if you don't have minicom running, kermit is your new friend for this sort of thing.

IIRC, in my inkscape "save as" extension that writes the modela file format, it asks you for your output dimensions, so we could probably change those numbers, and it _should_ scale the output to your desired print size and offset. I can play around with it later if need be. -- Matthew On 01/29/2011 08:00 AM, Ed Paradis wrote:Awesome! I figured that 'F' was 'Feedrate' and I tried changing it, but didn't get anywhere. I'm almost thinking that some sort of 'live' control software needs to be written to explore the settings. An inkscape template like the one for eggbot would also help. Also some sort of "unit to real life" conversion factor. ... Probably a lot of other things too. I'm going to go through this document.

Looks like we can change the XY feed rate with the F command. I think the default "preamble" from my inkscape-modela script sets vertical feed rate to 30, and XY feed rate also to 30. Not sure what units. You could try changing that in the header to see if that helps. -- Matthew On 01/14/2011 11:54 AM, Matthew Beckler wrote:Also, also, I just found a 47mb zip file of what looks like the original windows software for the modela.

If we can use it as a print server of sorts, than it'd be plenty fast, I think.At this point it might be the best we can do. All the "modela server" needs to do is to cat a text file out the printer's device. Tonight, I can probably whip up a quick daemon to listen on some random high port, and send the received file to the parallel port. That way we wouldn't need X or anything too fancy on the modela server. Does anyone have an adapter for old laptop hard drives, to connect them to USB or a regular hard drive connector? This is an old hard drive, so it's a parallel-ATA drive, not a SATA laptop drive. -- Matthew
