Another good option is a Raspberry Pi running OctoPrint. I had a couple failed prints after I got up and running last week. Since going to the OctoPi, my printer's been working fine. I'm running with the LCD panel unhooked right now.Shizuma wrote:Yeah, fortunately, and hopefully the new one they send will have the static discharge patch installed, honestly I'm surprised mine didn't since it was shipped after the news post about the problem with the board and that they had a fix for it.
Well with all the problems I've been having with printing via the SD card I'm not entirely sold on it, the new board may happen to fix those problems I've been having too, but honestly I think I'm just going to stick to USB printing, I have and old UMPC that I don't use anymore since I've replaced it with a tablet, however I think it would be a perfect computer to load repetier-host onto and make a permanent mount for it on my Rostock since it's a self contained windows 7 pc, and it's small enough that I could mount it directly to the rostock.
I do have some ferrites on order for my ribbon cables, and I'm going to try a few other bits to reduce the likelihood of noise.
If you wanted to turn your noise reduction efforts up to 11, you could re-cable all of your steppers in shielded cable (Cat6, take a pair to each of your 4 wires). Cat 6 is supposed to be 2x 24AWG per pair. 24AWG is rated at 3.5 Amps in chassis wiring, so you'd be OK with steppers that pull something like 2A max.
That actually wouldn't be a bad idea for the end stop wires either - split out a Cat6 up over the printer to give you 3 pairs (plus spare) for the end stops. Then, you've only got one wire to run down to the enclosure, versus fishing those fine-gauge wires through the extrusion. The Cat6 I bought has a little + shaped plastic piece holding each pair separately, plus a foil shield around the outside under the insulation.
