I also think that a Raspberry Pi based Simplify3D printer host would be great. I have a limited edition 5" AstroBox Touch from their Kickstarter campaign, I actually use it with my 7" Official RPi touchscreen and it works quite well. ( https://store.astroprint.com/collection ... 3d-printer
) But at a cost of $199 for a 3.5" AstroBox Touch (ABT) I would really prefer a Simplify3D host RPi.
goldengears5 was nice enough to make a tutorial to automatically, wirelessly, upload Gcode from Simplify3D when it is saved. ( https://www.thingiverse.com/thing:2612143
). While this is a nice step in the right direction, I would still prefer a Simplify3D, RPi based host.
When I first got my ABT, my Simplify3D Gcode exhibited some strange behavior when I updated to S3D 4.0. I initially thought this was a quirk with S3D 4.0. After adjusting all my S3D profiles I decided to try out a test print with Gcode from before 4.0 with my laptop and S3D as the host. It printed fine. I then tried the same thing but with Gcode from before I adjusted my profiles to eliminate the odd behavior, infill was not meeting up with my perimeters and I had adjusted my infill overlap to 80% just to get good prints. This unadjusted Gcode also printed fine when using S3D as my printer host, even after the 4.0 update. So I then printed Gcode with my adjusted profile and it showed over extrusion where the 80% infill overlap meet with the perimeters. This told me that my ABT was the cause of the infill not meeting up with the perimeters and not the S3D 4.0 update.
Since these problems and troubleshooting test, updates to my ABT have remedied this problem and I can again use my standard profiles for S3D without issue... just good old S3D prints everytime. While everything is going good now, I would still love to have a RPi based S3D host to control and wirelessly run my printer(s). Problems like those I described would be less common or frequent if S3D software was available from slicing, to gcode to hosting the printer... A to Z.
I love S3D, and would really love to see a hardware product with a low cost RPi to enable S3D to host printers. This could be a tangible product, or a software OS package, I would gladly pay for either one. Of course with all of the bells and whistles that S3D is already known for and loved for, it would only make sense to follow this same pattern and apply it to a RPi based host package. My ABT is great, I really do enjoy having a fully functional touchscreen host right at my printer, but I know that S3D could do better... just like you did with your slicing software.
