The connector looks like a Molex microfit 3 (?).

I use the Molex tool HT60923A aka 0011030043. It's easy to remove once you get the technique, inserting from the front on the right and left sides of the pin and on each side, rotate it a little back and forth to release the pin. It works for both male and female Microfit 3.

I use this setup from Thingiverse, with the E3D V6 hotend heatsink from the kit, titanium heat break, plated copper block & 0.4mm Olsson ruby nozzle.

That's with a Flex3drive system, so like this on top:

The end result is very light but as precise as a direct drive setup.

@adrian52 said in Orbiter 2 extruder mounting for Smart effector with Magball arms:

@fred-y Its 1.5mm.
You do need to be able to rotate your hot end - would be difficult with a v6 where the heater block really has to be aligned with the part cooling fan

It actually depends. The earlier versions that shipped with the metal nut had a fine pitch..

@t3p3tony Excellent, thank you so much for these detailed instructions!
I will try first on an old damaged Smart Effector v2 to make sure I can do it 🙂

@dc42
That's what I thought, too, so I reinstalled new crimps with no luck

@phaedrux will do.

@fred-y said in E3D Micro Revo with Duet2 and Smart Effector:

@jay_s_uk True but it just a little annoying to add extra wires/stuff - I like the smart effector or the toolboards because it helps to have a clean setup.
I searched a 12v or 24v version of these fans but I have not found any.

I found two 12V fans the same size, but when I tested them neither gave the same flow rate as the 5V one. So I ended up using the 5V converter that was supplied.

@dc42 Thank your for the prompt response!
I am really happy to have the confirmation this is moving forward, I am sure many of us are really impatient to have new features.

I think the CAN bus will be a great addition, I was thinking to rewire one of my delta to move all the electronic in the bottom with a toolboard as a relay on the top but I will just wait.

Can you share some more specific details like config files and macros so we can see what is actually going on?

config.g, homedelta.g, bed.g, and the results of M122 and M98 P"config.g" are a good start.

@dc42
No need for apologies! I am very happy with responses and working with me to figure out what was going on.

Great! thank you.

@andy_m Sorry, found it on E3D 🙂

@blt3dp yes that one is suitable. They are also widely available on eBay. The one we use is a compatible connector made by Wurth Electronics.

Thank you for the quick response! Sounds like ~50-60C would be the reasonable target then.

@dc42 You had right! Mi wires was connected in proper order but, for some reason it doesn't work. But I use different wires, crimped again and everything works 😄

So now I have been playing around and at last found the cause I have had with jumps/stepovers.
It all boils down to acceleration down from Hxx and M558 R/F value and M672 S105:xxx:xxx

The weight of what is hanging on Smart Effector must be tweaked with settings, time consuming but necessary.

Here my settings just now, may change after some more tweaking.
M558 P8 R0.6 C"probe+servo0" H20 F250 T3600
G31 P100 X0 Y0 Z0.865
M557 R85 S15 (I have now full factory spec for print area)

M672 S105:018:237

@cdoe You don't by any chance have a link to the resistor that you bought?

@jay_s_uk Pin 8 is getting 5v, and 24v to the 6pin

For anyone wondering, this is what I'm concerned about:

@cadu Checked the effector under the scope - solder looked good except for fiber microparticle debris and some surface oxidation that was causing the initial inconsistent probe readings. Reinstalled the effector reporting errors and it performed as expected, with 3 45-point mesh probes completing without "inconsistent probe reading" error and without the double parabolic shape.

G29
45 points probed, min error -0.165, max error 0.116, mean 0.001, deviation 0.057, with all 3 sets within 0.006 of those readings

My best estimate atm is that the increased speeds, acceleration, and short high-g movements in the input shaping tests after updating the firmware created the hidden hairspray/microparticle bead on the hidden idler pulley. The parabolic bed shape completing without reporting errors was probably the intersection of probing coordinates and the belt bumping over the bead. Prints didn't show the error due to the longer movements flattening the bead.

@barracuda72
The Overlord printers sound like that from new; the linear guides are pretty good as long as you keep them lubricated, twin rods with long bronze sleeve bushes.

I've always thought the noise was due to a lack of or primitive microstepping in the control board & motor drivers, plus the long guide rod design means there can be some lateral resonances.
(The machines were launched on Kickstarter in late 2012 or early 2013, if I remember right, so the electronics are fairly primitive compared to a Duet).

@baenwort said in Molex Microfit (or compatible) for the Smart Effector V2 or V3?:

I feel that universal crimps give poor results more often than good

What do you consider to be 'universal crimp', Engineer like tools or also their party ratchet crimpers?

Perfection is often prohibitively expensive and cupeled with an all-or-nothing approach we end up with nothing.

@bberger I have the same problem with increasing the 12mm gap but keeping 55mm arm spacing. My 'solution' is to cut the clip off the connector - I use a pre wired strain relieved molex plug which has a very tight fit, which I am sure is not going to come adrift.
