Ok, so i have one of the Chinese 40W lasers and for the past 10 months its been fine, I have read so much about the build quality but it has done what i wanted it to do so i am happy. But earlier today when i turn the machine on, instead of going to its starting point (0,0) it is just scrolling right on the X-Axis.

the Machine initiall goes to the top right. as it has done every other time ive turned it on. Then it steps a little inwards which is where it starts. But when its stepping in, something is going wrong and it wont stop.

I have taken the rails out of the case to see if i can clean it a little. but its made no difference. I will try and take a video now and upload but i don't know what to do.

Any suggestions?
Thanks
Scott
