(read comment) - I received a new 4th. Axis from the seller, and this one works fine!...Kudos to the seller for sending me a new one even when I was out of the desertcart’s return window. After I opened the box and manually tested it I realized that the new one was able to spin without much effort, opposite to the first one I got that it was hard to rotate, but since I didn’t know what to expect I thought it was fine and hard to rotate due to the stepper motor (I didn’t remove it). So here is my recommendation if you get one of these: Recommendation Once you receive your package, unscrew and remove the stepper motor (completely), as if you were trying to adjust the belt tension; this shouldn’t void your warranty as you should be able to adjust the belt any time and this is not opening the spindle. Now and without the stepper motor, manually rotate the spindle/chuck; the spindle/chuck should rotate freely, without much effort but not as a skateboard wheel; great if does. Even if you feel a small amount of friction it should be fine as it should be normal on these spindles/chucks. If you have a hard time rotating it (and hear something like a clicking sound) then you should be considering exchange it. Hope this helps. Note: I’m leaving my original comment below in case you were following… Original Comment: Disappointed!...The spindle it's barely turning and seemed to got stuck only after a few times using it. this happened right after my desertcart return window expired, so I contacted the seller for diagrams to see if I could open it and do some clean up or add grease, but they do not have any. The seller suggested to "hammer the inside four claws from the front to the back" but that seems radical and I'm not certain it will not damage completely the spindle. I have seen videos of other 4th axis that they have retainers/big nuts that you unscrew to open the interior, but this model has none; not in the back or in the front, and I have not found a site or video that shows how to open any of these models. Do not recommend. UPDATE 10/9/2019 The seller contacted me again and as there are no schematics available, then it's willing to help me solve the issue in a different way; by sending me a new product for testing and review, and have expedited the shipment. I'll provide new comments an possible update the overall rating once I have tested and reviewed the new product. Review: Significant backlash - Not sure what the other reviewers are talking about there is a ton of backlash. Out of the box the belt tension is far too low. Even after adjusting that, there is way too much backlash to use this for a proper milling set up. Not sure what it’s any good for. ## Features - Specifications of 4th Axis: Center height: 65 mm/2.56 inch; Total height:; 115 mm/4.5 inch; Angle: 0.3°/step ; Reduction ratio: 6:1; Base Material: Aluminum alloy; Size: 210x168x115 mm/8.3x6.6x4.5 inch; Weight: 7.9 KG/17.4 LB; Inner through hole diameter/shaft hollow diameter is 22 mm/0.86 inch; Output shaft diameter:30 mm/1.18 inch - Nema23 Stepper Motor: Phase: 2 Phase; Type: Hybrid; Step Angle: 1.8°; Current: 3.0A; Holding torque: 270oz-in/1.8Nm; Shat diameter: 8mm; 4 Lead Wires: A+ to Red ; A- to Green ; B+ to Yellow ; B- to Blue; Motor Size: 57x57x76 mm - Specifications of MT2 Tailstock: Morse Taper 2 Live Center Movable MT2 Tailstock; Center Height: 65 mm/2.56 inch; Expansion stroke: 45 mm1.77 inch; Stretch distance: 50 mm/1.97 inch; Top tip: Activity type; With Axial locking wrench for tailstock; Exquisite workmanship,Durable,Stable performance,Sturdy and Wear-resistant; Weight: 2.5 KG/5.5 LB - Chuck Type: K12-100 4-Jaw self-centering chuck; Diameter:100mm; Max input torque: 60 N.m; Max Speed: 3500 R/min; External jaw clamping range: 30-80 mm/1.18-3.15 inches.; Internal jaw clamping range: 2-30 mm/0.08-1.18 inches; Internal jaw jamming range: 30-90 mm/1.18-3.54 inches; With four Anti-claw and Wrench - Advantages: Rust proof coating process,stable 4 jaw chuck structure,fine workmanship,solid and practical jaw, excellent process to maximize service life;Application: The fourth axis can be used for three-dimensional processing of cylinders, bends and circles.

Out of the box the belt tension is far too low. Even after adjusting that, there is way too much backlash to use this for a proper milling set up. Not sure what it’s any good for. ### ⭐⭐⭐⭐⭐ Well Made *by K***R on January 8, 2024* 1. The rotary axis and tailstock were nicely packaged. Very well padded with foam. 2. No detectable backlash or lateral slop. This item comes with a 3A motor, which is sufficient but my drivers are 4A so to make sure I do not overload the motor I swapped it out. Another person who purchased this item has a long windy YT video about all the gyrations he put himself through to swap out motors. What he SHOULD have done is read the motor physical specs. My 4A motor fit in with no alterations required. The only challenge I have is mounting the axis to my router bed. I wanted the style that has a bore through the spindle so I can do pass throughs on smaller diameter items. This style has to have the motor mounted to the side of the spindle, so it limits access to the mounting bolt slots. I will probably make a sub plate because I remove this piece of equipment often. This is not a default, just something to be aware of. ## Frequently Bought Together - CNCTOPBAOS K12-100mm CNC Router Milling Machine Rotational Axis A 4th Axis Rotary Table 100mm 4 Jaw Chuck Dividing Head,MT2 65mm Tailstock Reducing Ratio 6:1 for CNC Engraving Machine - STEPPERONLINE High Torque Nema 23 CNC Stepper Motor 114mm 425oz.in/3Nm CNC Mill Lathe Router --- ## 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.sc/products/109600395-cnctopbaos-k12-100mm-cnc-4th-axis-rotary-table-4-jaw](https://www.desertcart.sc/products/109600395-cnctopbaos-k12-100mm-cnc-4th-axis-rotary-table-4-jaw) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-05*
