Multi-Color Printing

Hello!

I have recently been experimenting with multi-colored printing on my single extruder RepRap Prusa I3. I have been successful in doing this by using a plugin for Cura which at a specified Z-height, the extruder will raise and move to a predefined position, allowing you to insert a different filament. The problem, though is that I have a very short amount of time to complete the swap before all the stepper motors will deactivate. This causes problems because If the carriage is moved, the extruder will not return to the print at the correct position. You could possibly rehome the x-axis, but that still provides some inaccuracy with two different homings. Is there a way in Marlin firmware to say extend the time before the steppers deactivate?

The easiest way is Repetier Host. You can insert in your gcode a '@pause", anywhere. While you in pause-mode you can send any gcode to your printer.

Sorry, just read to fast...

In config_adv.h:
234 #define DEFAULT_STEPPER_DEACTIVE_TIME 60

I run my parts usually with Pronterface or an SD card. If I add the '@pause' command, will that show in pronterface as paused as well? to then continue the print would I hit resume in pronterface? I'll have to give it a test, but I think the motors would still deactivate after so long of inactivity.

This is a Repetier Host function.

Anyway, hope you read my edited hint. Just put the time from 60 to 600 or 900 (15min).

Great! i'll check that out. I just wasn't sure where that setting might be located. This will be much easier than having to manually modify the g-code each time. Thanks!
