This guide applies to Onefinity Firmware greater than or equal to 1.3.0 or BuildBotics firmware greater than or equal to 1.0.3.

If your Onefinity Buildbotics controller is on an older firmware version, you'll need upgrade to this version or greater or accept limited functionality. Contact us for the “Temporary Addendum” which served as a work around until v1.3.0 was released. Links to the latest version can be found on the Onefinity website. Support | Onefinity USA (onefinitycnc.com).

 

 

Your new Spindle Kit is fully programmed for automatic control but also has a “Manual Override” switch which lets you run your spindle in manual mode via the VFD’s keypad controls.

If you’d like to run your spindle in manual mode, flip the “Manual Override” switch up or “1” to enable VFD Keypad controls. Then use the Run/Stop and Potentiometer dial on the front of your VFD to run your motor.

To Enable Automatic Control:

From within your controller’s user interface, find the 3-Bar Menu -> Tool screen and change the

tool-type=”PwnCNC VFD” or “EM60”.

And confirm / enter the following values:

Label	Value	Description
tool-reversed	[unchecked]	If the tool is turning in the wrong direction, this checkbox will fix it.
max-spin	24000	Maximum rpms of the motor
min-spin	0	Minimum rpms of the motor
bus-id	1
baud	9600
parity	None

 

If your control cable has been plugged in, then you’re good to go. In the Modbus Status section, “connection” should show OK letting you know it’s properly communicating.

 

 

95% of common problems can be resolved by performing the following steps checking your connection after each step:

1. Ensure your cables are connected both at the breakout board and the VFD and it is on.

2. Ensure that your VFD Manual Override Switch is in the Automatic position.

3. Try re-flashing your firmware even if it is the current version. 

4. Validate the VFD Settings. To do this press “mode” on the keypad. P0.0.00 should be blinking. Use the double arrow button to navigate to the next segment, and the up and down arrow to change the parameter. Once you’re on the correct one, press enter button, and again up or down to change the selection, and enter to accept it: (There is flow chart of how to navigate here)

• P0.0.03 should be 2
• P0.0.04 should be 9

5. Try removing the standoffs at the connection of the receiving end of the DB25 connector. 

6. If you're showing "Timed Out", swap the cables in the breakout board. The wiring is sometimes backwards in the controller, and if you switch the cables in pin 13 & pin 14 it will make the proper connection. If this does not resolve the connection problem, swap them back.

If your spindle takes an excessively long time to spin down, please see this notice.
