Centroid Community CNC Support Forum

I am done with the controller mechanical (housing) aspects of things. I am starting the wiring. The Acorn controller will be connected to Gecko gr214v drivers. From the various posts I read, I have the options of going to the db25 or the screw type "H" connectors. From the looks of it i could go both ways. Where I get confused is the "pull-up"/open PNP/5V push / pull logic". Motors voltage will be 48 Volts.

How does the limit switches logic operates? Beeing in series the contoller cannot know which axis is tripped. (Just curious)

Also, I noticed there is a cold joint/corrosion on the back of the board where the Seed risers are connected. I have not yet powered the board but I have a concern it might affect the contoller's interface. Please advise
While registering i was asked for the board serial number. Cannot find it nowhere.

Hello and welcome to the forums,
1. Stepper drives are connected to the DB25 port, generally using a DB25 breakout board.
And AC servo drives are connected at the screw terminals.
This is covered on page 34 of the Acorn install manual: https://www.centroidcnc.com/centroid_di ... df#page=35
2. You're correct; when wired in series there's no real way of knowing which one was tripped exactly.
When tripped as a limit switch you'll need to use the limit switch defeat button to move the machine off of the switch.
With this in mind you may consider using 1 input per axis for the home/limit switches rather than 1, if you have the open inputs that is.
3. This doesn't look like anything to be concerned with.
A little hard to tell from the pictures but that may just be some flux used for soldering.

You can find the serial number if you power up the board in the CNC12 screen, or in a report generated.

If you purchase a license you have to send a report anyway

Go step by step from the installation manual and it is easy to setup your CNC..

I prefer one input for each axis for a HomeLimit Sensor.
