1. after the machine home's to the limit switches it tries to come back to the origin when I loose steps because it try's to fly there at high accln.
2. when i start a job it tries to fly fast to the start position where the stepper motors looses its steps.

meanwhile I was looking at what setting to make the laser fire in both directions, currently the laser fires when the axis is moving in only one direction.

When you are setting the speed and power for an engraved (or bitmap) layer, there is a drop-down box to select how you want that to work. You probably have X-Unilateralism selected. Change that to X-Swing.

sometimes I have seen it too that the laser during engraving only fires in one direction. I have x-swing activated

I have seen a measureable offset in the return that does not appear at lower speeds, so it can only be explained by either belt stretch or delays in firing the laser that do not have an effect at low speed. X-uni is a work around that fixes this error. I have seen that speed compensation can be entered into the controller to fix this, but I have never had enough time to figure out exactly what I need to do to make this correction so I can use X-swing all the time.
