Re: Bed won't heat...

As soon as my z endstop triggers, the firmware resets. The Z endstop cable is plugged backwards into the RAMBo socket. The RAMBo socket has three pins: [+ - S]. The two-wire switch cable ends in a three pin connector shell (*) with one empty contact. Unfortunately, the cable connector is not symmet...

Re: Bed won't heat...

Measuring the voltage across the bed power pins, I get 12v With a 12 V heater, the most likely problem is at the power input connector on the RAMBo board. The wires from the 12 V power brick generally work loose inside their screw terminals, whereupon the absurdly high current heats up the weak joi...

Re: No Need To Slic3r, Native .g and .gcode Files

3D CAD software out there that natively creates .g or .gcode files It's not just a 3D printing thing. CAD (computer-aided design) software produces a solid model, which a CAM (computer-aided manufacturing) program then converts into the specific dialect(s) of G-Code required by whatever machine too...

Re: M2 E Max Temp Err

throwing an error message of "Max Temp" Order a new extruder thermistor, install it, recalibrate the initial Z offset, and you're done. Search the forums for +max +temp (the + signs require the word to appear, as quoted strings don't work the way I expect) and you'll find plenty of discussions, wit...

Re: Can anyone recommend a 3rd party pinion replacement?

a pinion made out of the same material. Which would disintegrate almost immediately, because it gets far more wear than the planetary gears around it: https://softsolder.com/2014/07/31/makergear-m2-filament-drive-motor-status-check/ https://softsolder.files.wordpress.com/2014/07/img_4932-m2-extrude...

Re: Help! Printer will not fully power on!

I attempted to solder them back on tonight. If you soldered the connections backwards, then the fan will appear as something like a short circuit to its power supply. The fan on the motherboard will not start up. This suggests the M2 has a 24 V power supply with a pair of 12 V fans connected in ser...

Re: What have I fried?

Testing indicates the Rambo is not sending a signal to motor The board has two extruder drivers, so you can (probably) use the (presumably) undamaged driver. This requires tweaking the Marlin firmware source code to use the other driver, recompiling it, then reloading the Arduino, but it's been don...

Re: LED Lighting with RF remote control

how the heck does one physically get to it? Unscrew the terminals holding the wires from the power supply, tuck the LED wires in there beside them, then tighten the screws. If you install a suitable jack + plug on your LED cable at the M2, you can unplug the LEDs when you unplug the power supply, r...
