Hello! I am now trying to set the machine up and getting the only axis position itself according to a "scale" widget is what I am trying to achieve.
The HAL setup is as follows: 1) there is scale widget in pyvcp with initval = 0; 2) there is a kinematics module, derived from trivkins, I only added a pin, named "offset" and these 2 formulas: joints[0] = tran.pos->x + offset; tran.pos->x = joints[0] - offset; 3) scale output is connected to the kins.offset input. The thing is that, as I slide the "scale" widget: 1) joint[0] position does not change axis.0.motor-pos-cmd does not change axis.0.joint-pos-cmd motor does not move 2) X axis position changes! the cone in the preview moves the numbers in DRO change halui.axis.0.pos-commanded change its value I tried both KINEMATICS_IDENTITY and KINEMATICS_BOTH, as I thought that only "one way" calculations can cause some error, but that turned out to be wrong and not improve the situation. What am I missing here to make it work correctly? All the previous times I did something like this in kinematics, it always worked as intended, but now it is all opposite - scale widget seems to change X axis position instead of joint position. Homing that axis does not improve the situation. It is obvious that axis.0.joint-pos-cmd and halui.axis.0.pos-commanded have different "sources" of the numbers they show. Why is it so? Can anyone help my out with some light in this dark corner?
