I have just completed the install of a 800w 110v spindle to my Shapeoko 3, but I’m concerned that the spindle is too noisy and would like your opinion, please.
Attached is a video clip of my newly install Spindle which seem to be very noisy over 8000RPMS. The spindle video is running between 2000-24000. Does this sound normal with the high pitch over 8000 RPMS?
Also, if you’re controlling through your boards PWM signal, here’s macro for a daily warmup.
Ongoing, warm up the spindle for “15-20 min” each day before use. I’d also do this if I let is sit idle for multiple hours, especially when my garage is cold in the winter. I created a 15 min macro in cncjs to run while I’m setting up other things to prepare for jobs.
Gosh yeah - that sounds like a spindle issue. Maybe a bearing issue or an electrical noise issue. This is my 800W air-cooled (which are typically a little louder) spindle running at 24K after warmup. https://photos.app.goo.gl/nnDTZkNLgkyCzp2K8
I checked with Decibel X app on my phone, 62db at 3 feet from the spindle. The 70db max in the screen shot was right at the spindle.
You could check the wiring connection under the end cap. I haven’t gone beyond that with disassembly . Hope the spindle company will help you with a warranty claim.
Looking at the video, it sounds like the low pitch noise (behind the horrible high pitch) is the regular sound it should make, and that’s quite constant and regular so the bearings are probably not completely toast. It’s “something” rubbing somewhere in there…Does the spindle make any squeaky noise when you rotate the shaft manually (and slowly ?). Anyway there is probably not much you can do except return it.
