers: There is also a very beneficially handy plugin called Settings Guide from @ghostkeeper with a detailed description for these and most other parameters.

A little bit late, but thanks for your feedback. Your observation is the same I and other users of my printers have seen. And it is wrong with 4.6.2 too as well as the retract issue I reported on may 13 here. Anyway, I had a lot of hard discussions regarding Cura last and this and even more this year (I'm supporting some small companies here in my local area). We took a decision and changed the slicer since beginning May.

Thanks for your really helpful plugins 👍

Evtl. Gewinde für Kunstoffbehälter (DIN 6063-2)?

@maht, any new cognitions on this?

Your welcome.

Works fine once you setup a user defined application in Fusion360. This is a german gui, but with the pic you should be able to configure it for you. Simply follow the steps 1 to 8. And keep in mind that you need to repeat this first 7 steps with each new major Cura release.

I don't know if it will help you. There is more than one value you can set for adjusting flow rates. Maybe this will give you more possibilities to fine tune this.

Ah, I just forget a last thing: Is it maybe possible to change special characters (in this case german umlauts) in gcode descriptions in the same way as for filenames (or in its asci equivalent like ü to ue)? It shouldn't be a complex problem to do this automatically in a future version 🙂

Hi @maht, Thanks for your response. I "measure" this with the z-values in the gcode (regarding hight). I can give you a link for the CAD file, if needed. I had some serious quality complains with parts from the last two versions. I was out of ideas and finally start to analyze the gcode of some projects with technical parts. Where to find it in code: when you look from starting line 90380 (last but one layer): G1 F1350 X103.051 Y63.825 E1319.56458 <--line 90380 G0 F7200 X103.617 Y63.825 G1 F1350 X104.228 Y63.214 E1319.60661 G1 X104.298 Y63.144 G1 F2400 E1317.40661 <--line 90384 retract G1 F300 Z25.45 <-- line 90385 move head 1mm up ;MESH:NONMESH G0 F7200 X66.412 Y73.713 Z25.45 ;TIME_ELAPSED:10663.609631 ;LAYER:138 ;MESH:B??gel Kunstoff.stl G0 X66.412 Y73.713 Z25.75 ;TYPE:WALL-OUTER G1 F300 Z24.75 <-- line 90393 start last layer, but last layer should be 25.00 mm G1 F2400 E1319.60661 G1 F1350 X66.399 Y74.474 E1319.64363 G1 X66.399 Y88.495 E1320.32565 G1 X53.799 Y88.495 E1320.93855 This happen in all models I had test after I recognize this and I was wondering why parts starts not fitting correct. You can verify the hight with deselecting [Use Adaptive Layers] in the project file and generating the new gcode file. In that version the body hight is correct. I came to this because if have some complex parts where multiple level highs have to match the accuracy of 0.1 mm. My prints usually fulfill this accuracy in hight, but as I recognize now, not for gcode generated from at least with the last two versions (beta and 4.61) of Cura. The other point is right in the beginning with retract: M82 ;absolute extrusion mode <--line 10 M140 S81.0 ;Start heating bed M104 S235 T0 ;Start heating extruder M190 S81.0 ;Wait for bed to reach temp before proceeding M109 S235 T0 ;Wait for extruder to reach temp before proceeding G28 ;Home G1 Z15.0 F6000 ;Move the platform down 15mm G92 E0 G1 F200 E3 G92 E0 G92 E0 <--line 20, not part of any start or end gcode G92 E0 <--line 21, not part of any start or end gcode G1 F2400 E-2.2 <--line 22 retract, not part of any start or end gcode ;LAYER_COUNT:140 ;LAYER:0 M107 G1 F300 Z1.2 G0 F3600 X107.139 Y45.552 Z1.2 ;TYPE:SKIRT G1 F300 Z0.2 G1 F2400 E0 <--line 30 where is the compensation of retract from line 22 ?? G1 F1350 X107.629 Y45.678 E0.01641 Now imagine what happen if your retract is far longer than 2.2 mm and you are using no skirt or the part is small and so on. This will result in a damaged first layer (missing length of filament, no steady flow in the beginning of a first layer) In addition an little irritation starting line 20: There are too many "G92 E0". The extruder have no start and end gcode, but the engine put in these codes. In the end it do not matter but there shouldn't be any additional code if there is no reason for it.

Maybe there aren't a lot of enterprise user using the actual Cura version. (because of ws.reputation:1)

11 day's old and not even a comment. By the way, there is also a problem with retract and G92. A frustrated Cura user.

Not really strange. AV suites have to make as much as possible non critical false detections for showing a customer that they need those suites. It is how this kind of business work. 😉

Ha, you have "coated and disinfect" your self. Now you are save against all viruses too. 😉

I'm printing PETG at 235°C on glass with 81°C. Usually PETG will be printed between 230 to 250 (max). Normal PEFE tubes will as @gr5 mentioned degenerate faster at higher temps and should not heated up to 250°C because of toxic fumes, but these temps are usually not needed.

Why should deleting G92 E0 solve the problem?
