This linear stepper drive was perfect for my particular machine. The guide is very tight and doesn't dangle. It also has very smooth operation. I really like the flywheel locking mechanism on the ballscrew. I contacted CNC Heechoo directly to get a different locking mechanism for a different part of my machine and they were very helpful in sourcing the parts needed. When the time comes for another machine, I will use more Heechoo CNC products.
