Help needed proofing newbie control schematic.

[AndyUK]

Yeah, you're right I didn't read it correctly. Ignore my comments about the SSR.

This is my circuit diagram:

Makerbase MKS DLC32 MAX CNC Router Board:

You wouldn't even need to write any code to get this working.

Hi AndyUK.

Wow, just looking at your schematic, that must be one big machine, the schematic is way above my skill set unfortunately, I will try to gat my head around it, but don't forget i am a novice.

I understand machines, I am a time served Tool & Die maker, but that was 55 years ago now. I am probably, on a scale of 1 - 10 a 5 when it comes to electrics/electronics.

Regards.

Hi again AndyUK.

I have spent all afternoon going through your recommendations and schematic. I must admit, I like the idea of a standalone controller, it means I will not need to use my laptop directly. There appears a lot of equipment on your schematic, I will not be needing. If you can remember my first topic I need the controller, 3 NEMA 23 Stepper motors & 3 Stepper drivers, PSU + E Stop, my router is 240 vac.

Will my chosen Motors and Drivers work on this controller, my gut say's yes, but my brains not so sure.

Ray,

Taking into consideration all of your responses to all of the threads you have posted, my conclusion is this;

You want to make guitars so just buy a cnc machine that is already built, be it new or second hand,.
It's going to be easier, faster, maybe even cheaper,I know this because of my own cnc journey,

Thanks to this forum I came to understand the fundamentals of cnc machine design and then thanks to my existing electrical and mechanical knowledge the build was quite easy.
It did take me a while though so think how many guitars you could be making rather than fighting with putting a cnc machine together.

Off the top of my head here's a list of items that have to be considered, then you also need the tools and equipment in order to fashion them.

aluminium for frame
fasteners
Linear bearings
linear rails
ball screws
ball nuts
ball screw support bearings
timing belts
timing pulleys

stepper motors
drivers for stepper motors
spindle motor
control board(s)
relays/contactors
panel wiring
flexible cable for steppers, spindle, switches
energy chain
wiring terminals
enclosure for electrical equipment
trunking for wiring
din rail
VFD for spindle(possibly optional)
Power supplies
switches, buttons, indicator lights
limit switches
homing switches
fuse holders

Hi EddyCurrent.

Thank you for your input.
Building and repairing guitars, is to me an hobby. I also play Both Electric and Bass guitars. I do it because I like it, and at my age (77 y.o.) starting to suffer with Arthritic in my hands, it became obvious to me that if I wanted to carry Building guitars (repairing guitars does not need has much handwork as building from scratch) I would have to have a machine to help me or find another hobby.

At 77 it is a bit old to start a fresh, so after a long period of thought, I decide on a CNC machine, as I have previously stated I built a small Milling machine and converted that to CNC control (Mach3) some 20 years ago, I thought, what could be more difficult? I know now I was wrong. The world of CNC as moved on quiet a bit since those days.

I do not want to give up my hobby, so I started looking for used machines, you can find more "Rockinghorse Shit" than you can find used CNC routers, as for new ones, it became obvious to me earlier on on this journey, that I, as a pensioner, could not afford to by a machine that would suit my needs (I have seen many, or most over £1000.00) so I thought, surely I have the skills to build my own. As previously stated, I am a Time Served Tool Maker, with a fair knowledge of electrics, but needs an helping hand with the said Electrics/Electronics, at least if I built my own, with the help of Like minded people such as yourself, I could do this more cheaper, and get satisfaction knowing that I built it.

Your help is much appreciated.

Regards.
