The BOM here is intended to be the official BOM for the laser.

http://www.buildlog.net/cnc_laser/erp/bom.html

This BOM is only for the Mechanical platform for the laser. All the electronics, are not part of the BOM. The wheels on the carriage are still the original single bearing V wheels and should be replaced with the dual bearing wheels. I will try to fix that in the next few days.

So I rolled with this, placed my boltdepot order, and my stuff arrived today. I noticed the the screws are philips pan head screws (mostly) instead of socket head cap screws... Hopefully that's a non issue, otherwise I've got a nice pile of stainless screws for my 'junk drawer' LOL :) I'm sure that many places it probably doesn't matter... Just a little feedback from my order :)

Good times... :)

In some cases, it makes the most sense to buy from McMaster, otherwise, Boltdepot is cheaper if both it and fastenal have the same part. You can get all the annoying nylon spacers from Fastenal. According to my spreadsheet, without shipping, this reduces the 'McMaster Car BOM' from about $280 to about $86.

I should note I zeroed out the 5mmx10mmx1mm shims; these seem to be for the v-wheel/idler bearings, but now that we're buying those as a kit they come with, don't they? Also, in some cases, such as the spacers, the exact dimensions weren't available, so I generally chose the closest fit. In any case the difference is in the .02-.04" range.

Grr. I wish there was an easy way to embed that list here. Here's it in CSV format:

edit: Just realized I used the old BOM and not the new one listed here, so it is probably possible to save another few dollars eliminating depricated parts.

Re: "New kit" BOM with sources

If you got Philips pan heads instead of hex socket caps, Boltdepot screwed up your order. Check that you actually ordered the right thing, then contact them. Don't let it slide. The Philips screws are cheaper. More importantly, they are more difficult to tighten firmly, especially in confined spaces.

Re: "New kit" BOM with sources

I'm pretty sure the error is mine, not theirs. I'll respond at length later when I get a chance to sit down and double-check my own work. The order was cheap enough I'm not out anything significant if it was my lack of attention.... good quality hardware, I'll find a use for it. I've gotta give them kudos for fantastic packaging and super fast shipping, either way!

<Revised>

Indeed I did find some errors in the bolt depot part numbers from the list above from Praxis (no big deal, it happens). The ones that I've found so far (I'll do an exhaustive compare later, but I think I've got the big hitters identified) are as shown

Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M3 Thread, 30mm Length, 0.50mm Pitch boltdepot # 6385
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 10mm Length, 0.80mm Pitch boltdepot # 6407
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 12mm Length, 0.80mm Pitch boltdepot # 6408
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 25mm Length, 0.80mm Pitch boltdepot # 6411
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 30mm Length, 0.80mm Pitch boltdepot # 6412
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 35mm Length, 0.80mm Pitch boltdepot # 6413
Metric Class 12.9 Socket Head Cap Screw Alloy Steel, M5 Thread, 45mm Length, 0.80mm Pitch boltdepot # 6452

The part number shown are what I believe to be the equivalent boltdepot part numbers, be careful as the part numbers shown previously for these (a few posts back) are the correct length and material, but are in a pan head phillips configuration. I'll know when I compare the costs if there is actually money to be saved, knowing the correct part numbers now for comparison.

ON a side note, my order from misumi should arrive tomororw. I can't wait!

I went ahead and rolled with the philips bolts, and put my frame together tonight. It wasnt worth the hassle to order another batch, Ill fill in holes as needed if necessary, but they worked out just fine.
