I received my GMax last week and I am pretty pleased with it. The lack of a COMPREHENSIVE operations guide however is a source of frustration and is forcing me to turn to the forum for some much needed help.
How is the second extruder loaded and controlled? I was able to load the first extruder and have successfully printed out several things of various sizes with really good quality. But when I navigate through the LCD menus, prepare->Axis-->(etc) I can only see one extruder entry and that controls the first extruder. It wasn't readily apparent how to load the first extruder when I loaded the filament for the first time - I stumbled on the first extruder entry and figured that was it and it was. But there is absolutely no entry anywhere for the second extruder. I am selecting the .1 mm (smallest degree of travel) from the LCD menu tree for the move distance and then scroll down and see the first extruder. (it just says extruder - it does not enumerate it. ie. list it as extruder1). So I can move and load filament there for the first. But there is no mention of a second extruder anywhere.
My main info screen shows the temps of the two thermistors but I realize those are two separate sensors/pcs of hardware and are connected to the ramps board independently of the extruder steppers. But it's interesting to note, the firmware knows there are two thermistors so logic would make you assume there would be the same number of extruders shown in the prepare sub menus. - but I guess that would be too easy
I tried flashing with the different dual firmware packages to see if maybe the cause was the latest release but none of the dual extruder firmware (past or present) provides the ability to control the second extruder via the LCD screen. My Config.h file appears correct (it shows the # of extruders as 2) At this stage, I don't want to pour through all of the marlin code to figure out whats going on.
I'm obviously missing something that should be a no-brainer. Any help would be greatly appreciated.
Thanks in advance,
Larry
