We received our GRID II Dual extruder at work yesterday. I installed the latest ReplicatorG software and Python 2.7 according to the poorly written instructions that came with the printer. I leveled the build platform without too much problem. When it came time to add the filament I was able to load the right filament roll, but it seems the machine doesn’t recognize that there is a second extruder on it and the display on the printer never shows anything about a left extruder. It never heats up and the extruder stepper motor never turns on to accept the 1.75mm filament I am trying to feed into it. I confirmed that the ReplicatorG machine setting shows MBOT Cube Dual. I could not find any other setting that would allow me to enable a second extruder. I’m thinking I may need to reload or update the firmware. Anybody know of any other way to get this thing to recognize the 2nd extruder?
Next item: I was able to run the test print just using the single extruder and the tall twisted box seemed to print fine. But when I went to print a second item from the SD card the build platform shot up and ran into the extruder head. What is causing this to happen? I’ve confirmed that the build platform magnets are sitting within the respective counter bored areas of the platform arm.
One more thing: It seems that the model of printer that I received is not entirely clear to me. The label on the back of the printer says MBOT Grid II. The label on the box it came in says MBOT Cube II. The poorly written instruction manual references both. ReplicatorG software machine setting indicates MBOT Cube dual. The printer frame is black metal, not wood. Does it matter?
