Zesty Nimble Smart Effector mount

17/12/2017: Update. Unfortunately, this experiment did not work out as planned. I've encountered an unexpected problem that interferes with the Z-probing sensitivity. It seems to be caused by the PTFE tube, which is just the right length under the Nimble. When the probe tries to raise the PCB relative to the Nimble, it compresses the PTFE tube and prevents the Z-probe from triggering. Removing the PTFE tube helps, but it introduces other issues as well! I'm terminating this experiment as a failure because there was no significant improvement in print quality anyway. I'm leaving this project here in hopes that someone else may be able to overcome this problem and continue developing it further. However, I don't plan on doing any more work on it myself. 16/12/2017: After using the Zesty Nimble mount for the Smart Effector designed by Lykle without issues for some time, (https://www.thingiverse.com/thing:2453322 ) I read a report from someone who felt that the Nimble mount was causing unwanted movement of the nozzle. I became intrigued by this idea and decided to design a new mount to isolate any potential movement of the Nimble from the PCB and thus from the nozzle. This is purely experimental, and I don't expect major print improvements or anything - the Nimble / Smart Effector combination prints very well anyway. The logic behind this potential problem goes like this: - There's a flexi PCB designed with some flexibility for the Z-probe. - There's a possibility of horizontal force from the resistance to movement that the flex drive cable has - even inertia. - The flex drive cable is about 40mm above the PCB, so the lever is about 40mm long. - Any horizontal movement will be transferred to the heatsink and nozzle through the Nimble, PCB, heatsink, nozzle chain. - The nozzle is about 50mm below the PCB, so any movement at the top of the Nimble would be amplified about 25%. - Any deviation of the nozzle from its intended position could contribute to lower print quality. Again, I'm not trying to solve a problem here - this is experimental. If there's an improvement in print quality, it will likely be small, so there's no reason not to use Lykle's mount. Having said that, this one is a finished product and is currently mounted on my printer, which is printing very well indeed.
