Great idea. I assume its much cheaper than the ground rods and linear bearings? Perhaps you should add it to the RepStrap page.

Thanks teddy,Quote

Nicely done.
I was contemplating the second Z support - could you be a gentleman and remind me what size the extrusion is (width not length)?

Ray, I keep trying to track down a supplier of Carbon Fibre heating tape. It's used in lots of 12V and 240V heating applications - like heated seats, gloves etc. There's some on Ebay but it's in the Russion Federation so might as well be on Mars. Anyhow, just thought I'd mention it.Quote

I should be able to do an A4 sized print bed pretty easily in the current frame, when I get round to X and Z I intend using 500mm extrusion there too, but will have to look hard for a heated bed big enough to use that much space.

Downside is there will be an extra control unit to power up before printing. I can't see myself rewriting the pronterface software so it could manage 2 heat beds...and the net is so slow on this boat even searching for whether the duet has enough ins and outs for such a thing is patience testing. I had a look last night and large beds were hard to find.

If someone can point me in the direction of where to get the extrusions, sliders etc, I may well start to build one of these monsters!

Hi Mike, I got my extrusion from here [www.aluminium-profile.co.uk]

This is a horrible mock up but oh well (<5minutes - it is bed time) - laugh at will Roughly what I plan to do. May turn it into a box too...shrug.
Mike I am going to put together my parts list tmrw evening.
I am happy to undergo this mod journey with you - unfortunately I won't be able to commence the build until (hopefully) the 17th, or (more likely) the 28th due to work away from home.
Will post when I work out what I am doing with the mosfets - probably make a design so the controller box fits it all- may as well make it so it will take the Duex4 at the same time...
will let you know..

The only tweak I'd do would be to add a 68 Ohm resistor in series with the gate of each MOSFET to combat ringing form the inductance of the connecting wire back to EXT_FET
