CNCTOPBAOS 3 Axis GRBL 1.1f USB Port CNC Engraving Machine Controller Board for CNC Router Engraver Milling Machine 3018-PRO 1610-PRO 3018-PRO-MAX Control Card

If you are not familiar with electronics - even at a general level - forget it. Buy one with a spec sheet and pinout! This worked great for the replacement of an older Woodpecker driver board I had go bad but no docs AT ALL. For a company with a store front and a decent web presence, how the heck can you NOT supply the least of the documentation. It is not available anywhere I can see on the net and I see others have also complained. Other than that - go for it. Works great!

Works great, at a good price. Used on cnc engraver.

This is a specialized controller board for the 3018 type of 3d mill. The fit and finish is excellent. It works out of the box, with added tweeks for end stops and the like. You do have to be aware that this is an unbuffered board made for running SMALL stepper motors and a stock 775 motor. As these motors are an inductive device, disconnecting the wires with power on can cause high voltage kick back which can destroy the board. Any short circuits, bad wiring and the like can easily do the same. The pwm output is aimed at laser cutters and not for larger motor controllers. The pwm output is 12V and can be set to 0 to 100% square wave output with grbl. Most cheap pwm motor drivers expect 5V output and won't work with these boards.

I used this to replace the board on my 3018 Pro CNC. It was virtually plug-and-play, with the only requirement was transferring over the previous settings (which are returned from an existing board by sending the '$$' command).The silkscreening on this one is correct also, whereas previous versions of the board mislabled the limit switch pins.But, since the drivers are soldered to the board, if one goes out, there is no easy way to just drop a new driver in. This does help with longevity of the drivers, since they can sink heat through the board and heatsinks, but if you make a mistake and fry a driver, the whole board is now e-waste.So, while I would say this is the best replacement board for a 3018, I would prefer one with replaceable drivers.

SIMPLE AND WORKS THE FIRST TIME

Unit did not last more than 1 day. It is pretty fragile and I took extra precautions to never unplug anything unless I powered it down first.

nice product,works good, easy to install

I picked this up after my old CNC board that ran Mach 3 fried. At the cheap price I really didn't expect much. Boy was I amazed! This board does more than my old one did, and easier! If you have any issues with the settings there are LOTS of tutorial videos online. Great product!
