Smart Effector including toolboard-capabilities?

[oliof]

@dc42 it could be used with the Galileo/Orbiter or Flex3Drive extruder drives which can be driven by a NEMA8 stepper and weigh in at 100g or less, including the stepper. Nimble v1 also can be driven with a NEMA8 (v2 cannot due to the changed gear ratio IIRC).

[dc42]

It wouldn't make sense to use a tool board with a remote direct drive extruder (Flex3drive or Nimble) because you would need long wires going back to the extruder motor. It would make most sense to integrate the tool board with the effector if the extruder drive is small and light enough to mount on the effector.

We have some work under way to reduce the amount of space taken up by the strain gauge of the effector, which would pave the way for adding extra electronics.

The nema8s are mounted straight into the extruders, no flex shafts involved, in the configurations I mentioned.

Thanks, those extruders look promising.

I like the look of the orbiter, i might have to get one to test on my delta

[dc42]

I have ordered an Orbiter extruder so that I can look into the feasibility of this idea.

awesome.

@dc42 if you ordered the blurolls version: Mine did come with off-spec holes for the axles since the original models are made for FDM tolerances but it's been made with SLS Nylon; re-printing the idler arm was sufficient to make everything fit.

What are you considering to be the idler arm? A picture would help.

I bought one from "sealander" (although they do say it is by blurolls) so we will see what happens in three months time, after it has been half way around the world on the slow boat from China

@CaLviNx Sealand and blurolls are one and the same. And you're right, there is no idler arm, on the thingiverse listing it's the Latch.

Thank you for the update, that was why I asked.
I have an adapter drawn up to allow fitment to the smart effector, I might try to see if I can sneak in a standard sized tool board (LC-1) in there too.

In what way where the holes off Spec (small or large)?

[oliof]

@Dougal1957 the holes are too large (4.25mm diameter rather than 4mm). I printed a replacement latch in ASA and the axles just press fit nicely.

[Dougal1957]

@oliof all 3 of mine came spot on both the 3mm hinge pin and 4mm idler shafts fit just fine so maybe they have tweaked there files to suit. All three did have packing issues mind the first came without the drive gears and the last 2 came without the feast couplings but Blurolls have sorted that issue out and I now have 3 fitted to the Jubilee ToolChanger

[A Former User]

Mine came in this past week with the shaft too small (2.9mm) and the holes on the arm too big (3.1mm)

[oliof]

@Dougal1957 good to hear they at least read my feedback (-:

[dc42]

Mine came at last. The 4mm idler axle wouldn't fit into the latch at first, I had to ream out the hole at one end of the latch a little and then use a hammer to tap it into the other end. I have one long M3 screw and nut left over - no idea what those are for.

[oliof]

I used the new bolt and nut to attach the latch and have a leftover axle (-;

[Dougal1957]

@dc42 yeah I to had a longish M3 bolt and nut left over on all 3 of mine but they all did fit together nicely

It's clear to me that the Orbiter could not be used with a Smart Effector made to the current dimensions. We would need to increase the rod spacing to at least 80mm in order to accommodate the various parts of the extruder. We are looking into this, however it would make it unsuitable for the smaller delta printers.
