Hi all, I want to add limit switches to my X50 and I noticed that it came with some bolts that I can’t see any function for. I am hoping someone can support my idea of using them to mount the limit switches. They appear on all of the mounts in the right place, so . . . . . . (see pic) [TheBolt] …

I think that may be atramming bolt. [image] Tramming - Front To Back Rails There are a few methods to tram your machine. Loosening some z mount bolts, using 123 blocks, tram arms, folded pieces of tin foil, are all methods that can have acceptable outcomes. Left to right…

Hey Greg, [image] GregZo: [TheBolt] I would not touch that bolt unless you want to adjust the tilting of the rails . Retrofit proximity sensors (here: inductive sensors ) as limits switches are shown here (including 3D-print files) and here . Stall homing is explained here , the datasheet of …

Thanks Aiph5u, I won’t be adjusting them just now. I will make my own mounts elsewhere.

The Buildbotics forums have several posts about limit switches too

Thanks for the posts folks. I have purchased some small reed switches encased in protective casings that I hope to use as limit switches (see pic). I will make my own brackets for them and use small magnets to trigger them. Let me know what you think of this idea. [Reedsw]

Hey GregZo, reed switches are hermetically enclosed in glass cylinders so are dust-tight, not subject to corrosion and maintenance-free. However, unlike inductive proximity sensors (e.g. Omron E2B ), it seems their life is not endless: Life The mechanical motion of the reeds is below the fatigue l…

Hey thanks Aiphu5u, Next part- question: Here is a photo of the carriage and it has these two M5 bolt holes that are empty and don’t seem to do anything. I want to mount my limit switch magnets on them. Will this work? It looks like it will be fine but I’m asking just in case. [Boltholes]

Hey Gregzo, in these holes you find the grub screws that hold the linear bearings in place . You can put short bolts on top of them, but I would measure the depth of the hole to the grub screw beforehand so it doesn’t reach it.

I did the same thing to mount the trigger half of my proximity sensors. [IMG_1041]
