There are a lot of older CNC controllers with only LPT (parallel printer) port based control signals input connector. PoKeys57CNC is an USB CNC controller replacing LPT port. Moreover it allows a quick migration from LPT to USB CNC controller replacing LPT. Although small, the device is adjustable and as such requires no complex knowledge on device programming.

PoKeys57CNC USB and Ethernet CNC controller can controll up to 8 axis CNC. Most of STEP/DIR signal driven motors such as stepper motors, servo drives, etc. can be used in various applications. Moreover it can execute all other powerful PoKeys device features in parallel. Device contains dedicated connectors for connections with motor drivers, pendants, (HD44780-compatible) LCD module, etc. In addition, 5 analog inputs with 12-bit resolution are available. The device also features four galvanically-isolated open-collector outputs and isolated 0 to 10 V analog output.
The device runs the PoIL core and is also compatible with PoBlocks graphical programming software. PoKeys57CNC is the only USB and Ethernet CNC controller with integrated Programmable Logic Controller. Thus simple automating different peripherals with PoBlocks is simple. Moreover it can interchange data with other software applications that are using PoKeys57CNC device.
On dedicated PoExtBus/PoNET connector it is possible to connect different extensions. Also various additional peripherals such as PoNetKBD48CNC, PoPendant1C, PoRelay8, PoExtBusOC16 and I2C sensors extend the functions of the PoKeys57CNC USB and Ethernet CNC controller.
Controls motor drivers with direct step/direction control from a PC while having support for most drives released on the market. Connects through the USB port for maximum speed with compatibility with all modern PCs and laptops. Doesn't require additional machine control software to operate the MK controllers.
CNC motion controller is a link between personal computer and drivers for stepper or servo motors. It uses USB port which is available on all modern computers and laptops. This is a complete (software/hardware) solution and it does NOT require any additional software (Mach3 is NOT needed).

NVUM V2 is a CNC (Computer Numerical Control) controller that can be used to control a machine tool such as a lathe or milling machine. It uses a USB port to communicate with a computer running Mach3 software, which is a popular CNC control software used for a wide range of applications. The NVUM V2 controller supports 3, 4, 5, and 6-axis configurations, which means it can control the movement of up to 6 axes on a machine tool. It also supports standard MPG (Manual Pulse Generator) input, which allows the operator to manually control the movement of the machine using a handwheel or other input device. CNC controllers NVUM V2 are used in a variety of industries, including manufacturing, prototyping, and hobbyist applications.
Model: NVUM CNC USB MACH3 ControllerAs a new USB mach3 CNC controller, the nvum CNC controller board supports up to 6 axes, the CNC controller price is very affordable, and the use is straightforward. The CNC motion controller can process various patterns, and the advertising industry can also be used in multiple small and medium-sized automation equipment and instruments.
STB5100 5-axis mach3 USB controller card, suitable for all versions of mach3 software, support for all versions of Windows operating system, easy to use, very convenient for the users that use mach3 software to make engraving machine.
Wondering what joysticks will be compatible with this machine. I already have a couple of USB controllers. Would those work? Looks like the would on the standard Buildbotics controller, but it sounds like there might be some differences with this version.
This week's Lecture Requirement Mill out a PCB for In-system Programmer (ISP)
Stuff the board and solder the components
Program the board as an ISP
Test the ISP board built
Making the FabISP Board by Milling Process The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. This FabISP board will allows you to program the microcontrollers on other boards you make later on.
Probably because we are inexpereince of PCB making; our local instructor Mr Steven Chew had gave us a detail demonstration on how to use the China made PCB2020B milling machine to mill out a FabISP- based on Prof. Neil FabISP board. First up is the demonstration of how to clamp the stock FR1 PCB board on a in house designed and fabricated Jig that fittied to the PCB2020B Milling Machine as shown in the following video: Setup of PCB2020B Milling Machine From the demonstration, Steven also showed us how to setup on the CNC USB controller software as illustrate. In particular to teach the machine where is the origin: xy-position of the cut out relative to the PCB stock position and also the spindle with cutter mounted: Z-height position
Based on the schematic, the components needed are: 1x ATiny44 microcontroller (Data Sheet)
1x 1uF capacitor
2x 10pF capacitor
2x 100 ohm resistor
1x 499 ohm resistor
1x 1K ohm resistor
1x 10K ohm resistor
1x 6pin header
1x USB connector
2x 0 ohm resistors as jumpers
1x 20 mHz Crystal
2x 3.3V Zener diode
1x usb mini cable
1x ribbon cable
two 6 pin connectors
After the firmware was loaded to the microcontroller, we have to remove the SJ1 to prevent further writing onto the chip. We also remove the 0 ohm resister SJ2 to prevent electrical flow. Now we can use this as a programmer to program other boards.
One of the avenues is that the MC433 has a TWI/I2C interface and NO/Zero/nada documentation on that. The manual says it can "talk with each of the control processors to set PWM parameters, step the motors, change step sequence (wave, full or half step), change motor turn off conditions, change chop frequency and request status." which is much more than can be done withe the LPT interface (basically just step pulses). The manual concludes "The protocol used between the MC433 and an external TWI controller is described in a separate document." I have not been able to find such a document (not even on the SOC robotics own pages)
Hi Chagrin, no problem with doing the LPT ports, with direct connection from the Arduino. According to the schematics they go directly to the motor-controller (an ATmega48) so no problems with levels/currents there. The schematic shows a pullup on the limit switches and the doc says it only needs a pulldown to ground, so they should be OK to float (of course, simple enough to set up a pullup...)
