Thanks. I did not dig into the Gcode lines to see it was a display vs actual bug.

Attached are the 3MF and Code for a One at a time print. The 3MF shows the print sequence correctly as two groups printed One AT A Time (Sequentially), while the Gcode ignores all that and prints the jobs as All At Once. ZPTRAY02-01.00.02-10.3mf ZPTRAY02-01.00.02-10.gcode

I have two case where when I generate the GCode in Cura 4.9.0 and 4.9.1, the resulting GCode path does not match the Cura path. Printing on a Modix Big Meter with Duet3D2 WiFi controller (RepRap not Merlin). This bug is pretty concerning as it makes me question the resulting GCode. One example is printing multiple parts one at a time. I Cura this show's the sequence and nozzle path correctly, one part followed bay another followed by another. But when I examine the GCode I see the GCODE has it as "All at Once" and has completely ignored the "One at a Time". I had though it was something to do with more recent addon but now examining a couple jobs I prepped but have not printed it predates those and is present in Cura 4.9.0. Are there and setting that interfere with the print sequence "One at a Time"? This one is pretty important as we have some large print batch jobs where we need the Print "One at a Time" functionality. Cura 3MF (Does not match the resulting GCode). Looks good an the Print Sequence is as desired Two Groups printing sequentially. CURA reopening the GCode from the 3MF. The GCode does not match the Cura tool path image. The Two groups print "All at once". The second case where I see that the GCode and Cura paths do not match is when I ran the Arc Welder add on for a part that has straight sides. It looks fine in Cura (3MF) but on examining the GCode I can clearly see that add on is not right for straight sided part or is very buggy. This oine is of less concern as it is just an Add-On that is not all that Important. Arc Welder Addon Enabled in 3MF in Cura (does not match resulting GCode). Looks pretty good CURA reopening the GCode with the Arc Welder Addon Enabled. The GCode does not match the Cura tool path image. I am not thinking the Arc Welder Add on is ready for Prime Time is this was the wrong part for it.
