How to reproduce

I make a new Printer IDEX Snapmaker J1. If I use 2 colors the printer should make 2 purge lines at the beginning.

Start GCODE: {if total_toolchanges==0} T{initial_extruder} G92 E0 G1 F1200 X5 Z0.5 G1 F600 X100 E20 G1 F600 Z2 G92 E0 G1 F1200 E-6 {if initial_extruder==0}G0 X-20 F12000 ; park T0 {endif} {if initial_extruder==1}G0 X350 F12000 ; park T1 (old 345) ; park T0 {endif} {endif} {if total_toolchanges>0} T0 G92 E0 G1 F1200 X5 Z0.5 G1 F600 X100 E20 G1 F600 Z2 G92 E0 G1 F1200 E-6 G0 X-20 F12000 ; park T0 T1 G92 E0 G1 F1200 X295 Z0.5 G1 F600 X200 E20 G1 F600 Z2 G92 E0 G1 F1200 E-6 G0 X350 F12000 ; park T1 (old 345) {endif}

If there is 1 or more toolchanges the printer should do 2 purge lines. This only work if the wipe tower is enabled. If not, "total_toolchanges" didn't work. This was also a bug in prusa and is fixed since version 2.7.0.

You can try it with a default benchy, make some color lines in it and try to print...

Actual results

With wipetower = 2 purge lines (correct) Without wipetower = 1 purge line (NOT correct)

Expected results

With and without wipetower should the value of total_toolchanges be correct so I have 2 purge lines with and without wipetower! Screenshot_WithWipetowerTwoPurgeLines
