Is there anyone or know someone who uses opto-endstops on a mendelmax 2.0?
I ended up using mechanical end stops on my MM2.0 and really like it. If you use an opto let us know!
I’ve used opto’s in motion control and I honestly don’t like them. They have much better reliability but they are such a pain to set as it’s not as visibly intuitive. Mechanical leaf switches are just simple and should be fine reliability for 3d printers
Hall effect endstop ! Super cheap, super reliable, super easy to use.
I just upgraded from my mendelmax 1.0 to 2.0 and I have opto endstops.
I’m searching now for mounts, because I’m happy with them.
Use higher quality switches or opto/hall endstops on Z-axis where added precision makes sense. Using these on X/Y is waste of money.
@Richard_Marko , I believe @ThantiK posted a video showing the repeatability of a mechanical leaf switch to be in the tenths range (.0001). I’m just really partial to mechanical switches as they’re cheap and the easiest to mount and tweak, since you can visibly see and hear the point of actuation, so it can be setup with no power if needed. Hall effect switches, I feel are nicer than optos as they are not susceptible to stray light noise, or mechanical failure of the beam break flag.
I could see using a hall effect stop for Z, but optos are just a big fat pain in the ass. Anything bumps the tiny little flag, and you’ve gotta readjust everything.
Use a mechanical switch for everything, and if you absolutely must, use a hall effect stop for Z.
Actually, hall effect are cheaper than mechanical.
You’re using the optos wrong. The flag should be an intregal part, inclosed in a box with a button that pushes the flag.
most optos are used in enclosed, dark spaces.
@Stephanie_A , I’m not following, how can the flag be an integral part of the opto, wouldn’t that just make it a mechanical switch that uses an optocoupler? The point of using an opto is to remove mechanical actuation for reliability purposes. I’ve just always found that i mess with the flag excessively and the alignment of my action is not perfect and the flag ends up colliding with the sensor.
TBH I’ve only really used them for R&D with rigged flags made of aluminum tape, and in production with somebody else’s poor design, albeit aluminum sheetmetal flags
