QuoteMy guess is this would require a version of repetier with integrated web interface like the Duet which may be outside the repetier plan... Yes exactly. In ARM there are Cortex-A and Cortex-M Processors. The processors on RasPi and boards like it are Cortex-A (A for Application). And you probably know that they are less powerful than your usual PC or Laptop. The Cortex-M processors like tby JustAnotherOne - Controllers
I do safety critical software to pay the bills. 3d printing is just my hobby. If you want to know the cost then you have to differ between hardware and software: On the hardware side (I'm a software developer, so this might be inaccurate) you need to know the safety specification and have to build in stuff to avoid all the dangers. On the mechanical side look at the Ultimaker+ vs the Ultimakerby JustAnotherOne - Developers
@MechaBits IANAL but I think you are over generalizing. If you burn down your house the Fire Department will search for the reason. The police and your insurance will be interested in the cause. If someone else started a fire in your house that is a job for the police. If you just fell asleep in the wrong moment. Or something else happened that you did not cause directly.

For Europe you will need CE. If you import to the EU without CE you may not get the printers over the border. But only if they check it. So you might get lucky. If you sell in the EU without CE then that might work. Most people don't know or don't care. So it is not impossible to do it. The question is what happens if someone burns down his house because your printer over heated. In that case tby JustAnotherOne - Developers

@ambrop7: You are right that the Chip can use Step+Dir signals. But it needs to be configured using SPI. It will not work without being configured first. The SPI Signal can also give feedback signals during printing. It also has a mode where it triggers on each Slope on the Step signal. So instead of Step pulses the firmware can just invert the signal to make the next step. @WZ9V: You can eitherby JustAnotherOne - Controllers
Hey ambrop7, The more software that runs on the board the better! The 405 and 407 share the same data sheet. Supporting it should be just a matter of configuration. I did not find the place where I could do that in your firmware. The Pin Out should be clear from the schematic. Does your firmware support the Trinamic TMC262 chips? I thought there should be something for them here. I would likeby JustAnotherOne - Controllers

The prototype boards have been rather expensive. A big part of the reason for that is the low number of fabricated boards. Producing 100 or 1000 would bring a dramatic price drop. And then this board is not deigned to be cheap. It should be the best, not the cheapest. On this board there are also some things that are sort of a test. If the test show that the expensive components are not needed thby JustAnotherOne - Controllers

@Dust: You are right a shield would be needed. For development one could start with any shield und just connect it with jumper cables. Even a normal board would work. just desolder the AVR or cut the traces. The much bigger issue here is the FPGA programming. I would start with only doing the Step and Dir signal generation in the FPGA and using a stepper driver chip. Changing to h-bridge only sby JustAnotherOne - Developers

The problem with the filament sticking out is not only the electrical isolation. With the two plate approach you would solve that. But the problem also is that the filament would trigger (in the two plate approach) a bit "higher". The two plates would not been pressed together when the nozzle hits them but when the filament hits them. The Filament that sticks out of the nozzle might be much moreby JustAnotherOne - Developers

@paucus I don't know if I understand what you are saying. Rotating the complete printer would only change the direction of gravity. And the printers you observed that print sideways or upside down only show that gravity has not much influence.
