I've noticed these issues for some time and just ignored (lived with) them, but I wonder if they are configuration problems or bugs related to World/Joint Mode. Weird, weird, but repeatable problems...
If I start Axis and bring it out of estop and turn it on, then select World mode and wait, say 45 seconds and try to jog, I get nothing. It is as if the window has lost focus. I haven't moved off the window at all. If I click within the window itself (not on the title bar but somewhere within it), nothing changes, I still can't jog. However, if I click on the blue title bar at the top of the Axis window I can then jog. This only seems to happen after first starting Axis. Once clicking on the bar is done it doesn't happen again. It also doesn't seem to happen unless I delay the 45 seconds (or so) before doing anything. And even more disturbing (and ignoring the issue above): If I home the gantry Y axis first thing after starting Axis, all is well. If, however, the Y axis is not where I want it, I select World Mode, jog to the location I want, go into Joint Mode, and then home the Y axis. At same instant I press the Home button Joint 0 (but NOT Joint 1) jerks [in the direction I was just jogging] a small amount. The DRO indicates a position, let's say is it 0.1. If I then unhome nothing happens. I then home again and again there is jerk and Joint 0 actually moves back or forward (I can see/measure it) but the DRO is still showing 0.1. The amount of the jump is different each time I stop/start Axis (0.0094, 0.0055, 0.118, 0.0362 are some measured values). Also, I can predict how much it will jump because: 1) I start Axis and bring it out of Estop. I notice that the DRO shows for example, 1: -1.0179 2) Click On button, nothing changes 3) Selet World Mode, and notice that DRO now shows 1: -1.0049 4) I note that the difference between these is 0.0130 Sure enough the distance of the Joint 0 jerk movement is 0.0130 I have been (for months) trying to make sure I don't jog before homing but this is really annoying. What could be going on? And FWIW, I am running gantrykins. In kinematics.hal I have: setp gantrykins.joint-0 0 #0 = X setp gantrykins.joint-1 1 #1 = Y1 setp gantrykins.joint-2 2 #2 = Z setp gantrykins.joint-3 1 #3 = Y2 In my .hal file I have: ...
