There are potentially 10,000 things that can cause length variation. You have not provided any information as to what you have done, what you tried, how your are controlling synchronization or any other piece of useful information. However, most problems in length come from the measuring wheel. Also, what parameters are you using? What is your maximum line speed? How long is your synchronization length? What is your maximum acceleration rate? Are you using Jerk limitation? As for encoders, I use 2000ppr. What is more important is to calculate from your measuring wheel diameter how many pulses per millimeter you are generating. Keep in mind that the pulses from the encoder are sensed on rising and falling edges, so your pulse count is actually 4 times higher. Some of mine for reference. We use a belt too on our small saws. https://www.youtube.com/watch?v=uhAGzth68FM https://www.youtube.com/watch?v=ZSwl-U5_Qa4 |

My pickup truck has a flat tire. Could someone please give me a step-by-step instruction on how to exchange a tire. My programming buddy Liam and I want to do this later today. See the photo of my pickup truck: http://www.tire-information-world.com/image-files/400xNxliebherrt282b-2.jpg.pagespeed.ic.AxWs7tyGMM.jpg Hello Humam. If you followed the link to the photo, you will understand the point I am making. I suggest that you get someone that knows these systems well to get the job done. Without intimate knowledge of your system and unknown what your own know-how background is, it is almost impossible to help over text messages. Sorry for the opinion. - Dan |
