So now I need something to carry the Z axis lead screw bearings, A suitable chunk of steel was chosen to make the carrier. A tad of machining...

Next up, the two spigots of casting were machined up into something more usable. Now I have something I can work with.

Moving on, I decided to straighten out the knee, may as well start somewhere. Opening up the casting to take the new Y ball nut mount. ...

Hi JAZZCNC Thanks a lot for your reply. Could you please explain? How did you figure that out? is it form the pictures that I provided? Please...

You can't change the directions of travel. Mach3 uses the Cartesian Coordinate System, and each axis has to move a specific direction relative to the...

Where in the UK are you?

I know exactly what you mean.You ask your self this guestion all the time especially when you build something that you do not know how it is going to...

and a trailer at least four times lol, I paid £1 a kilo when I got mine but since then the guy I bought it off told me I'm a robbing bastard and...

They only charged me $1 per pound. Sounds like I better take my truck next time! Thanks guys! Wallace

Hi and If that`s the case, how would you set mach3 with appropriate directions of travel - I`m quite a novice and at one point I even had my cutting...

Yes I have to agree with you:( lol although it's not so much of a problem now that I have to modify it for the ballscrew anyway. I'll probably do a...

Ok looks to be like your running 2 drives from one Motor Output.? This isn't good and could be the cause of your troubles. So I would sort this...

I certainly do not regard myself as lucky as far as MD are concerned. I would have been better off buying a much cheaper 6040 and modding it to...

Sometimes you have yourself do I really need all that blood ;)

The difference in screw pitch will mean very little performance difference. The difference in efficiency, however, will be a lot better. Now your...

or maybe a cnc plasma cutter, hmmm.

Hmm not good to build anything with those extrusions, send them to me,lol. They look like Bosch like the other guys said, save them from the scrap...

Get that stuff out the scrappie now! http://www.aluminium-profile.co.uk/acatalog/45x45L-Aluminium-Profile-KJN992425.html I wouldn't use it for...

Yeah, it looks very much like Bosch Rexroth . Here is a Bosch Rexroth compatible profile, ...

Maybe you are a lucky one cropwell. there are plenty of others including me who have been ripped off. I will never deal with Marchant Dice (new name...

John - My caution above is born of trying to use standard 55 deg trapezoidal tips which do not always, of course, have a compatible tip radius....

I'd probably say Bosch Rexroth. Certainly the profile looks very similar.

Heh - wow - late to the party or what..! :sleeping: Duh - always check the date.! Wal.

One of the benefits of using a TCT threading tool or a tap is that it already includes the flat or radius. I just used the app, chose my fit class,...

Best if you download and look at the little app that Richard has on the Chestnut Pens website - that defines the dimensions that you need. I...

Should have said to be careful with various tool tip radii. These will of course vary the cutting dia and thus the depth of the form when trying to...

The TB6600 chip is far superior to the older TB6560 chip, and addressed a lot of the problems that caused the 6560's to regularly die. It is by no...

I simply drill a hole in some MDF about the size of the cutter dia. Harden it with CA glue and finish bore it with the tool. Then measure the hole...
