I cant find an upgrade for a 43mm diameter z axis mount. Or am i missing something here?** A: Hi, Firstly the image shown is for the '3018-PROVer/PROVer Mach3/MX3', not the 3018 Pro! The 3018 Pro version is available on the same Amazon page as the 3018-PROVer/PROVer Mach3/MX3, to the immediate left of the rectangular box stating '3018-PROVer/PROVer Mach3/MX3', just left click on the to the left of the rectangular box & the page will update to the '3018 Pro version of this upgrade (same price). That said, you will need to buy a 300W to 500W spindle motor with 52mm body diameter to use this upgrade & discard your existing 42mm motor. You will also require a new separate power supply to suit the new spindle motor along with a PWM speed controller to drive the new motor. I have done the above upgrade for my 3018 Pro with 300W spindle motor upgrade, & now get really good cuts & finishes from my 3018 Pro. This does involve additional expense but is well worth the investment. Regards Laurence Barron **Q: What is the linear bearing diameter? I am looking to get this upgrade and I have 10mm stainless steel rods.** A: Hi, I ordered the Genmitsu Aluminium Z Axis Spindle Mount 300-500W Spindle Holder 52mm Diameter for the 3018-Pro, & its' linear bearing diameter is 10mm. In the same Amazon page as the the Prover version, lower down the description you will see selection boxes for either the 3018-Prover & the 3018- Pro versions, so depending on what CNC machine you have, simply select the appropriate box. I do not know what the linear bearing diameters are for the the Prover version, but the 3018 version are 10mm. I hope this helps. **Q: Will it fit a mostics cnc 3018 pro** A: It only fits after the bottom X guide was removed , then moved down in the Z direction by 1mm. Note that the 2 parallel X bars is to hold the Z axis module. (The gap is not wide enough). I originally forced it in.(BIG MISTAKE). I had to re-drill the side support holes for the bottom X axis shaft after filling the original screw hole with glue. The glue hardened and dried, then I drilled. The 1mm increase made the Z axis module travel easily. Measure the gap (exact centre to exact centre before installing). ## Frequently Bought Together - Genmitsu Upgraded Aluminum Z Axis Assembly V2 Kit, with Spindle Motor Mount for 775 Spindle and 300-500W Spindle, 43mm & 52mm Diameter Spindle Holder for CNC Machine 3018-PRO - Genmitsu GS-775M 20000RPM 775 CNC Spindle Motor with 5mm ER11 Collet Set, CNC 3018 Upgraded Accessories, DC 24V, High Power, Noise Suppression, Electrical DC Motor for 3018 CNC Router Machine - SainSmart CNC Router Z-Axis Tool Setting Touch Probe, Compatible with Grbl/Mach 3 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/523459295-upgraded-aluminum-z-axis-assembly-v2-kit-with-spindle-motor](https://www.desertcart.it/products/523459295-upgraded-aluminum-z-axis-assembly-v2-kit-with-spindle-motor) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-07*
