Wireless mod?

You can use Octoprint on a Raspberry Pi, pretty simple. I did a writeup here on the forums about it, as have others. I would say it is simpler than an SD card mod as it does not require firmware flashing.

Shameless plug - I sell all of the above, and would be happy to put together a package for $60 if folks are interested.

Octoprint.  Seems to work well as long as you are not using the camera...

Assuming the Pi still has Ethernet support, you can also connect directly to your router if its close enough. It doesn't have to be Wi-Fi. I would do this if at all possible, personally, because the area around my Wi-Fi network has hundreds of other networks competing for air space.

I have recently been working on this type of thing - a Raspberry Pi Wifi Print Server.  I installed Repetier-Server and it works very well.  I could control the printer from a network computer but it was also very cool to control it with my smartphone.  But it got a bit annoying that I couldn't control the printer occasionally when I was standing  at it.  I then found a great touch screen for the Pi.

The keyboard/trackpad in the pic below is optional - I only really used it for setup/config but you can do that from another computer too.

0 to octopi took ten minutes.  My problem now is getting it to play nice nice  with my printer.  If I let it slice with cura, and run a print, it prints at speeds I didn't know my workbench was capable of.  I have a couple of balls of filaghetti to prove it.  I cant seem to get my cura profile to behave like the repetier profile does.  I may end up with repetier server because of it.  From what I hear, cura seems great.  I might be trying to over complicate it, but I cant find any settings to get at least similar behavior to RH on my workbench.  Do any of you have any tips you can give me on the cura setup of octopi?

Thanks.

I tried that very late last night, but I think I octoprint used it's printer settings, like speed, instead of slic3rs.  Don't event get me started on the feed and flow rate sliders.  I'll have to go through it again.  It sucks that Solidoodle didn't deliver enough Workbenches for it to be popular.  It's an awesome printer, but it needed an SD card.  I see ramps in the future if this doesn't work.

Wardjr to the rescue...  I'll look.  Thanks!

There is in fact an sd card slot on the board, but after having read your rant on the Workbench, and having had many of the same issues, I'm wondering if I shouldn't just throw a RAMPS 1.4 I have laying around in it.  BTW, I had my x motor plug come out twice because of the control box placement issue.  The sd card would be great to have to eliminate the connectivity issue this thing seems to be plagued with, but if the firmware is so bloated that it runs out of memory to communicate that regularly, it hardly seems worth keeping it.  I'm just not sure if I should use the ramps or go for something newer.  I only want to do this once...
