I am looking at buying a PowerSpec 3d pro but have a few questions that I haven't been able to find the answers to.

First of all, the quick question, can the Pro print PETG material?

Now for the main question. I know that the Power Spec Pro is open source but can slicer be used with it? I have read mixed reviews that day no, yes but it takes a lot of work/modification etc. And I want to know if I can slice with Slicer, save to an SD card and the plug in said SD card and print directly from there. Can anyone guide me through this question with some answers?

Thanks,
