I tried sending the M906 code from the terminal, but all that happened was that it generated a blank "print log". Do I have to do that while trying to print something? I peered at the board that's stuck underneath the platform of the Rostock. Is there an easy way to get access to it to mak...

Okay, I'll do that and report back. In the meantime, I was looking at the Prometheus system you recommended. https://www.distechautomation.com/products/prometheus-system Did you get the multi-filament kit, or just the hotend? It has this note: "The Prometheus System is compatible with 3D printe...

It does seem like some kind of EMI issue; that sounds like a good plan, thanks. Is it proximity to the board the main thing that needs to be avoided, or proximity of the heater wires to the stepper wires, or having the wires cross? Would slipping a grounded braided shield over one or another wire se...

This printer has a lot of problems, but I'd like to get it working. How does one change the motor current? And which hot end is the most reliable? Mine has stopped spitting out plastic reliably; I think the filament must be getting hung up somehow, although it may have to do with the feed mechanism....

So aside from calling Roto-rooter, what should I do to stop this from happening?

By tightening the belts and loosening the wheels I seem to have managed to drive away the demons that were causing my Rostock Max V2 to go into convulsions at the outset of each printing session. But after one successful print, I started another, only to find that it was printing happily away but no...

Your rapid speed might be too high (more than about 225mm/sec) and that'll cause the motors to skip steps. [I was starting to suspect that as well, so I slowed it down to 85%. That (or increasing the preload on the carriages) seemed to help; at least I was able to print 50% of the Stand without hav...

Everything that happens after it "suddenly freaks out" is because the effector is no longer where the electronics think it is. Deltas do goofy things when they don't know where in the build volume they are. [How do the electronics keep track of the hot-end's position? I thought this was a...

Hmmm, can't say that I've had that problem before. I'm inclined to agree with the techs about the belt tension. It looks like the hotend got caught on the print (maybe the hotbed), causing the belt to slip on one of the axis, which threw off the rest of the movements. It shouldn't be that difficult...

I got this Rostok Max2 recently, and at first it was printing pretty well. Then in the middle of a long print it shifted over and ruined the part. Since then it's been all downhill - while it seems able to print small things like the sample coin and calibration cube, on anything larger, like the sta...
