To clarify here, the expectation is that if there is a problem and support is requested, the 3rd party add-on will be removed, the default configuration restored if necessary, and support will proceed from that known state which we understand/have experience with — we can’t support things which we have never seen/used.

Well that wouldn’t be entirely truthful, you see you void the entire warranty when you use a non compatible spindle and forgo your entire support metric with the exception of this forum is explicitly what I have in writing via email
We’ve seen other customers use it, but plugging in other, untested electronics does void the warranty: Carbide 3D Machine Warranty
You’d also be on your own for wiring since we don’t know how they set up their system, so you’d have to ask them.
Edit: My guess is they’re working on a way of tracking and connecting those that purchase the 80mm mount without their spindle (If they’re even going to be available at the same time) and make it far easier to void the warranty without a barrage of questions and hoping the customer is truthful.
I asked about 80mm as well and they said no ETA, so i’ve been looking at alternatives. I intend to upgrade to a 2.2kw 80m spindle as soon as i can figure it out.

Thank you for your insight! I was aware of the warranty issue with this way of doing things i just cant help but want to take this great machine carbide 3d has created and get it closer to its full potential! Not to mention sort of future proof it…

You will want to add some additional electronics to allow you to trigger the VFD FWD pin when there is a PWM signal active. Below is a example circuit to do just this. The op amp used as a comparator in this circuit is a LM324, the transistor is a 2N2222.
If you do not want to pull the PWM signal from the SO5’s ICSP port, you will need to add some electronics to do signal conditioning on the PWM signal. Below is a example from woodworm. You could also just add a low pass filter before it hits the VFD as well.
I hope this helps.

Like i said i have spent quite a while reading about other peoples experiences and i cant help but be inspired by their accomplishments with their machine set ups.
There is an added sense of accomplishment with this way of doing things as well as the acquired knowledge of the machine workings and the skilled to communicate with it.
Would you mind explaining the use of the ICSP port instead of the provided “spindle” port on the controller?
The SO5 circuitry does not play nice with VFD’s without additional signal conditioning. C3D does the signal conditioning inside of their VFD box. By grabbing the PWM signal from the ICSP port you are getting the signal before it has been messed with by the SO5 circuity, eliminating the need for additional signal conditioning.
Here is a trace of the PWM signal from the SO5’s spindle port:

Ah i see… well this helps a lot! The ICSP signal will still allow the user to control speed as well as turning the vfd on and off? What type of connector does this require?
Yes, it’s the same signal just grabbed before it gets mangled by R209 and C140 on the SO5 PCB.
I just used dupont connectors in the picture shown above. You can purchase an adapter from dupont to GX12 from PWNCNC that can be mounted to the front panel of the controller which is what I am currently using.
If using the adapter then you can purchase a GX12 cable to go from the SO5 to the VFD. The adapter and cable can also be purchased as a bundle.
You can always source your own connectors and cable as well.

Thanks for all the helpful tips! I really appreciate it!
Which method are you using to power on your water pump and dust collection? Suggested pump and parts?
I have easy access to my chiller and dust collection power buttons, so I just manually start and stop them. If I were to have my dust collection automatically start and stop with the spindle, I would use either the FM1 output to turn on a IOT power strip or the T1 relay output with a added relay and flyback diode.

Thanks for the great advice! Seems like this Warthog controller has quite a few capabilities above and beyond what the cnc is utilizing…
Do you have a good suggestion for a relay that will work directly with a single phase 240v, 10amp dust collector?
Does your dust collector actually pull 10A? If it pulls less, then the relay I previously posted would work fine. If it is close to 10A then you will likely want a bigger relay.
Here is a larger 25A relay that would work if using the T1 relay function of the EM60 or EM61 VFD.:

You would need a bigger flyback diode if using the bigger relay above as it energizes at 240V instead of 24VDC:

It is not the warthog controller adding the functionality but rather the VFD. EM60 or EM61 in these examples.

Ok so I’ve gotten everything ready to wire the dupont connector onto the icsp port on the warthog board… which of the pins is the signal and which is the ground?
It is a standard 6 pin ICSP port. In the previous picture I posted the white wire is ground and the grey wire is MOSI(PWM signal)

Ok thanks for the diagram! I dont think i have the right connectors though… can you by chance post a link to exactly what i need to make the connection?
These are what i currently have:
Just wanted to say thanks for all of your help with this! I am up and running with the 2.2kw water cooled spindle/vfd. Everything is working great. I really appreciate your help!
