Smart PCB effector
August 14, 2017 04:19PM
The Smart PCB effector is now available from the duet3d web shop, [www.duet3d.com]. It includes a strain gauge nozzle contact sensor (Z probe), connectors for the contact sensor/the/PT100 and for hot end heater/fan/lighting/print cooling fan, and LEDs to let you know what is going on. It's compatible with the E3DV6 hot end, magnetic rods and ball studs from Haydn Huntley, and linear rail sliders or wheeled carriages with 20x20mm fixing centres.



It's Open Hardware so the source files will be published within the next few days.

Yes! I've been waiting to see how this turned out. I don't yet see it on Filastruder for US distribution. Will Tim be getting any in for us yanks? On your sales site, I was going through the checkout process to see what a final cost as configured would look like. I'm getting a mandatory field to purchase an e3d v6, but I already own a few and don't intend on purchasing another... The text implies the base price includes a unique heatbreak but nothing else, which may not be correct. Did you intend to require the purchase of an e3d v6 with each order? If not, give us a "Heatsink only (included)" option in that drop down. Hope this helps!

Just leave the options box saying "Please select" to buy it without extra E3D parts. I expect Tim will want to distribute it.

do you sell you kit without the e3d v6 heatsink (produced by e3d on our behalf).?
i have already many heads so no need to add extra cost on my finall list which is already expansive lol

The heatsink is a custom one to fit the effector, that's why we include it with the kit. There wasn't room on the effector for all the stuff you need to secure a groovemount heatsink.

Just placed my order. Very excited. Is the piezo somehow integrated into the pcb? or do we sandwich one in between the bolt and heatsink?

Do you have an stl for those carriages, or are they included with an order (The plastic parts, not the pcb)

I think it is an accelerometer and not a piezo... maybe wrong tho

You are both wrong, it's a strain gauge.

If you mean the carriages in the photos on the wiki page, they are Robotdigg metal carriages.

what kind of IC is it?
Re: Smart PCB effector
August 16, 2017 04:50AM
A strain gauge isn't usually an IC, it's typically a metal foil mounted on a substrate. We have 3 ICs on the effector to manage it: a voltage regulator to provide a clean power source, an amplifier to increase the signal, and a microcontroller to process the data.

Can also say having had one on my delta for some time that it works extremely well and routinely calibrates to less than 7 microns. and I also know that I could spend a few hours on the printer improving the geometry but it would be hours and probably wouldn't get it much better than it is.

Mine is fitted with a Zesty Nimble RDD Extruder and total weight of the whole thing is around 155 grammes

Picture of what exactly? if you mean the strain gauges then they are actually designed into the PCB Traces so not much to be seen on a photo (They can be seen as very fine traces in the copper by eye but they don't show up well on photos)

Oh, ok. I didn't know they were printed on, that's pretty neat... does it detect change in capacitance?

There are 6 of them in total and they detect very minute flexing of the PCB when the nozzle touches the bed I am getting sub 7 micron deviation on a autocal usually it is more often around 3-5 microns.

They work extremely well. and they are well worth the cost of £45 plus carriage and tax's were applicable, especially when you consider that they include the custom E3D Heatsink assembly.

Are there other version planned? For a Diamond hotend? I've seen the "dumb" PCB version for the Diamond and it looks very promising.
Not sure, how the strain gauges would work then...
Re: Smart PCB effector
August 20, 2017 12:21AM
I'm looking at a version for a Diamond hot end (as you say, the main design issue is how to get enough reading from the strain gauge elements) and a version for a Cartesian/CoreXY printer to carry a modified Titan Aero. But they won't happen very soon.

I am finding the smart effector works very well with Traxxas arms, if you don't want to go for magnetic arms immediately. I put my attempt at mounting posts on thingiverse (2492092). Getting very flat mesh calibration and accurately sized prints. The probe works wonderfully well.

That's good news!
I had trouble with my Kossel XL because of the Traxxas with 6mm rods and the weight of the Diamond hotend. It worked well with a single direct drive extruder, tho...
Now I could fit the current smart effector version with a Volcano hotend and upgrade later with the Diamond version and Mag-Rods. ( hope the magnets are strong enough for the diamond? )

In another thread I mentioned powdermetals cycloidal direct drive extruder.
I'm wondering if it would fit on the PCB like that? The gearbox housing could be redesigned to replace the nut. But it would be even better to fit the heatsink above the PCB and clamp it down with the M6 nut off the heatbarrier.

Are there any other sources in Europe for Haydns mag-arms? It seems David is sold out on 360mm rods?
Will you get some stock anytime soon?

Best place to ask is probably [www.duet3d.com]. The stocks are held by T3P3. I think more have been ordered but I don't know when they are due to arrive.

Just went through this. This embedded strain gauge strained me to discover it ! Really smart indeed.

How are they arranged ? 6 ? What bridge?

That I can't answer but the arrangement of them is 3 on each surface of the PCB at 120 Degrees apart and are actually part of the PCB Itself coupled with I believe a Rectifier/PSU chip and Amplifier and a CPU of some sort to actually hold the software that does the comparisons you would need to ask DC42 for the finer details or wait for the files to be released on Github if they haven't already

Hardware part of sources is already available: [github.com]
But I did not find part numbers of some components such as OP amp or LDO in SmartEffector_Schematic_v1.3.pdf file.
