Centroid Community CNC Support Forum

I am new to the Centroid Acorn product. I have a homemade CNC with dual drives for the Y and Z axis and a single drive for X. I have also recently experienced this same issue. I started the system up and did a home step and the X-axis only would move in the positive direction. After some playing ar...

That last manual you linked is a good one. I searched for something like that and found one for programming macros. It did not have the detail that the last linked manual has. It's the sort of information I was looking for. Lots of detail about the process. Thanks You can proceed how you like, but ...

I'd find my fourth axis first. Then find a DC brush servo, of which I have several.

Thanks Marty now you have pointed me in the right direction on a couple of things. Yes the two inputs are good but I need one more to check turret lock. The tool table enable to turn off the power to the motor is a good one. From the centroid schematic there is only one output. The turret is either...

With encoder signals, you want good solid connections.
I think you bought some of the appropriate encoder cable too correct?

Marty

You are correct about how it operates mostly. When the turret rotates past the desired position the output that moves the turret forward will turn off. A second output will reverse the the turret for a fixed amount of time (to be determined by experimentation) Then turn off. Then the control will l...

That link has more information than the ones I have seen in the past. I'm pretty sure I understand how the turret works. My original question from today remains though. Can I edit the counter based macro from centroid or do I have to start from scratch? Its not the Macro so much as it is the PLC. H...

Yes, you should wire that 0V to COM
You have 8 wires and the shield. The shield carries through and eventually gets soldered to the DE9 shell

Hi Marty: The turret has a home switch output and a counter output. To find home the turret rotates forward until the home switch sends a pulse. Then it stops and reverses for a second to lock it in place. Once it is homed when you call a tool position it rotates forward. Each time it passes a tool...
