I don't think that is uncommen. My machine did it when it was new, but now it doesn't slide down anymore.
The important thing is when you turn on the machine, the router or spindle goes up and stays up.

Thanks did you put something under it so the bit would not rest on the table or did you remove the bit each time before turning it off

Did you put something under the spindle to keep the bit off the table or work piece or did you remove the bit before turning power off

No I didn't! I always take whatever bit I am using out of my spindle after I am done cutting.
It's really nothing to worry about though.

The only time I've ever had that happen (z axis drop) is when my coupler broke, otherwise it stays where I left it, even for prolonged periods (I have 2 Axiom machines (AR4 and AR8, with the AR8 being used all the time and the AR4 less often).
If everything is good (coupler especially) I would take to removing the bit at night and letting the spindle/collet rest on the spoil board, or if you kept it, the round tube that the machine shipped with (to protect the spindle).

Or cut a toilet paper tube into two equal size cylinders, slit one lengthwise and glue it onto the inside one. Wrap it in tape and use that as a support...

In 4 years, I've never had the spindle drop. AR6Pro. I would contact Axiom, as it indicates a problem, to me.

I have this problem as well, although intermittently. Did anyone contact Chad and get an answer if it was a problem ... or there is a fix?

There really isn't any problem to fix. Some machines do it and some don't! If it's a bother, then do as others have stated just put a toilet paper roll or something else under the router or spindle and don't worry about it. Once you turn the machine on, everything works just fine!

It may not be a big problem, but I have to think that it is highly unusual for a machine to do that and there must be a cause. |

When I first got my machine, it did it just a few times and then stopped and has not done it again. That's why I really don't think there is anything worry about, but Chad would be the one to ask about it for sure!

I suspect it may start to occur as one's machine gets "worn in" and there is less friction to hold the spindle in place (with power off). Maybe that's a good thing? In that it means it moves freely, and there is no binding going on?
I think it would be a good idea to put a warning in the manual, so that if a person has a very sharp bit in there (I use 18 and 30 degree bits quite a bit (for fine lettering, etc) and if I were to shut it down and it dropped to surface of a valuable work piece (guitar for example) I know I would be nonplussed about having a deep hole in my guitar (or project in general).

This has only been reported on new machines. My guess is poor manufacturing quality control. No response from Axiom.

I've owned my AR6Pro for a little over 2 years now. I have a dust shoe and steel wire reinforced duct hose attached(extra weight). Z-axis started to drop when machine is turned off shortly after purchasing. I spoke with Chad over the phone about this couple years ago and was told not a problem at all as long as machine zeros out correctly when turned on and homed. I will frequently leave a bit in overnight so to pick back up where I left off. Never once had an issue with Z zeroing out incorrectly. I simply place a block of wood under the spindle every night.
I keep the ball screw well oiled and grease the bearings every 2-3 months. I do notice that the spindle drops depending where I park it and shut the machine off. If I park it with the dust hose stretched out and "pulling" the spindle does not drop. If I park it directly below where the dust hose is attached from above then the spindle drops every time.
Not a problem at all and I simply don't worry about it anymore.
