This faq is used by support to determine if a wire or motor is damaged, and how to identify each one.
WARNING: DO NOT UNPLUG OR PLUG ANY WIRES IN WHILE THE CONTROLLER IS ON! YOU WILL DAMGAGE YOUR MOTOR DRIVERS AND VOID THE WARRANTY!
You will need a screen and power connected during the tests. You will REMOVE power while switching wires. If you switch wires while the controller is on, you will damage the controller. Therefore, you will be powering up the controller, testing movement via the screen, powering down, swapping wires, powering back up, retesting movement via the screen, powering down, swapping wires, powering back up, rinse and repeat.
Before we start, four notes:
- If you have ANY aftermarket cables, remove them completely and return the machine to it’s original shipped state. We do not support any aftermarket cables and they can damage your machine. Do not contact support if you are not using only the cables that came with the machine.
- Please watch this video showing how to remove the inner tube wires:
https://www.youtube.com/watch?v=YyB5QJ7neVQ - Also, you will need to watch this video showing how to remove the motor from the end of the rail:
https://www.youtube.com/watch?v=wXs3e-eecFk - Some times it can be a simple bad connection. Simply disconnecting and reconnecting the cables can fix it. If not, follow below.
Wiring Diagram:
This is important for anyone who is doing modifications (not supported by Onefinity and done improperly can permanently damage your controller, voiding the warranty) to their wiring like drag chains.
There is a cable cross in all motor wires. On the X and Y wiring sequences, the center curly cable shown here is instead a straight cable contained inside the x and y metal inner tubes.
Operation must include the inner wire. Direct connection to the stepper motor (without the inside wire) will damage your machine and cause the stepper to not operate.
Improper wiring will damage your controller and void your warranty.
Aftermarket cables should not be used and will void your warranty!
Once the above two videos have been watched, follow these steps:
In this case, we’ve started by removing two complete axis wire sets and motors and laid them out to easily identify what they are (for example, these are both the Y1 and Y2 wires and motors.).
- We will start by removing all extension wires. We will put those to the side and see if the machine functions correctly without them. If it does, we know an extension is bad.
- Remove all wires and the motors from our ‘bad’ rail and one known ‘good’ rail. In this FAQ, we will refer to the left side wire chain as wire set one (good, working side), and the right side wire chain as wire set two (bad, non-functioning side).
Example 1:
- In order for an axis to work, you MUST have the inner tube wire (x or y rails) or curly cable (z) installed. There is a wire cross that is included in these wires that must be present for the motor to spin. If it is not installed, the motor will not function as it should. Please see:Onefinity Wiring Diagram
- Unplug the motor from wire set two.
- Unplug the motor from wire set one and plug it into the wire set two. If it rotates, this would indicate the motor we removed is damaged.
- Confirm the motor is defective by plugging in the ‘bad’ motor we disconnected first into wire set one. If it does NOT rotate correctly, this confirms the motor is bad. If it does rotate, we have a wire issue, not a motor issue.
- Confirm all the wires work correctly. We’ll be doing the opposite of what we’ve just done above, checking on the ‘good’ motor from side one. This will narrow down which wire or motor has the issue.
- Check the inner tube or curly cable wires. We will use the good side one cable from the controller to curly cable and attach it to the inner tube wire. If this works, it confirms we have a bad cable from the controller on to the inner tube wire (wire that has mesh shielding) on side two.
- Finally, we’ll swap sides and do the same thing as step 7. We’ll use the bad side two cable from the controller to curly cable and attach it to the inner tube wire. If this works, it confirms we have a bad cable from the controller on to the inner tube wire (wire that has mesh shielding) on side one.
If the above is done and all motors spin correctly, there is an issue with the rail itself. See:
