There is also this thing which can help (assuming the bed is the same size): http://www.thingiverse.com/thing:131656 I use a pipe cleaner rather than a wire in my solidoodle 2 sized version: http://www.thingiverse.com/thing:176227

Something like this should work

G21; set mm units
G28 ;home all axis
G90; set absolute coordinates
G92 E0; reset extruder distance
M104 S195; set extruder temp and start heating
G1 X145 Y145 F3000 ; move to back right corner
G1 Z0.05 F200 ;move platform close to nozzle
G1 E5 ;extrude anchor
G1 X10 F12000 ; move towards the back left as fast as firmware permits
G1 Z5 F300 ;move platform down 5mm
G92 E0; reset extruder distance
G1 Z[first_layer_height] F200 ;move platform close to nozzle

Yep you're going to want to change the start code. I'll try and find a link or do a search for start code.

Clean extruder at start?

Hey guys,

Just got the SD4 and I have a question. I tried searching first but couldn't really find a solution so I apologize in advance if this has been covered before.

When I start a print the extruder moves to the center of the bed. That's great if it weren't for the fact that it leaves a drop of filament there while it waits for the print to start.

I played around with a MakerBot a few months ago and I think I remember that the MakerBot deposited a bit of filament before it started printing. Would that be a solution? Is this something I could add with some start code?

Any other solutions?

Thanks!
Serge
