most likely an early flashforge creator, with a 'pro' conversion kit.

Best slicer is flashprint from flashforge.
select 'creator pro' from the machine list.

It will not work with cura or most of the other common slicers, as it uses a weird x3g file format and NOT g-code.

Good machines.
I've got an old one on the shelf.
My very first 3d printer in fact.

Now while it is probably a flashforge, at the time there were a number of companies churning varying quality versions of this printer out by the thousand.

ctc being the main culprit for low quality, high production.

This type of machine is most often called a 'replicator clone' as it's a direct copy of a makerbot replicator - befor they came to their senses and stopped being opensource.

hope that helps. :-)

I could tell more from a front on photo.
