Hello, I am thinking of buying this spindle and VFD on Amazon for my LR4. I have the jackpot controller. Will this spindle & VFD work with this machine? I used a harbor freight router on my last machine and it’s just so loud. Thanks in advance.
The 65mm diameter its ok. You should read what vdf comes with that kit(model) and look it up into the fluidnc wiki spindle section and see if it is supported. I would recommend a kit with the HY type
That will save you some headaches 
.
You will need also an Rs485 module for your Jackpot

An 800w spindle will work for you. Im pretty sure you wont beed the full 1.5kw
Dang well I guess we’ll see. Can you please link the fluidnc wiki spindle section that you speak of? Also, the spindle and vfd are past the return date so I hope it works lol.
1.5kw with 110V is not too much, so I’d take it. I run a 1400W with 230V…
Also I’d have taken a water-cooled spindle if you found the router too loud, though the loudest sound will be the cutting sound anyway. 
You’ll need to look at this section. This isn’t really a V1E thing, you’re moving over into FluidNC.
But, if your VFD supports RS485 communication, you’ll need the expansion board here:
I found RS485 to be fairly easy to figure out. But it did take a bit of troubleshooting the communications to get it working the way I wanted.
If your spindle/VFD doesn’t support RS485, then you’ll need to look at the other sections and translate to the Jackpot.
Keep in mind, the stock configuration for LR4 is a trim router. So several of us are happy to try and help with the spindle, but it’s an advanced modification with many variations.
Yikes, kind of sounds quite complicated. These communication remedies and modifications you speak of… are these hardware or software/code modifications?
The fact you found that complicated means you aren’t ready to use it (i mean a spindle with vfd) I think you would find out that running the recomended palm router will suit your needs more. I would opt for the carbide router (it comes with 1/8”+1/4" er11 collets out of the box. That should get you going pretty easy
I run my lr4 with it + a relay module to handle the On/off function
If you find yourself needing the speed control Link (select 110/220v and the HY option -that will save you some headaches-
Thats an 800w spindle with a plug &play vfd for fluidnc
Note: you will need the rs485 module for the jackpot controller. 8mm tpu hoses, water pump.
The config for the jackpot its pretty easy, once you have set up the vfd parameters the config example from the fluidnc wiki works. I would advice to start with the 60usd carbide er11 router
I re-read your initial post and the router you’re using is to too loud? I have an air cooled spindle and its much quieter than the trim router, but between the dust collection, and the actual cutting noise, its probably a 10-20% drop in overall intensity while I’m working.
If you want to further reduce sound, you’d probably need the water cooled version of the spindle. Either version would require a control cable and a power cable for the spindle. Then you’ll need to set up the water cooling system and ensure the additional tubing doesn’t create drag on the core. So creating the needed core attachments isn’t trivial.
Then you’d need the RS485 module. If you have an HY VFD, there are instructions, but some setups may work better with the control cable grounded but may have trouble if you ground it incorrectly. (You can/could ground the VFD end, the Jackpot end, or both ends. My understanding is that it depends on how you wire your common ground, but I don’t know enough to fully comprehend the principles.) Its best to follow the instructions for your VFD.
All this is to say its more than a simple question about that particular spindle.
I appreciate the feedback. I don’t want to make things complicated if there is a simple way. I begged Amazon to let me return the spindle/VFD that I bought and so I am going with the HY Huanyang water cooled. Why not go with the 2.2KW? I understand the spindle sticks out further from the X-gantry since it’s 80mm diameter which maybe is testing the rigidity of this machine. I have seen others use a 1.5KW spindle, such as Tom Myers, I think on an LR3. Both are 80mm. Perhaps a 1.5kw will work fine. Just don’t want to get a 0.8kw as I don’t want to be lacking power.
Yes my HF trim router was screaming loud. I supposed with the noise of the vac and actually cutting the spindle won’t reduce the sound that much. I have the RS485 ordered, and I am planning on getting the HY spindle. any reason not to go with a 1.5kw or a 2.2kw? I know they’re 80mm but I saw Tom Myers post a video of his LR3 with a 1.5kw spindle and it seems to be working great. I don’t want to get a .8kw spindle and be underpowered.
Maybe HF routers are particularly bad but what speed setting do you run it at?
Honestly I don’t remember. Haven’t run a cnc in about a year.
The reason I ask is my makita at full speed is incredibly loud.
But at speed 2 to 3 which is where it is when using it on the lowrider it’s comfortably quiet - quieter than the shop vac.
Weight! Spindle diameter (80mm is a no go)
If you cant return your spindle kit and already ordered the module: get the HY type VFD. The inverter alone will run for less than 120
you want this one not not this (fc01 can work, but is a hassle)
My carbide router the most i have asked is 2.5 on the dial cutting stacked acm sheets and relative fast feeds
I have an 1.5kw spindle in another cnc and I found myself not using all the available power because i do t want to kill my bits too soon and i want good finish on all my cuts, just compressed air to clean debris/anything the vac didn’t pick up.
Good feeds&speeds are your friend in the cnc world. I would say you wont need a full 0.8kw spindle (at full speed also) 16krpm/24krpm is nutz
It all depends on how strong your setup is, work hold down (vibrations matters) how clean/exact you want your cuts, materials used etc. my settings may not work for you as/is etc.
Also - that weight is pushed a few precious mm out further from the core, which I think just compounds the weight issue. The center is 7.5 mm greater from the diameter of the spindle body, and any modifications to bolster the mount just add more distance. This can get really out of spec fast.
I have a 1.5k and I don’t use the full power, but I do like the overhead. I think it runs quieter since I’m generally only running about 1/3 - 1/2 of its speed.
I’m completely unqualified to make this last statement, so maybe someone who knows can correct me, but I have the 110v US version of my spindle. I think if you are in a 220v region you’ll have more efficient power at the endmill. (I do have 220v for my table saw and I notice a difference when I’ve had to run it at 110v on hardwood.)
Yes.
Yes, 220v can get away with thinner wires. If he has the availability, 220v should be better
