A guy on the tech support forums suggests that it could be phantom limit switches being triggered. Though I don't have limits enabled, it does fit with the "other axis will still work" weirdness. --- Quote from: Will_D on April 15, 2018, 05:58:57 AM --- I am starting to suffer this but only on the z axis. It will jog down but not up. Power off and wait resets it. I am running the [Install_2018-01-21_91] new 2.1 version. I may well go back to the stable 2017 version for 1.1 --- End quote --- When it freezes, do your other axis still work? |

I suspect its connected with probing! When Z+ stops working, if I do a probe Z+ it starts to probe DOWN at a stupidly slow rate! Its as if it thinks it has found the limit switch at Z+ and is now very very slowly coming off the micro-switch in the Z- direction ( as it should do fairly quickly) to the probe offset position (5mm in my case) HTH Will BTW the DoseDone forum has gone a bit quiet recently!!: http://www.ddcnc.com/forum.php?mod=forumdisplay&fid=41 |
