second color dosen't stick

Post by daveapplemotors »

I have printed a few logos: FIAT, FIAT Abarth and Oakland Raiders. All three of them have trouble when i switch to white as second color. ABS doesn't do very well at all. PLA sticks better but I don't get a good first or second layer. I use this bit of G-code to switch filaments:

G1 F2280 X140.941 Y134.264 E8679.46851
;LAYER:46


;TYPE:CUSTOM
M83
M107 ;fan off
M117 Filament Change ;LCD "Filament Change"
G1 E-1.000000 F6000
G1 Z15.000000 F300
G1 X150.000000 Y0.000000 F3000
M84 E0
M0
G1 X25 f6000
G28 X Y
G1 E1.000000 F6000
G1 E-1.000000 F6000
G1 F2280 X140.941 Y134.264 Z7.100000 F3000
G1 E1.000000 F6000
G1 F3000
M82
G1 F2400 E8679.46851
M106 S125 ;fan back on 50%
M117 Oakland Raiders ;back to printing
G1 F2400 E8675.46851
G1 Z7.100
G0 f6000 X86.714 Y78.243 Z7.100

Any ideas how I can make the second color work better?
