Thank you Zax for your reply.
I am new to laser engraving and just learning. Received and assembled my laser last Saturday. I now know how to send the command to x-reverse.
I consider the EleksCAM software should work and EleksMaker should fix any issues. It is part of what we pay for when we buy a device from them. Apparently the last release was done last year and no fixes since then.
I tried t2laser but gave up since any picture I tried to engrave was bigger than 10K lines. Even just a face, so no way to test it. Later I found LaserGRBL which worked great for what I wanted to do.
