I don't know the exact specifics of the wiring but considering the quill has "auto-feed", I would suspect that they used all four drive axes of the base Oak. I'm also assuming that they used one of the auxiliary encoder ports for a spindle encoder. Whether or not they used the WMPG or wired MPG or ...

One easy way to use the default Umbrella ATC PLC program is to install CNC12 and select the Oak/ALLIN1DC option in the installer. This will install the version that does not use the Wizard and you will be given the option to install the Hickory Mill Umbrella ATC PLC program.


Without the Wizard ...

Hello, and welcome to the forums.

First and foremost, you have the Mechatrolink variant of the drives. Those will not work with Acorn or our other controllers. To reuse the motors, you would need to swap them out for analog/pulse input models. Your drives are SGDV-1R9D 11 A but you need SGDV-1R9D ...

Those are both pretty standard VFDs and either should work for running a 400Hz router spindle. They both have configurable inputs and outputs so you'd need to read the manual to figure out how to assign the functions. This being a router, you probably do not need to worry about wiring for reverse ...

Hello,

I have seen this and similar issues before but I would not expect to see them on current production KP-3s.

From what you've said, it will be stuck tripped from the kinematic seat not settling correctly. When the LED is dim, the kinematic seat settled but with high resistance.

Staying ...

Hello, sorry for the delay.

We've managed to reproduce it internally and are actively working on fixing this issue and several other fixes and improvements for USBBOB.

Wait a minute... Sorry about that, I made a mistake here.

You do not need to connect DCM to the COM on H9. It is fine and probably recommended to leave those common (logic grounds) separated. S15008 shows no connection between COM/Acorn power supply V- to DCM.


The rationale here is that the VFD ...

Aside from the incorrect labeling in the table, the main issue is that DCM needs to connect to the COM on Acorn H9.

Other than that, it should be good.

Does it get hot while it is at zero speed?

Digital GND (DCM on the VFD headers) goes to the return/common of the Acorn's power supply or separate PLC power supply. It is also labeled COM on Acorn H9. (If you have multiple power supplies i.e. one to power the Acorn and another to power the PLC inputs/outputs, then their common terminals need ...
