MiltyKoss unit 1 is alive! I still need to get some stuff taken care of to calibrate, some decisions to make. Hoping you all can help!
Questions:
Printer needs a 12v heat bed, recommendations?
I am running this without any LCD on a Duet 0.8.5, thoughts on that? Issues I might have with no LCD? I have a touch screen tablet with full USB and networking that runs windows 7 that I plan on using as a dedicated printer server, so I can use that for the web interface (Fujitsu T901, older but pretty nice for this function).
I am confused by the inductive sensor and the Duet, can anyone confirm wiring color code on a LJ12A3-4-Z/BX? I am using the E0 endstop per DC42’s comments on the RepRap forum.
Are the plastic jumper connectors usually used for breadboards OK for dc 12v fan under .6a? They are well crimped, but worried about heat long term.
Thanks y’all, great community here I appreciate all the help getting this far on this build.
Fans should be fine with practically anything, they’re typically <0.1A unless you’re running something huge. Do make sure your hot end fan wiring is secure, though…
@Ryan_Carlyle I sure will, it’s going to get a heat shrink tube over the effector side fan connectors when I hook up the heater core (I have it unconnected for calibration and testing other than extruder testing).
The pins on the Duet board are sort of wide profiles, the headers will not come off without quite a bit of force, uncomfortable amounts to be honest, but the upside to that is they are not disconnecting from any vibration.
For the heater core leads I used a terminal block. Bent the pins from the terminal into closed loops and passed stranded wire through and around itself twisted and locked, then soldered, then double layers of heat shrink tube, both leads individually and then together.
Temp sensor still needs attention to the connection junction, likely just heat shrink that as well.
Hey moderators, I am getting all this spam on this post from some iranian website and a obviously hacked account, can you block that?
Ugh, so my inductive proximity sensor LJ12A3-4-Z/BX does not sense anything but high grade steel. It detects a steel plate, but will not detect the aluminum build plate or a sheet of copper I have on hand to test it with. Any advice? It is connected to the 12v mains (per dc42’s advice on RR forum) so it should have enough voltage to work to specifications. its connected to the E0 endstop header and it is working with steel plate, it just doesn’t seem to detect anything else. LED brightens for steel at 4mm distance, does nothing for aluminum or copper that are in contact with the sensors head.
I already ordered an IR unit, after reading all morning about the issues with the accuracy and wiring of various inductive sensors. I would rather auto calibrate and level to the actual surface printed on anyway, but I would like to get this inductive sensor working if possible until the IR unit arrives.
You might try a new post asking just about the inductive sensor, most people won’t see a comment after the initial post rolls down the feed a ways. (I don’t have any idea myself.)
