Hi, all.
I am assembling the 2.0 version of Felix.
The PCB of the optosensors does not mate flat with the z-axis-carrier so I am not sure how tight the screws should be as tight bends the PCB, and loose is no good either. There is no cavity to hold the thru-hole terminals soldered underneath...
I could mill these cavities but according to the assembly manual, you should put double sided tape under the opto-sensors. If this is meant to be a spacer then a modification to the plastic parts should not be needed...
(But what else would the tape be for? Isolation? Does the tape really needs to stick?)
Unrelated: As I go, I am compiling some notes with odd things I found in the instructions, design and mounting sequence suggestions etc. that I'll share when the assembly is completed....
I hope some is kind to answer fast!
Thanks!
Julian

Hi Julian,
mine came already assembled, so maybe i can help. I can take a close-up picture of that part tonight if you show me exactly where you have an issue...
i think i saw something like white double-sided tape under one of my sensor,..but not completely sure..

Thanks Hugues,
Attached are two photos of the PCB. You see it resting on the thru-hole terminals. I hope you see that the mating faces are not paralell.
I have two tapes* but none of them can fill that space. Much less when you start compressing them with the screws.
The other optosensor PCB on the vertical wall has the same problem.
* Carpet tape and Pattex "No more nails" tape. The last one is thickest, about 1.5mm

Probably these things will become clear when I finish the assembly and actually start using the printer. For the time being I am stalled waiting for a missing printed part to be re-sent...
But I'll share what I think: I guess the tape is a solution to fine-tune the position of the opto-sensor. By adjusting the tension on the screws you would align the sensor to the rib on the moving carriers.
