General Mach Discussion / Re: Mach 3 Driver test. Results for 3 computers, which is best? (PICS)
« on: March 23, 2011, 07:42:22 AM »
Yes, the 1st computer i plan on using. It is the newest and has the lowest maximum variation it seems like. The highest max variation i have seen it reach is 2 US. I will have to strip the computer down and see how clean i can get it running. I assume lower uS is always better. (i had about 23 processes in the background running in windows XP pro).
I have been a new active user over on the smooth stepper forum. I did see the new plugin that Greg has come out with! Pretty cool stuff! He has worked really hard on getting it up and running.
I have never ran my cnc machine without the smooth stepper so it will be interesting to see the outcome. I would like to bypass the SS temporarily, eliminating any extra realms a problem could be created. The smooth stepper has not given me a single problem at all and has been a joy to use. My viper drives can only accept a 125Khz signa (max)l. Mach 3 can only output 100Khz through the parallel port. So i am getting an extra 25Khz by implementing it (SS) over the parallel port. My machine uses servos, and the rapids are already scary fast (for me). I figure if i use the parallel port @ 100Khz i will be down 20% in speed from the smooth stepper. My max jogging speed is 500ipm, and 800ipm (X,Y). If those get cut down 20% i can't complain since i will be rarely flying around at those speeds (worse case scenario, i haven't tested what my MAX speed is even @ 125khz and im still getting scary fast rapids so im doing well.)
For the time being i was just want to cut out any unnecessary things between the controller and machine. This way i will hopefully be able to find and address problems faster. I currently dont need USB, or 125Khz. I can live with 100Khz and the parallel port until i get a feel for the machine. (its a new machine, and im a noob).
By the time i get a feel for how it runs and what its doing, i can convert back over to the smooth stepper. By then im sure more people will have tested out the new driver and backlash plugin, furthering its success.
