I am sorry! - D3D/RRF now working

[mrehorstdmd]

A couple things:

At what speed/acceleration are these printed? A single 20 mm cube is too small to print by itself at reasonable speed/acceleration without a print cooler because the nozzle keeps putting down fresh plastic on still-hot plastic from the previous layer. Try printing two or three cubes, separated by a few cm in one go.

Cura defaults to 2.85 mm filament diameter and will grossly under extrude if you don't change the setting in the custom printer set-up (machine settings, extruder tab). The same value also shows up as the default diameter in the material section, even if you select a "generic" material, and can't be changed unless you set up a custom material. When you set up custom material, be sure to check the bed and extruder temperatures.

@mrehorstdmd

Thanks for helping out - I am lost

I am printing them exactly same settings as on the ramps - same filament everything. The extrusion is taken care of now as it was wrong at first in Cura 341 - but not my later samples

I am running 2000/20 in acc/jerk and 50mms with 10s minimum layer time to ensure cooling between nozzle touch

Why does the ramps controller handle it and not the duet? Let me try printing 2 cubes to see if it helps

Here are some samples with different settings: I understand the XY not being all that great with no fan but the corners should be same as on ramps no?

@pro3d do a temp tower. As said before the same temps from ramps and Duet can by different in real world.

[pro3d]

It does appear to be the temp yes. Printing two at the time did improve - these at 1/32 I0

Now the corners are fine

I have some retraction calibration to do - thanks again and sorry for being a pain in the world cup

So here is the cube with a layer fan at 60mms

It is very good so I just need to figure out what caused the skip. The bed is almost floating so might be that or due to motor skip. Not sure. I did tighten my belts

Here is one at 50mms
