My laser goes 45 degrees instead of 0 and/or 90.

Hi,

I have an Elekscam laser printer and it worked fine until last week.

If I navigate on the control panel to X or Y-axis the laser moves +1 X and +1 Y-axis instead of only +1 X of +1Y.
Also when starting engraving or cutting the image will be printed 45 degrees from the homebase.

I used the EleksCAM control software and the LaserGRBL software to see if the problem is in the software, but both programs give the same output.

Can someone help me out to fix this, so the laser goes straight over the x- and y-axis?
