Greetings all; 1) With a usb extension cable between the radio buttons on the hub, I was able to collect around 200 megabytes of noise withe usbmon directed to a file. Moved the radio buttons for both keyboard and mouse from the extension and hub, to plugged into the pi, did not check mouse range, but with the pi mounted on the door of the box, and the door open, I suspect the keyboard signal was probably bouncing off the closed garage door to get from the keyboard to the button. However at 26 or so air feet, the keyboard still worked quite well. I didn't check the mouse range as the pointer is too small to see at that range.
2) watching usb, you see EVERYTHING since the ethernet port is effectively a plugged in usb to ethernet adaptor, so mixed in with the keyboard and mouse noise, you also see the every few seconds cups updating its available printers database. In plain text even. 3) jog-inputs are apparently not subject the the max speed slider. I found this out when I had the jog increment or jog-step-size set for 20 thousandths. I could easily over run the axis, but that gave the slow display time to tell me it was moving at 105 IPM once it had reached cruise velocity, while the slider was set at 36. And of course at the first bat of a gnats eyelash, it stalled as thats faster that it can do w/o stalling. This I consider is a bug. But can it be fixed easily? Or am I configured wrong to start with? Yes, I see if I convert those figures to inches, I have many times the steady state run velocity the axis is capable of programmed into Z, and probably X too but x is busy clamping a felt wiper in place on the rear of the crossfeed carriage, for a few hours yet so its not been checked for non-compliance. I know Z can run pretty reliably at 90 ipm, so I'll set that as MAX_VEL to 1.5 in joint1, and scale trajectory down to 45 ipm since I am using some backlash comp. Progress. Back later.
