Rep1 Single Starting Script Bad...

[crazyhamsales]

The starting script for the Makerbot Rep 1 Single is wrong, it doesn't behave correctly.

It homes then it sends the extruder to the front left, after heating up it just extrudes some plastic into the air then it goes in to start printing and makes a mess of the first layer. Unlike the Rep 1 Dual starting script the commands to print the purge line across the bed and wipe were left out. Here is a correct starting script that fixes this.

; **** Replicator 1 single start.gcode ****
M73 P0 ; enable build progress
G162 X Y F3000 ; home XY maximum
G161 Z F1200 ; home Z minimum
G92 Z-5 ; set Z to -5
G1 Z0 ; move Z to 0
G161 Z F100 ; home Z slowly
M132 X Y Z A B ; recall home offsets
G1 X-120 Y-70 Z30 F9000 ; move to wait position off table
G130 X20 Y20 Z20 A20 B20 ; lower stepper Vrefs while heating
M126 S[fan_speed_pwm]
M140 S[bed0_temperature] T0
M134 T0 ; stabilize bed temperature
M104 S[extruder0_temperature] T0
M133 T0 ; stabilize extruder temperature
G130 X127 Y127 Z40 A127 B127 ; default stepper Vrefs
G92 A0 ; zero extruder
G1 X100 Y-70 F9000 ; Move to front right corner of bed
G1 Z0.3 F6000 ; Move down to purge
G1 X-90 Y-70 E24 F2000 ; Extrude a line of filament across the front edge of the bed
