Automatischer Z Offest Abgleich funktioniert nicht mehr bzw manueller Z Offset wird vom Ultimaker abgebrochen.

[Ultimak3r 0]

Hallo,

mein Ultimaker 3, gerade mal 7 Monate alt, macht zicken. Je nach Einstellung führt er vor dem Druck die Kalibrierung des Z Offset aus und gestern war es mal wieder soweit. Leider hat er sich beschwerd das die Differenz zwischen PrintCore 1 und 2 zu groß wäre. Also alles überprüft düsen gereinigt. Ohne Erfolg. Nach einigen Druckversuchen und jedes mal neuem automatischen leveln, welches jedes Mal fehl geschlagen ist. Hatte ich einen Factory Reset durchgeführt. Jetzt mäöchte er gerne kalibrieren. Er fährt die Platte hoch und drückt sie gegen den Druckkopf viel stärker/länger als sonst, bricht dann ab fährt runter und startet von neuem, der Druckkopf bleibt aber an der selben Stelle. Dies macht er ein Paar Mal und bricht dann komplett ab. Im Display steht dann Active leveling correction failed ........ER22. Beim Manuellen Z Offset kann man ihn zwar auswählen. Im Display erscheint We will calibrate the Z offset with the calibration card. Der Kopf fährt in die rechte hintere Ecke und das wars, im display springt er dann wieder zurück auf Calibrate Z Offset. Hat das mit der Firmware zutun? Aktueller Stand 3.7.7.20170627. Hardware defekt Shunt Widerstand ?

DAnke für eure Hilfe im Voraus.

MfG

Manfred

Please check http://ultimaker.com/ER22

It would help to send the log files.

Use System -> Maintenance -> Diagnostics -> Dump logs to USB and send those files to us using something like WeTransfer.

Hello @Ultimak3r,

I did find something in the logs that looks wrong. But I'm not yet sure about the cause of it.

Can you do a http:///api/v1/printer/heads/0/extruders for me, with the Print Cores inserted that give the issue please?

Thanks in advance.

Also, make sure to do a manual or active bed leveling before starting the manual calibration of the Z offset.

The manual bed leveling would include the manual calibration of the Z offset.

See https://ultimaker.com/en/resources/23127-build-plate-leveling for more information.

Either way, some bed leveling data is needed before the calibrate Z offset can be run manually.

Hope this helps!

Hi Marco_TvM,

after i did the manual bed leveling i want to print soething and ofcourse the printer did the automalical Z offset again and it fail again. First the test with printcoare 2 looked okay but with printcore 1 it moved to the left backwrads corner and the print bed pushed the nozzel into the head and stopped. At the display was something like the difference between printcore 1 and 2 is to high. ER22. I switched of the automatical leveling and without that function i could print. But the problem is not really fixed. Any idea what it can be or which part i have to change?

Here the file which you asked for.

Please let me know if you need more informations for anylising that issue. BTW till friday i'm on a buisness trip and i will not have access to the printer.

Hi,

Some feedback: what we saw in the log (and in your post) is that the Z-nozzle offset procedure was run before active or manual bed leveling was executed.

In the next testing release this menu item will be removed, so only an active or manual bed leveling will set the Z offset.

Hi,

thanks for your feedback. Let's wait for the next release and see what will happen. In the moment the automatical Z Offset before printing doesn't work also after a manual bed leveling. I can print perfect results without it so i decided to switch it off.

One more question / feedback. I like the menu and how it works of the ultimaker3, but I always turn the wheel in the wrong direction that the bar in the menu is not moving in the direction I expect. Would it be possible to insert a option in the menu which inverts the direction of the menu wheel so everybody can decide which is the best for him.

Thanks alot.

best regards
