My order from\u00a0Motedis<\/a>\u00a0arrived yesterday,
\nMotedis<\/a>\u00a0include any left over pieces if you choose to have your items cut from standard 2, 3, 4 or 6m lengths, instead of specifying individual lengths.<\/p>\n

I used\u00a0GoNest 1D<\/a>\u00a0to optimise my cutting plan and allow for the kerf\/waste generated by each cut.<\/p>\n

This is 4 x 6m lengths of\u00a020x20mm<\/a>\u00a0and 2 x 960mm lengths of\u00a020x40mm<\/a>\u00a0aluminium extrusion cut according to my requirements.<\/p>\n

\"\"<\/a><\/div>\n

I also purchased 50 brackets<\/a>, 10 inner brackets<\/a>, 2 hinges<\/a>, 3 sliders<\/a> and a handle<\/a>.<\/p>\n

\"\"<\/a><\/div>\n

The cutting list included parts for my Mini Kossel 3D printer<\/a> (3 x 660mm,\u00a09 x 240mm\u00a020x20mm<\/a>\u00a0extrusions and the 3\u00a0sliders<\/a>)\u00a0as well as parts for the rotary axis (2 x 440mm, 1 x 140mm and 2 x 50mm\u00a020x20mm<\/a>\u00a0extrusions), the total for all the parts from\u00a0Motedis<\/a>\u00a0came to \u00a3110.16 ($170.00) + P&P.<\/p>\n

The M5\u00a0T-Nuts<\/a>\u00a0came from\u00a0RobotDigg<\/a>\u00a0@ $7.50 (\u00a34.80) for 100.<\/p>\n

The various screws, studding (all-thread), nuts and washers, most in multiples of 100, came from\u00a0Orbital Fastners<\/a>\u00a0who provide free local delivery for orders over \u00a330.00 ($46.50).<\/p>\n

I tend to over order from them as I always need more of various random fasteners for my many and varied projects.<\/p>\n

Amber Spyglass<\/a> have been out of stock of Makerslide<\/a>\u00a0for a while, although they keep promising that it will be back in stock soon.<\/p>\n

As such I will make a start on the frame and add in the\u00a0Makerslide<\/a>\u00a0parts later.<\/p>\n

On starting to assemble the frame it slowly occurs to me that something is not quite right, firstly I seem to be missing the 2 x 580mm lengths of\u00a020x20mm<\/a>\u00a0extrusion, required for the Z table, but also I have too many 560mm, 960mm and a few other lengths of\u00a020x20mm<\/a>\u00a0extrusion.<\/p>\n

After checking my cutting list several times, it would seem that I missed the 2 x 580 lengths out of my request, but also that\u00a0Motedis<\/a>\u00a0have sent me the cut list of parts from one of the 6m lengths twice!<\/p>\n

As such I have 3 x 960mm, 1 x 730mm, 3 x 560mm, 1 x 230mm, 1 x 160mm, 1 x 140mm and whatever remainder lengths as spares\/extras.<\/p>\n

My simplest solution for the Z table is to simply make it 20mm narrower and use 2 of the spare 560mm pieces, rather than cut down 2 of the 960mm pieces, this will have little, if any, real effect on the available cutting area.<\/p>\n

I will also simply adjust the size of the larger of the 2 plates that hold the rotary axis by 20mm (it was quite wide anyway, this makes it closer in size to the other plate – I was intending to print these anyway, this will save me some plastic into the bargain.<\/p>\n

This also means that I can use the remaining 560mm length as a middle support in the power supply\/electronics bay, just like Scott Shwarts<\/a>\u00a0did in his build, do away with the sheet of Plywood\/MDF and 3D print any required mounting brackets. This should also save some weight.<\/p>\n

Here is the frame after assembling all of the extrusion pieces that I can without the\u00a0Makerslide<\/a>.<\/p>\n

\"\"<\/a><\/div>\n

I then added some of the printed parts.<\/p>\n

\"\"<\/a><\/div>\n

I reprinted all of the parts in blue so they would match the anodised aluminium pieces from\u00a0Blomker Industries<\/a>.<\/p>\n

Here is the MK2 version of the rotary axis gear that I redesigned to be slightly stronger and closer to Bart’s original.<\/p>\n

\"\"<\/a><\/div>\n

and the new 48 tooth gear for the Z axis reduction.<\/p>\n

\"\"<\/a><\/div>\n

The black set of parts is now surplus to requirements and available to anyone who would like them. They would come with 606 bearings<\/a> and micro switches installed and includes all 6mm and 12mm parts except for the laser tube mounts, (although I could probably be persuaded to print these as well), a 48 tooth gt2 pulley 6mm bore and 2 x pulleys for a rotational axis. Total price \u00a330.00 + P&P, which is still well under half the price of other parts suppliers. If you wanted to make your own M6 Z lift mounts with cage nuts like mine, I would be happy to throw in some cage nuts as well.<\/p>\n","protected":false},"excerpt":{"rendered":"
