Hello, I try to read a printer test chart with a Colormunki Photo. I'm not sure if I'm doing things right as I do not get any result. I let the instrument read the strip and press "d" for done. The chartread answer : "Done ? - At least one unread patch (A1), Are you sure [y/n]:". Finally I tried "y" to see if I can get strip B. I got : "munki_simulate_event: terminate switch thread failed, canceling I/O" I tried multiple ways to read the chart. Nothing works and I've read the Argyll doc about strip reading for the hardware I'm using. I'm not comfortable in the way I'm doing it. I can see the LED in action at connecting but not after. - start measurements with press enter key, - start measurements with the instrument button, - on the white part of the chart, - on the first patch, - quicker and slower. Maybe I'm doing something wrong. Thank You. ~$ apt-cache show argyll Package: argyll Version: 1.5.1-3 Debian testing (Jessie) ~$ chartread -v -D printerA Steps in each Pass = 14 Passes in each Strip = 7, 7, 7, 7, 7, 7, 7, 7 Instrument Type: ColorMunki Serial Number: 2016629 Firmware version: 288 Chip ID: 01-4B7336120000D7 Version string: 'colormunki FW V1.32 Build Nr. 1303' Calibration Ver.: 6 Production No.: 28918 inst_handle_calibrate called About to call calibrate at top of loop Calibrate returned calt 0x60, calc 0x60, ev 0x127a Set instrument sensor to calibration position, and then hit any key to continue, or hit Esc or Q to abort: About to call calibrate at top of loop Calibrate returned calt 0x0, calc 0x60, ev 0x0 Calibration complete inst_handle_calibrate done 0x0 Ready to read strip pass A Press 'f' to move forward, 'b' to move back, 'n' for next unread, 'd' when done, Esc or 'q' to quit without saving.
