Running PETG on Cube3

[TommyDee]

Nice. What were the pause commands it sent out for the filament change?

[mperroud]

I just wait for the print to reach the required layer, then pause the print and do the filament change. I have installed the BTB extruder mod. Then, with the help of a screwdriver, I remove the filament and load the new one.

[TommyDee]

Cool. I added a G4 P60 to know when to hit 'pause'. I was hoping they had a more formal tool change vector to analyse.

Did it work with that command? I use simplify3d and I could not generate automatic pauses

[TommyDee]

The command worked to start the timer in a wait state. You use the "Pause" button on the screen and once the 60 seconds are up, it goes and pauses like normal. It keeps you from having to catch the very moment you want to pause the print.

Being that the .cube3 commands are highly stand-alone in structure; you could splice the PLA half of the print separated by a G4 P60 and completed with the PETG slicer file. As long as one filament type ends and the other begins, you simply put the first part of the PLA file with the last part of the PETG file. All the rules for the slicer are obeyed according to the printer. BuddyBu's editor will make fast work of that if S3D doesn't.

Have you tried using M226 to pause the printer until ESC key is pressed?

[TommyDee]

I never have but that can be very useful if you want to change the filament in the middle of the print.

I assume that you have to be running the Cube print desktop app to print files? I wonder if M226 has a pause length so that you could add a delay of like 2 minutes.

Yes, I am running the Cube Print app in Windows 10. I usually copy files to the USB drive rather than use WiFi just because I have had problems with the wifi disconnecting.

I haven't found a delay parameter, but I haven't looked and wouldn't expect one since the function is to pause until a user input, I think a time delay would be superfluous.

Maybe not superfluous if you are printing from USB.

But yeah, I can see if you are interactively printing, then it makes sense to have it based on user input.
