Watercooled Smart Effector In Larger Effector || 4th Axis Design
-
Two days ago I printed all the parts I needed, sized correctly for a 25 mm bowden in between the hotend and extruder. After installing the parts it became clear quite quickly that 2 5mm is to short. For one, the wires coming out of the power connectors on top of the smart effector actually interfered with the bottom of the extruder. Secondly, 25mm is pretty tight in terms of bend radius near the bed edges.
Following this, I quickly changed some parameters around to adjust for a 75 mm bowden, reprinted the part and installed the revised extruder mount. The 75 mm seems spot on, not unnecessarily long and not to short. The total length of the bowden, including the part thats that reside in the hotend heatsink and inside the extruder, is now 127mm. Which is a nice improvement from the 305mm it was previously.
I will update this post should something noteworthy happen when I do more prints with this revised setup.

@Nxt-1 - Sorry for digging up an ancient thread, but your use of the smart effector caught my eye. I have a delta with incompatible joint spacing for a direct replacement and I'd like to mimic what you've done. I didn't see a note summing up how the smart effector has been treating you though.
Did you just screw the smart effector down in 3 places? Any special washers/spacers or slotted mounts used to ensure enough deflection?
How have the (bed leveling) results been? More consistent than your previous bed sensors?

@tgarr No worries about the thread digging, altough quite old, it is still as relevant as it was. In fact I just started a print with the exact same effector design as posted here. The 4th axis attachements are still evolving and I do have some minor changes planned to the effector design but noting major.
I don't use any special washers or something like that. Just the 6 screws (with a regular washer on top) that thread into brass heat set inserts.
In terms of calibration results here's the full DWC output string
. That is for a 180mm probe radius on a 400mm diameter bed.Calibrated 8 factors using 18 points, (mean, deviation) before (0.018, 0.046) after (-0.000, 0.043)The results are certainly more consistent across the entire bed compared to the FSR's I used to use. I am honestly not sure if the 0.043mm deviation is considered good for a 400mm diameter bed.
