Hi everyone,
First let me thank all the posters on this site for giving me ideas and inspiration to try and design and soon build a working CNC router. Special thanks to Neale and his AVOR build /Clive S for his help and offer to assist me ( hope to visit you in future ) / routercnc for his build videos, gave me help with planning with epoxy.
I wanted to try something a little different by making a removable aluminium bed so it could be used as a plasma cutter - hence project Medusa. Its 2 things rolled into 1.
Anyways here are a couple of CAD drawings so I could get some pointers and feedback on areas I could improve or change. It is not finished as I have to design bolting holes / plasma holder etc.
The main body is 60x60x4mm steel welded - the end plates are 20mm Aluminium and the Z axis is a mixture of 20mm and 15mm aluminium. - sorry the ball screws are not on the picture - my computer slows down to a halt if I show them -
I will update this post as it progresses.
UPDATE..11.11.18 cost and quality are important.
Ok here is my list of electrical / mechanical parts I have in my planning stage so far.
1) BALLSCREWS ...1610 or 2010 x and y axis / 2005 or 1605 on the z.
2) LINEAR RAIL... usual aliexpress ones.
3) MOTORS...4x Nema 23 3nm
4) DRIVERS...4x Am882 or Em806 or anything better ?
5) MOTION BOARD...1x Csmio ip/m ? ( is there anything better as I have 2x motors on X and is there a problem with auto homing ?? Sorry I am new to all this.
6) BREAKOUT BOARD.. Not sure... depends on motion board ???
7) PSU... I have no idea re this at all and dont fully know the parts in the 68v build video. Can I buy 24v and 68v supply and what amp and watt do I need ?
8) SOFTWARE... I have acess to Mach 3 / 4 and Aspire Vcarve also.
9) SPINDLE... 3kw water cooled and VFD.
Many thanks again and take care.
Mike
Please can I have any constructive feedback on my design and items selected, everything is just in the planning phase still.Last edited by Hulksmash; 11-11-2018 at 05:04 PM.

I am probably going to put this build on hold for the time being and concentrate on a Mill and a CNC conversion. I will still be designing the router side of things too but I have too much steel I want to mill first.
At least with a Milling Machine I can use it to make parts for a CNC conversion and Router as its usable right from purchase. A router to have good strength and accuracy would take far longer to become operational.
*thanks Neale for helping me decide*
(does anyone know how you can tag people into your post? )
regards and stay safe everyone
