Re: Z Axis only traveling in -neg direction...

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...

Re: Hercus Turret Macro

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 ...

Re: 4th axis installation

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

Re: Hercus Turret Macro

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?

Re: Hercus Turret Macro

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...

Re: Hercus Turret Macro

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

Re: Hercus Turret Macro

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...
