3D printing forums

I know this subject has been discussed numerous times in the past, but a few things have changed now, with the M1 Macs.  And since cura is now supporting M1 Macs, what are the chances it will port across to the iPads ? Id be happy to pay for this app, as it will make my life a lot easier. I'm not sure how cura for Mac is coded, but if it's using native swift code it wouldn't be hard to port it across, as one of the new things about the m1 chips is it uses the same code base as iOS. It's hard to believe no one has created a slicer for iPad yet.

There are two fans on the print head, one blows through a vent to the nozzle.   I'm actually just trying another print as I type and both fans are blowing so they both seem to be functioning and the gcode probably switched one off at some point when I tried previously.   I just read an article which said that lower print speeds could increase stringing and blobbing and I had reduced the print speed believing the opposite might be true. However, I can say now that looking at the print in progress, increasing the speed to 100mm/s from 50mm/s has not improved anything.   Also, I reduced the nozzle temperature from 220°C to 200°C (I'm using PLA+ and the box says 190°C to 220°C and 220°C had worked okay). That didn't make any difference to the problem I am having but also introduced the problem of poor adhesion between layers - they were easy to peel apart. I am just trying at 210°C.

I'm trying to set up use of dual extrusion with a main material on extruder 1 and a support material on extruder 2, in Cura, for the Ultimaker S5. But the support it wants to generate is ridiculously excessive. In the support settings if I tell it to use extruder 1 (same as model material) for support it generates a pretty sensible pattern under all the overhangs sharper than a given angle. But when I change this single box to tell it to use extruder 2 it generates support all up the outside of the model even where there are no overhanging features to support. It encases almost everything in support for no good reason, I am not considering some ultra slim tower of a model which would risk toppling if not given support all around. How can I stop it doing this and just have support generated, using the second extruder, in the same configuration as it would be in when using a single extruder only. Thank you

I disabled the integrated GPU and now Cura crashes but not Windows.    i added a new log file as it contained more data in this case.     cura.log

der hat keine Beine. Er ist auf einem Aluprofiltisch gelagert. Der schwingt schon genug hin und her bei der Rucklerei, dass ich Angst um die Verschraubung der Profile habe   Ich werde mal versuchen an der Beschleunigung was zu stellen. Bisher habe ich von all den Dingern die Finger gelassen. Und zukünftig verzichte ich auf Infill bzw. mache die Wandstärke dicker, so dass kein Infill entsteht.     Screenshots von was? Von der Schüttelei? Oder von den Strecken auf denen es passiert. Sind einfach senkrechte "Wände" z.B. eines Kastens.
