Error running GPXui with Slic3r gcode

[wirlybird]

Hi all,

New here and I hope this is an ok place for my issue.

I am trying to run a start script in slic3r for my QIDI Tech-1 (rep1 dual clone).
When I run the GPXui to convert to x3g I get the following errors.  This is the output text I get.  When I try the print the start script actions aren't even close to what I would assume they should be.  For example the bed drops way down, the prime is in mid air etc.

I added the start script below.  Thanks for anyt help!!

Ok, I figured out the "syntax error" it is setting the first layer height by a percentage instead of absolute.  Now my first layer is still an issue.  If I can even get anything to stick it looks very under extruded but the prime line prints good.

I have now been able to get the start script and Slic3r working.  Still need to tune Slic3r but gaining slowly.

Here is my working start script.  Feel free to comment or advise improvements!!

; begin

M73 P0 ; tell the firmware we're starting a build

G130 X118 Y118 Z40 A118 B118 ; set vref's to default

; set temps

M140 S[first_layer_bed_temperature] ; set bed temp, don't wait

M104 S[first_layer_temperature_0] T1 ; set nozzle temp, don't wait

; home and set coordinates

T0 ; home on the right extruder

G90 ;  set positioning to absolute

G28 X Y Z ; home XYZ at default home feedrates

; home Z again slowly to give more consistent first layer height

G92 X0 Y0 Z0 A0 B0 ; define this as Z=0, the other coords are technically unnecessary but x3g requires them so gpx will make some up

G1 Z5 ; move the platform 5mm down

G28 Z F500 ; so we can home z again slowly

M132 X Y Z  ; Recall stored home offsets

; wait for heat up

G1 X110 Y-72 Z30 F3300 ; move to waiting position (front right corner of print bed)

M116 ; wait for target temperatures to be reached. GPX only, RepG doesn't understand

; purge and wipe
G130 X127 Y127 Z40 A127 B127 ; Default stepper Vrefs

;G92 E0 ; set current extruder position as 0 so that E15 below makes sense
G92 A0 B0 ; Zero extruders
M135 T1 ; Load left extruder offsets

G1 X110 Y-70 Z[first_layer_height] F2400.0 ; move to just on the bed

G1 X110 Y70 E15 F1200.000 ; extrude a line of filament along the right edge of the bed
G1 Z1 F100 ; Lift
;G92 E0 ; set E to 0 again because the slicer's next extrusion is relative to this 0
G92 A0 B0 ; Zero extruders
M73 P1 ; @body (notify GPX body has started)
