Sorry for the late reply! The spindle motor was the stock motor, it didn't have spindle control unfortunately

Well I have officially started the conversion. Off to a good start here! Still on the fence about re-using the onboard computer. I will be video documenting the process as well on my Instagram page @civil_machine

I noticed you also have the PDB option of the torus pro.

Can you post a couple of photos on how you connected your spindle control to retain all of the PDB function? I just started my centroid conversion today on my torus pro.

Thanks

I'm not sure about the isolator board. I think the outputs from the acorn are already isolated. You need to dig into the manual for the drives to see what it needs for an input. You will have to connect the power draw bar to the VFD. There are safety and control signals. The power draw bar talks to...

SOLVED As suspected, the setting F0.5 was set to "1", changing to -"0"- enabled a working reverse both in MDI and manual adjustment. So what worked on Mach3 as "1" did not work with Acorn which should be set to "0". Now, the Spindle needs tuning to match the ...

If your drives will accept step and direction inputs you are good to go. I fed the speed control directly to the VFD. In addition you will have to use a couple of outputs for spindle forward and reverse. My spindle is the standard one they supply. It's a 2 HP 3 phase 220vac motor. It's driven by a ...

SO- big find here. this is exactly what I need to run these servo drives with the acorn board!!!!!!

You only need the onboard computer to run the acorn. The original novakon break out board will be removed. It will not work with your acorn. The acorn will take over all of it's functions. The acorn has it's own isolated speed control output. You can feed this to the VFD. If I were you I would just...

Just got my servo powered novakon up and running with MachSTD mill- I'm not a fan of this control much at all. Especially after using an acorn on my g0704 build. I'm looking to connect the acorn board thru my db25 parallel port on my novakon BOB. Will I need to run an external computer besides the o...

I have a Novakon torus pro (stepper version) running on an acorn. It was a relatively easy upgrade. The computer Novakon supplied was more than adequate to run the acorn. If you look on the success stories page you can see a photo of how I fit it into the original case. I removed the original mothe...
