To calculate this, there is a great excel sheet found here. If you use mm, that means 1 mm, and for inches, that means 1in. The “steps per” tells us, how many steps should a stepper make to move it a given unit. There are a couple of different options we will configure. Select the axis you want to configure by pressing on the axis button. To get to the motor configuration window, click on the ✼onfig« menu the then select »Motor tuning«. On first restart, Mach3 will ask you to select the motion controller you want to use – select PoKeys in the list. We will assume that you followed the instructions in the previous tutorial and have added the PoKeys device to Mach3. Now, we will configure Mach3 for operation with PoKeys devices. Once connected, you can use the same 10-pin IDC cables with connectors as with PoKeys57CNC above. Connecting PoStep25-32 with PoKeys57U/E with PoExtBusOC16-CNC external pulse generatorįollow the instructions in the PoExtBusOC16-CNC user manual on connecting it to the PoKeys57U or PoKeys57E device. Remember to never apply power to the driver without connecting the stepper motor first. Now you can power up the stepper motor driver since it has the motor connected. As shown in the documentation of both products, we connect them with the help of the following pictures: Next we will connect the driver to the PoKeys57U controller. ![]() SETUP SERIAL MODBUS MACH3 GENERATORConnecting PoStep25-32 with PoKeys57U/E with internal pulse generator If needed, the cable sets are provided in our store ( ). SETUP SERIAL MODBUS MACH3 DRIVERSConnecting PoStep25-32 with PoKeys57CNCĬonnecting PoStep25-32 drivers with PoKeys57CNC is easy – use the 10-pin IDC connectors with flat cables to connect the stepper driver to one of the first four motor output connectors. And if you would like to know more about how stepper motors work, you can start reading here. If you have different stepper motor and/or driver you should check their documentation to determine the correct connections. The last column will tell you, which wires to connect together and which ones go to the driver. ![]() We connect them to the driver with the help of this table: Mach3 setup tutorial – table More informations about stepper motor driver: stepper motor driver – complete explanation.Īs you can see from the datasheet the stepper motor has 8 wires, which we have to connect. In this example we will use SY60STH86-3008 stepper motor and PoStep25-32 stepper motor driver. The stepper motors usually have 4, 6 or 8 wires. This first step is chosen first intentionally so that you can’t power up the stepper motor driver, without the motor connected by accident. Connecting everything togetherįirst you must connect the stepper motors to the drivers. You can find the previous Mach3 setup tutorial here. SETUP SERIAL MODBUS MACH3 HOW TOThis Mach3 setup tutorial will show you how to connect everything together and how to configure the PoKeys plugin so you can move your CNC. ![]()
