Hi all. Well I got the Robo R1, (enclosed bottom) a week ago, took a few days to get to reading up and setting it up for a test but I got there. Right away I knew I wasnt going to like the soft much (I'm a Mac OS X user and while good software for sure its not stable enough for my tastes, not yet anyway) but just like when I got my Roland Plotter, use what the give, learn, then decide what you need and move on, anyway... So, I normally first make sure all software, drivers and firmware are updated but updating the firmware using MatterControl on a Mac seems to be an effort in futility. So we move on. I get it all set up, checked out and feel i'm ready to go and load up Business Card 2 from the library and give it a go, haha, funny stuff. No adhesion and print head way to high from bed. So, of the this forum and the internet in general. I then turned off auto leveling in the software and and it seemed to help, laid on the vinyl supplied and saw what proper adhesion looks like but was still having issues. Print head seemed to be destryong what it printed, or something. Anyway, left it for the night (I find giving my brain time to mull it over in the background helps) and started free next day. So I did some more reading and watched a few videos and found one of my level sensors was out of position (making it print like a drunk spider) and the heating cable was getting in the way of the bed position sensor, got that all sorted and clicked print and BOOM, got me a black business card and pen holder! nice. So, I looked around online and found this: http://www.thingiverse.com/thing:308335/#files and figured thats a killer first proper print to make so I got the files, loaded them in and got to it and to my enjoyment it printed the lower jaw very nicely indeed. So i figured I had it licked, hahaha. Next day I go to print the T Rex skull using Glow in the Dark Green (Robo purchased) and wow did I have issues. Started with filament not feeding, found a piece stuck in it, unscrewed the spring screws and after some fiddling got it out. then got a 10 guage High E string end out and made sure it was clear, loaded the filament and went for it again, no dice. This time the "gear" that feeds the filament was chewing through the filament instead of loading it!. more forums and it turns out they could be too tight. I mess around for 2 hours and give up, remove the glow in the dark green (Robo purchased) and switch to black as a way of eliminating the filament as the issue and it prints! So, I printed a black T rex Skull and Jaw and they look great, I'm very happy and very ready to try the glow in the dark again to finish what I started and learn some more, well it loads up and prints fine, like properly. So, My take on this is that filament must be a lot like T Shirt transfer sheets and that they are influenced by temp and humidity in the room they are used in. In all of this I read about seasoning the head and also installing an oiler, still looking into that stuff. So, here I sit with a very well behaved and properly printing Robo, nice. Life is good. Any thoughts, tips and what not? I own and operate a printing business and am very familure with wide format inkjet, laser and plotter/cutters as well, just for background and I use Mac OS X. Thomas.
