I'm currently tining a small fast linear axis. It uses a DC servo, timing belt, and linear encoder. I'm using Axis. This is the Y axis of my machine.
It's basically working, but I have a few questions: 1) Is it possible to make Axis re-load the ini file, or do I need to exit and re-start Axis to do this? 2) I'm repeatedly doing the following MDI commands: g0y0 g0y8 while I take a plot with Halscope to monitor the results. Is it possible to assign these commands to function keys on the keyboard, or buttons on the GUI, so they are more convenient? 3) The Calibration tool shows three tabs, one for each axis. For some reason, the 3 tabs do not show the same tuning variables for each axis. What is it that controls which tuning variables are shown in the Calibration tool tabs? 4) None of the tabs in the Calibration tool shows FF2 as a tunable parameter. To tune FF2, I shut down Axis, tweak the INI file manually, and then restart Axis. Am I missing something? 5) FF2 seems to have no effect. I added it in the INI file immediately after FF1. I've heard that it's very sensitive, and tried values from 0 up to 0.5, but on Halscope the error plot looks identical. As a reference point, my FF1 value is 0.25. My servo amp is a voltage amp (PWM input LMD18200 H Bridge), driving a small DC servo.
