This is just my opinion, but to me 130 Watts is way too small, especially with a router where you might need extra feed rate when cutting wood. My mill has 350 Watt steppers but it doesn't need to go very fast, and doesn't. I would feel better with 500 Watt, 90 Volt motors. > The controller is a step and direction type, with the encoder feedback > passed back through to linuxcnc via a mesa 5i25 and a 7i86s..

An advantage of having the PID loop in LinuxCNC is that you can use HALscope to monitor the PID parameters to see if the output command is getting saturated or hitting the load limit. It might be useful to see if you can get the drive to tell you how hard it is working. Hmmm... I just looked at the drive information: http://www.americanmotiontech.com/Products/ProductDetail.aspx?category=4&model=ACS806 I would max out the drive voltage to the specified max. of 80 Volts if you haven't done so. It also looks like there is a serial port on the drive which you might monitor with LinuxCNC or with the tuning software that comes with the drive. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
