Re: Hercus Turret Macro

Thank you Graemep:

That is great to see how someone got it working. Extra thanks for posting all the information on how this will save me a lot of time. I had not considered using the lock switch to turn off the relay.

Re: Hercus Turret Macro

Centroid actually has a website with lots of information. The CNC12 PLC programming manual Marty linked to is on their documents and manuals webpage: https://www.centroidcnc.com/centroid_diy/centroid_manuals.html I sort of got side tracked with the first manual I found. The second one has much more...

Re: Hercus Turret Macro

I'm going to follow your suggestion. I'm pretty sure I can get the turret homing and indexing tested with the counter based logic. Then centroid can take over. Although I would like to learn how to do this myself because it might help with troubleshooting in the future. Realistically it makes a lot ...

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

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 ...

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 lo...

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?

Re: Hercus Turret Macro

Hi Marty: My turret is the modified one. The one in the second drawing. One switch for home. Correct the one marked index activates when the turret passes that tool position. Reversing the turret activates a (clamp) mechanical lock. No brake or solenoid. When the turret spins forward the mechanical ...

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 ...

Re: Hercus Turret Macro

Been a while but I recently put an acorn on the lathe and am now solving the usual stuff that crops up with a new install. I'm now back to getting the turret to work. I don't want to do a macro from scratch so I'm looking at editing one. I have never made a macro before and have little experience wi...
