Great choice the 1500x1500, the structure helds well the size. I can't aford bigger than 600 for the space I have avaiable. I have the OpenBuilds X32 control system. For grbl it's great. Easy, mostly plug and play, strong, very good g-code sender https://software.openbuilds.com/, fantastic comunity that can help you with anything, really. Have a look, it's worth spend some time on their site exploring the forums and documentation. For the rest, talk with Marvin, I think the owner, thru the Yuyong Industry site and tell him what you wish. He is nice and give you the prices step by step. You can literally make it tailored as you wish. Great to know someone that will have the same machine!! A lot to talk about....
