I think it's supposed to do that to reduce time spent idle while heating up to reduce print time.

No one? I'm desperate for help!

It's still playing up so I'm going to roll back to an earlier version to see if it's something with cura. When swapping to T1 it still will duplicate the m109 command but it retracts before going to print. With T0 it won't duplicate the M109 but won't retract. Really strange, I made another post but no reply yet.

Ah, OK then, I think the issue is mostly at tool change but I will check now and see how it goes. Thank you again!

Do you mean machine start or tool start?
It looks great but I'll check what it does at a tool change to see if it fixes the issue there as well. Get back to you soon.

Hi Everyone,
I have a Leapfrog Bolt Pro IDEX printer and I am having trouble with the tool change g code.
Issue 1 is that even though I have a M109 and M104 command at the start of the start gcode it will still generate a second set of commands which are after my nozzle wipe movements so this causes oozing before moving to print. I am not sure why it is doing it, I am running Cura master version 20200703.
Issue 2 is I am not sure how to get the extruder to retract after the purge/wipe movements, move to start the next layer and then prime the retracted amount. It seems to do it at the very start of the the print before the skirt but not at the tool change and my brain is now fried from trying to figure this out. I have attached the project and the generated g code from a file and the following is my start gcode for my right extruder (left is the same except for x movement and tool selection)
M109 S{material_print_temperature}
M104 T1 S175
G1 Y-32 F12000 ; move to wipe Y position
G91 ; set to relative
G1 E15 F200 ; extrude 15mm
G4 S2
G92 E0 ;zero extruder
G1 X290 F12000 ; perform wipe sequence
G1 X367 F12000
G1 X290 F12000
If anyone can fix this for me I will love you for ever and of course happy to pay for the help if it takes up too much time.

No problem, thanks again! Hopefully you can find something with the M104/M109 codes and I will create a new post for help with the tool change.

I have attached it now, The main issues I am having are the M109 and M104 replication but some advice on start gcode for each extruder to do a retract after the purge/wipe, move to print position then prime back retracted amount before printing would also be amazing. It seems to do it in the G code at the start before the skirt but won't do it after a tool change, also if this takes up a significant amount of you time please let me know your pay pal so I can pay you for your time.

Thanks so much, I changed my start gcode so now it performs better but it still sets M109 twice when selecting T1 extruder. I uninstalled Cura completely and installed the latest mater build you shared in the link on this thread but still no luck. Any other ideas?

Hi,
I would just like to start off by saying thank you for all the work you have done, I am having a similar issue but instead it is with an IDEX system.
When I check the generated G Code files it puts a M109 and M 104 in after the start G Code which also has a M109 and M104 command. Since I have an IDEX machine (Leapfrog Bolt Pro) I want it to heat up, purge, wipe then start printing. My start G Code looks like this (I am still not sure how to set print and stand by temps as per slicer settings so I put it in manually)
M109 S252
M104 T1 S175
G1 Y-33 F12000 ; move to wipe Y position

G92 E0 ;zero extruder
G1 X290 F12000 ; perform wipe sequence
G1 X367 F12000
G1 X290 F12000
The gcode generated after slicing does this at a tool change

That's awesome thanks so much for the response!
