Hi all,
It's been a few weeks that I noticed the weird shape of my V-curves !
I get this wth the EAF focuser (v1) on my TS 102:

...while with another Zwo focuser (v2), even though this is not at the same step, but the shape is similar, I get this rather familiar V-curve:

Yet, when I check with a bahtinov mask it looks quite good...
Will have to check again, now that I'm writing this post, but photos look apparently ok.
Is this normal, or are these signs of the onset of failure?
Thanks for your help
BTW : last stable firmware v2.0.10.46, I never use beta firmwares...
