Reviewing the software we do not appreciate any major defect so we analyze the mechanical design.
The belts were tight and the motors adjusted to the correct current.
The guides apparently swinging well.
We were searching what could happend in CNC forums and we found that is a frequent problem generated by belt backlash.
It usually happens when the motor change direction.
But belts were new and properly tensioned so we could not improve too much.
Finally we modified the firmware in order to compensate the backslash.
We add a few extra steps to the motors when they change direction.
This type of adjustment is usual in CNC software.
The other problem was that at certain speeds the lines appeared as bitten.
