It was definitely worked on, I just loaded 2.5 beta today. Now it comes down and squashes the prime prime pile with the carriage.
Here is the unmodified GCODE around the prime extrude for nozzle 1 which in the case of this print was after the prime pile and brim was printed in PVA from Nozzle 2:
(Please note I moved the Nozzle 1 prime location so that I could see it better on the camera)
T0
G92 E0
M109 S245
M104 T1 S0
G0 F5000 X213 Y207 Z0.27
G0 X162 Y6
G0 F15000 X162 Y6 Z2
G280
G1 F1500 E-6.5
G0 F5000 X162 Y16 Z0.27
It is the last line shown above that moves the carriage in the Y direction 10mm from the prime pile and sits the carriage back down in it. if it just would have gone to X112 before sitting back down to Z0.27 it would have been fine, It'd be even better if they put a 2 second dwell in there for the nozzle have time to ooze onto the build plate.
So the Gcode would then be:
T0
G92 E0
M109 S245
M104 T1 S0
G0 F5000 X213 Y207 Z0.27
G0 X162 Y6
G0 F15000 X162 Y6 Z2
G280
G1 F1500 E-6.5
G0 F5000 X112 Y6
G0 Z0.27
G4 P2000
I CAN edit the GCODE but it would be awesome if there was no edit required to trust printing without having to run to the machine if a prime pile gets picked up.
Also adding a short dwell after the nozzle 2 prime would be awesome too. I even added a move to z30 then a -50mm Y move then move to z2.27 with a 2 second dwell, this worked awesome to get the ooze of PVA to attach to the build plate.
