    That's a lot of drilling and tapping!
    Everything looks great though.

    @Joe Santarsiero Its not as bad as it looks, although on the X axis, it is a single piece of 8040 extrusion with a piece of 2040 for the stabilizer and they are held on by 20 M5 x 40mm hex cap screws, which tapping that deep into Misumi extrusions (they don't have the debris channels like 80/20 extrusions) is a time consuming process! Taping the plates is not bad though; I just grab my tap and go through the holes while I'm cutting the next piece!

    @JustinTime Those 6mm belts are great for 3d printers, but have too much flex over long distances to really be practical for a heavy router. In comparison, that 15mm belt is like a tank tread! They are not expensive relatively speaking ($60 for 5 pulleys and 5M of belt shipped free), but I can only find them from China on Ebay which takes about 3 weeks to get here.

    @Julius I LOVE Vslot for "clean" bots (printers, drawbots, etc.) but not a huge fan of it for "dirty" bots. On my 1500, i will keep the vslot Z because the worst thing that I will cut with it is hardwoods and acrylic, but for my 750 I will eventually go with dual 16mm fully supported rods as soon as my budget allows. I have found that when cutting metals (I use it ALOT for aluminum and brass) that vslot is very unforgiving of debris and deforms very easily when brass or aluminum gets into the slots.

    That is also another reason that I went with open rail for the X & Y, so that if anything does happen and it gets damaged, it can be easily replaced without buying all new extrusions! This router was designed to be a tank built on a bicycle budget and believe it or not, (I will have to double check my receipts to be sure) but that 1500 came in at around $700, motors, hardware, and electronics included!

    @Lstj No, its just a $25 harbor freight trim router. The one on my 750 has been in service for about 3 years now without a single problem and all I have had to do is change out the brushes once about a year ago! Actually, it is the same router that cut all of the parts for both of these machines.
