Colour print app
Is the colorprint application open-source with everything else you have?
Issue
---------
When I print a single item and run it thru the app to switch colours at different layers I noticed that most times it would leave a blob of filament where it entered back into the print (after the colour change). My solution to this was to place a dummy object at the top right of the main object, I noticed that colour changes always exited and entered at that top right area. For a single prints, this solved the issue. Filament blobs were deposited on that dummy object and the main one was perfect.
However, my theory was thrown out once I added more than "one" main object on the plate. It appears that the colour change exited/entered at different spots - not the top-right. Thus my dummy object didn't make any difference.
From reading the forum posts and examining the g-code, I can see what gets injected to perform this colour change operation. I was curious if your existing application is open-source so I can add some logic to always exit at a known location (and allow me to place a dummy object to collect blobs).
If the app isn't open-source, do you mind if I write my own (in say C#) that injects the needed g-code for colour changes.
Thanks.

Hi Steve
First I would say that I don't get any blobs when using the filament change feature. What temperature are you printing at?
The "Colorprint" software and online option are not open source. However, there really is no need to write a program to install the "M600" command into the code at the correct height.
Because Colorprint only works with Slic3r-generated GCode, and I don't use Slic3r, I simply edit the GCode with Notepad++ and add the M600 where it is required.
The advantage of this is that I can add a second line (if required) to move the nozzle to a location other than the finish of the previous layer.

Thanks. Printing at normal PLA 210/50.
Agreed its as easy as adding the M600 command.

Those temps are what I use.
However, I do not follow the instructions regarding filament change. When the nozzle moves back to resume the print, I hold the extruded filament and as the Z Axis lowers, I pull the excess filament away.
