Bottom layer thicker and Excess nozzle extrude at HOMING position
October 20, 2016 01:45AM
Hi All!!!

I am trying to take models. At HOMING position its excess extruding. I have been used CURA earlier but now its extruding nealy 3-4mm at 200-205 degrees. Also getting thick layers for 2-3 layer at bottom. Please help out with this.

G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G1 Z15.0 F9000 ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F9000 ; Put printing message on LCD screen
M 117 Printing...

Have you looked at your Slicer settings check if you are printing with a raft.

I'll say it again too you need to turn your temps down and print at a slower speed for the first few layers to get good adhesion.

PLA doesn't need to be extruded at 205c plus for PLS I think you need to be printing with the fan on.

Give this a watch.
