Congratulations!

I have some advice regarding the belts. It's important that the belt is anchored at the same height as the top of the idler, so that the belt remains horizontal and the tension doesn't vary as the carriage travels. Then, you can tension the belt more firmly, which improves your accuracy.

Don't be surprised if you find that you need dual Y drive to maintain accuracy when cutting. Your "hello world" shows some Y racking; cutting wood is going to be worse.

Thank you!

I did find the unpowered side lagging and resulting in backlash while cutting wood. I changed the cutting depth to 0.02" and the feed rate to 20 and that seemed to help.

I will put improved belt tensioners on the ToDo list.

I think If Im going to go for dual Y drive then I might as well up-size in the process so I am researching that.

Thanks for the advise!
