      Part 2 of the guide is now up and goes through using the config tool to generate your first set of config files.

      Next guide will go through getting connected for the first time, updating firmware, and initial testing and commissioning.

      Good point, we need to measure them all again for 3.3.

      Quick update. I was checking out the board and there seems to be a bit of exposed copper plate. You will see it in the pic.

      @Reine Just found them on fermio.de, but IMHO they are quite expensive.
      IIRC I got 5 meters of NeoPixel RGB LEds for roughly the same price.
      Not 24V, but 5V supply, so what?

      @Phaedrux Okay, looks like the ribbon cable may have been "part" of the issue. I noticed that the tops of the connectors on the ribbon cables did not seem seated fully. I removed the ribbon cable, re-seated the top piece, and re-inserted the ribbon cable. I am now receiving 5v on the duex.

      The BL-Touch is still not working properly. It runs the self test on bootup and passes, stays lit red, but will not deploy/retract, or trigger. I'm using the default modix files, but I think it may be best if I start a new topic on this issue.

      @shirnschall After trying to get this to work for weeks, I found the error right after posting.

      I used the old RRF 2

      M106 F25000

      to set the pwm frequency when it has changed to

      M950 Q25000

      in RRF 3.
      The fans now work down to around 40% as expected.

      @sneakyferret

      There is no boilerplate answer to this question, it very much depends on things like wire gauge, the actual lengths involved etc. Are we talking a 1m or 5m tall machine?

      For the power wires you need to consider the voltage drop over the length of wire which depends on the resistance (and that also contributes to the wire heating). There are calculators online, and the thicker gauge the wire the less resistance - the longer it can be for a specific voltage drop. How much voltage drop is acceptable "depends", too much and your heater wont get to max temperature, or will heat slower. There are maximum recommended currents for specific wire diameters that are related to the self heating effect but you may want to be well below those due to the voltage drop.

      Also note that as the wires become thicker, then they become stiffer, and types suitable for continuous flexing like you will see in the connection from the top of the printer down to the effector become significantly more expensive.

      There are "data" wire on the smart effector - all the control wires run from the Duet to the SE, so the same considerations about the heater wires apply to the fan power, albeit that the current is lower to they don't need to be as thick.

      The temperature sensors are another issue, for two reasons. The increased resistance of the wires could impact the readings, especially if you are using two wire PT100. We have the provision on the Smart Effector and the PT100 daughter board to use 4 wire connections which removes the impact of the wire resistance on the temperature drop. The other issue is noise, with a long run you are more like to pick up noise, that said if you can run the temperature wire away from the stepper wires that will help.

      @dmandn said in Which wires to toolhead can be joined?:

      I believe the +3.3v and gnd pins for the x endstop and filament sensor can be grouped together? (laser sensor) (ie gnd + gnd, v_in and v_in).

      Yes.

      I believe instead of a GND, the +v_in for the fans can be grouped and the fanx_- is the control pin for the PWM fans? So that implies I should be able to group the V_fan connectors to one 24v source?

      Yes.

      BLtouch requires 5v for servo and 3.3v for probe in pin? possibly can share gnd with endstops for probe in?

      BLTouch does not need 3.3V. It can share ground with the endstops.

      Also, is the heater controlled on the + or -? Seems like they are also controlling the - side?

      Yes. You can common fan V+ and heater V+ if you take it from the heater connector, although you will lose the benefit of the lower rated fuse in the fan V+ supply.

      The thermistor wires cannot be commoned with other wires, except that 2 or more thermistors can share the VSSA wire.

      @gallaghersart @jay_s_uk is correct too much had changed (e.g many of the capacitors, diodes, the hole internal power supply circuitry etc) to make it make sense to convert.

      @jay_s_uk You are totally right, I was questioning my sanity but I tried the same with a different driver and it worked now. I guess that my driver was broken. There were also some software issues.Thanks everyone for your help!

      @kuon I think the difficulty will come in that the 6XD/HC boards have CAN termination resistors pre-soldered in place.
      You may end up having to go the route of 2 x 3HC's

      @Phaedrux I have previously tried all of those options. Dedicated 2.4ghz SSID, and multiple tails / multiple antennas (2-10 dBi) both directly connected or with extensions to locate the antenna in better air. Its not a physical issue.

      Its either a bad board or a firmware issue, and the solution to both is to move to wired. I didn't want it to be connected over wifi initially, as I intended to use it in SBC mode, so it wasn't an issue, and I had this wifi version spare. Still, now I intend not to use the SBC so replacing it with a wired version is the logical option.
