Intro Spex uses 2 SM34205D smart motors. In 2024-05 a spex smart motor was replace by a spare. A new spare was purchased. These notes are on setting up the new spare. In order to use the smart motor on spex, a program must be loaded into the animatics motor. This program is located at /home/s2/src/spex/ldog/sm_wheel_home.sms. Original motor were: SM34205d, Firmware: 5.0.3.41 New spare label says: SM34205d, FW Version 5.0.4.69 Only the motor was purchased. Used a old power supply (hilo lab), and cable (summit) from spex. I had my own usb-to-serial adapter. Downloaded SMI_3_0_0_81.msi from animatics.com (saved in vendors_info/animatics/) Installed on PC. Test Motor using SMI terminal Once plugged in and power up, I was able to test communication using the SMI Terminal window on COM3: Report the motor position: RPA 698 Report the assigned current: RAMPS 1023 RSP - report sampiling rate and firware version "12500/5.0.3.41" for spex's 34205D, so 0.000125 or 8000Hz Commands I used to move the motor: ZS ' clear all errors O=0 ' set origin AMPS=200 VT=5000 ADT=100 ' set current limit, Velocity, and acceleration Set absolute Target position, and Go: MP PT=8000 G ' should move about 1 revolution PT=0 G ' returns to start OFF ' turns off the servo. Program the motor for spex /home/s2/src/spex/ldog/sm_wheel_home.sms is the program file for the smartmotor. Copy the program to your PC. Using the SMI program, File->Open to open the .sms file. Using the toolbar, select the download icon to download the program. After, I check things by power off/on the motor. Then used the "upload" icon to see the program loaded in the motor.
