Thank you for the response. I slightly misquoted the error, it is more like "LaserPrintDriver Module is not responding"
I use CorelDraw and convert the file to a .plt. I then import the file to Lasercut and save as a .ecp file.
Another interesting anomaly is that even though I always save the file as .ecp when I download the file to the LS020 the display on the machine sometimes shows the file name I have used, but more often than not, just shows LASER.MOL even though it has downloaded the correct file. (I always delete the previous file saved to the machine to be certain it is using the file I want)
