Re: DC Spindle (RC Based)

the first motor is shorter in length and diameter. it also has a higher voltage rating. it uses that higher voltage to get the higher power rating. it will also run hotter than the second. For long running jobs you would want a water cooled motor with some type of water supply to cool the motor. low...

Re: HPDE where to get it?

I wonder why it is so hard to send stuff internationally.. Its not that its hard to do. The problem becomes tracking. Or lack of. On most cases once a package enters another country the tracking stops. And it can sit for weeks in customs. Most customers don't understand this and think the seller is...

Re: 2nd Y-axis motor Parts

Almost all the parts can be had from inventables.. they even talked about offering a kit to do this same thing. Being they are putting all shapeoko kits together they might even be able to sell you a double Y axis kit with all the parts. I would email them or call them about it.

Re: Yet another percision issue

I have not noticed twist from my end plates. But definaly from the v wheels. I think that making the plates thicker might stiffen it up some. Its not really fixing the problem. Having a drive system on each side of the end plates makes sure that each endplate moves exactly where it needs to go with ...

Re: Precision issue. Where does it come from ?

It maybe worth milling a 100mm box into a piece of wood. It will tell you if you have backlash And in what direction it is as well. Backlash can be from the belt. Or from the wheels being to loose or to tight.

Re: Precision issue. Where does it come from ?

Have you done any modifications to your shapeoko? Or are you running it stock? There are plenty of ways to stiffen up the machine.
Also. Your depth of cut can also cause deflection if your trying to cut to much with one pass.

Re: More than 3 axis ?

I think the problem would be keeping both units In. Sync. It has not been done with ardiunos yet. But there were some people working on it. Lathe control is trickier than milling control just to start with because of spindle control is also needed or wanted by most people.

Re: Acme Z Axis upgrade

It has to do with the coupler tightening down on the threads. The only fix currently is to turn down the threaded shaft and make a cut spacer on a lathe to take up the room from the coupler to the now turned down threaded shaft

Re: ACME screw upgrade for Shapeoko Z-Axis

You also want the screw to last longer so making it out of aluminum or plastic would not be beneficial here. And machining accuracy would also be effected by making it out of those other materials because of deflection.
