Has any one ever had one of their limit switches from Carbide 3D break? I did the XXL upgrade last week and installed the limit/homing switches (after having to adapt it to my Ver1 end plates). Everything worked great for three or four jobs, and now the Z axis limit switch doesn’t work. I took it off, and the “button” is broken off inside the little cover. It never was bumped or slammed into in those jobs, just used for homing and a couple of pauses.
Where can I order new switches (without the wiring) so I can keep a few on hand if this happens again?
And, yes, I will be contacting carbide 3d support, but I am still waiting to hear back from them on two other non related issues, and still waiting on the replacement motor extension that was DOA that was shipped Fedex Ground…
The limit switches are kind of fragile. They seem to also have some sort of manufacturing gunk in them that requires them to be clicked a few times before the contacts wipe enough off to start working well.
I know this is an old topic, but these are the worst limit switches ever. It seems if I don’t use my machine for a month or two they break right off when I fire it up – yes they have literally broken during a homing process. I’ve gone through several, all on the Z Axis, over the two years I’ve had the machine and I treat them very gently. Add to that they are $6+ a pop, plus shipping.
[by “break right off” I mean “right when I start a job”, not as in “off” the machine]
Yes, I agree, it’s a switch and should not be that complicated or fragile. Electronic failure, as in the switch is stuck on. It seems to happen after the machine is not used for a few weeks. I had supposed it had gotten gummed up with small particles and during previous failures and I had tried fiddling with the switch for a few minutes (which according to the s.o. was actually hours) to see if I could un-stick it to no avail.
Yesterday, the events leading to my frustration, I was able to home the machine, start a job, stop it (to change feed rate). Then when I restarted to home it again, poop.
I checked my order history (thank you amazon) and this is the third z-limit switch this has happened to. I was willing to accept one as my fault, one as a bad part, but at three, I’m suspicious.
I checked the troubleshooting guide and believe I’ve got (well not at the moment) the switch installed correctly.
I’m now playing the waiting game for the replacement from mouser to arrive. I ordered five. Hoping perhaps their quality is somehow different from the ones I got on Amazon.
well i have had the same problem with shapeoko limit switches. they are very fragile. not happy, I’ll have to try to find some maybe on Amazon where i won’t have to a long time to get it. Any body have a good Amazon link for a switch?
