Assembled a low-cost computer to handle the
Mach3 Mill & Mach3 Turn software, a 4-axes
LPT1 interfaced stepper controller, an LPT2-
interfaced manual pulse generator (MPG) pendant,
relay control box, & the Internet.
A more modern
approach to CNC uses an ethernet-controlled interface.

Mother Board

The Asus low-profile ENGT520 GPU's massive
heat sink covers the adjacent unused PCIe (x1) slot.

Low-profile LPT2 PCI card.

Start, Control Panel, Device Manager, Ports, LPT

In the BIOS, I turned-off the two RS232 serial
ports & configured the two LPT ports to EPP+ECP.
LPT1 is on the motherboard (0378) &
LPT2 is a PCI card (DF00). The Port #1 address
is standard but the Port #2 address can vary
so examine the computer's devices menu.


Solid State Drive (SSD)

In read performance:
SSD is 5x faster than HDD.
M.2 is 5x faster than SSD.
M.2 is >25x faster than HDD.


Mach3 Mill depicting the tool path for cutting a circular pocket.

This enclosure has a door to reduce swarf infiltration; it is effective.
The low-profile
μATX case was selected to optimize placement under the bench.

Display Brackets

Wall-mounted bracket for the computer's 19" LCD monitor.
The bracket allows the display to move vertically, pivot, rotate, & tilt.

The 4.75" x 4.75" x 1/4" plate attaches to the 4,
pre-existing M4-0.7 threaded mounting holes.

A wall bracket holds the 19" monitor completely off the bench.

The monitor bracket was lowered for improved viewing.

Bluetooth transmitter.

Upgraded to a Logitech M510 mouse with a USB
micro-receiver. This mouse has superior ergonomics
with comfortable overall shape & slightly protruding
forward/backward switches that have tactile feedback.
A shallow indent in the area in-between the side switches
locates the thumb. The bottom LED emits invisible
infrared light. It uses two AA batteries that last well over a
year. It works on one battery if a lighter weight is desired.
Only one Logitech micro-receiver is needed to interface
up to seven coupled Logitech devices e.g., keyboard.
The wireless Logitech keyboard is excellent; long lasting,
USB rechargeable batteries, tactile backlit keys, sleek.

The Netgear A7000 has excellent
WiFi throughput using USB3 & 5 GHz.


The CPU, LCD, opto-isolation, safety charge pump, &
pendant interfaces are protected by a computer monitored
 uninterruptable power supply while the stepper motor
control circuit is protected by a
n APC surge protector.

MediaServer 2

I built this server to hold my music, hi-res photos,
home videos, data, & games. iTunes acts as the media serve
The ATVs are then connected via HDMI to 60" & 75" Samsung QLED 4k TVs.
There are two, 6TB WD Black HDDs for redundancy. It is hard-wired (1Gbit)
to a Linksys WRT3200 ACM dual-band router. Both ATV 4k units
are hard-wired via ethernet to the router.

First GPU was an
EVGA Geforce RTX 2060 Graphics Card.

EVGA Geforce RTX 2070 Ultra gaming 3-slots wide GPU.
8GB GDDR6 RAM. Fast, super-smooth 4k sim. 8+6 pin power.
This GPU has an important guard plate on the back to protect
the surface-mounted micro-circuitry.

G.Skill Ripjaws V 64GB (16x4) DDR4 3200MHz RAM.

Everything was running smoothly so next,
the OEM cooler needed to be replaced.

Paste goes on next.

Rear MOBO bracket for an Intel form
factor CPU cooler install. I like that it
adds physical micro-circuit protection.

Cooler Master Hyper 212 RGB
Black Edition installed onto CPU.
Air flows into fan front then exhausts
towards the back of the case.
It pulls air over the 64GB of RAM.

The Hyper 212 cooler is so quiet & efficient.
Better CPU heat control/dissipation
allows the i7-9700 to over-clock itself
(auto-OC) up to 4.7GHz. Asus Aura Sync
program controls the MOBO's RGB LEDs.
The 2070 RGB LEDs are controlled by
the EVGA GPU's Precision X1 software.

Corsair ML120 Pro Magnetic Levitation Fan.
Specifications: 0.225A, 4-pin, 16-37 dBA,
12-75 CFM, 0.2-4.2 mm-H2O. An excellent
PWM fan with magnetic bearings. A very
efficient & quiet 120mm fan. LED colors,
available. It has nice, built-in rubber
spacers. In the Asus MB BIOS, I set all
QFan Control profiles to "silent" running.

The Logitech M510 mouse, which has excellent ergonomics, is RF.
The Logitech MX Keys illuminated wireless keyboard is Bluetooth.
The MX Keys Unifying USB Receiver, can
control both units via OEM software pairing.

After setup (software install, pairing), turn the MX keyboard
OFF then ON to make the backlighting fully automatic.

Each drive has an attached handle that acts as a spacer
to hold it in & when pivoted down, as an extractor.

This metal retainer plate snaps into place to
securely hold all four drives in their slots.

Flight Simulation

F/A-18E Super Hornet SuperbugX with TacPack
by Vertical Reality Simulations (VRS Wiki).
 It runs as a module within Microsoft FSX
with full weapons, as intended by God.
A nice F/A-18E program but
DCS World is by
far, the overall superior combat simulation.

attach the pedals using hook & pile (Velcro).

DCS World

DCS World 2.7 is awesome. The simulation is
free with two aircraft; additional modules cost.
Loads very fast from the m.2 memory card.
