I’ve had to replace limit switches a couple times over the last few years and it’s never been an issue. Plugged in a new switch and the light toggled when I put it close to steel, but when I installed it and plugged it in and initialized it just went red and stayed.
The errors are:
GRBL Error: Homing Failed, pull off didn’t clear
Homing Cycle Failed
Limit Switch Error (X)
Sounds like either a faulty connection, wiring fault, or bad switch — if it’s still in warranty, let us know at support, if not, we have replacement homing switches with wires of the appropriate length with the right connector for the SO3 in our shop.

Okay thanks, I’ll order another switch
Seems that I have a similar problem.
Machine stopped carving in the middle of a project.
I went to initialize and the carriage does the jitter bug on its way to the top right position. Then it simply stutters until it is turned off.
Error Msg: GRBL Alarm 6
Homing fail -Reset during homing cycle.
Any Idea?
I always start by unplugging the power supply from the wall and the machine, then waiting 20–30 minutes, then plugging things back in — if the power supply lights up promptly and stays steadily lit, then it should be okay.
While I’m waiting, I slowly and gently move the machine to the center of motion for each axis by way of the entirety of the possible range of motion at each end, ensuring nothing interferes or hangs up, and that there aren’t any spots where things don’t line up/work as expected — esp. for the Z-axis w/ a Z-Plus or HDZ, move it all the way to the bottom, then back up to the top, then to the middle.
Inspect all the wiring and hardware, verifying everything is in good condition and secure.
If need be, lubricate:

Once the machine is powered up, test each homing switch — if everything checks out, try initializing.
c.f.,
Thanks Will,
I did all that you suggested.
I tink it was the router power cable interfering with the x axis homing switch. I moved it and all seems OK.
Now on to V Carve issues. I’ll look in the forums. I just can’t get a clean carve. It’s been trammed well and on a sturdy platform. Tried many bits but still fuzzy internals. Funny that clean up takes longer than the carves.
Usually, fuzzy V-carves are caused by the wood species used.
Running a full-depth finishing pass after can help though — esp. if you spray w/ a hardening laquer while the stock is still secured on the machine and allow to dry before running.
Thanks. Gotta be a better way than spray with lacquer and waiting. It seems that woods like Pine and most hardwoods and even plywood that I use are pointless to use a V bit with the machine. I’m sure others have had good results. I just don’t see the secret sauce. I’ll look into the finishing pass thing again but I have had no decent results in the past. I’m to picky perhaps. Haha. I may consider some plastics, Nah. Just shape cutting may be in my future. Even then, the offsets seem silly, even for straight cuts. .004 per pass, why?
