This morning I go to load our Epilog FiberMark 20W system like any other day. Load the Corel program, trace the perimeter of the part with the red laser pointer, and everything looks good. Re-print in Corel with Raster settings and let the machine do it's work like it does everyday.
After 30 seconds, I hear the carriage smacking into the left rail and can visibly see the engraving missing it's target and shifting left. I hit pause and reset.
Go back to Corel and re-print the vector outline to re-trace with the red laser pointer and notice the x-axis has shifted to the left 3/8".
I turned off the system and rebooted. After it loaded, I re-printed the outline and everything was fine; both x- and y-axis locations were good. Before ruining more parts, I re-printed the drawing on Raster with the door open simulating the process. I no longer hear the carriage knocking, but after a minute, I hit pause and reset. I notice the "home/reset" position isn't normal, so I re-print the vector outline. The x-axis has shifted again to the left.
I can reboot the laser and everything is fine.
What's happening?
Side note, last Friday and cleaned the system and removed the yellow Epilog rail cover to grease the top bearings. I moved the carriage around by hand to work in the grease, but I've done this before and haven't had this kind of problem.
I thought maybe I put the yellow rail cover back on to tight, but I removed the cover and repeated the steps outlined above. Same results.
Why is the x-axis continually shifting left during raster, but a reboot will get it back in place just to shift again during a raster print?
TIA!
