Hello.
I am interested in two of the following Ball Screw Z Axis assemblies:
CNC Z Axis Slide 7 75" Travel Ideal for Big Router ballscrew and Supported Rails | eBay
Rovercnc Z Axis Assembly Heavy Duty 7 87" Travel Anodized Red | eBay
As I lack the technical knowledge and I'm sure most of you will have a far greater understanding than I. Please let me know your opinion about these items. I am also open to any other suggestions of Z Axis assemblies from other companies. These are the two that I have narrowed down to after a couple of days searching.
I do like that both use supported rails. But I have noticed that the first item uses a solid coupler which is not to my liking but haven't decided if that is a deal breaker yet.
A little info of my application:
This axis will be used on a 4' x 8' flat bed router gantry.
Primarily used for routing on wood, acrylic, and some aluminum.
Router used is a Porter Cable 890 variable speed.
I appreciate your information and help.
