Build progress way off

[dennisjm]

I don't know exactly where this bug lies. Maybe it's the fault of S3D or maybe some other issue, but it's consistent.
Anyway, attached pic is of the build progress immediately after the heaters warm up and the print is actually starting. Here is my start gcode...

T0 ; set primary extruder
M103 ; extruder off
M73 P0 ; enable build progress
M70 P2 (Simplify3D)
G162 X Y F3000 ; home XY minimum
G161 Z F1200 ; home Z minimum
G92 Z-5 ; set Z to -5
G1 Z0.0 ; move Z to 0
G161 Z F100 ; home Z slowly
M132 X Y Z A B ; load current position from EPROM
G90; set positioning to absolute
G1 X100 Y73 Z30; move Z to waiting height
G1 X-100 Y-73 Z30 F14000; move to waiting position (front left corner of print bed)
G130 X0 Y0 A0 B0; set stepper motor vref to lower value while heating
M6 T0; wait for bed and extruder to heat up
G130 X127 Y127 A127 B127; set stepper motor vref to defaults
M108 T0 R3; set extruder speed
G92 E0; set E to 0
G90; use absolute coordinates
M73 P0; reset build progress to 0
M73 P1 ;@body (notify GPX body has started)

Printer is Flashforge Creator X.

This happens worse the smaller the print. i.e. the smaller the print the larger the build percentage is at the start of the actual printing. So for this print it says 39%. If I print a large print it might say 4 or 5%, not as far off but not 0.

In playing around with generating x3g files manually, I discovered it's the -p parameter.

gpx ... -p ...

If you leave that out, the progress indicator starts at 0% and goes to 100% exactly like the gcode tells it to.

Simple fix.
