Good Day,
My name is solomon, from Ethiopia,
I want to automate or control 3-axis cartesian robot( CNC router ), Conveyor and other machine during specific operation.
The operational flow chart can be separated into three parts:
1: CNC Router and dispencer
2: Conveyor
3: Pneumatic System
So that, I kindly request you which type of Microprocessor/CNC controller or PLC from your product can handle this matters
Kind Regards
Start by looking at a Alan Bradley they make good equipment, Siemens is good as well. I have no idea what is available in your area but you can check with your local industrial electrical distributor. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
Gil
There is not really enough information to give you specific advice.
Are you under any price constraints budget for each item ?
Do you have the time and resources to make your own devices ?
What is the maximum expected size of the CNC produced item ?
As gilshultz suggests if you have a decent budget and there are other constraints then a commercial system would be better.
If you have fewer limits there are a few Arduino options also open to you that in many cases will come in very cheap compared to commercial options and probably allow for a little more customisation.

Dear Gil,Bob,
Good Day,
Thank you for you prompt reply and information you provided.
First let me tell you for your information,
I believe industrialization is an engine of growth for developing country like Ethiopia nonetheless, we do not have proper history experience in automation and open to accesses & to get locally industrial electrical & electronic Items as well as distributor.
Concerning Gil Answers,
I understand that you suggested to use PLC to control or automate CNC Router , Conveyor and other systems.
If so, I have questions ,
How to Control 3-axis Cartesian robot with PLC for using router with out CNC controller?
As far as concerning Bob answers,
Q: Are you under any price constraints budget for each item ?
A:Yes I have price constraint, thats why i studying to get this items with minimum cost
Q: Do you have the time and resources to make your own devices ?
A: I have time but I tried to build my system using minimum resources
Q: What is the maximum expected size of the CNC produced item ?
A: X=600mm, Y=600mm, Z=10mm
Finally I have question
How to Control 3-axis Cartesian robot with PLC for using router with out CNC controller? considering other Items
Using open source you have a LOT of cheap options.
Many are actually available "off the shelf" so to speak.
A simple UNO with suitable motor drivers and stepper motors, can constitute a CNC controller as stand alone or computer assisted CNC. which is also capable of the task you describe.
There will come a time when you have to add quite a lot of actual details.
Budget. Time available, equipment already available. etc.
One of my machines although not as big as your requirements was fully home made using drawer runners and salvaged printer parts.
When considering your dimension needs you should consider that you will need EXTRA length to the X and Y axis so 600mm would be at least 650mm to allow for mounting.
Add to that the width of the Y carriage so if the Y take up 100mm width the X would then be 750mm.
That is a considerable width without due consideration of any sag that may be introduced which means you would have to select the parts with rigidity in mind.
Another very important factor would be what the Z axis is going to do as its task.
If it was just used as a pen plotter than the weight consideration would be quite minor.
If it is holding a laser then that would add a small extra amount.
If it was used with a spindle that would add a lot of extra weight and vibration concerns
I hope you can see how I am looking at your issue to break it down and take each part as it's own issue.
Bob.
