3018 Y-Axis Extension Kit, 3018 Accessories Upgrade to 3040, Compatible with Most 3018 CNC Router Machine, 3018-PRO&3018-MX3

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.

Arrived in perfect condition. Installed easily.

The 3018 PROVer V2 is an amazing little machine and now its an amazing much bigger machine! The kit was easy to insatall and really let us take projects to the next level (and make 4 small projects at once for our kid groups!) Sainsmart has some amazing products and customer service that is beyond reproach.

I was waiting for this kit. I bought it with the 20000 775 motor, as offered by Amazon. But, contrarily as it is said, it won't fit the frame for one of the main 3018 machines, the 3018-pro from the same brand. In that machine, the round guides are the same length as the aluminium frame, but in this kit, the rods are maybe 1cm larger. You would need to made holes in the frame to fit the round guides, or cut the tip and make the hole deeper.

Upgrade kit recomendable

Unlock your Y travel with this upgrade, it's fast and easy. Greatly increase the Y travel on your 3018. Installation was a breeze, the kit came with a longer Y limit switch cable. I purchased this with the Genmitsu T-Slot Table 3040 Extension Aluminum Spoilboard. The difference is night and day. I'm able to work much larger pieces and completely satisfied with the purchase. One reviewer wrote something about having to cut the rails, not sure what they did wrong, but I didn't have to modify anything. I have performed a few other upgrades to the CNC but this one was by far, the most useful. The upgrade with the 3040 extension will take you about 25-30 mins to convert your 3018 to a 3040. If you're looking for more Y axis travel then get this upgrade, you won't be disappointed.

Installing the Y-axis is an easy process, even with Sainsmart/Genmitsu instructions. Anyone that has seen their manuals knows what I'm talking about. They aren't very clear, but they'll get you there. The T-nuts don't fit the slots well, making the process more time consuming than it should be. After reassembly, the Y-axis is 33.8 mm or 13 5/16 in, or about double. The extra length is nice to have. As for CNC operations, change your work area/ material dimensions in the program. The ability to make larger creations also means completion times are longer. Depending on the level of detail desired, material size and thickness, the 3018, even with the Y extension, is just another tool in my box. I am mystified that Sainsmart's order page say it's discontinued and out of stock, but Sainsmart sent it to me when I ordered it through Amazon. It even arrived a day earlier than the arrival date predicted.

As expected, good quality, delivered on time, no problems
