Zesty Nimble Smart Effector mount

17/12/2017: Update. This did not work. I've found an unexpected problem. It interferes with the Z-probing sensitivity. I think it is because of the PTFE tube. This is just the right length under the Nimble so when the probe tries to raise the PCB relative to the Nimble it has to compress the PTFE tube and the Z-probe fails to trigger. Removing the PTFE tube helps but of course introduces other issues! :-) I'm therefore terminating this experiment as a failure. If there was any improvement in print quality is was tiny anyway! I'm leaving it here in the hope that someone may be able to overcome this problem and continue development - but I don't plan to do any more work on it. 16/12/2017: After happily using the Zesty Nimble mount for the Smart Effector designed by Lykle for some time, (https://www.thingiverse.com/thing:2453322 ) I read a report of someone who felt that the Nimble mount was causing unwanted movement of the nozzle. Intrigued by the idea I designed this mount to isolate any movement of the Nimble from the PCB and thus from the nozzle. This is only to test and I do not expect major print improvements or anything - the Nimble / Smart Effector combination prints very well anyway. The logic of the potential movement goes like this: - there is a flexi PCB, designed with some flex for the Z-probe - there is a potential for 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 the intended position could contribute to lower print quality I say again, though, I'm not trying to solve a problem, this is experimental and if there is an improvement it is likely to be small so there is no reason not to use Lykle's mount. Having said that, this one is a finished product and is mounted on my printer at present - and is printing very well indeed.
