OG, I'm not too familiar with the Replicator 2, however my Malyan M180 is very similar in the way it works and indeed I use the Makerbot Desktop replicator 2 setup in preference to Cura to save x3g files to an SD card. Saving gcode files to the SD card works but the printer doesn't recognise them, just the x3g ones.

There shouldn't be any problem though, the process is the same: save the file to the SD card, put he SD card in the printer, tell the printer to print it. You can always keep a gcode version on your computer if you want to though.

If you have your computer connected to your printer via USB then you should be able to rpint straight to the 3D printer from Makerbot Desktop. A note of caution here is that any interruption to the USB transmission can ruin a print and the print from SD card is usually the recommended method.

I'd be surprised if this is true? Once the PC has transferred the files to the controller on the printer, then you should be able to disconnect or even shutdown the PC. That's what I do with my Up Plus, anyway.

I can see your point Andy, though the manual (hah!) that came with my printer advises the comment I made. I suppose it could be dependent on the memory capacity of the printer, a large print being buffered and therefore in need of the connection being maintained, as is the case with normal printers.

Most of the 3D printer controllers don't take the whole file in one go.. the PC sends it serially down the USB cable, awaiting 'OK' acknowledgements as it goes, so if you pull the cable the print will stop.

It is only if you transfer the file to the SD card attached to the controller that you can remove the USB once the controller has it, the print then progresses from the SD card

As a matter of interest which YouTube video was most helpful OG?

Are you using dual heads for alternate materials in each head (like PLA in one, ABS in the other) or to print support material from one and the 'body' material from the other? Do any of the dual head machines support water soluble support material?

I have (intermittent) access to a single print head Ultimaker and am toying with getting something myself (but can't see getting an Ultimaker budget past domestic financial control). Dual head seem like a good idea if possible within budget, if only to dedicate each to a particular material.

hi

the answer is yes to all your questions, it is very easy to change filament even during print
