E3D SuperVolcano on SmartEffector?



  • I am planning getting myself a smart effector as well as a E3D super volcano 24V hotend. Is there anything I should consider compared to a regular V6?

    @nxt-1 Supervolcano uses an 80W heater cartridge and it looks like e3d supply an external MOSFET if you select 12V due to the current draw (80/12 = 6.66A) so you are absolutely right to plan to run your supervolcano at 24V (3.33A)! That will work fine with the smart effector from a current draw perspective (use cables for the heater suitable for 4A+ to derate a bit.

    The supervolcano screws into a standard heatbreak AFAIK so that should screw into the screw top V6 heatbreak we provide with the smart effector.



  • @T3P3Tony Good to know the smart effector can handle the current. Thanks for the confirmation.

    I hope the added weight won't cause any issues either.

    @nxt-1 Its hard to know until you try it, not sure if anyone has done so yet. The smart effector can have it sensitivity changed by the duet if you need to, also you can change the speed of the probing move. It does not matter if the probe triggers when its not doing a probing move (actually it quite possibly will trigger when not doing a probing move with the extra mass a long way away from the smart effector!)

    What i would be more concerned about will be any slight quality issues you have with the mechanical design being amplified by having the nozzle quite a lot further away from the plane of the smart effector. some will be sorted by the autocalibration but not necessarily all. On the other hand the supervolcano is all about printing with large nozzles and fat tracks so they may not be noticeable,

    Keep an eye on the traces joining the heater connector with the 6-pin connector. The copper on the Smart Effector is thinner than usual in order to get a high enough resistance for the strain gauge traces, so it doesn't carry high currents well. We heard of the heater traces failing on two effectors. In response, we made the traces wider and duplicated them on both sides when we revised the design. I hope this will be sufficient to handle the 4A+ current draw of a 24V 80W heater. The traces can be bypassed using wires if necessary.

    Should I be worried? I don't mind doing it as a first but I don't really want to end up with a broken effector 🙂

    If your Smart Effector PCB revision is 1.3 then you should definitely add wires between the connectors to bypass the traces. If it's revision 2.0 then it may well be OK without, but add the wires if you wish. The worst that should happen if you don't is that one of the traces will fuse, at which point you can bypass them with wires.

    If you do add wires then they will need to go over the edge of the effector in order to get from one side to the other. So make sure they are protected in case that edge can bump into anything.



  • @dc42 I am planning on ordering from E3D in the comming weeks, I will ask them what version they are sending out.



  • I know I am digging up an old thread here but I wanted to let anyone that happens to stroll by know that I have successfully printed with the Supervolcano + Smarteffector combo.

    I did have to reduce probing speed and increase wait time after each move. The values in here are most likely to conservative, but they do the job for me: M558 P8 F800 H7 R1 T10000 A10 S0.04

    I plan to do a large-ish job this evening -6hr printing and I will report back when I have time with the results.

    Thanks for the feedback!

    I lowered the waiting parameter R to something like 0.5s and that seems to work fine. I also had to lower my acceleration/jerk parameters to account for the increased mass of the effector and longer moment arm under the effector.

    I completed the 6hr print without major issues and also did a 28hr (2kg) print this weekend without SmartEffector problems. It would have been interesting but I did not perform any measurements and even just feel the temperature of the relevant heater traces on the effector.
