Testing process

Failures that were fixed while testing
Proper belts tightening
Adding 1:5 gearbox on X axis (2 motors)
More rigid cable channel mount
Additional lubrication of bearings on X axis
Installing the stud inside the flange from the engine to the gearbox
Added inversion of rotation of one of the engines along the X axis for the correct movement of the portal in the same direction.
Correct coefficients are set for step values along the X and Y axes to ensure accuracy of movement.
The correct size of the working field is set to prevent it from exiting.
The operation of emergency limit switches on the X and Y axes was tested.
The software protection work on the voltage on the MO2 board is disabled to ensure the operation of 2 lasers.
Additional stretching belts
Second bearing improvement
Stationary belt tensioners were made and installed to adjust the tension
Fixed scrolling of drive pulleys on the X and Y axis.
Major checkpoints tests
Max speed10m/min
Max weight10 kg on a X and Y
Vertical workdid not test
Horizontal worktested
Non-stop operation4 hours
Accuracy0.1 mm
