Review: Can be adapted for a 3018 Pro Max - I bought this to extend my Genmitsu 3018 Pro Max. I have not seen an extension kit for this model yet. Knowing I would probably have to modify it a little I took a shot. The main modification was for the linear rods. They are 3mm too long. You can cut them off if you have the tools. I did in my lathe. But you could also drill a small relief pocket on the end plate on the inside to make them fit as well. The other modification is for the Carriage mount. The kit comes with 8 holes per side, drilled and tapped into the side rails. the 3018 Pro max only has 6. I used the old rails as a template and drilled and tapped the 6 holes between the other 8 and it works great. I now have a 3040 Pro Max. Next step linear rails on the other axis'. The wiring you will have to figure out for the limit switches on yours. I added them to mine. Good quality kit, for a good price & has all new bolts and a snap in wire cover for the rail slot.
Review: 3018 v2 3040 upgrade - Arrived in perfect condition. Installed easily.

A: I don't think this question got to Amazon. But I have seen where products go back in stock at sainsmart and eventually back in stock on Amazon.

A: This extension kit works with most 3018 CNC. Please refer to the model selection guide to see which model suits your 3018 CNC.

**Q: What size is the  actual work area increased to**
A: The y axis extension kit only expands the frame. You need to also purchase an additional T slot spoilboard kit, this will double the Y axis workspace.

**Q: My cnc is a 3018pro (not prover) will this kit work with my machine?**
A: No, the Kit for CNC Router 3018-PROVer/3018-PROVer Mach3 could not work with 3018-PRO. You would need to choose the kit For Router 3018-PRO & 3018-MX3.
