There are quite a few optimisation techniques for etching larger areas. Depending on what you are planning you may want more info.
Also the best boards for etching are bamboo, and Wilko sell the cheapest.

What Arthur said! (My young padawan learner has been paying attention!)
I would always recoomend not running jobs with the laser at 0,0 for this reason. After homing the laser just move the head out at least 20mm in both directions, and that error shouldn’t appear.
If you are around either tonight or Thursday evening I would be happy to help.

Subject: Re: [RDG-Hack] Re: Laser cutting materials
I think that is an error when your working too close to the edge of the bed. When doing a scan cut, especially if it's quite high speed the laser needs a little room around the work piece to accelerate up to speed. Otherwise it would burn too deep at the start and end of each pass, as it slows down and speeds up.

Hi Tony,
I tried to laser cut. But it didn't work.
I did a scale cut - which worked fine.
But when I tried to cut the letters it said "not enough extend space". I've re homed and move the board I was trying to engrave on. I also typed the letters in RDWORKS. Incase it was my file. I got the same message about space.
So not sure why it isn't working. But don't think it's anything I did / am doing.
What do you think?
Thanks
Emma
