Hey, I noticed that your timing belt conversion uses flange-less timing belt pulleys. What prevents the belts from walking off the pulleys?

Proper alignment.
Some versions of the belt drive do use flanged pulleys though.

Ran these flangeless pulleys for many months, up to 6800 rpm, never had a walk-off.

Hi Hoss, thanks for the reply. I checked out the site candcnc.com and it seems mostly about plasma tables. I can dig there a bit and contact them, but just a little confused because not much focus on mills that I could find. Anyhow thanks for the link and I will be checking out the videos to understand the process. My goal is still to buy a kit for this mill, get it running and then get another mill just like it and DIY the second one if possible. If I can't find a decent kit then I may end up with a Tormach or a Smithy mill, and I will DIY the one I have, but not for a while.

So just to be sure, is a plasma kit the same as a mill kit as far as controllers go? Also, if my mill is close or the same as a BF30, are kits already available out there?

photomankc,

Can you elaborate on how and why you lost the 0.8" of Y travel? I was under the impression that the CNC conversion wouldn't lose any X or Y travel.

Titaniumboy

Its not the conversion, I just noticed it when I had the column off and was repacking the nuts with larger balls on the X/Y table. Since I don't have limit switches I made marks to show the home positions for X/Y and when I ran the Y back by hand with no column I got well beyond the mark made for the Y home. That mark represented the rear-most travel of the Y before the table runs into the column and the bunched up rubber way cover. If I add 1" of spacer I can get that additional travel and keep the way cover and column from consuming any of the Y travel.

Now I would swear back in the manual days I had roughly 7" of travel in Y and now I only have about 6.5" but I never noted the travel down in the manual days so I'm not completely certain of what if any difference there is. I don't see any obvious interference beyond the nut mount running into the slot without the column so maybe I never had that much to begin with. Mines a PM-25 though, not a G0704.

Last time I ordered from Weiss it sounded like they where getting inundated with small orders for parts, so wouldn't be surprised if they start forwarding people to their local agents etc

The contact on this side of the pond was able to understand and communicate well in English. That carries a few points.

The suitable packages are under Plug and run cnc electronics/ router med-heavy.
If you can afford a Tormach then by all means get one.
There are no kits to convert a bf30.

The forum gremlins are causing a lot of trouble these days, working again now.

I got a good deal on a CO2 laser power supply, I think.

Seeing if posting pics is still working.

Ok, seems good to go now.

Why have I already seen the video of the new Hoss spindle?

Huh?

The laser tube arrived safe and sound.:banana:

Holy cow that is alot bigger then I envisioned.

That's what she said.

It'll fit though I may use mirrors instead of directly mounting it on the mill in an enclosure.

I wonder if the tube will last longer if it isn't exposed to so much vibration because you've used the mirrors?

Cheers,

[hoss2006]

My thinking too though the enclosure I planned would suspend the tube inside an ally square tube
with printed supports and rubber shims.
The only vibration should come from the x and y steppers.

Hoss, Have you checked out this guys vid for a CNC laser? [ame="http://www.youtube.com/watch?v=pgSefHXlIek"]HERE[/ame] Pretty neat setup all together.

Pretty cool indeed, can't wait to have fun myself.

Holy Crap you've now taken hobby CNC to a whole new level.....aaaaargh

Not only have you rewriten the book on 3D printing, the benchtop mill X2, Benchtop Mill G0704, Benchtop Mill 4th axis, Benchtop Mill 5th axis, Benchtop Mill ATC for us who are misserably trying to sift through the vast relams of info you have supplied FREE just to annoy us......and who may I add we cannot even remember yesterday not to mind the flippin website of the so and so who supplies the most outragous thingies who none of us can even remember and not to mind even pronounce the name of the what-ya-may-call-it blastet `thingymajig but in a jifi and out of the blue, you like a magician can pull out of your hat the link to the what-ya-may-call-it thingy and not only can that you have flippin loads of suppliers and can even reccomend the flippin best supplier(nuts)......

and now you're doing something with some kind of a laser.....

I give up.....
