Isn't it compatible with the newest Merlin-software?

Take a look here, the head moves very strange and slow in the inner corner-radiuses there, is this normal?

I'm using 0.1mm i Z-lift, has this influence on this?

I turned the model 45º, but the problems seems to persist. I also tried to fix the model in Netfabb, but same result. I will download the latest version from Lawsy and add the backlash.

What could cause this? The head goes very slowly in those areas.
Perimeters: 70mm/s
Small perimeters: 50mm/s

Maybe try to tightening the belts...?
