Summary

I used to have this cooling duct on my i3 which inspired me to design my own magnetic delta effector with a built in print cooling fan. I also wanted to put a capacitive probe on it, which it ended up in a pretty awkward position right in front of the E3D cooling fan, but it doesn't hinder airflow that much. All in all, I'm extremely pleased with the end result.

There are no nuts for the magnetic balls, I just screwed them right into the plastic and they sit pretty tight. Also be mindful that the arms won't hit the fan or probe when near the edge of the print area, but it should be ok. And lastly there doesn't seem to be any issue with the plastic (PLA) closely surrounding the heater block. I've been printing with it for many hours already.

There are a few versions, most have a spacing of 48 mm between the rods, one with and one without a probe. There is also one version which has a spacing of 51 mm. Step file now included as well.

Edit 26-02-2017: By request, I've added a version for KARM-06 CL Igusball bearings.

Really great effector you made :-)
I have modified it a little to change place for capacitive proximity sensor, and I will post a remix later :-)

What did you use to design this with? I am looking at mounting a piezo sensor on it (https://www.thingiverse.com/thing:2319993), but need to make some modifications to it to get it to fit. If you would be interested, I would be willing to work with you on these mods. I really like this design with the fan duct built in and had been planning on replacing the existing effector that I am currently using with this one.

Precision Piezo - Piezo20 Hotend Z Probe

Hello. Congratulations for the design! What is the distance between balls?

Thanks, the distance is 48 mm.

Thank you Nilz. I would want to take your design for my delta, but my carriages have 51mm. Should be carriage and effector same distance? What if I use them anyway?

Yes, they need to be the same since the 2 rods need to be parallel to each other. If they aren't then the effector won't stay parallel to the carriage which means the effector won't stay leveled when it start moving.

Your best bet would be to increase the distance on the carriage to match the effector since the balls can't be put closer together on the effector because the duct will be in the way.

Thank you again for your (fast) reply. My carriage is wider than you effector, so I would have to increase the distance of the balls in the effector by adding 1.5mm each side. Due to high precission is needed, I wouldn't want to modify the stl file using tinkercad or other. Maybe you can upload the source file? Thank you in advance

Sorry! I read that as 41 mm. I've added a version with 51 mm spacing between the rods.

Thank you VERY much. I will try it and tell you the result. Best regards

Hello. Thank you for the new model. I printed it. Design is wonderful. How did you manage to fix the hotend on the effector? I used the pieces you added with no result. Can you add a photo or instructions of the way of fixing, please? Thank you very much

You slide the hotend into the effector from the bottom. Make sure both the thermistor and heater wires are on the same side as they should lie inside the cutout on the bottom of the effector. Then you can slide the effector lock over the groovemount and then you can optionally put the top part on top of it. I hope this makes sense.

Hey,

looks really good! Do you have by chance a link for the magnets and arms?

From all the effectors I've seen so far bulding my two delta printers in the last 12 months, this is, by far, the coolest. If I find time to adapt and print (To re-use the magnets of my Kossel 800 effector), be sure I'll post the results! Great job!

EDIT. Wait a minute. Now that I thing of it. How did you set up that probe on your Marlin, I bought it but I never found the right Intel :-/ ?

Hi, thanks a lot!

To use this sensor, you need to put a voltage divider between the output of the sensor and the endstop connector on your controller. I followed the instructions in this video from Thomas Sanladerer which explains how to set everything up. Good luck!

Great, I'm all settled now, looks simple, and I got all the electronics needed. So, I'm the one thanking you!
