I have an 80w Rabbit Laser that the company I purchased from refuses to service (Refer to this post: http://www.cnczone.com/forums/genera...-warranty.html )
My laser will drift as it cuts which puts cuts out of alignment as the program continues. I also have serious jagged edges that I believe are a result of something bad in the X-Axis (You can feel the head vibrate when it moves in the X). I think the machine is losing steps due to this.
Rabbit Laser USA informed me that anything that electricity touches is not covered under their warranty, so I'm looking for someone in the area that might be able to troubleshoot the machine. It's definitely something in the controls or motor territory.
