My first ever built CNC router.

[driftspin]

Hi to everyone here,

I've been working on a design for a DIY CNC Router for a little while and recently I said damn it, I need to build it. I've kinda gone headlong into it and started to order bits (probably a mistake) but I wanted to get some professional feedback to hopefully put my mind at rest a little.

I've attached 2 pictures of the frame work and also the completed (well almost) design. Its designed to take 400x400 materials with a rough cutting height of about 120mm. I plan to use NEMA 23's @ 2.2NM and 1.5kw spindle (er11) collet and it will hopefully be used to cut aluminium, delrin, brass (Maybe) etc. 1605 ballscrews and 20mm linear rails for the guildance.




My goal was to try and make one for about £1000 but as I've added all the extra bits its about £1300 at the moment without any control costs. I think its more than likely £1500 by the time its all there.

These are what I have ordered so far as well as the ali extrusion and metals, nuts and bolts etc.

I have some concerns after I ordered these bits, more so as I started researching more whilst waiting for them to arrive. The linear rails and ballscrews have arrived and seem great, some of the rail blocks need looking at but I see that's a common thing. My spindle also arrived with the VFD which sadly doesn't have a ground point so I need to figure that out at some point. Still waiting for the steppers but after reading up about the drivers and power supply I am a little concerned they won't be up to the job.

I am currently learning as much as I can about the wiring and I think I am getting there with that but I do have a little confusion about the number of power supplies I need in total especially as I plan to use homing swtiches. Each day is definitely a learning curve.

Originally I was planning on using the Breakout board that comes with the stepper kit but adding up the extra costs of getting a serial computer and mach3 or even using LinuxCNC I am kinda now leaning towards a DDCSV2.1 for offline control. With that in mind I use Fusion for CAM so I'll need to sort a post processor out.

Anyway, enough of my ramblings. I'd be very much interest in any feedback or suggestions you may have.

Thanks

Hello Tim B,


Welcome to this forum.

This one of the best places to get information on diy cnc builds.

Most people post their ideas and design concideration in a ( pre ) build log.

So people can help you narrow down any options you have for size machine, materials to use, purpose of the machine, trusted suppliers, budget and so on.

Any 1st reply to a build log starts with don't buy electronics kits.
Finish you design before buying anything.
Post design pictures
Ask for critique


So you don't waist any money.

I have one cost nutral tip.

Swap the bearing blocks and rail on the z axis.
So the rails are on the moving part of the z axis.


You will find here what you are looking for.

Grtz Bert.
