They're finally here!
The long-promised CNC control boxes from GeoMcnc (Say G-ohm CNC) are available at:
These are plug and play, FULLY assembled units with built in 34V, 4amp linear power supply, parallel port "breakout" built into the 3 axis, 3 amp microstepping unipolar chopper driver board, with option for screw terminal or Din5 motor connectors. The Estop circuit and switch is built into the board for added safety, and the single board design minimises point-to-point wiring for excellent reliability. (The Db25 connector is soldered to the board, and the Din5 connectors are also directly soldered to the board.) There is a 2x20 expansion header with logically laid out pins--you can access all inputs including 5v and ground with a 2x5 connector. The parallel port outputs may also be connected--including 5v and ground--using a second 2x5 connector.
(We have daughter boards in process as well which will take advantage of this simple, logical upgrade connector. It may be used to re-configure the driver board pinout to YOUR specific CNC control program.
The included fan with filter presents clean air to the driver heatsinks which are oversized for excellent heat dissipation.
A great deal of upgrade-abilty is built into the basic design and replaceable front and rear panels in the box allow you to add features like spindle and aux control, limits, probe, serial, Digispeed, modio, 2nd port, increased power supply amperage, etc. now or later.
More importantly, these CNC control boxes (MCU's) are initially being offered as a COMPLETE set for three axis desktop machines (you can upgrade to 4 axis later if you wish). And with 34 volt drives at 3 amps, machines larger than "desktop" models may also be driven.
This complete set includes the control box, power cord, serial cable for computer connection, Mach3 demo already configured for the control box, three motor cables, and three 116 oz. in. 3amp size 23 motors with a very flat torque curve; which makes them easily the equal of larger motors in actual use on a machine... (Larger 200 oz.in. motors are on the way, and may be ordered now--email for details--)
No longer do you have to worry about your electronics experience level to complete a cnc machine. No longer do you have to search for various parts from various places.
NO soldering, no screwdriver required. just plug the cords into the box and motors, load Mach3--or any other "common" step/dir p-port controller; but the M3 config is already DONE for you!---and begin using the system with YOUR CNC machine.
AND, these won't take up more space on your bench than your machine!
At only 3-3/4" wide, 5-3/4" high, and 8-3/4" long; they are about the size of a large brick. AND they are designed to minimise the footprint needed by standing up instead of laying flat.
These boards, boxes and power supplies have been in testing for over a year, and have proved reliable and FAST.
For a limited time, these complete sets are available for $325...
(limited by quantity, so time will depend upon sales levels)
Order now. Paypal ordering lets this fit on a credit card; Please email if a different payment method is desired.
P.S. CNCresource.com also have GeoMcnc MCU boxes with power supply and upgrade panels pre-drilled and wired for use with Xylotex 3 and 4 axis drive boards; HobbyCNC 3 and 4 axis drive boards, THS single axis boards. Up to 3 Gecko 201, 202 or 210 drives will fit, use of 202's may require giving up some IO upgrade space. Email for details of your specific need. (We've likely considered it and have a drive box suitably arranged.)
