I have the MK3 all setup but cannot get it to load filament into the stock extruder to start the print. Do I need to edit the G code to send the filament a bit further into the extruder?
Also, will the tool change G code auto load a filament if there aren’t any loaded currently at the beginning of a print?
I undertook this project knowing it would be a project, but it would be nice if there were more resources out there to get going. I feel like I’m missing a lot of knowledge even though I mostly understand what is going on.
So, everything is done in GCode, so in order to autoload (which we do), the starting position for each filament must be known... Which is always 1" before the Y adapter in each tube. At the end of the print, you can unload (using our same unload code from the auto generated GCode) to make sure that when it finishes, it puts it back into a good starting position.
As for sending the filament a bit further, the GCode will automatically start the extruder for the last inch of 3DChameleon loading... But it is your job to tune the time so that it is perfect. There are two ways to do that... Edit the G4 commands (which is a "wait" command, with S or P... Seconds or Milliseconds) or shorten the tube between the Y and the extruder. Either will accomplish the same thing.
As for resources, make sure you watch all my videos in the installation of playlist... There's lots to learn from them.
Good question, I’ve ran into the same issue. ‘That first step after getting it all set up is critical to feeling accomplished. Are you able to see if the filament has reached the gear on your stock extruder? If so, then what I’ve done is created a ‘test’ print to get the stock extruder moving long enough that it starts printing. I have also tried loading filament too, but that did not seem to help.
