I'm torn at the moment between SFU 2510 from BST Automation or DFU 2510 from Linkcnc, both on Aliexpress.
I've heard some good things about BST Automation, but I haven't heard anything or seen any posts about Linkcnc from Aliexpress.
I have come to realize that some suppliers make sure their screws are straight, and some expect the customer to straighten them if they are bent. I don't want bent screws or backlash.
Anyone want to offer an opinion about their experiences with either of these two companies?
