Show"N"Tell ( Your Machines) / Re: Khadgar's DIY CNC machine
« on: January 29, 2013, 12:50:51 PM »
Thanks. my first few designs we're pretty much crappy. I came to this design by talking with a guy who owns small company(5-10 people working) that builds you could say DIY CNC machines. First my plan was to have two ball screws for X axis but that guy said it's waste of money and he suggested that i put X screw under the "table". Rest i copied their design cause it was only logical thing to do. 
I added some support made from iron L-profiles for working table that for start will be from MDF.
All parts on picture will be from alumium(ofc except screws and linear shafts). Gantry(Y+Z axis) will be around 15kg that is reason i didn't made it wider. I already said in my first post i will use this for hobby or some small business so i went for maximizing working area cause i don't have room for big machine. Here is link to that company http://www.cnc-centar.com.hr/strojevi.html they only got croatian language but pictures say everything.
I'm still not sure what electronic i will use. So faar i found a lot of 3 axis kits on ebay for 40-60$(motors not included) that suits me fine for start.Maybe later i will build PICstep driver from Alan Garfield i got 90% mats for it and my hope is should be better then ebay one. Then i need to find some decent break out board to use it with PICstep.
So faar since my first post i haven't moved very faar. I'm playing ping-pong with guy in that company i send them planes in DXF file and he said send me in corel,then i load DXF to corel and he says file is empty... Last week i draw parts in corel(and i suck when it comes to drawing in corel) and still no reply. I guess i'll need to sit in my car, bring inox shaft i plan to use for linear guides and knock with it on he's door.

and since then i cooled a bit but still don't like how it looks. How far did you progress with making windows-look-a-like mach3 screen,is there some working version of it? I'm in process of making my own DIY cnc machine so i'm checking in advance program support so when i finish cnc i can start to practice on real material.
