Re: [CAD_CAM_EDM_DRO] Encoders on stepper motors.

Dan:

You have raised some very good points. I think at some time in the future
I may indeed add encoder support to Master5. I will take you up on your
offer when I get to that point. I have alot of work in front of me to
redesign some sections of my code to allow for tighter conformity to the
concepts involved. As a relative neophyte to CNC, it never ceases to amaze
me how many in's and out's there are to this business. This group has been a
wealth of information to keep it all straight. I had thought, when starting
Master5 that the problems were fairly trivial, but a windows real-time
control is a very difficult thing to arrange. The need for accuracy as well
as speed and optimiztion is something that can be very hard to bring
together, it often seems like one advantage (code wise) bring too many
disadvantages to the overall workings of the package. This is probably the
reason why most controller packages are so different, that the initial
design of the software dictates to some extent, the end products work flow.
It is for that reason that a package written to generate a fast accurate
bitstream, has difficulty implementing such things as encoders. To implement
an encoder properly, I suspect, takes a design more geared toward variable
control of a motors velocity (EMC) rather than a program concentrating on
constant control of a computers timing (Master5). The two philosophies are
really quite different, though that might be hard to understand unless
you've been initiated into the voodoo coding of real time programing under
windoze. I think I may opt for a completely separate version for encoders.
I hope in time, to bring it all together. Perhaps in version 342.5.

Thanks for the info and the insights.

PS. Thanks for hint Ballendo, DXF imports now allow for USER SELECTABLE
toolpath optimization.
