i still search good mount for my ender 5 if you have one for me i can test it

I'm very happy with final iteration of my mount on my ender5... It does require a linear rail on the X as everything I tried with the original X slide I didn't like so I added a mbn12h on the X and designed a carriage (this is 4th iteration with bmg, I also have one with flex3drive g5 but I moved g5 to my e3d toolchanger so running ender5 with bmg+e3dv6)

linear rail is not the problem the problem is i have the micro swiss all metall hotend

if you look at the mount the hotend is on the other side of the ppiezo disk so existing plate holding hotend should work with that mount

I am making progress !!!
Having thought about it (i.e. went to bed) I decided to increase the F value from 400 to 600. I.e. faster approach speed. It looks to have got rid of the multi-probe not converging issues and can now see what looks like a reasonably good mesh. A little "tuning" of the bed leveling nobs and I should be good to go.
Will report back as I continue to debug. As @arhi pointed out - time (and some sort of change) will tell .....
@lui2004 - I think the mounts that I pointed to (in the other thread) are probably robust enough and have the advantage of being quite compact and using otherwise stock ender parts. At least I do not think the mounts are the source of my initial problems. Note that I printed my (slightly modiefied) top mount in PLA for rigidity and the rest in PETG for temp resilience.

I spoke too soon
The precisionpiezo is fine in theory but, in my view, misses terribly in practice. Having just spent another few hrs when, I thought I had it working, only to have it go sideways again ..... I am literally pulling the plug.
I do not give up easily but the hours spent on this are not worth any claimed precision because the repeatability is simply not there. Its a good idea that simply does not live up to the claims (implied or otherwise).
Yes - I was warned but had to find out for myself .....
I have joined @arhi and @jens55 - just ordered a replacement for my trusty BLTouch (that I broke being ham fisted). I will now gladly put up with the probe being offset from the nozzle and not being able to probe the entire bed because it simply works "good enough". The precisionpiezo certainly does seem to be a case of "better is the enemy of good". Hopefully in some future iteration it will be worth revisiting.
I wonder if PP will refund me for the Orion board? Other than having been "clamped" it's effectively unused and good as new
-
P.S. Since I have my eye on a Zesty Nimble - I also doubt that the PP could cope with the physical "noise" of a co-located extruder ....

co-located extruder
I used it with flex3drive G5 (zesty is a clone of flex3drive) and had no issues with it. Basically, while you are probing you are not extruding so no matter what extruder you have or not have there makes zero difference.

I still have PP on some of my printers (ender5 is one of them), I hate having to set it up every time I rebuild the head but these days it's just the matter of finding the proper tension of the screws holding the top and bottom part together as since I replaced that cable and went with good coax cable and analog output I don't have any issues after it is properly tensioned.

@arhi - Thanks for the clarification. At $35 for a new BLTouch and my currentl hourly rate working on PP (about 35c per hour) .... well - you get my drift

I'm curious now as to the difference between Zesty Nimble and flex3drive but that's a different thread

yes, that is why I'm not using it for new printers

in 99.9% cases, this question leads to a flame war and lock of a topic so I'll restrain myself from commenting. I heavily tested both and can give you my own opinion (not affiliated with any of them) in private chat if you are interested
