You should make your choice NOW about going steppers or servo's. I personally will always go with Servo's and a G320's from Geckodrive. If you read the router posts then you must have seen mine. My router is 24" X 24" powered by my servo's I sell. I did a real world test with my router a few nights ago. I wanted to know how strong my servo's were. I did not have any measuring equipment but my cousin who is a large and strong guy leaned his weight and muscle on the Y axis to prevent it from moving. He could NOT stop it. He said he knows he put over 100 pounds on that. He said it would have crushed him if he was in the path. I am getting over 150 IPM and have plenty of strength.
