Well I have had a go, and it does not work for me. Both print from and upload to. It might be because I am using sailfish - I'm not sure.
When trying to upload, after it tells me the base file name can't be longer than 8 characters, it then rates the build platform and tries to extrude from the cold extruders - still at home position. Then starts making really weird noises.
When I try to print from SD card, I can see my folders but the software fails to enter them.
I have tried with Replicator 1 clones. Sailfish 7.7
Not that I am bothered - never used it anyway. Just thought I would try.
