My machine starts a homing cycle after placement and then moves to the optical calibration point, and parks there. So after placement the heads stands over the pcb, making it a but tricky to get it out. Is there a setting to park the head in the park position? The settings provide a place where I can define a park position, but even when I check the "Parking position" checkmark the machine will remain on the optical calibration point. It does not move to a park position.
[Basic settings] 3.17 Parking Position The coordinate for the parking position can be set by X and Y and enabled by “Parking Position” check box. After axis-reset sequence or visual origin alignment the machine move to the parking position.
I found that, but it does not work.. After the job is done it starts a homing cycle, drives to the visual origin and aligns it. Then it stops there. It does not move to the parking coordinates. I check the checkbox and entered x and y coordinates for parking position.
I checked it with the latest software version, and after a job it still moves to the optical calibration point, very annoying. The parking position is not used. Would be very nice if that could be fixed.
That could be the problem, as the dot which is fixed on the machine is not reliably detected by the camera. It is a piece of pcb, but the copper is HAL coated, and it is not even, so I cannot detect a round dot. I often get an error on homing to the visual origin. I will try to change the dot to a better one, simple hole drilled in a PCB is the best. But I need to get it exactly on the same position. There are a few things you could do much better on these machines with small efforts..
I helped myself by grinding the point with fine grinding paper, now it is a dot again.
I found a program error: If you set a parking point and select that the parking position has to be used it throws an error after doing the visual origin. It says "Visual Origin Y coordinate exceeds limit" But it means, that the Y coordinate of the parking position exceeds the limit. I looked for an error in the visual coordinate, which was not there. As I changed the Y of parking position the error was gone.
I am currently working with the machine, it now drives to the parking position, but only now and then, 2 out of 3 boards it does a homing cycle but stays on the optical homing pint and does not drive to the parking position.
