I let it print slow now, again stopped at exactly the same place, I now have 4 cubes with mcu shotdown on exactly the same spots, all three printed at different speeds… attached last g-code OrcaCube.gcode.zip (399.0 KB) crash is after layer 56, I see everything that should be printed on layer 56 …

thanks, didn’t see that one … looks like extruder can’t keep up this i=100 seems like a problem as it is much lower than 264 on the benchmark page … this makes this printer unusable for me if this is the case :frowning: will have to check more … Dumping stepper 'extruder' (mcu) 2359 queue_step: que…

I just figured out that extruder has planetary gearbox … maybe pressure advance is trying to move it too fast … is there a way to limit this somewhere? what I don’t get is when I graph it I do not see the problem [image] but printing this cube, 20+ mins in I see this: [image] what happens tha…

You can set a feeder velocity and acceleration under the extruder section.

[image] LifeOfBrian: velocity and acceleration under the extruder s max_extrude_only_velocity or something eslse ? I do not see anything else but this looks like retractions only nothing wrt pressure advance / input shaping ?

[printer] kinematics: cartesian max_velocity: 300 max_accel: 12000 max_accel_to_decel:5000 [extruder] ... max_extrude_only_velocity:2000 max_extrude_only_accel:10000 I’d be surprised that an entry level bed-slinger can reliably work with these settings. But since it is SOVOL’s default, they should…

I am up for any suggestions :slight_smile: but I doubt acceleration can cause this… max velocity otoh can I understand but still I do not see anywhere any high velocity in my g-code … I can’t see why it breaks the klipper there, always at the same spot, not sure if it’s a bug in slicer or klipper …

Try something along the lines of: [printer] kinematics: cartesian max_velocity: 300 max_accel: 6000 #max_accel_to_decel: 5000 [extruder] ... #max_extrude_only_velocity: 2000 max_extrude_only_accel: 1500 and you also might want to review your slicer settings, since this: ; external perimeters ext…

why does that sound goofy it is 0.8mm nozzle ? I could go with 0.96 line but this 0.85 gave decent results… I was going to calibrate PETG to see what proper extrusion with with this 0.8mm nozzle would be but ended up not being able to print a damn cube :frowning: anyhow something weird is going on…
