Review: Yes, it is loud, but no louder than my wood router. - First thing I did was measure the runout. I put the motor in a vise and placed a dial indicator on the side of the collet holder (without the collet cap). Rotating by hand, the total runout is .001". This is very good. The collet holder is glued onto the motor shaft. I suspect this is because they tweak the thing until it's true. I'll bet this is why they give you a holder with the motor. You are purchasing a system. I would recommend that you never remove the holder because it'll never go back on straight. Went to install it on my cheapo 3018 and it wouldn't fit. There is a metal band on the motor, presumably so it will fit larger machines. The band simply snaps off, which allowed the motor to fit into the Z-axis bracket just fine. The diameter of the motor, without the band, is 1.65" I read all the reviews about ramping up the motor, but just for fun, I simply turned it on at full speed with the Candle interface. The motor came on without any issues. However, just for good measure, I will put the ramp-up code into the header section of the gcode generator so it's always there for all NC program files. The motor is very loud, but not because it's unbalanced or out of round. It runs at 20K RPM, so I would expect it to be loud. It isn't any louder than my Craftsman wood router. I was hesitant to purchase this motor, but since desertcart has a decent return policy, I decided to risk it. So far, I'm pleased.
Review: Very good 775 replacement motor. My 3018 can actually now cut! - Although I haven't had this for long, I felt compelled to write this. I have a TT 3018. The first few cuts I made in wood were disastrous. Basically, the ER11 coupler that came with it keep moving. I tried fixing it but found out that the motor shaft was 4.89mm and the coupler hole was 5.25mm. Horrible vibration and it eventually fell out while cutting. I decided to buy this item since it advertised 20000 RPM and folks had good like with it's balance. The motor installed in the 3018 without an issue. Turning it on, without any cutting proved to be much more quite that the stock motor/coupler, indicating good balance. I also have a handheld RPM meter, bought here on desertcart: https://www.desertcart.com/dp/B07Q6M95PF Which I used to verify max RPM. It got 19800 no problem. I was able to also see 20700 but good enough. I also tested a few different motor speed settings, which showed that my cheap controller can get different speeds out of this motor. $30 set to 20000 Hope this long table helps Setting: RPM S100M3 3200 S200M3 8000 S300M3 12000 S400M3 14600 S500M3 16000 S600M3 17700 S700M3 18500 S800M3 18500 S900M3 19700 This speed stuff is not exact but I'm happy to see that I can set different speeds if needed. Original motor supported 8000RPM max. I also did a 90mm x 100mm x 12m (depth) carving using 1/8 end mill and a v-bit at max RPM. Took about 3 hours. This motor cut through just fine. No over heating, not excess vibration, no stalls. For $25, throw out the original motor and get this.

## Questions & Answers

**Q: How and where do you enter codes they recommend. i adjusted the speeds on my 3018 in easel but now it is slowing down again. wonder if i need a power**
A: WHEN YOU ARE IN CANDLE AND YOU OPEN YOUR FILE YOU MADE WITH EASEL, LOOK AT THE G-CODE YOU WILL SEE AN S CODE THAT IS YOUR SPINDLE START FOLLOWED BY THE RPM.  CHANGE THE NUMBER TO THE DESIRED RPM

**Q: Buenos dias por que el motor al conectar los 24 voltios solo gira una vuelta y se para cada momento**
A: Hola, ya lo conectastes a 12v. respetando la poralidad?. Prueba polaridad y con 12v CC. Suerte!

**Q: If i use the new updated power supply from saintsmart (24vdc/4a), is ramp up using gcode still needed as in instructions?**
A: The new upgraded power supply can work with this spindle perfectly.

**Q: I see the code for a slow start, do you have to add it to every file or can it be set globally in UGS one time and it resides there permanently?**
A: You would want to add it in to your post processor in whatever cam software your using if you want it to be baked into your gcode every program. Ugs just reads your NC file and sends it to the machine

### ⭐⭐⭐⭐ Great performance as long as you get one that is balanced
*by A***R on March 1, 2022*

Spindle gives excellent performance compared to the stock 10k. Has alot more power and the extra rpm allows you to run higher feeds and speeds. Alot less likely to chatter with the small bits hogging out materials. My first test was on 1/2" birch plywood running 20k rpm 30in/min feed 9in/min plunge and 0.028" depth per pass and it flew through like a hot knife through butter. That being said this is my second spindle the first one was so out of balance it was super loud and shook the machine like crazy compared to the stock spindle which was nearly silent. I put in for an exchange and the second spindle I received runs perfect just like the 10k but much better performance. Don't settle for one that is loud and shakes they aren't supposed to.
