Starting my spindle journey

[adcostanza (Adam)]

Wanted to start a thread as I swap out by C3D router for a Spindle. I spent a lot of time thinking about wattage (800W, 1.5kW, or 2.2kW) and settled on 800W based on lots of posts in this community and advice I saw from @Julien in particular. I then thought long and hard about air vs water cooled and changed my mind about 99 times before I finally hit the bullet and purchased an air cooled spindle. I have no doubt a water cooled spindle would be quieter but I didn’t really want to deal with the water cooling stuff. I figure I can always change my mind in the future and consider that an additional upgrade.

I ended up purchasing this spindle:

CNC Spindle CNC Motor 110V 0.8KW 800W Air Cooled Spindle Motor 65mm 4 Bearings 24000RPM 400HZ for CNC Router Machine https://a.co/59Q22JA

And this VFD:

Huanyang VFD,Single to 3 Phase,Variable Frequency Drive,1.5kW 2HP 110V/120V Input AC 13A for Motor Speed Control ,HY Series https://a.co/7ajNnXX

I’m hoping that because the VFD is a Huanyang I can follow @Julien post on his setting parameters. If not I’ll reach out with lots of questions

Otherwise I plan to follow some of this post: Water Cooled Spindle Upgrade and Spindle Control

It had a TON of amazing information (thanks @mharper90 !) In particular I do want to add a manual disconnect when I change tools because I like having hands with functioning fingers

Will post more details as I purchase and assemble things. With it being air cooled I imagine it should be a relatively straightforward setup.

I use fusion 360 and recently found a plug-in that supports tool changes in a single file and rapids post processing, so hoping I can put that to great use here!

Do let us know how it goes! That Huanyang VFD model has been used by many users here by now, so chances setup will be straightforward.

I’m still using @fenrus tool to post-process my files to bring rapids back into them, what F360 plug-in is it that you are using ?

Got the spindle running today on my Shapeoko controlled via G Code

Ran into many hurdles along the way but it has been fun. I want to document more of what I did, but just wanted to paste some other threads I found extremely useful in my journey so far (partially for me!):

800w Spindle connector

This particular insulation is rated for 1000V and the shielding is braided making it pretty thick. For those wondering how I got to 16 gauge, here is the math: 800W spindle / 110V x 1.73 = 12.58A - EDIT: I have since learned that this isn’t quite accurate. The correct math is this: 800W spindle / 110V / 0.75 power factor (approx) / 1.732 (3 phase magic because you are using 3 conductors to carry the current, not 2) = 5.6A This is simplified and I am not the person to give more detail. An elec…

Shapeoko 3 Connector Part Numbers

I’ve seen many people and I myself trying to find the correct connectors for the Shapeoko 3. So I’ve compiled a list to have them all in one place. If you find any errors let me know. Also any connectors I may have missed. Please note that there are many part numbers for crimp terminals. Whether Tin or gold, Reel or bag and maybe more. If you can’t find the one listed where you buy your parts, find the crimp terminal series and look for others. On the Molex website a bit under the part numb…

Carbide Motion PCB v3.0b pinout

Some of my notes. I think this is the degree of what I can assist with without being kicked out of the forum. I reckon that C3D support is careful not to give too much advice regarding warranty liability… “Y2” is interconnected in the X, Y, Z connectors, but else unused? “LIMIT_?” signals goes directly to CPU. BitZero and BitSetter has the exact same signals. A tip for an emergency stop if the grounding clip from the BitZero has fallen off during probing - press BitSetter [PCB …

Feed Hold Switch

Thanks Mr mingle for bringing up this subject Multimeter says that the F signal is present on all X, Y, Z sensor input connectors. All signals seems to be mirrored on all connector and the individual wiring from each limit switch are using different pins except the Probe signal marked “P”. This is used both by the BitZero and the BitSetter. This gave me a hint that if I ever, in the last minute, saw that I’ve forgot to attach grounding clip to the mill and probing sequence had s…

VFD Parameters (Huanyang model)

and while I’m here, two wiring snapshots . 220V Hot and Neutral wired to R and T (apparently, it would also work with R and S or S and T too), Earth connected to the VFD’s earth terminal Spindle’s aviation connecteur pin 1 to U, pin 2 to V, pin 3 to W, pin 4 to Earth terminal [VFD_wiring_mains] For control signals, I followed @Luke’s instructions religiously: FOR(ward) to DCM(ground) = forces forward rotation, i.e. the right direction. Shapeoko’s GND to ACM (ground) Shapeoko’s PWM to VI (v…

VFD Parameters (Huanyang model)

This morning I figured I would skim over the parameters out of curiosity, then got carried away and ended up making a note of every single parameter value currently set in my VFD and what it does. In others words, I RTFM. I will leave my notes here in case this could be useful for others with the same VFD model. I highlighted the ones that I think need to be considered for the Shapeoko usecase, feel free to comment if you went through the same exercize and optimized some of these params ! PD000…
