CTC Blitzer Purge problem

[MacJack]

I am having a purge problem, my right extruder does just fine but when I select my left extruder it just makes a big blob , it does not move across the plate. Here is my scripts
left side
G92 A0 B0 ; Zero extruders
M135 T1 ; Load left extruder offsets
G1 X-100 Y-68 F9000 ; Move to front left corner of bed
G1 Z0.3 F6000 ; Move down to purge
G1 X90 Y-68 E24 F2000 ; Extrude a line of filament across the front edge of the bed
G1 X100 Y-68 F180 ; Wait for ooze
G1 X110 Y-68 F5000 ; Fast wipe

right side
G92 A0 B0 ; Zero extruders
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
G1 X-100 Y-70 F180 ; Wait for ooze
G1 X-110 Y-70 F5000 ; Fast wipe

what am I doing wrong

This script doesn't instruct the printer to perform a stationary purge.

Can you please goto Help > Configuration Assistant and load the original profile for your printer before slicing again and trying to print with the left extruder?

OK I will try that and post results as soon as I can. Thank you for assisting a newbie.

it still made a blob , does not move across the front edge of build plate.
