Replacing Chinese JP-382C board with genuine PlanetCNC MK3DRV controller
1. Take your control box and remove all screws of the top cover: Now remove top cover of control box: 2. Locate JP-382C board and disconnect connectors of cable sets for X, Y and Z axis motor outputs, power supply and E-Stop switch. They should not be hard to find: 3. Remove JP-382C board from […]
Plasma CNC and floating Z axis with PlanetCNC
Sometimes we need to modify our CNC machine in order to achieve our machining goals as quickly and as efficiently as possible. CNC machines such as plasma, plotter cutters, lasers need mechanism that helps with measuring of material surface. Good example of such modification is Floating Z axis. The concept is pretty straight forward: Z axis has […]
Spindle synchronisation with PlanetCNC TNG
CNC lathe thread cutting requires spindle RPM’s to be synchronised with machines linear movement, we call this spindle synchronisation. To achieve this, controller needs to read feedback signal from machines spindle to obtain information at which RPM spindle rotates. For this purpose we can use incremental (with quadrature A and B signals ) encoder or […]
Using Adapter for 16 pin header with PlanetCNC controllers
If you need to connect your external electrical equipment such as sensors, switches, buttons, encoders with controller using single wires, you can use adapter for 16pin header. Adapter pinout when connected to CTRL header of Mk3 controller: Adapter pinout when connected to JOG header of Mk3 controller: Adapter pinout when connected to LIMIT header of […]
Using Adapter for 10 pin header with PlanetCNC controllers
If you need to connect your external electrical equipment such as sensors, switches, buttons, encoders with controller using single wires, you can use adapter for 10pin header. Adapter pinout when connected to AUX header of Mk3 controller: Adapter pinout when connected to AXIS header of Mk3 controller: Adapter pinout when connected to INPUT header of […]
Using output board for spindle control
In this tutorial we will explain how to use output board with VFD and spindle. We will describe how to set VFD* parameters and how to connect output board with VFD control inputs. We are aware that many users use different VFD’s but no worries, the work flow in a sense should be the same. […]
Using optocoupler adapter board with PlanetCNC controller
Bottom wiring diagrams demonstrate various uses of adapter with optocoupler: Optoisolated axis output: Optoisolated limit switch inputs: Using PNP proximity switches with optocoupler adapter: With 12V power supply: With 24V power supply:
Using SD card adapter with PlanetCNC controllers
Connect SD card adapter with the Planet-CNC controller: Mk3 and Mk3/4 controller: SD card adapter is connected to Mk3 and Mk3/4 controller with 10pin flat cable trough SD&I2C connector. Mk2 controller: SD card adapter is connected to Mk2 controller with 10pin flat cable trough EXT connector. Export your toolpath to Raw file format in […]
Using output board with PlanetCNC controllers
Output board is used for control of external equipment such as VFDs, coolant systems, vacuum pumps etc. It requires 12V power supply connected to a terminal labeled 12V (be careful with the polarity). Output board has 3 relays and 0-10V output. Relays can be used as NO (normally open) or NC (normally closed). Output board can be […]
Using EggBot with PlanetCNC controller and Toslink
In spirit of Easter holidays(with a slight delay) we decided to wipe the dust from our EggBot and see if still works. We thought that it would be perfect if we use Toslink devices to demonstrate how both, Mk3 controller and Toslink work perfectly hand in hand. For better understanding of Toslink please follow link […]
