## Overview

The UC100 USB to Parallel CNC Motion Controller replaces outdated parallel ports with a high-speed USB interface, supporting up to 6-axis motion control and pulse rates up to 100 kHz. Designed for seamless Mach3 software compatibility, it offers easy installation and smooth, precise CNC operation in a compact, lightweight form factor.

## Description

USB Motion Controller Automatic Firmware checking and Firmware update. Motion control on up to 6-axis (X, Y, Z, A, B, C). Configurable maximum stepping frequency, the options are 25kHz(with 20usec pulse length), 50kHz(with 10usec pulse length), 100kHz(with 5usec pulse length). 12 5Volt 20mA (TTL level) buffered outputs with current sink/source capability. 5 input pins with at 5V (TTL level) with Schmitt triggered filtered inputs internally pullup to 5Volts at 4.7kOhms. 100% LPT port compatible pinout. Does not include a DB25 gender changer, So if your breakout board has a female connector, you will need to add one of these gender changer: A19. Note that this device is not optically isolated and will make the grounds of the breakout board common with the grounds of the PC. Faulty wiring on the controller could allow a ground loop with the main power supply, which may cause damage to the UC100 or even the PC. Using this isolator board will protect your system: C83

Review: UC100 - A Solid Upgrade - I have an old desktop PC running a clean copy of XP (no internet connection, no updates, boots fast!) with Mach3 with an old parallel port with 2 non-fucntioning input pins. This connects to a K2CNC 2514 machine controller. I decided to migrate to a USB port and eventuallly updat the PC with a current opeating system so I needed to get away from a PP first. In addition this would free up the CPU. I had several concerns that maybe Mach3 would not play nice, drivers would not load since I do not have an active internet connection on that PC, USB port was 1.0, etc.(whine). I am very happy to report that none of those concerns materialized. I was able to deactivate the Mach3 pulse engine,load drivers, and install plugin and Mach3 came up running. I did not even have to make any adjustments to Mach3, the steppers sounded smoother already. I have cut several parts and do not see any issues. The UC100 was well worth my investment!
Review: It simply works - I was having continual issues getting my Win7 32 bit PC to talk with my Gecko G540. For whatever reason the address of the Parallel Ports didn't work. Tried formatting PC and installing a brand new parallel ports (7 different ones were tried... none worked). Tried replacing my Gecko (Shawn @ Zenbotcnc was kind enough to ship a brand new one to me), etc... nothing worked. I'd given up. Then I decided that I might as well give the UC100 a shot. Installation was a breeze as was the configuration with Mach3. The moment of truth was here, I turned on my Gecko, fired up my spindle and voilà! IT WORKED!!! I should have tried this months ago.

## Features
