With good reason. Microsteps can only ever be an integer, and is normally a power of 2 as well. > the data for my drive say pulse ,dir with no > spec for dir hold or space. With a typical stepconf setup, and any hand-coded setup using "Reset" the step-space will be what is left over after making the pulse, and will be more than adequate. It is also very unlikely that you will have any problems with dir setup and hold timings. > These seem to run pretty slow for me im running > a 24 v supply would 48 be better? Higher voltage will always give higher maximum speed with steppers. But the drives have to be able to take it. > also im running a 2.8 intel duocore w/2 > gig is this os 64 bit ready? it seems to me that would make a difference in > latency having twice the throughput? Latency and performance are very different things. The project is dependent on the RTAI patches and the architectures and kernels they are available for. I don't think that includes an x86-64 at the moment. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
