Mark start point, do a toolpath and when it ends and goes back to Home, it was about 12 mm off on the X axis. I configured everything according to manuals and it was acting like it was losing steps.

These are wired to the 4 Nema 23 Stepper motor on a CNC build similar to the Workbee. The above also has wiring for a spindle control, see the right-side bottom 4 wires on the NVEM.I bought the NVUM v2 Control board in a pakcgae deal with the TB6660 Stepper drivers.

Note fans on the right to assist in cooling the TB6600 and prominent location the Emergency Stop Switch. See below for an example of how to layout a controller case. If the power is daisy chained then, if all drivers are active, the current on the wire from the Power Supply to the first Driver will carry 4x the current and means the last Driver in the chain will be under powered – DO NOT DAISY CHAIN POWER TO THE DRIVERS.

This makes for cleaner and better connections.Īlso note that each TB6600 has a pair of power cables running from the Power Supply to the Driver and are NOT daisy chained, that is, NOT from Power Supply to X Axis Driver, then from X Axis Driver to Y Axis Driver and so forth. Note the crimp connectors on the power and stepper cables. The Controller, TB6600 Drivers, Power Supply, Stepper Motors, Switches and etc are connected as per the diagram below: For more details of each connection refer to the Novusun manual. NOTE: It is critical to use the correctly rated/sized wire for all connections.

Note : Any Mains power connections must be installed by a Licensed electrician or suitability qualified person.Įrrors and omissions excepted Introduction FAILURE TO DO SO WILL VOID ANY AND ALL WARRANTIES.īefore starting please read though all the instructions.
