Feature request: Change Filamant Button in Pronterface

[3daybreaker]

Hi All, I am new on this forum and not sure how to submit a feature request, but this is my idea:

A button (Change FIlament) in the console.
Hitting the button during a print will have this effect:

1. Button caption and function will change in "continue"
2. Pronterface will remember where it was in the Gcode
3. Pronterface will pause printing
4. The exruder carriage will home in X and Y direction (no change in -Z-)
   5 Temperature of hotend and bed stay unchanged
5. Motors ill be set off
6. Pronterface will allow manual extrude button to be used

This will give me the opportunaty to change the filament, manual extrude plastic until the old stuff has been extruded and the new color is there

8. Than I will hit the 'continue' button and the cariage will return to the position where the pause was activated
9. Print will continue

You'll get the point ?

Currently, I can not do this easy, as pausing the printer will droop at the spot and when I change filament at that location, the object will become a mess.
If I manual mover the head, I can not reposition to the point of origin.

Please comment or ad on this idea.

I believe you should be able to

1. hit Pause
2. move the head to the side
3. change the filament
4. extrude
5. home X, home Y
6. hit Resume

(As long as your GCODE has absolute measurement.)

Hi, thanks for your comment.
I use Slic3r and the 'relative e-distances' is NOT checked.
Does that mean that absolute measurement is in place ?

I had no idea that resume would pick-up the last position after moving the head.
How can I check in the Gcode whether it is absolute ? What code should I see ?

btw: how strong is your believe ? I 'd better check this on a small test and not after 4 hours of print i guess :-)

I will experiment

thanks Thomas

E distances is relative/absolute for the extrusion.

To check if your distances are absolute, search G90 in the beginning of the gcode.

I'm pretty sure that the printer will continue in the right position, but I'm unsure if extruding while paused won't make the printer reverse some amount of plastics while resuming (if the extrusion is also absolute).

I recommend to slice a 1cm to 1cm to 1cm box and try it.

Hi Hroncok,

I just paused a print today, moved the head and extruded some plastic.
Then I homed de x & Y and resumed. It went all well, so ... Thanks for the tip.
This will increase my multi-color experiments :-)

Hi Miro, 
  you were correct.
  Please see my experiment with the Thingiverse 'Panic' item:http://www.thingiverse.com/make:52122

Guess we can close this one ?
