Hi,
I replaced gt2 belt with GT3 3 mm pitch 3mm. now i have a problem with 0.5mm backslash.
Do I try to replace a pulley or belt?
Any advice or help?
thx

Looks more like a calibration issue.
If the belts have been stretched, youâll see that. Maybe an upgrade to belts with a steel core if youâre looking for that level of precision.
What do you mean?
Tell X-Carve to move spindle in X Y or Z direction, it should move exactly 22mm if you tell it to move 22mm. Moving back and forth only 21mm instead will give the results your video showed there the roller wasnât turning all the way back to the exact same spot. It appeared to be just a bit âshortâ of the intended distance.
Thereâs lots of threads here about how to calibrate your machine.
Problem is backslash o pulley. I try replace new belt and problem is not fixed. I try also belt tension, am remove idlers amd add one bearingâŚbut all without good result. This gt3 is crapâŚ
Did you install new GT3 pulleys at the same time as the belt and got this much backlash?
Thx for replay. I changed the belt and pulley. All parts is are from the same supplier - china
@Traxxtar This wouldnât be a steps per mm setting. Regardless of the distance the axis moves, it should (ideally) return to the exact same spot when told to move a distance and then back the same distance.
When the pulley changes direction, any âslopâ in the interface between pulley and belt will show up as backlash before the teeth fully engage again.
