Electronics questions ????

[CnC_BoY]

Hi to all,


First, sorry for my english, it ain't my native language. I'm new to CNC and I'm really interested. This communauty seems really cool and helpfull. I already planned the mechanical aspect using CATIA (aerospace and automotive CAD software) but I know nothing about electronics. By the way it will be an enclosed machine with a 18'' by 12'' cutting area. I plan to use a Xylotex motors/board/psu kit. What do you guys think about that? There are my two questions; 1. I want to be able to switch the spindle on/off with the computer/program. Xylotex sells a breakout board. How does it works? what do I connect where, do i need to cut the power cord on the router to connect it to the board, power to board, control to relay board? Please if you could give a little details about how it all wires together. 2. How can i connect limit switches? Can I do it directly on the board, on the parallel port, do I need another board?? Again please give details.



Thanks a lot in advance for your help guys

By the way I said limit switch directly on port because I saw that: http://www.xylotex.com/HomeSw.pdf

You have posed simple questions that require complex answers. Effectively, you're asking "how do I wire my machine???" and in some respect, "how do I engineer the control circuitry???".

As with any CNC project, project engineering and wiring are critical. I'd suggest contacting the supplier of the components you're planning to use for wiring diagrams FIRST. Most of the engineering and wiring connnection logic should already be done for you.

ONce you study them, a lot of the questions you are asking should be answered. IF not, you can then do specific research into the areas that you are not familiar with. At that point, you can also contact the vendor tech support staff. Surely , they have one and have probably answered your questions (and others) many times before.

Part of the process of DIY CNC is LEARNING. Simply getting the answers from somebody is like copying someone else's homework - you got the answer but not the knowledge.

If the vendor does not have decent wiring diagrams, you might want to find another vendor. Or, if you are not proficient with electronics/electrical projects, find help locally.

If you can't read a or create a wiring diagram, you'll hardly be able to assemble the system you're contemplating or troubleshooting it if/when you have problems with it.

There is a difference between DIY and OJT (on the job training). DIY involves the use of learned skills - OJT involves learning the skills WHILE BEING MENTORED by someone who already KNOWS them. Simple questions are fine for a message board, a complete training seminar is a bit above and beyond the level of support one should expect, IMO

Playing with electricity and electromechanical devices that have the power to hurt or kill me is something I'd NOT want to do if I was NOT well versed with electronics.

Thanks for the answer, I realised that my questions are not well asked.
I found where to get help, I study in an aerospace school and I got help from the Avionics teachers who are basically electronics engineers. They agreed to help me.
