So its been a while since I’ve updated you on the status of my predator. Since changing over to a duet, I have a number of further changes to my machine.
The upgrade I’m going to concentrate on in this post is the installation of a duet smart effector. With changing this part I am also forced to upgrade to an E3D V6 all metal hot end, which for me is better, as the one supplied by anycubic is limited to a maximum temperature of 260 degrees Celsius.
So what does changing to a smart effector gain you? I would say there are three main advantages.
- It makes it easier to change your delta arms to mag mount versions later down the line of the type produced by Haydn.
- The hotend is now the Z probe. The smart effector has a piezo switch built into it that then uses the pressure of the hotend touching the bed to trigger it. This allows you to call a probing routine whenever you wanted without having to install an extra switch.
- The smart effector is made from a PCB so it is nice and lightweight but also strong.
To be able to use the smart effector with our machine, a number of extra parts are required if you aren’t going to be changing the arms straight away. I’ve modelled all of the parts required and made them available on thingiverse.
You’ll need to print
- 1 x converter
- 3 x fan brackets
- And 1 of each fan duct. It’s designed in a way that you can choose how many of the fans you fit. I have all 3 installed on mine.
- You’ll also need
- 12 x M3 nuts
- 12 x M3 x 20 screws
- 6 x M3 x 6 screws
- 3 x 5015 radial fans
- 3 x M4 x 30mm screws
- 3 x M4 nuts.
Make sure you’ve assembled the smart effector as instructed on the wiki.
Start off by running a tap down the 6 mounting holes in the converter for the smart effector. Then mount the smart effector to the converter and secure in place using 6 of the M3 x 20 screws. They do thick out the underside of the converter a fair bit, but that is because we will use them later to mount the fan brackets. Now mount the converter to the 6 arms using the other 6 M3 x 20 screws and the 6 x M3 nuts. You can do this either with the arms attached to the machine or with them removed. Make sure the screws are done up nice and tight so they don’t come loose. Then tap the 2 inner holes on each fan bracket using an M3 tap. Mount the fan duct to the to the fan bracket using the M3 x 6 screws, followed by the radial fan to the bracket using M4 x 30 screws. Repeat for the other 2 assemblies. Finally, mount the fans in the correct position under on the smart effector. Each fan should be wired in parallel and plugged into the part cooling fan port on the smart effector. See below for photos of it installed
For the wiring on the predator to the smart effector, I actually ripped out what was originally there and installed a new harness. This is due to requiring extra cables etc. Just follow the guide on the wiki and you’ll be fine.
Also remember to make the changes to the firmware for the probe and to retune the hotend using M303.
