Topic: Changing Filament on Da Vinci 1.0

I have had my Da Vinci 1.0 for a few months now. I am using Simplify3D but stock 1.1J firmware.

I have looked at gcode and, br=eing a programmer by trade, I understand it and am comfortable modifying it.

I would like to print some multicolored objects. I understand the concept of pausing the printer, changing the filament, and resuming the print.

I would like to know the best strategy to do this.

Should I modify the gcode to pause where I want a color change? How do I do this? What are the commands commonly used for this?

Should I just pause the printer from the front panel, change the filament, and resume printing?

I just would like advice on what other people are doing.

TIA

Steven

No reason to modify the gcode. You can pause, remove the filament by depressing the arm, push the new filament in until it comes out the other side, and resume. Just Don't remove the cartridge, leave it in and feed the new cartridge in from the top. Only downside is the filament counter thinks you are using the installed filament so it will read lower than actual. I do it all the time. http://i1194.photobucket.com/albums/aa376/pbcrazy96/Mobile%20Uploads/image_zpszvmxpivq.jpg

I must be getting senile.  I have a DaVinci 1.0 and can't seem to find the arm that will release the filament.  Where do I look?

Re: Changing Filament on Da Vinci 1.0

The key concept is that as long as you don't move any of the axes by hand, and use the manual controls only (don't keep the nozzle over the print or it will burn it), the machine will resume printing where it left off--it will return the head to the next valid position in GCode. If you move it by hand, however, the machine won't know where it is and it will not resume printing in the correct spot. If you bump an endstop by mistake, this may also cause the printer to lose track of where it is (just depends on the firmware).

I don't know if the Da Vinci halts the motors on pause, but if it doesn't, you won't be able to move anything by hand anyway.

When facing the machine it is on the left side of the head just behind the the visible edge of the PCB where the two three pin harnesses connect. It is silver and you pull out on the top of it.

Printing since 2009 and still love it!
