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...

Re: LED Lighting with RF remote control

one of the pairs of connectors (A, B or C) on the Power Input block That's the ticket: the board gets 24 V at each pair, so any pair will provide 24 V to your LEDs. Earlier M2s used 12 V for the platform power supply and 19 V for everything else. Separating the supplies allow you to use different v...

Re: Layer shifts sometimes

the diameter varies quite a bit Typical filament can vary by 0.05 mm either way from the nominal 1.75 mm, so it's within spec. However, the diameter should vary slowly along the length; if it's ripply enough to see and measure that easily, I'd call it junk. maybe the stepper needs to drive harder t...

Re: What have I fried?

a blown fuse or have I fried the electronics board or something else? The schematics don't match the quick-and-easy documentation, neither of which may match your board, so check all the fuses. The schematic shows the red fan wire connects directly to the +24 V supply through fuse F3, the little on...

Re: Layer shifts sometimes

a wide base and thin walls The corners of the walls warp upward, the nozzle smacks into the bulges, the XY stepper motors stall, and the next layer is offset. A few layers later, another bulge, another whack, a different displacement. It's essentially random, although specific model features tend t...

Re: T-Glase filament and changing out nozzels

a mold I will use to pour beeswax into 3D printed objects have porous surfaces, which means molten beeswax will penetrate the surface. When the wax cools and hardens, the object will bond firmly to the mold and, because the mold isn't flexible, you won't be able to pry the object out. Lubrication w...

Re: Extruder calibration and fill problem

the constant pressure for hard firmament is not going to be good for soft A constant idler-to-gear distance produces an equal indentation for a given diameter of any filament, but it can't compensate for expected variations around that. With a spring-loaded idler, you must figure out what pressure ...
