ANNOY TOOLS CNC Z-axis Module Support 3018 pro, Spindle 300W/500W 52mm Diameter, Aluminum Slide with Nema17 42hs48mm Stepper Motor (with Motor, Run 85mm)

Heavy Duty full metal. No severe vibration with my 500W brushless motor even on 3018 pro extended CNC.The seller helped me through the problem I had attaching my brushless motor. He sent me for free, the metalic bracket that fits the module to attach my 55mm motor, because the kit I bought has a diameter of 52mm and I needed 55mm.I greatly appreciate his time and effort in solving this problem. By experience, it is hard sometime to keep good contact with a seller when the product is already sold. Thank you very much.

First off, the shipping speed was very much quicker than I expected so great job on that. Secondly I'd like to say this is an essential upgrade for a 3018 CNC Machine or similar. However I'd have given it five stars if it wasn't for this issue. When I received it the bearing inside the Z axis had lots of play/slop in it, however I reached out to the seller and they sent out parts to replace it. I replaced the part where the bearing is mounted in the Z axis and it seemed OK.After about 2-3 days I did some testing when I got the chance and I still notice that there's still some play in these replacement bearings but it is better than the previous ones. The bearing in the X axis has no play in them so I know the seller has atleast "some" good bearings.I was planning on reaching out to the seller about it again but I didn't bother because I think I'll likely get another faulty bearing once again. Having even a tiny play/slop in these bearings, will be much greater at the tip of the Spindle and cause cuts to be inaccurate. In the end it's a really nice upgrade, all aluminum parts and 10mm rods vs the 3018's 8mm rods. Just be prepared for those bearing issues, everyone's experiences with this unit might be different, I'm just giving my honest feedback about the unit I received. I'm not satisfied, but I'll work with it for now.[Edit]I'm now giving it 5 stars because the seller reached out about my bearing issue again and sent a replacement that he personally checked himself, I received it, did some testing and it worked flawlessly.

Everything works and is well built. One consideration is that you may have to adjust wiring to work with your motherboard, I had to swap red and blue.

Nicely machined, easy install
