    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.

    Hi
    very nice build indeed . I especially like the doubling of the side plates - a weak point in most cnc`s
    Just a few suggestions:
    -you could have sealed your mdf torsion box right when gluing together and ,if i was you, i would have made (at the very least) the first and last member of the torsion box from some material a bit more dimensionally stronger than mdf.

    -Think about going belt on belt (rack and pinion) for better accuracy.

    -for less hazzle, why not use a single 25mm square rail and wagon on x (at least). trying to get 4 rails precisely facing each other might turn into a nightmare and considering cost... 4 rails and multible wheels/bearings do not come for free either i guess. Using a single 20 or 25mm sized rail, a single (long) wagon would be sufficient and is aprox 120 Euro over here (incl 1,0m rail) . It would take hundreds of kg thrown at it so no need to worry about strength.

    -z has been mentioned before.

    great work, keep at it

    greets

    flo

    I like the mdf frame. I went to build my frame. I am short some aluminum extrusion. Instead of ordering more extrusion, I think I will go with oak. I think I have enough in the shop to make a great frame. Thanks for the idea.

    Hi! I am new around. I am still getting familiar with the website. If I want to build this router is that possible? I mean, can I get the plans parts list? Thanks in advance!!

    This was a custom build that he designed for himself. There appear to be no drawings in the files section or BOM. You could always design your own of the photos. That way, you would know the machine inside and out.

    Looks great! I've been considering a belt or chain drive system for my next build as it's almost prohibitively expensive to get a 1300-1500mm ball screw shipped to me, and rack and pinion would need a little but more work to mount. What kind of feedrates are you machining aluminum in? I like the beefy belt too!

    Inhave no idea where you are, but if in the US, it is fairly cheap and easy to get a 1/2 - 10 five start precision lead screw shipped to you from McMaster - Carr. I use them on my 1500 mm Y axis. When I was calibrating the Y, when commanded to move 1000 mm it was only 0.3mm off (1000.3). FWIW, I machine aluminum at about 900 mm/min. But I only take about 0.2mm DOC with a 1/8 inch endmill and about 0.3 mm with 1/4" endmill. That being said I have been playing it safe. I notice the 1/4" makes nicer cleaner cuts (less deflection).

    I am in the US but not in the 48. Mostly it's an issue with a 5-6 foot thin rod going by airmail. UPS and similar will be very expensive. If 2 separate shipments of cbeam get to me with dents in the ends, I'm not super optimistic, unless they tape them to a board, haha.

    Mine came in a nice stout cardboard tube. I think the risks of going via air, or stopping at multiple UPS/FedEx transfer locations in the continental US and being unloaded and reloaded betweed multiple trucks may be as bad or worse. ;) They made it in impeccable shape.:thumbsup: What I did not like was the fact you do not know how much it will cost to ship until you hit the order button. I was scared, but then pleasantly surprised.
