Autonomous Xylotex

[Sanghera]

Hi,
Is it possible to have some sort of unit compatible with the Xylotex to run it without the computer sending pulse signals. Can you run it with a device that can send pulse signals, interpret the home switch/limit switches, and emergency stop?

Also, is there anybody making DIY joystick/keypads for the Xylotex?

Thanks.

You could do it with a D0-05 or D0-06 PLC from Automation Direct. But your top step pulse output frequency will be fairly limited. An Omron CP1H micro PLC will put out a much higher frequency and control 4 drives to boot, but is quite a bit pricier. But with either option, you are looking at a profile you must preprogram. Then there are microcontrollers, etc. So yes you can. But then it depends on what you are trying to accomplish.

I was just wondering what it would take to do this. I thought it would be nice to be able to do what the www.carvewright.com system can do. Program on the computer, take a memory card to the machine, and cut, don't worry about dust and chips getting in your fans. I think I might be better off with just an old computer doing the work.

Hey Mike,
How does the programming for the PLC work? How can the PLC get the g-code, and translate it into pulses? Or would each program have to be turned into another format?
Thanks.

check this out, its still in the beta stage I think.

Translating from G Code probably would not be a fun project with either of the PLCs I mentioned. The intent with those is for much simpler, repetitive type control. I think the microcontroller would be a better approach, but just think how much goes on in Mach or TurboCNC to get smooth coordinated motion. Now try to put that functionality into a microcontroller. It can surely be done, but by whom? It would certainly be a time consuming effort.
