Initial Design Check Please

Well small update, ive started building the top part of the CNC with alot of help from a close family friend.
Here is a few pics of the progress.

Starting work on the spindle brackets

Main gantry uprights and bearing plates

Gantry bearing blocks

George and i on the Miller building the spindle plate.

With regards to the steppers for the machine, would the 4nm or 3.1nm steppers be best? Im im thinking 4nm ones from cnc4you and am882 for the drivers. I wont get the drivers yet as i dont require them just yet.

Looking nice so far, it's great when the action starts. I used those stepper motors and the AM882's, they work great but you might want to look at the updated drivers, the EM806; http://www.mycncuk.com/threads/8249-...5162#post65162

I was disappointed to see the discussion about steppers - from the earlier pictures, I had hoped that this would be the first steam-powered CNC machine!

Thanks EddyCurrent, ill have a good luck. The only reason for the drives is i know they are rated and they are available for a great price on ali express.

Yes Neale, it could well be if George had his way. He has built loads of steam trucks, trains and a steam boat. He is such a cleaver guy and does all his designs in solidworks these days.

Those parts are looking great. Well, yes, if the friend who's helping you has build those fancy steam engine things then I'm sure making the cnc machine parts are going to be like Gordon Ramsay whipping up a few snacks for a kids party :-)

Thanks for the replies guys.

EddyCurrent, ive ordered the drives and the motors have arrived. Only thing is now i need to find the belts and pulleys. Ive read GT5 i the right type to get but all the belts ive seen only have fiberglass banding and not steal. Does anyone know where to get these from? Ive tried www.beltingonline.com and a few others.

HTD 5 15mm width are the ones you want and the belts dont need to be steel banded they will be fine fibregalss. Just buy a decent quality branded belt like Dunlop or Gates etc.
