I purchased my 3D Chameleon a couple of months ago, and haven't really been able to get it to work. My T1 seems to skip a whole lot, so I've tried to use T2 and T3 instead. However, whether I'm manually pushing the button to load and unload, or if the g-code does it when trying to print, it seems that the shorter press to unload the filament actually loads it, and the longer press to load the filament actually unloads it.
So I'm in a position where T0 works as intended, T1 skips and is unusable, and T2 and T3 don't work as intended. Instead of multi-color, I still only have access to print one color.
What can I do to fix these issues?
Thanks for the response! I popped the extruder motor out, and sure enough that grub screw was loose. I tightened it and that seemed to fix T1 (and T3, but I didn't play with that one much). I must've screwed up the g-code, so I'll re-generate that and see if it'll fix T2 and T3 while printing.
First off, there might be nothing wrong at all with the 2nd and 3rd extruders, because they are actually on the opposite side of the extruder drive gear, so their logic is reversed. The directions don't move the extruder forward or reverse, rather, they tell it to spin the motor clockwise or counter-clockwise... so a 3.5 and 5.5 second drive it clockwise and counter-clockwise... which for extruders 0 and 1, load and unload... but for 2 and 3, unload and load.
Our automatically generated gcode automatically does that for you.
As for extruder #1 skipping, can you confirm that the lower drive gear is actually turning? Does it pull and then pause for a second, then pull again, when you run it? If so, you can remove the 4 screws holding in the extruder motor and pull it out the bottom, then check that the Allen (grub) screw is fully engaged... we've seen some where that lower one becomes loose and allows that gear to spin freely. If that's the case, just tighten it back up using your small Allen key that came with the printer. I might add, if the this is the problem, you'll see the same thing on #3, as they share the same drive gear..
