Smart Effector issue
-
@tecno "can not reach all the points" seems to be a different complaint from probe sensitivity. Is that now the problem you are now trying to resolve? If it is the location of the points, what matters is your M557 - what M557 command do you have?

Not one word what can be in that file to be found!
Im afraid that is not true.
There 100% IS an example of what can be in a mesh.g file, it is shown in the docs which can be found HERE
If you scroll down to the G29 command it lists what each "switch" for the command does and it also shows an example of what said mesh.g file can contain.
OK
Then I have to excuse me not understanding English that well.
Anywho my problem still exist with can not reach

M557 R80 S15Have you carried out a step by set system setup and auto calibration ? it seems like your M665 command is missing switches. The M665 command in My delta looks like this :
M665 R181.428 L490 B135 H300.182 X0.093 Y0.252 Z.000I have a smart effector too. i might be wrong as its been a while since i set mine up but I think what i did was reduced the radius and spacing in the M557 command until it actually worked and I then incrementally went upwards until it failed

Your mesh grid is right to the limits of the bed. I'd try M557 set inwards slightly - say
M557 R75 S15.If that doesn't work, how does it fail to reach a point? What fails? Does it not move far enough? Does it generate an error? Does it generate horrible grinding noises and a smell of burning? What actually happens when it cannot reach?
Also, can it reach teh point it seems to be failing if you just put those coordinates in a
G1? -
@tecno said in Smart Effector issue:
The rods and the adapter are original Dreammaker OverLord PRO, going back to a larger/wider effector (original adapter) made the situation better. Only trying to get this old Delta printer functional with a bit more modern parts.
I am in a process of building a large Delta of 1.4m height and ~550mm print diameter, Rods 610mm long directly to Smart Effector via magnets.This is extremely interesting as I'm still using my Overlord Pro, with the Dream maker hot end upgrade (V6 style) from some years ago.
The arm joints are getting tired and I have been considering fitting a spare Smart effector - but I'm still looking for appropriate arms etc., as the old ball joints are wear-prone and it seems daft to use new high accuracy parts with those.My larger machine has a smart effector on mag arms, which works superbly, the trigger distance near enough zero and amazing repeatability!
Back on topic:
If you want to retain the Overlord rods, I'd suggest using the Overlord effector plate and opening out the centre if required, so the Smart Effector fits through and is only attached at its original magball mounting holes.But, rather than screwing the two directly together, use long screws or threaded rod and commercial heavy wall tubular spacers or very precise printed blocks (for accuracy and rigidity) to offset the smart effector PCB upwards, so the nozzle offset below the plate is similar to the original overlord hot end.
It looks like spacers around 28 - 30mm long would be appropriate.
That will massively reduce the nozzle to effector leverage and tilt forces and increase accuracy, compared to having the entire hot end below the Overlord effector plate, with the rather flimsy arm joints.
(To reduce rod joint backlash on mine, I have a fairly strong rubber band around the centre of each pair of arms).

Hi Robert,
This is my temporary setup with the original effector plate.
My studs are 15mm and I have been thinking about adding 15mm to mimic original head setup.
So I will do this now and see what it gives. -

@tecno
The motor noise and "buzz" is very strong, it may be causing enough vibration to shake the smart effector?What Duet board are you using, and how are the motors configured?
(My Overlord is extremely noisy, but still using the original control board; the larger Duet controlled machine next to it is totally silent! )

Yes it is, resonance box of worst kind as all parts are loose it sounds like.

https://youtu.be/UrhxmyiwaEEAre they intended to be answers to the questions you've been asked? From what I see, the effector reached all positions it would be expected to reach. It's false triggering before it hits the bed, but that's not what I'd call "can not reach all the points".
Does that video show the behaviour you are trying to correct and that you have described as "can not reach all the points", or is this supposed to be illustrating something else?

The whole story started with false trig's and after a lot of tests it kinda worked OK then these can not reach started, now the points are reached and false trig pops up. This is a sensitivity issue as so many parameters can get to make issues like dive height I had yesterday. This is a bloody mess so I start to think there can be a problem with the board it self.

OK, sorry I don't know that board. Presumably its running Reprap Firmware of some version, if the config is compatible with Duet boards??
The false triggers seem to only occur during movement, not when the machine is stationary? If so, it can only be either mechanical resonances or a wiring problem with crosstalk from a power cable to the sensor cable.
As an experiment, you could try putting some sponge rubber or wadded tissue between the sides of the heatsink and effector frame, to damp vibration without restricting the end movement on the smart effector too much, and see if that reduces or eliminates the false triggers?
If it does, the solution appears to be to try and improve the stepper driver settings or type, so they don't rattle the whole frame??
-
False trig occurs when there is NO movement, can make longer delay with M672 still false trig.

Sorry, I'm not familiar with James. Is that from a Duet reseller?

@phaedrux it's bought directly from Duet3D in the uk

@tecno Please send an email to warranty@duet3d.com. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out. It's possible there is a sensitivity issue with the Smart effector, swapping it will rule that out.
