Purging G-Code

I was watching a few videos online and saw that the CEL Robox has a purge system for clearing the extruder of plastic. You could of course do this with your hand but I have made the G-Code specific for clearing exactly 100mm of filament so you can do an extruder calibration along side the purge.

I don't really use the cancel function in Cura because it is faster to close the window and reopen it. So in the script.py I changed this:

addButton(0, 200, 255, 'Cancel', cancelPrint)

to this:

addButton(0, 200, 255, 'Purge', sendGCode, " M104 S190; M104 S190; G28; G29; M109 S190; G1 Z2 E5; G1 F1000 X5 E45; G1 E50; G1 F5000 Y5; G1 F1000 E55; G1 X220 E95; G1 E100; G1 Z5; G28; G92 E0")

(Can't use M104 S{print_temperature} for some reason, if you need a temp higher than 190c change S190 to S(desired temp).

You end up with a pretty purge that looks like this:

 

Any way you could convert this to a purge script to start a print? I'm using S3D and it currently has:

G28 ; home all axes
G1 Z5 F5000 ; lift Z by 5mm
M565 Z-0.6 ; set the offset for auto-leveling mechanism
G29 ; run auto-level

Purging before the print would really be ideal for me.

 

Here's the G-Code that purges the system:

M104 S190; Set Heat to 190
G28; Home All
G29; Auto Level
M109 S190; Heat and Wait
G1 Z2 E5; Extrude and Raise
G1 F1000 X5 E45; Move and Extrude
G1 E50; Extrude in place
G1 F5000 Y5; Move to Y5
G1 F1000 E55; Extrude in place
G1 X220 E95; Move and Extrude
G1 E100; Extrude in place
G1 F5000 E95; Retract 5mm
G1 Z5; Move Up 5mm
G28; Home All
G92 E0; Zero Extruder

 

Thanks, but this doesn't actually purge the nozzle in my system for some reason. It goes through the motions but nothing comes out.

 

The temperature might be too low. Increase M104S190 to M104S210

 

I use Simplify3D, so my temps are set before my start script. I was using this instead:

G28 ; home all axes
G1 Z5 F5000 ; lift Z by 5mm
M565 Z-0.6 ; set the offset for auto-leveling mechanism
G29 ; run auto-level
G1 E5; Extrude
G1 F1000 X5 E45; Move and Extrude
G1 E50; Extrude in place
G1 F5000 Y5; Move to Y5
G1 F1000 E55; Extrude in place
G1 X220 E95; Move and Extrude
G1 E100; Extrude in place

When using "G1 Z2 E5; Extrude and Raise" it never lowered and just extruded in mid aid, making a mess, so I set it to "G1 E5; Extrude". I also removed the retract because S3D already retracts before starting the print. I would like it to raise between extrudes and before starting the print, but I can figure that out on my own if need be.

Thanks for the help so far by the way!
