If you have Capital installed on a network, in order for the workstations to run you must also perform a network client install on
each workstation. This will prepare the station to run our programs.
The program winclient.exe contains only the components needed for a workstation to run the program from the server. It is not the entire program.
If you do not have Capital installed on your server, please contact us at 517-324-9100 or email customerservice@capitalrating.com to get it.
To download Capital's network install program:
- Click Download WinClient Now below.
- When this dialog below pops up select Save. Should any security questions come up just click ok to each.
- In the Save As dialog, browse to the drive and directory on your file server where Capital is installed.
Once there save Winclient.exe.
Bl-mach-v1.1 D302 =link= Jun 2026
You must use a true DB25 parallel cable . Note that generic "USB-to-Parallel" converter cables often do not work for real-time CNC control.
Flexible input levels support 5V drivers for broad hardware compatibility.
To configure the board in Mach3, navigate to under the config panel and use the following parameters: Bl-mach-v1.1 D302
: Ensure your PC's BIOS is set to EPP or EPP+ECP mode for the LPT port to ensure bidirectional communication (essential for limit switches).

BL-MACH-V1.1 D302 Technical Specs Summary Specification Compatible Software Mach3 (and parallel port-based software) Axis Support Up to 5 axes (X, Y, Z, A, B) Isolation Optical coupling on all inputs Spindle Control 0-10V Analog Output & 5V Relay Peripheral Power 12V-24V DC Digital Power 5V USB (or external) Dimensions 70×90×20 mm Weight Typical Applications
The (often cataloged in component databases under technical batch or firmware identifiers like D302 ) is one of the most reliable and affordable 5-axis breakout boards available for DIY CNC builders and small-scale industrial automation. Designed to act as the bridge between your master computer and individual stepper or servo motor drivers, this board interprets commands from control software via a parallel port interface to orchestrate precise machine movement.
