You are using a high quality cable connection that I can’t imagine that would be the problem when it’s new. The nimble’s drive cable will flex less than an arm will. I would think it would help. The only other suggestion would be to use silicone wiring but I don’t think that would help much over you’re pre assembled wire bundle.

@BigMoff96 said in smart effector 12v/24v jumper question:

@dc42 If my psu itself is 12V and my heat sink fan is 12V. Would My effector need the jumper in that case?

Yes. Without it, the illumination LEDs will be dim.

@Phaedrux I’ll try resetting the sensitivity and let you know how that goes. I switched the probe type to a P1 based off another forum post and it seems to not be staying high after probing. If I change it to a P5 or P8 it will reproduce the behavior I’m seeing.

Hi,

I cannot say anything on the smart-effector, BUT if you have a chamber you DEFINETLY need at least 1 fan + tempsensor that sucks out the hot air on top OUTSIDE of your chamber for the same reason (of course for that you need an inlet at the bottom or side at the bottom) above a certain temperature (for each filament diffrent, define it therfor in filament-config.g)!

Most things like the avarage-joe stepper-motor, pcb, mosfet, you name it will degrade in powers of ten for every +ten of more heat... so for having long fun with your electronics you should take care 🙂

E.G. get an additional thermistor from the duet-website/-reseller that you screw inside your chamber at the top where it is most hot and a 80-120mm fan (do not take the small ones take a big/long one with power because you can still drive it with PWM to use less of its power) and 1 cheap dustfilter for inlet, 1 good for outlet (that the air gets a bit cleaned when it gets in and even more cleaned when it gets back into your room)

In my case for duet2ethernet with RRF3.1.1 an example:

Than e.g. in your config.g put with M308 a new/higher S_ then what is you have already, in my case:

M308 S3 P"e1temp" Y"thermistor" T10000 B4274 C0.9018123000e-7 A"Chamber" ; configure sensor Sx as type"thermistor"/"..." on pin P"..." see https://duet3d.dozuki.com/Wiki/Connecting_thermistors_or_PT1000_temperature_sensors#Section_Thermistor_parameters

and define the fan later, and connect it to the sensor created before, in my case:

;chamber fan: M950 F2 C"fan2" T3 ;Q500 ;! ;Q25000 ; create F=fan(x) with "!" to invert, on pin C; opt set frequency(Q) e.g. for most real 4-wire pwm-fans 25000 (max 65535), ordinary 2-wire must be kept low around 100-500, default seems to be 250 ; set some default vals to start but override it in the print-file with the specific filament-config.g: M106 P2 C"chamber fan" B1.0 L0.9 T40:50 H3 ;X1.0 ; P=num; s=set speed 0-255/0.0-1.0; limit L min & X max; H=heater monitored+Thermostatic control, -1=off or Hx(:__...) monitored; B=blip time in ms; if not thermostatic (H-1) define a board-boot-start-up speed S=fan speed;

I am currently in the state of replacing my temp-sensor with a DHT because besides temperature I can track the humidity inside the print-chamber to get to know how it influences print-quality...

Hope something here is maybe of some use for you, just my experience here... 🙂 Good luck!

Phaedrux MODERATOR 29 May 2020, 22:52
When you send G28 to home it's calling homedelta which is moving all the carriages to the endstops. This is clearing your calibration

I should have said resetting your homed height established by G30, but in the context of that thread I think it made sense, though not applicable universally.

@bartolomeus said in Print surface for delta with smart effector:

8mm thick plates i

with that i think you need grooves milled in where you can place the magnets

@Adrian52 I used those back in the day, they work well. I printed them in PETG fearing PLA would load creep over time.

@Phaedrux

I learned a very long time ago that I dont need to worry or care about what anyone else thinks to be able to live

@weed2all

I will try this first, I also have a precision piezo that I might design a mount to go under the nimble, im a big fan of the zesty nimble.

Just wanted to see if this was "do-able" my next task is to get the smart effector to talk to the LC-1 Tool board !!! and see if I can use multiple duet IR sensor boards purely as end stops.

I can get the IR sensor to detect the heads of an Allen bolt so I dont see how it cant be made to work.

@dc42 That would make sense.

finally i mange to flash the smart effector with the hex file provided by dc42. but i am still having problem. the green light does not light up at all. also the probe function is not working.

what else can i check?

I suggest you use your multimeter to measure the resistance between H+ and D1 (should be 750 ohms), between the other side of D1 and D9 (0 ohms), between the other side of D9 and D7 (0 ohms), and between the other side of D7 and H- (0 ohms).

@Maniax, I'm sorry you have received a faulty Smart Effector. Are you experienced at soldering? If so then you have my permission to solder those pins yourself, and the warranty will not be affected.

@justus2342
I run G32 and G29 S1 to enable mesh levelling which is not always need if your bed is in good shape and level I dont run G29 everytime as it stores the heightmap

I run G29 if something has change ...nozzle, effector but only then
Yes you need to make sure the nozzle is clean as it cant account for plastic on the nozzle.
You can run G30 S-1 to do a single probe as a minimum for G29 S1 to be effective

Hope this helps

I can't see anything obvious on that smart effector. Since this particular smart effector is still within warranty and we can't see any obvious damage we will authorize a replacement. Please contact your seller and initiate a warranty exchange.

@CoolioX said in Smart effector flashes 7 times repeatedly.:

@Phaedrux -- I have recently purchased a few smart effectors and without fail I have 3 of these that are flashing 7 times. I do have one that does work, so I'm pretty sure it's not anything having to do with the external set ups, but it seems strange to me that a bunch of them would have the same issue?

For reference, where are the strain gauge traces?

Hi, please create a new thread with your issue for the sake of clarity.

@c310 said in shorted heater, track burned out:

self-resetting fuse

really depends on the type, some have a relatively high resistance which will lead to heat. look at the datasheet and P=I^2*R

Hey all I looked over my config and realized I'm an idiot. I was pulling specs off a site and they were way off. I lowered it and was able to get the probe to work properly and just need to wait until I'm off work to load some filament in and get started. thanks again guys!!
