I have a D-232. Very pleased with it. I mostly print with PETG. I have updated to the current version of MatterControl (2.0.0.10074). I still get a blob at the end of a print--but only when print from an SD card on the Viki 2. The same print is fine when I print with the computer connected. I've found that the nozzle doesn't "home" after the print is finished. Filament continues to extrude and creates the blob at the end of printing. Again, this only happens when printing from SD.
Also, no presets for PETG? I made my own, so no problem. But it's nice to start from a preset baseline.
