@ignacmc said in Smarteffector Z Probe trigger height:

Successful G32 calibration and then I set Trigger Height (-0.212 this time)

Why do you change the trigger height after auto calibration? The trigger height should be fixed assuming that you don't change the sensitivity or the probing speed. Measure it, set it in config.g, and leave it alone.

Changing the trigger height setting between auto calibration and mesh probing will give you a height offset.

@dc42 said in New version of the Smart Effector?:

@uk25 we have a newer version in development.

Will that have the lis3dh integrated and possibly utilised as the Z Probe? And maybe CAN Connectivity?

No, it's not a combined Tool Board/Smart Effector, although that is on our list to do.

Yes - I can confirm that by “set correctly” I mean that there is no jumper.

I’ll have a look and see what I can figure out, but to be honest, I’m a bit dirty that I only just got this printer built, working and dialled in, and now I have to pull it apart again just as I got to the fun bit. 😞

That said, I’m happy with the Smart Effector, except for this failure. I think it has become an essential component in any decent Delta build.

@pcr
Actually the design is based on the Sherpa Mini 👅
But they all use BMG gears (with Orbiter motor), but without planetary gears from the Orbiter.
And they seem to require a wider rod-spacing or higher adapter to clear the rods.

Here is a teaser of my ongoing experiement, trying to free some space between the rods.
It's too early so say anything.

@bassco How did you configure the Smart Effector for Klipper?
I can't seem to find any info on it 😞

This is my current config:

[probe] pin: PC1 z_offset: -0.1

The wiring was okay and was in working order before going Klipper, so that's not a problem.

@apak Thanks Guru!

@fcwilt Sorry - I mistyped. " and then run bed.g via G30." should be " and then run bed.g via G32."

@garyd9 said in Duet smart effector directive drive on E3d titan aero:

The only reason I recalibrate on power loss is because RRF (for some reason) can't use the M665/M666 settings to determine how to re-apply mesh compensation. (It's been explained to me at least once, but I never understood it.)

Can you link to a thread about that? I can't remember the reason either, and it might be good to fix it.

I can't quickly find any of the older threads, so I just created a new one here:

Thank you

@droftarts I think I got the probe working. Not really having any better ideas, I inverted both the z probe in pin and the z mod pin in the cogfig.g. When that didn’t work, I inverted just one pin at a time. Apparently having the mod pin inverted did the trick, and it works, although I have absolutely no idea why that is the case.

I also plugged in a spare thermistor directly into the board and it worked fine, so I’ll do a little fault-finding. Perhaps it is a bad sensor...

@jay_s_uk I'll do, thanks

Have you put the arms on in such a way as to minimise the magnetic fields given of ie to have nth and south poles adjacent to each other round the effector?

Are the print cooling fans running? The magnetic fields from running fans can induce enough voltage in the effector electronics to trigger it.

@nurbie
I have the Smart Effector on my RMax v2 with the molded cheapskates. The carriage adapters that come with the SE will fit perfectly on the molded cheapskates where the ball joints mount. 713Maker has some really nice stuff, but learn from my mistake and don't get the SE to ballcup arm adapter ($40). The problem with the 713Maker adapter is that it increases the distance of the arm articulation points between axis (not between the two arms of each axis, but between each axis) which makes the effector VERY susceptible to tilting. This wiki page describes it all very well.
Just order a set of 304mm (or larger) magball arms to go with the smart effector and you'll appreciate the upgrade from stock.

Let me know if you have any questions

@ignacmc said in M12 Heatsink does not fit PCB Smart Effector Hole:

@ignacmc One last question...if I want to use a "non-threaded" heatsink like the Mosquito or Dragon Hotend....Will it work with a M12 printed adapter? there are some on Thingiverse

713maker do manufacture an adaptor for the Mosquito which IMHO would be the best option see https://713maker.com/gb/mosquito/mosquito-hot-end-duet-smart-effector-adaptor

@mrac1 could you share a step/F3z file of your double blower mod for the mosquito I definitely need to try that, it looks awesome, but I can't find it on your thingiverse page... 😞 I assume that you've got a 713maker mount too.

I thought it was in the D3E step file, but I can't find it in either.

@3mm
That's normal because DWC only polls data every n.n seconds. If the Z-probe really misses a probe, you get a warning or error in the console.

@garyd9, from the symptoms you describe I am fairly sure that your effector has the old firmware, and reprogramming with version 2.01 firmware would fix it.

@garyd9 Yeah I'm curious what's actually going on with the hex file being present in the sys folder would actually do.

Thanks for the reply, i measure the Molex Crimps outside of the connector before the Molex in and there were fine, i had no clue how to meassure inside the connector.

Well that solves it. When and where did you purchase the smart effector?

@polbofree I'd hope you gould get a bit better than that, but I don't have a smart effector so can't say for sure. I would say that such variations could also impact how accurate your delta calibration is so I would definitely look at improving it. A couple of things to think about/check:

Are you probing with a hot nozzle? When I used a nozzle contact piezo I always heated to 130deg C and did a double probe (i.e. two G30's). That was hot enough that any filament on the nozzle got squished after the first probe, but if I went much hotter, the nozzle would damage my bed surface (I use a Ziflex flex plate).

Have you gone through the smart effector comissioning wiki page (particularrly the section on settingb the sensitivity)? https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer#Section_Commissioning

Your M558 in config uses probe type P5, but I beleive P8 is recommended (it's the same but unfiltered for a faster response)

In general, nozzle contact probes require a stiff mechanism to get a reliable result. Any backlash/flex issues in your delta arms or carriages could be giving you issues (and could be a source of your dimensional errors?)

You can use the A & S parameters in your M558 definition in config to setup repeated probing to improve accuracy. I do this on all my printers, but would generally try and improve everything else first. Typically I use A10 S0.01 (so it keep probing until two results are within 0.01mm of each other and take the average of those two, but if it gets to 10 probes it just take the average of all 10)

Hope that helps!
