Shooting troubles

一、MKX Driver Installation

1. Download Mach3 Software

Please download the latest Mach3 driver from Mach3 official website:
http://www.machsupport.com/downloads.php

2. Install Mach3

The Parallel Port Driver does not require.
The Parallel Port Driver can deselect.

3. Prepare USB Connection

Prepare the USB cable
Connect the USB cable to MKS USB socket
Insert the other end to the PC USB port

4. Driver Installation

Windows will automatically install the driver
Wait for the driver installation to finish

5. Install MKS Card Plug-in

Copy NCusbPod.dll to: Mach3\PlugIns\
Copy mach3mill.xml configure file to: Mach3\

If you don’t copy the mach3mill.xml file, you should do the next step manually.

6. Start Mach3 and Select Plug-in

Open Mach3 software, choose:

NcusbPod-XHC-Mach3-USB-Motion-Card

Choose:
“Don’t ask me this again”

7. Interface Adjustment

If there is a black window in Mach3:

Click View → Load Screen
Choose 1024.set

Press Reset button and make it normal (don’t flash).

Now everything should be OK.

If any problem, please refer to shooting troubles.

二、MKX First Run Steps

When you first run MKS, you should configure:

Motor parameter
Home neg
Motor move way
Output and input IO

2.1 X, Y, Z, A, B, C Axis Output Configuration

Path:
Config → Ports and Pins

Enable axis (√)
Set low output
Select output

If motor moving way is reverse, please make Dir Low Reverse
Change from √ to ×, or change from × to √.

2.2 Motor Parameter Settings

Path:
Config → Motor Tuning

Set:

Acceleration
Velocity
Steps per

Each time you set an axis, click Save Settings.

Mach3 steps per unit:

Mach3 steps per unit = Mach3 steps / inch or mm

2.3 Homing / Limits Settings

Path:
Config → Homing / Limits

Home direction depends on Home Neg.

If home moving way is reverse, please make Home Neg Reverse
Change from √ to ×, or change from × to √.

2.4 Input Signal Setup

Path:
Config → Ports and Pins → Input Signals

Pin number starts from 0
Suggest Active Low = √
(Set low signal level for inputs)

2.5 Output Signal Setup

Path:
Config → Ports and Pins → Output Signals

Output IO corresponds with Mach3 #Output x
Suggest Active Low = √
(Set low signal level for outputs)

2.6 MACH3 Spindle Speed Settings

MACH3 motion control card supports the following spindle speed control:

PWM
Pulse + Direction
Analog voltage 0–10V

Path:
Config → Ports and Pins

Spindle speed control mode selection
PWM parameter settings

Parameters Setting

If using PWM or 0–10V analog voltage, select PWM control
If using stepper + direction, select Step/Direction motors

Then set maximum spindle speed in:

Config → Spindle Pulleys

The Max Speed should be adapted to your spindle.

2.7 USB Motion Control Card Configuration

NcUsbPod plugin displays:

Motion control card status
Input and output IO status
Configuration parameters

Path:
Config → Config Plugins → PlugIn Control and Activation
Click Config

Configuration Window Description

Input and Output Status
You can see input IO changes when activated or deactivated.
Output Test
You can set Output IO from 1–8 to high or low (√) when clicking ResetOutput.
Homing Status
Display whether axis home switch is active.

Homing mode selection:

NO HOMING: no homing, just clear machine coordinate
SINGLE STAGE: home over when touching home switch
DUAL STAGE: home continues when touching switch and moves back to fixed position

G-code Buffer Time Settings
Set according to PC performance. Usually do not change.

三、Trouble Shooting

3.1 Rectangle Work Becomes Round

Path:
Config → General Config

Enable Constant Velocity
Choose Stop CV on angle > 6 degrees

3.2 Mach3 Cannot Find USB Motion Card

Prompt:

Is the Xpod Inserted ok? it has ceased to respond…

Check:

Make sure USB motion card is inserted correctly
If spindle is on, make sure VFD is grounded
Make sure VFD input power has electrical filter to isolate noise

3.3 How to Ref All Home

Enable home IO
Path:
Config → Ports and Pins → Input Signals
- Enable Xhome, Yhome, Zhome
- Port# = 1
- Pin number = 0, 1, 2
- Active Low = √
Open plugin

Path: Config → Config Plugins → NcUsbPod → Config Choose Single Stage / Dual Stage
Make sure home switch signal is OK
Click Mach3 button Ref All Home
If homing direction is reverse:
Config → Homing / Limits → Home Neg Reverse

3.4 Mach3 Auto Exit When Plugging USB Card

Remove other USB devices (such as USB keyboard)
Insert USB motion card again

Mach3 Indication

Is the Xpod Inserted ok? it has ceased to respond…
USB motion card is lost
XHC ncusbpod connected
USB motion card is connected correctly
Probe ignore, active at call for probe
Probe signal is active
Too fast for pulley using max
Spindle speed exceeds maximum speed
K word given for arc in xy plane block…
Mach3 does not support the file
