Some suggestions

1 How to fix the WeMacro rail.

Please consider our Vertical stand which can save space on the desk and can also work in horizontal position.


2 What ‘s the difference about 2 mode

It’s my personal opinion that.Below 5X or 5X  magnification,you can use from start to end mode.It’s quite  intuitive.But if shoot in bigger magnification,it will be better working in distance mode.Such as 20X for butterfly wing scales.You can move the rail forward to get close to the beginning point.Then set a distance to run.At the end of shooting,if you are not sure whether the distance is enough for the whole range,and you do not know what the last picture status is,you can simply press “shutter” to shoot one more picture to check.Also it’s better changing parameters on the camera by cable or wireless instead of operating on the camera.

3 When I should use lens support

The are two methods to support lens.Nylon blot and ring support. These work when you shoot in continuous light.They can help to reduce the shake caused by the mirror.By using this method,you can reduce 3-5 seconds to stable  the picture.It can save a lot of time when a stack contain over 100 pictures.

4 Why WeMacro rail has three hole in camera’s position

Of course, most cameras be installed in the middle, Because of the slim base, you can change battery without taking the camera off. And you can set  camera in side to adjust  for battery changing.

The picture shows you can open the battery holder without taking the camera off.It will help  if you have a lot to shoot.

In second page you can adjust the position to close to the starting point.If you feel too slow to adjust in micron mode,you can return to first page,swtich to mm mode.But please remember to change back before fine adjustment.To get better accuracy,if you press backward or stepbackward in adjusting positon,please make forward or stepforward,length should be longer than 180um,about 1/4 rotation.So we suggest slowly go forward or step forward  to approach the starting point.You view it on camera’s LCD or by using EOS utility,helicon remote or nikon camera control pro on PC.But remember to turn off live view on camera or PC software,before start shooting.

The ”stop” button need to be pressed to switch to ”run” when it finish running.

Notice:The shutter signal may not work if you are controlling the camera through a USB cable on PC by camera software such as Canon’s EOS utility or Nikon’s CameraControlPro.Turn off live view function in software can make trigger signal from control box works.Also set the camera at M mode and the lens is MF mode too.
