Re: SD-Card slot corrupt?!

The SD card slot on the RAMBO only supports the I2C interface not the more common parallel interface. Not all modern SD cards support I2C so they simply fail on the RAMBO, typically smaller capacity cards are more likely to work, but there is no way to tell by looking at a card if it will work.

Re: Yet another Duet-to-HE280 accelerometer probe adapter

There's a bit of "hidden circuit" here, since for I2C to work the GND supplied to the HE280 must be the same GND that's on the endstop connector. And, of course, the HE280 still needs power as well. Important info for anyone with a hybrid hotend, using the HE280 solely for the probing feat...

Re: Help with i2c send error, accelerometer

I know you think you have everything wired correctly, but odds are this is a wiring issue of some kind. Do you have your E3dV6 heater and thermistor wired via the HE280, or is the HE280 wired independently? Pictures may be easier than words. For I2C to function, you need 12V Constant, GND Constant, ...

Re: Rough print

In Repetier M205 is the gcode used to dump eeprom settings. M206 is used to set an eeprom setting. Documentation here: https://github.com/repetier/Repetier-Ho ... M-settings

Previous versions of Repetier used to support M503 as an alias for M205, but that's gone now.

Re: No DC Voltage to printer bed

The same power supply provides power for the Rambo, so I find it hard to believe you aren't seeing 12V at the power supply. To test 12V power at the power supply, put the red lead of your voltmeter on one of the +V screws, and the black lead of your voltmeter on one of the -V screws. Check the blade...

Ungrounded is a scary word primarily when you're talking about highly conductive enclosures that can shock you. Wood is a very poor conductor.

Re: EE question: A DPST switch, a neon lamp, and a resistor walk into a bar...

You can simplify the wiring if you use an IEC inlet with the illuminated switch and the fuse built in, e.g. m. Not much simpler on the wiring, as it only eliminates one wire going to the fuse. The switch is electrically independant and still has to be wired correctly. However, it does mean there is...

I can visually see that pin 2 in that last image is ground. Note that it's connected to pin 2 in the endstop connectors, which are also ground. You can confirm this with a meter...you should get a 0Ω reading between that pin and any known ground pin. Ditto for pin 1 and any known VCC pin. Whereas pi...

Re: Heatbed solder pad came off!!

You can connect one or both thermistor wires directly to the thermistor leads instead, which is all those bed pads/traces were doing for you. Just make sure you do a good tape job when you're done, so that there are no mechanical forces applied to the thermistor leads. They're really fragile. If the...

People rarely mention what their ambient temperature is in the printer room. The colder the air flowing above and below the bed, the more the heater has to fight the environment.

Re: No M503 or M304?

Looks like in the prior versions of Repetier M503 worked as an alternate way to invoke M205. This alias seems to be gone now. Solution: use M205.

M304 was never there -- that only exists in Marlin-derived firmwares, so far as I know. As you suggested, M206 will work.

Re: Fixing the controller (RepRapDiscount)

Does the machine behave via computer control on the USB interface? No resetting?
If not, disconnect the reprap cables and try again. If it still misbehaves, your issue has nothing to do with the reprap controller.
If it behaved, then try just the LCD cable connected to see what happens.
