Verbatim's BVOH is rated between 200-220°C.
The extrusion is fine so far.
For Raise3D's PLA the specs say 195-220°C...
Currently a test is running w. PLA@200°C and BVOH@205°C.
I also lowered the Bed to 50°C.
So far the print goes well.
But this object is not so complicated/does not have so very small details like the last one.
So adhesion is not that much of a problem here.
Unfortunately the wipe tower is "gone" already - it had a raised edge on the side which is pointed towards the model and got ripped off.
So the printer now "wipes" in the air. Seeing that answers one question - where do those strings com from?
Cause wiping "in the air" does not cut off the wipe-material. Instead, it is pulled to the printed object and sticks onto it.
I guess it makes sense to position the wipe tower a bit more far away from the object plus making it a bit bigger?
Regarding the shifting:
I have not seen that before nor after this test print.
Even at the moment the print goes fine and it's already way above the height of the shifted layer.
Strange thing is, that the offset is looking so clean, isn't it? Perfectly onto the X-axis.
If that was caused by a nozzle hit, one should be able to see evidence on the surface just before the shifted layer that there was something sticking before it has been pushed to the side?
And why did printing resume more or less nicely on the shifted part?
To me that does not sum up...
I just remembered that I recently tried to print a vase.
(wavevase from https://www.thingiverse.com/thing:983438
And that this print also failed and had some shifted layer as well
Just took it out of the plastic-waste and took a look.
The shift has taken place in a very similar height!
I did not recognize that earlier since the print was a complete disaster anyway.
There have certainly been some nozzle hits;-)
By the way, I can't find a good way to even slice this vase correctly.
In Cura it is either completely filled or does not have a bottom layer (so is open on top and on the bottom).
In IdeaMaker it has errors in the outline:
And you really see those in the print.
By the way - this is what you get in IdeaMaker when you slice the vase after scaling it to 50%:
...not the expected result, I'd say...
