Yes of course, I just did an material unload, a load and a material change, it happens every time. The exported log is attached below. I did an export every time but only uploaded the latest one, if you need the other ones too, I can also upload these.
Hi, I have exactly the same problem with an Ultimaker S5 R1. The printhead does not corretly move to home after loading material 1 since firmware 8.1.0 and needs to be returned to home manually by the service menu.
Moreover the LED of Printcore 2 is not working since the update to version 8.x.x (not blue when cold and not organge when hot, LED2 is always off - it could also be defect, but is exactly the since the update to version 8.1.0 - in the photo from glx this could also be the case, because LED2 seems to be off).
In addition to the removal of really essential features (see other topics), there unfortunately seem to be several bugs in firmware 8. This is very disappointing, since the last firmware 7 (7.1.3) was working fine. I haven't had time to downgrade yet and still hope for an improved firmware 8 without those errors and recalled features.
@mscho, yeah one LED is off, but I have only printed with one material loaded since I updated to 8.x.x, so I didn't think much about it. The LED is also solid green after the material is loaded (instead of the usual blue-ish), they did change something on the LEDs tho (I did read it here: What do the different light colors mean on print cores? (makerbot.com) the note below says it can be different, so I guess something was changed here).
I think you cannot downgrade (at least not easily) after upgrading to an 8-version, that was mentioned in a release note of one of the updates.
yes, i cannot follow what this new firmware is doing, the lights are now just green, the second extruder has no lights even when its hot from the bed probing. The head parks on the right now after loading material, but on the left overwise.
Doesn't seem like these are intended changes ??
It is a bit difficult to troubleshoot this without the log files. Could you please share the log files from when this happened? You can find how to export the logs files here.
