Hi Irving,

Sorry I've been quiet - took a while to get the printer going again and I've been busy - the new firmware needed all the accelerations and speeds sorting as well.

Where do we go from here? Two options I think -

1. I've got a very simple set of gears working which I can send you to have a look at (I gave up on the idea of destructively testing them, the originals weren't far off requirements and these are a lot better). PM me an address if you want to do this.

2. I can just build some gears to your spec - should have some time on Tuesday. If you want to do this, could you send me the latest drawings.

Mark
