Almost no wiggle (with comparator fixed on the structure, only 0.02mm) , only when I force, I start to bend the 8mm axis.Quote

how much play is there from tip of nozzle, is there any wiggle when the motors are powered up?
Distance between center of axis rod and nozzle tip = 32mm.Quote
is there any slop in the bushings or bearings, and how far from the bed is the carriage. normally you want it really close to prevent the slightest slop from having an effect on print position.
So i don't want to make "ad" for my project but there is some photo there:Quote
also do you have a picture of your setup?
Nop it's a real CoreXY (two belts, one crossover), and not a Hbot one(one belt, no crossover)Quote
. i would assume corexy is the H bot style.
GT2 belt (I thing it's polyamide inside and not kevlar). I have two tensionner, one on each belt. (screws + bearing + arm method)Quote
what kind of belts are you using to hold position, are they Kevlar reinforced? how tight are the belts, and do you have the ability to control tension on them?
All pulley are level, there is a little shift when travelling, but as everytime, why Y axis and not on X axis.... (I can't feal/measure moving part, when I move 0.1 after -0.1mm distance only on Y)Quote
is your belt drive level throughout the range of motion for the carriage, the belt is level and same height throughout the travel?
First post of my thread on reprapper channel.Quote
again a picture of your machine may help, some one likely more knowledgeable than me will have an answer for you!
