-==== CNC mill controller setup ====  +{{tool:metal_cnc:jaxencncmill.jpeg?300|Jaxen CNC Milling Machine}}
- +
-All the controller hardware is located in an electrical panel on the wall behind the mill. +
- +
-{{tool:metal_cnc:jaxencncmillcontrollerpanel.jpeg?300|NDR-480-48}} +
- +
----- +
- +
-=== 1. Power Supplies ===  +
-There are four Mean Well power supplies: +
-  * NDR-480-48 (x2): Provide 48V, 10A DC to the stepper/servo drivers (blue modules marked Motor Z/A and Motor X/Y). +
-    *  These deliver the high-power DC that actually runs the motors. +
-  * MDR-60-24: Provides 24V DC for control electronics (like relays, sensors, and logic boards). +
-  * MDR-60-5: Provides 5V DC for logic-level components (controller board, encoders, or optoisolators). +
- +
-**Hookup**: +
-  * AC mains (100–240V) enters at the bottom (L/N/Earth). +
-  * DC outputs (+V and –V) run to the motor drivers and controller boards. +
- +
-{{tool:metal_cnc:jaxencncmillcontrollerpower1.jpeg?300|NDR-480-48}} +
-{{tool:metal_cnc:jaxencncmillcontrollerpower2.jpeg?200| MDR-60-24 and MDR-60-5}} +
- +
----- +
- +
-=== 2. Motor Drivers ===  +
-The blue modules marked X, Y, A, and black module Z, are stepper/servo motor drivers. +
-  * Function: Convert low-level step/direction/enable signals from the controller into high-power pulses for the motors. +
-  * Each axis has its own driver. +
-  * Wiring: +
-    *  Signal side (green connectors): Receives Step (Red), Dir (White), Ena (Green) from the motion controller. +
-    *  Power side: Fed by 48V from the NDR-480 supplies. +
-    *  Motor outputs: Four heavy wires going to each motor coil. +
-    *  Rotary encoder inputs: see Motor (XY) Rotary Encoder Pinouts below  +

-  * A+ = Red +
-  * A- = Green +
-  * B+ = Yellow +
-  * B- = Blue +
- +
-This means it’s a 2-phase, bipolar stepper. +

-{{tool:metal_cnc:typicalwiringdiagram.png?600| Typical Wiring Diagram}} +
- +
-This is a standard quadrature encoder setup (channels A and B), giving the controller both position and direction feedback. +
- +
-** XY Typical Specifications (based on 57HSE2N series)** +
-While exact numbers vary slightly by supplier, the 57HSE2N-D25 generally matches: +
- +
-^ Attribute          ^ Value (typical)                                        ^ +
-| Frame Size         | NEMA 23 (57 mm)                                        | +
-| Step Angle         | 1.8° (200 steps/rev)                                   | +
-| Holding Torque     | ~2.0–2.5 Nm (280–350 oz-in)                            | +
-| Rated Current      | ~4.0–5.0 A/phase                                       | +
-| Resistance         | ~0.5–0.8 Ω/phase                                       | +
-| Inductance         | ~2.5–4.0 mH                                            | +
-| Encoder Resolution | 1000–2500 PPR (typical, quadrature)                    | +
-| Voltage Drive      | 48 V DC (as supplied by your Mean Well NDR-480-48 PSU) | +
- +
-  * XY axis are closed-loop stepper motors—sometimes marketed as servo-stepper hybrids—which combine the simplicity of stepper drive with the position assurance of encoder feedback. +
- +
-**Function in Your CNC (Jaxen)** +
-  * X Axis Motor: Moves the table left/right (long axis). +
-  * Y Axis Motor: Moves the table front/back (short axis). +
-  * Both motors receive step/dir signals from the CNCdrive AXBB-E motion controller via the blue motor drivers you showed earlier. +
- +
-The encoders feed back position to the drivers, enabling stall detection and correction, preventing lost steps. +
- +
-**Z Axis Motor not documented** +
- +
-**Summary:** +
-The 57HSE2N-D25 motors on your Grizzly/Jaxen CNC are NEMA 23 closed-loop stepper motors with encoders. They provide about 2–2.5 Nm torque, run at ~4–5 A/phase, and are driven by your 48 V Mean Well PSU through dedicated stepper drivers. Their integrated encoders make the system far more reliable than open-loop steppers. +

-=== 7. Limit Switches and RJ-11 Breakout Board === +
- +
-**Limit Switch Configuration** +
- +
-Jaxen CNC uses **one limit switch per axis** (X, Y, Z). Each switch is mounted at the **home end of travel** for its axis. +
-UCCNC manages the opposite end of travel via **soft limits**. If any limit switch is triggered during machining, motion stops immediately on all axes. +
- +
-**Physical Layout** +
- +
-  * **X Axis** → Limit switch at the X− end (left side when facing the machine).   +
-  * **Y Axis** → Limit switch at the Y− end (front of the table).   +
-  * **Z Axis** → Limit switch at the Z+ end (top of spindle travel).   +
- +
-Each switch is wired into the controller as both a **homing switch** and a **limit switch**. +
- +
-**Function in UCCNC** +
- +
-  * During homing, the axis moves toward the limit switch until it triggers, then backs off to establish machine zero.   +
-  * During normal operation, the same switch acts as a hardware limit in that direction.   +
-  * The opposite end of travel is protected using **software soft limits**, defined in UCCNC machine setup.   +
-  +
-{{tool:metal_cnc:jaxenlimitswitches_x.jpeg?300| X Minus Limit Switch}} +
-{{tool:metal_cnc:jaxenlimitswitches_y.jpeg?300| Y Minus Limit Switch}} +
-{{tool:metal_cnc:jaxenlimitswitches_z.jpeg?200| Z Minus Limit Switch}} +
- +
-These limit switches are connected through a dedicated **Creltek RJ-11 Sensor Breakout Board v2.1** for safety and homing. This board consolidates up to 8 limit switch inputs into RJ-11 connectors, making wiring cleaner and reducing electrical noise from motors and power electronics. +
- +
-  * Each axis (X, Y, Z) has independent limit switches routed through the breakout board.   +
-  * Output signals can be **wire-OR’d**, allowing multiple switches per axis if needed.   +
-  * The breakout board is wired into the **AXBB-E motion controller**. +
-  * Designed for **reliability in CNC environments** with high electrical interference.   +

-=== 12. PC & UCCNC Software ===  +
-  * [[https://www.cncdrive.com/UCCNC.html|UCCNC]] software (Windows 10) generates the motion control stream. +
-  * Sends commands (steps/directions) over Ethernet to the AXBB-E. +
-  * The AXBB-E translates them into hardware pulses for the drivers. +
-  * Operator inputs (limit switches, estop, spindle control) feed back to UCCNC via the AXBB-E. +
- +

-=== Signal Flow Summary ===  
-  * Mains AC → Power Supplies → Provide 48V (motors), 24V (control), 5V (logic). 
-  * PC running UCCNC → Ethernet → AXBB-E Motion Controller. 
-  * AXBB-E Outputs → Step/Dir/Ena → Motor Drivers (X, Y, Z, A). 
-  * Motor Drivers → High-voltage pulses → Stepper Motors. 
-  * AXBB-E Inputs ← Limit switches, estop, home sensors. 
-  * Optional: Outputs control spindle, coolant, etc.
