DevCnc Foam by the devCad Team



 

DevCnc Foam, supported controllers

The list of the actually supported controllers includes:

  • Theremino Master Usb module. You can use this to build your own Usb controller or to create an Usb interface to an existent Parallel Port controller
  • Arduino Mega2560 + Ramps 1.4. An economical and almost  Plug&Play controller, developed with 3D Printers in mind, transformed by the DevCad Team in a high performance foam cutting controller, rewriting the Arduino Firmare. No hardware modification or rewiring is required!
  • Arduino Mega2560 Naked - Parallel Port Interface. You can use an Arduino Mega 2560 board to connect your preferred stepper drivers, or to create an Usb interface to a legacy parallel port controller. 
  • Arduino Uno + Cnc Shield 3.00. An economical and almost Plug&Play controller, transformed by the DevCad Team in a high performance foam cutting controller, rewriting the Arduino Firmare. No hardware modification or rewiring is required!
  • Arduino Uno Naked - Parallel Port Interface. You can use an Arduino Uno board to connect your preferred stepper drivers, or to create an Usb interface to a legacy parallel port controller. 
  • Arduino Due Naked - Parallel Port Interface. You can use an Arduino Due board to connect your preferred stepper drivers, or to create an Usb interface to a legacy parallel port controller. 
  • Arduino Mega2560 + Ramps 1.4 with rotary axis. An economical and almost  Plug&Play controller, developed with 3D Printers in mind, transformed by the DevCad Team in a high performance foam cutting controller, rewriting the Arduino Firmare. No hardware modification or rewiring is required! This controller now can also manage the 5th rotary axis!
  • Arduino Mega2560 Naked - Parallel Port Interface with rotary axis. You can use an Arduino Mega 2560 board to connect your preferred stepper drivers, or to create an Usb interface to a legacy parallel port controller. This controller now can also manage the 5th rotary axis! 
  • Arduino Due Naked - Parallel Port Interface with rotary axis. You can use an Arduino Due board to connect your preferred stepper drivers, or to create an Usb interface to a legacy parallel port controller. This controller now can also manage the 5th rotary axis! 
  • FoamCutCNC - Ready to use full featured controller with rotary axis.  This is a high end controller, ready to use, offering the best performance available by devCnc Foam. It allows the control of a 5-axis machine (4-axis plus rotary table), and is complete with the entire wire heating control section. The recommended controller for your Cnc foam cutting machine

(1) - Indicates if devCnc Foam can manage the 5th rotary axis using this controller.
(2) - The number of pins used to detect the hard limit alarm. If the number is less than 4 some axes will coupled.
(3) - The type of Hot Wire control supplied by this controller. If the type is Pin Signal you can apply for example a digital rele' or something similar.
(4) - Indicates if the controller can manage the Motor Enable. If not the stepper motord will be always enabled or you can apply your one external switch.
(5) - The type of math algorithm used to generate the step sequence. Follower type can give faster speed/stepper frequency, but performs a poorer path control. Deterministic type needs more processor work, so it gives slower speed/stepper frequency, but the path control is more accurate.
(6) - If the controller is 'Naked' you must use external stepper drivers, so this value in not available. If the controller includes a Cnc shield the value depends non stepper driver type, for example DRV8825 or A4988.
