Sounded a little dry, i mean i can not gage how much time in calendar days it will take to be familiar enough with the EMC source to properly implement it, given the limited time available per day at home. :) Once i have something to test, everyone will have the chance to poke holes into that imple

I think what you're missing is that printers have an encoder strip that is only marginally wider than the paper. Going full left is not a decoded exercise. It just runs the motor 'left' for longer than a full stroke. Now when the motor moves right again, there will be some movement along the blank

Thanks, yes, G72 would be part 2 of 2. G71 is more useful and G72 would be derived from G71, ideally. I would pick 2 words for X and Z stock at random, avoids the U/W conflict. (Random, unless there is a pair left i can use together) On Wed, Jun 9, 2010 at 8:55 AM, Steve Stallings wrote: > The

The book "CNC Programming" by Peter Smid is frequently used for learning complicated CNC programming methods. It contains an easier to understand description of the Fanuc style cycles. Fanuc has implemented two versions, one called a "one block" format and the other called "double block" format. Bo

I would have taken this offlist some time ago, were it not that I am talking from a position of almost total ignorance myself, and might make some huge error that needs correcting).

I think that I give up trying to do this by myself (see below on reasons, that have driven me to the desperation) and so I would like to ask, if anyone can write a kinematics module for me and what would be the fee for that? 2010/6/9 Andy Pugh : > > Indeed, look in genserkins for an example of th
