A few questions around my LR4

LowRider CNC Troubleshooting
1

Hello to everyone

I just finished mounting my Lowrider v4!!! I yet don’t own a makita router so I made a mount for my cheap 500w chinese router. I use Dreanique 2 flute down cut router bit (WD2F D4 L25) and I’m experiencing a lot high pitch vibration at 600-800 mm/min 11000tr/min, 2mm deeps, hard wood (ash)

I don’t know how to improve it,

-my first guess is to change the router for a 700w makita the thing is I like to use 3.175mm bit and apart from the v1 shop I can’t find any collet for that dimension. Shipping to europe is insanely expensive and there is no way I pay 100$ a collet…

-second guess is to change the bit for a single flute up cut bit from dreanique (SP1FC) so it sends the chip away instead of pushing them down…

-Third guess is something I don’t know about the machine that needs tuning but what? belts are quite tight, X carriage as well…

Any ideas?

Here are a few pics of the beast:

I made a video as well but for some reason I can’t link it…

It’s roughly 40€ total, I bought it a few years back. That should be doable and is really needed. Swallow that pill now and you are good to go.

Or buy an AMB with ER16 collets. If you can wait a bit, you can buy mine, I am going to upgrade to an ATC spindle. :sweat_smile:

Regarding the endmill: I only use upcut. Downcut is really not that great except you know why you need it. :sweat_smile:

Yeah not sure where I will go withe the spindle choice, Makita would be usefull in my shop beside the lr4 use but I really like the ER collets option that my tiny spindle offers. And no it’s not 40 total it’s more like 100 shippings are already 40€ plus collet plus duty… I will try a upcut bit I have for aluminium tomorow to see if I still have this problem

Yeah, a proper end mill has reduce most of the high pitch noise from the router.
