Feeds & Speeds for Carbide VFD Spindle

Just got my VFD spindle installed - already super impressed at how quiet it is on tests!

Now I’d like to start working on some cuts, but I don’t know how to go about testing to see how much “better” the cuts can be, or even what a baseline would be that I could use it for. In the past, I’ve just used the Shapeoko parameters in Carbide Create. Is there any way that I could use the HDM parameters for the bits as even a starting point? I work solely with wood right now, mainly hardwoods like maple and birch.

I found that when I tried to use G-Wizard, my parameters were much higher than the recommended (and my cuts went disastrously), and I have no idea what I was doing wrong. I guess I’m just looking for a place to start? Thanks~

I just installed mine last night as well. I was wondering speeds and feeds as well. I do have a question for ya. When your VFD is just sitting is it reading 00 or another number? Mine just sits at 178.4 unless I have it running.

Glad I’m not the only one! Mine sits at 0…Is yours actually spinning? If it’s reading a number, shouldn’t that mean it’s spinning even if it’s very slow?

Thats what i thought… but no, it’s not spinning. just flashing it. I emailed carbide about it last night, because mine also didn’t come with a power plug, but i haven’t heard back yet.

We don’t have a set of parameters for the HDM that fit this criteria, even then they wouldn’t be correct for the spindle kit.

Typically the starting point would be your existing settings, then increasing feeds/speed and DOC based on material and end mill. Carbide create has a starting point in it for our tool library’s, other tool providers usually provide guides.

Press the >> button on the VFD.


Yeah, figured that one out. Thank you for the response.
