To me it is not clear why it measuring with both nozzles even if the print would be done with one only. After disabling of autoleveling and manual calibration everything is working fine.

While I was trying to use brand new 0.8 or 0.25 cores on the second head, the printer were showing error 999 asking for reboot. I have figured out that the source of the issue is that the printhead is missing the head switching bay even after calibration. here is a question if somebody successfully used two cores with different diameter.

I cannot understand why it is working so bad. I get constantly an error that a difference between the print cores exceed expected value even if I print with one core. (why?) I have disabled the automated leveling with Ultituner.

1 year later.. it is the same.

no, I was not sure if it is needed.

Hi, I have just updated UMS5 with latest Firmware, 7.1.0 and found that I am unable to switch off the active leveling.

I would suggest to use an universal tool allowing not only disabling of active leveling but also something more. I have just tried and it is working

Smithy, big thanks for a tool I was looking for. If I may wish an improvement, it would be an exe with options inside for a simple mouse click.

Das Problem lag an zweitem Print Core. Erst nach 2. Justage hat funktioniert, danke.

Darf ich mal fragen wie man mit zwei Filamenten druckt? Ist es eine Baugruppe wo alle Teile separat sind und für die man den Kopf zuweisen kann?

Ich habe das gleiche Problem mit neuem UM5 bei der Verwendung von 1mm DDP, die ich auf die Glasscheibe gelegt habe. Hat jemand hinbekommen beim UM5 auf DDP zu drucken?

I am wondering if it would be possible to overlap table and print core heating. The temperature rise speed is known for both, so starting the print core heating before the table will reach target temperature will save some time for users. Also to me is not clear why the table warpage measurement cannot be done while heating. I believe the thermal expansion over last 10°C will not bring any additional bending. Also what is annoying, in case I have interrupted the printing while preparing I need to run to the printer just to confirm on touchscreen that I don't want to repeat the print. Could this question pop up remotely or better completely skipped? If needed I can start a print of last model from printer menu.

@philippe44 observing the same on a brand new UM S5. Printed a pattern of 4 parts approx 110x80x6 mm. Material ABS from BASF, used UHU glue, bed temperature as per datasheet. All four parts do have a lifted left rear corner. Wondering if it could be related to by air manager created air circulation inside the box.

in my case a switch off for 10 Minutes helped only.
