tevo little monster duet wifi



  • hey all. im waiting on my tlm to show up. i got a duet, smart effector, 24v berdair, 400mm hyden arms, noctua 40mm 12v pwm fan, and a zesty nimble with a nema 14 (still waiting on it to be delivered).

    i am having a bit of a problem trying to figure out how to wire it all up. i have read the other how to guide. but they used the stock effector for the tlm. i have read the guides for the duet and effector. and am a little confused how to get the 12v fan and 24v berdair pump to work together. i would like to work the pump direct form the board. i have a flyback diode for the pump. i also have a 12v pump if that would make things work better. i was considering using one of my buck converters on the always on fan headder to get the 12v but i dont know how to get the pwm signle in the 12v range. the ground on the converter is a pass though between the input and out put.

    also dose any one know how long the cord from the effector to the plugs should be?

    thanks

    Unfortunately I can't see your pictures, I think you must have them in a private location.

    You can connect your 12V buck converter to the always on fan header, then connect the red wire of the 12V fan to the output of the buck converter, and the black fan wire to the FAN-pin of your chosen controlled fan output.

    Version 1.02 and later Duets have flyback diodes included in the fan output circuits, however adding an external one does no harm as long as it is connected the right way round.

    You can upload pictures to this forum using the " upload Image" option, just make sure they are <2Mb.



  • interesting you cant see the pics. they are links from my google photos. they are just of the smart effector with hayden rods and the duet bord.

    dose the wifi server version look correct to you?

    ok so let me see if i got the fan thing correct.

    i have a 24v power supply and a 24v berdair pump. i hook the positive and groun up to one of the pwm headers on the bord
    the 12v 40mm noctua i use a buck converter and get 24v power form one of the always on fan header, then down grade to 12 v and send just the the positive to the fan. then i hook the pwm and ground to a pwm header. do i hook the ground to ground and the pwm to positive?



  • also for whiring i was wondering if you though using some cat6 eathernet cable would be ok for hookup on the thermsistor, fan power, and the probe? i also have some 2 pin wire 18ga copper clad aluminum i was going to use for the hotend heater power. it says its rated for 24v

    No, it should be 1.21.

    If your 12V fan has a separate PWM control input, connect the fan + and - wires to the output of the buck converter, and connect the PWM wire to the FAN- pin of your chosen controlled fan output. Use parameter I1 in your initial M106 command to set up that fan output.



  • Finally received my tlm. And tasted to put it together

    I'd upload a pic but I don't know how to resize it on my phone

  • ok im having some problems. i got the bord all wired up and it homes and dose the bed probe just fine. i used the reprap firmware setup tool to config the config.g im not sure i got the radius and such right though. all i know for sure is my arms are 400.21 and my printer radius is about 180mm not sure what the smart effector radius is. i think its about 3.5mm? i have the berdair pump set up on one of the pwm headers but it wont turn. it blips twice during start up. i use m106 to try to turn it on but nothing.
    i tell the heat bed to go to 60 but i get no voltage out of the bed terminals. and the hot end dosent even try to turn on. im guessing its because i dont have a fan wired up for that yet. i think im going to have that as a always on fan

    here is my config.g
    0_1526517295903_config.g



  • With regard to the various dimensions being right: Get the L parameter of the M665 correct (400.21), and then run a G32 to set everything else.

    Be sure and save the G32 with an M500, and be sure your config.g contains an M501 to load the settings, somewhere near the end of config.g



  • I did have that parameter set correct. But it only probed a 210mm dai area of my 310mm bed. It said it was 10.something out before and 2.something out after.

    That's OK for now.

    To fix that later, edit the bed.g file, and/or generate another one with the online configuration tool. The coordinates in that file determine where the probes occur.

    Here is mine. I have a 604mm dia bed. So you could probably just half all of mine for a 300mm bed. Might be simpler in some ways that going all the way through the configurator for just one file.

    But you can also run DC42's Bed.G file generator



  • Thank you for the help. Now to figure out why it won't heat up
