I have a general question about the throughput of EMC2 and what determines it. I friend is using nurb modeling to describe the shapes that he has to mill in soft material. So far he has had disappointing results using EMC2 in that the processing of the large gcode files with many short vectors and the resulting cutting speed is too low. For most cutting moves the programmed speed of the axes is not reached in these applications. Jogging speeds on the machine is fine. Where does the problem lie?
In playing with parameters such as base_thread, we found that these have some influence on the troughput and cutting speed. The processing power and latency of the PC also comes into play. It seems that careful tuning and balancing of some parameters is required. The problem is to know which ones will improve the situation best. The steppers are currently driven via the parallel ports. A MESA 5i20 card is planned to replace this. Has anybody been working on the limited throughput situation?
