Hi all,

The current version of JetCam will not allow the .set screens file to be saved. 

Does anyone have a copy of the earlier version (which does allow the screens to be saved as a .set file) which they would be willing to share please ?. 

Thanks,

Tweakie.

Would be nice if the latest version would save the .set file like the old version did.

As Peter has said when the table moves to the left the cutting tool effectively moves to the right of the work, which is what the Mach screen is showing. It takes a bit of getting used to but think of the jog keys as moving the cutter on the work instead of watching the table movements.

Brilliant news about getting a replacement controller.

I doubt that this controller can handle the current necessary to satisfactorily run two motors wired in parallel. But it all depends on the torque required to drive the axis, maybe 1.25 Amps per motor will provide enough torque, maybe not. You would have to try it and see I suppose.

Just a note for anyone else wishing to add one of these laser pointers to their machine.

The positive supply of these devices is often connected to the metal casing so it is best to use a Delrin (or similar) clamping arrangement, as Budman has done on his mill. This isolates the device from the machine frame and will enable powering of the device direct from the BOB and switching it on and off under Mach control, as Greg has suggested, a lot easier to accomplish.

As I have used a metal clamp the body of the device is connected to ground or 0Volts therefor I need negative volts (-3Volts) to power it. This has been accomplished using the guts of a 3Volt wall wart (fitted inside my control box) which is in turn switched on and off under Mach control using a solid state relay which is directly driven by the BOB. This has resulted in more expense than would otherwise have been necessary but what the hell it's my hobby and you can't put a price on that can you ?.

If all else fails then you have nothing to loose by trying something radical. Thats my motto.

I am sure that if needs must that you could find all the necessary skills. Think positive.

You are certainly right there Jerry - It is never ever finished.

Thanks Scott, you are a gentleman.

(I have now found the customization wiki which explains everything but will take some time to digest).
Thanks again and sorry that I am such a slouch.
