Hands can be used to split the halves apart. They're friction-fitted together, but not under a lot of pressure. I use them on my 3D printer's two Z axis screws (motors at bottom) that are constantly under pressure from the X carriage and have never separated after 1000 /- hours of use. prints.
I had a problem with mine slipping, and no amount of tightening the screw would make it stay put, so I used a few drops of CA glue to solve the problem.
Yes, it is compatible with Cr10s Pro v2.
For cr10 v3, the thickness is between 5 and 8 millimeters.

Nothing could possibly keep them together if they were to pull apart. After I installed them, my printer began to make a strange noise, as if it were a door hinge in need of lubrication. It took several hours to track down the source. The noise was caused by a piece of hard rubber, or whatever it was, sandwiched between the two metal pieces, which sounded awful, as if my printer was about to fall apart at any moment. The Z lead screw(s) would sway in the same way that the Eiffel Tower sways. Hello, hello, I thought my screw(s) had come loose. br>So I double-checked them and they were accurate. br>Right now, I'm using a solid coupler, and everything seems to be working fine.
On my DIY CNC machine, the flexible couplers milled from a single piece of aluminum tend to shear on both the X and Y axes for some reason. I've tried a variety of brands and suppliers, including the one pictured, and have had the same results. It broke on the simplest of carves after only 6 hours of use, destroying my workpiece. One has to wonder about the mill stock used vs. the mill stock used in the photo and the pictured break, as seen in the photo and the pictured break. who mills them out of that stock However, since switching to this three-piece design, I've been able to run without any problems or mid-race stumbling blocks. Failures in carving! Thanks!.
My package contains two items, one of which is incorrect. br>br> sized, and no matter how tight I tighten it, it doesn't grip. The other, which 'wiggles' and introduces artifacts into my system, appears to be assembled with very poor tolerances. It's not exactly 180 degrees straight; it's closer to 175 degrees.
Axis Screw is a type of axis screw. It works well with Z-. This is a great upgrade over the stock coupler on my Ender 3. The finish is satisfactory, and it appears to be quite durable. My only gripe is that if you apply any kind of tension to the coupler, it will come apart fairly easily, which can be very annoying if you're used to pulling up on the X-bar. To manually raise it, use an axis gantry. That is a design defect specific to my application rather than a manufacturing fault.
If you've been 3D printing for any length of time, your nozzle has most likely collided with the bed. When that happens, these couplers can help reduce some of the damage: instead of continuing to press the nozzle into the bed as 1- If piece couplers are used, the leadscrew will be separated from the motor shaft, further reducing the risk of catastrophic failure. br>br>I haven't noticed any print quality improvements, but on the two printers where these have been installed, I'm less likely to have to replace a bed surface or any part of my extrusion system if the Z endstops or the auto bed levelling probe fail.
These are superior to machined "spring" style shaft couplers in that they can handle offsets (when the shaft is spinning and slightly misaligned) and center the shaft better - The coupler is clamped, not the shaft (normally, set screws push the shaft slightly to one side or the other as they interface with the shaft - Small divets in the shaft where the set screws dug in can also occur as a result of this). br>As well as the price, the quality is excellent!.
I bought a low-cost flexible shaft coupling for a home-built CNC machine and it broke after only two weeks. I replaced the cheaper couplings with these more expensive couplings with a different design, and they work great even when I upgraded my motor from N23 to N34 size, and they're still going strong 6 months later.
In my case, the two shafts were not concentric, causing my 3D printer to wobble horribly. It's possible that the plastic insert and coupling pair were designed to work together. It's not acceptable if you never disassemble these; they will be returned.
