Hello

Hi

And welcome to the forum

When you get your new toy, would be nice to see some photo's and video of it running.

Do you have any photo's of your current machine and parts that you have made on it?

The Machine. These days it's a wee bit tidier but I never did get round to putting the controller in a proper box. I did though put the machine in a box.

Mostly I've used it to build clocks. The so called Aniversary Clock was designed and cut for my wife on our first wedding anniversary.

Another one based on a Gravity Escapement with a compound pendulum.

A Grasshopper Escapement prototype which has never ticked a single tock.

One based on Garry's clock. Sadly his page seems to have disappeared from the web.

Someone on the Vetric forum showed how to cut an Aztec Calendar - which I just had to have a go at. Took nearly 6 hours to cut.

And the obligatory T-Rex which I think is available in the demo version of VCarve.

Finally a small Eggtimer. This was what led to the larger anniversary clock, both are based on a variation of the verge and foliot.

I'll try and do some video's of the new machine when it arrives. One thing I did read here was that two drives on the x-axis are to be avoided like the plague. That's possibly a little worrying! Anyone care to elaborate?

Its not a problem as long as they stay in sync else the gantry starts to twist - although the impact of that depends on the gantry rigidity. Therefore loosing steps on one side is a definite no no.. Usual solutions to this are one drive, belts to two screws or making sure the motors never stall out by oversizing them (using two motors each sized to do the task individually is one approach).

It has to be a law of the universe that if something can go out of sync, it will. Over sizing the motors would have the downside of potentially more damage - I'd guess it would be better for the gantry to sieze up sooner rather than later - slightly less potential to put a bend in two expensive ballscrews. Oh well, I suppose at some point I will be pondering how to realign/re-square the gantry - such are the joys of this ... err ... hobby.

Thanks for fixing the links post BTW.

I posted some links in reply yesterday but they seem to have gone AWOL.
