Topic: Overextrusion - Creatbot DX3
Hi guys,
I'm in a pickle and need your expert advice.
I've been printing this small part that attaches to a DC motor and I can't seem to get it right.
I figured out that the printer is over-extruding, so I went and calibrated the E step. Indeed the step count needed to be reduced. I pushed the changes to EEPROM using Matter Control as told by the internet.
I print again and the part still looks over-extruded. I try and reduce the material flow to 80%, it looks better from the outside, but you can clearly see that the layers are actually separated. The dimensions are now OK, I can mount it on the shaft of the DC motor, but since it's now a bit hollow, it can't hold any torque (it slips). Any ideas what to do? Is the temperature still to high?
- the printer is claiming I'm printing at 180°C
- using 3DE Premium PLA, 1.75mm
- 0.4mm nozzle
- 55°C heat bed temp.
- 100% infill
- 0,11mm layer
- print speed 1500,0mm/min (outline - reduced to 80%)
Have a look:
The one on the right is printed using calibrated E-step, the left one also has flow reduced to 80%.
See the layer separation on the left one due to reduced material flow.
Thanks in advance!
