Please follow the commisisoning instructions at https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer?revisionid=HEAD#Section_Commissioning and let us know at which step it fails and what happens.
I have never had any problems with the E3D pushfit collets. Whereas I have had one of the metal teeth of a screw-in pushfit fitting break off and wreck the hot end.
Perhaps the OD of your Bowden tube is under-sized? You might want to buy some new collects and some Capricorn tubing from E3D.
Thanks - the F100 fixes the visible flickering, the probe still shows false triggering when the bed temp is stable so it hides, but doesn't fix the actual source of noise. My voltage with everything on is 12.8V but it drops to 12.4 with everything on and printing. All wire sizes are more than adequate for the loads and there are no loose or bad connections. It seems to me that maybe the corrections sent the bed heater are far more frequent than actually needed? On my bed it takes 14 seconds to drop 1 degree. I don't know how often it checks though when at target temperature. It is only when at target temperature when the problem appears and only on the bed heater. I have a much better 12/24V 60A regulated power supply at work which I'll substitute and see what happens, but I suspect it's a hardware problem with insufficient filtering somewhere on the power supply, Duet Wifi board or the smart effector. I'll get it on the oscilloscope during the week and see if I can find where it's from.
@dc42 Wow! That's messed up. I would never have guessed nor figured that out. Makes sense and sure enough I had like poles at the top of the smart effector right near each other. Switched it around and poof it works. Thanks for the help!
im using 1.21 on all the things. not sure about the rssi. ill check when I take the machine back to school next Wednesday
I do know we have 3 duet wifi and we all have the same problem some times it connects and disconnects after a few seconds and some times it will stay on for a hour before disconnects. one guy brought in a router for his machine and he seemed to be fine with it staying connected.
The digikey are perfect, the cable quality itself is really nice for the fast/constant movements of the delta effector so I'm really loving it, looks nice too. I just had way too much issue crimping the cat6 double wire and getting it to fit even though I have a good crimper. I've never really had that problem before. Also the cable fits a lot better(clips in and out with no pressure)
What is your dive speed set to?
I had issues with the configuration tool generating gcode where the dive speed was too low, instead of probing normally it would just slowly lower the nozzle into the bed without triggering the smart effector.
Once I corrected the gcode to the one found on the wiki it calibrated properly.
The driver I'm using has a PWM input pin, but when I tested it on the printer I just PWM'd the power input to the driver. It would probably be better to use the PWM pin.
Of course, they don't provide any specs on the PWM input pin level. I would assume it is a 5V logic level input since there's some 5V parts and a regulator on the board. Maybe compatible with 3V?
I don't like the behaviour of FB too, but on the other hand, I would not have so many customers without FB.
The thing with non profit discussion groups is, that commercial interests are often not tolerated there.
And you have a business too, David, and without us FB nerds, who shamelessly promote and advertise YOUR (and other good) products too in our several groups, you would sell a lot less Duets. Alone your german dealer sold dozens of Duet Wifi alone in the last few weeks by recommendation in our german FB group. Like it or not, that is a fact too, no matter that Zuckerberg makes profit with our data. Thats because the majority of people (and our customers) uses FB the most and they prefer it over other communication platforms.
Whatever you personally think of FB, it still helps keeping YOUR business going too. And that goes for many small companies / start ups, who would sell a lot less without FB.
I am in my sixties (old fashined too) and still prefer other ways of communication, but I have to live with the things, that a bunch of other people use on a day to day base, if I want to keep my business going...
M105 Szzz:aaa:bbb simply sends zzz:aaa:bbb to the effector. The reason for both aaa and bbb is that the protocol used to send the programming data relies on software bit rate timing without the benefit of a crystal at the Smart Effector end. So the microcontroller on the effector checks that bbb is the binary inverse of aaa before accepting the command, to guard against errors.
@3mm said in Smart Effector: How Many Temp Wires?:
Oops, I missed a portion of your reply, re; the 2pin replacement of the 4pin connector. Why didn't they just mount a 4pin?
Because E3D supplies their thermistors and PT100 sensors with 2-pin connectors. We didn't think users would appreciate having to remove it and crimp a 4-pin one on instead.
