Given the requirement that it match the extruder nozzle height to within 0.05 mm (more or less) over a wide temperature range, it's a *very* tough problem. I think separating the nozzle height measurement from the platform probe operation might be the only way to make both of them work properly. I put a simple switch on my much-modified Thing-O-Matic's platform and poked it with the extruder nozzle to set the zero height position, but that's obviously a poor general solution: http://softsolder.com/2011/05/18/thing-o-matic-z-minimum-platform-height-switch/ Those platform pictures come from the days of ABS slurry on Planet Barbie... [wince] I think a pogo test pin with a side flag tripping an optical interrupter, perhaps through an amplifying lever, might be workable for platform probing, but I won't believe it until I run the numbers. -- Ed softsolder.com ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
