For the start of the process we had a few design criteria:

• As compact as possible

• Must be made of 3x3" and 2.5" box section because thats what we had a lot of stock of at the time.

• Only has to cut aluminium well and light steel

• Provisions for automation 

• Had to use the baldor motors we had on hand at the time 

• Can't draw more than 32A of current as the workshop only has a 64A supply for the entire thing including lights and server room 

• Must be fast

• Needs to not break the bank in the cost of all the components 

• Needs to use the Hywin 20mm HG linear rails we had on hand at the time.

• I started by making this model, based on the 1100MX. but as I said before, the model diddnt work for our application so it was scrapped, if you do want to have a look at it, email us at admin@stjarnor.co.uk and we will send you it! 

• The second model was much more sucsessful, this model is not avalable for download for now, until we have completely finished it. just so we can make more changes before we publish it.

• this model is much more rigid than the previous one, all the other braces and the main frame. I didd't have much stock spare, but loads of 2.5" box section so the main elecrical cabinets are being each held up by two peices of 2.5x2.5 inch box section with a wall thickness of 3mm! overkill i know! 

• All of the different sizes we used were:

3x3 inch box section with a wall thickness of 3.5mm

2.5x2.5 inch box section with a wall thickness of 3mm

20mm plate for the liniar rail guides

40mm plate for the spindle housing

30x30mm angle iron for the enclosure 

20x60mm plate for the mounting pads between it and the secondary bolt on base

38x25mm (TBC) aluminium with a wall thickness of 2mm for the secondary enclosure
