All of this is important.Ordered
However there was no place to give the size of the scales needed, I sent them a memo with the order listing the actual travel on all three axis. I am not sure if I am supposed to make a deduction or addition to these specs????
Make sure that you actually measure the travel of all axes, not taking numbers from a spec sheet or ad.
The scales need to have more travel than the axes travel, or else you will crash into the end of the scales.
It is also a mounting issue because if you have 2mm of longer scale travel than axis travel, then the scale will have to be mounted very accurately within about plus or minus 1mm of where it will crash. That wastes time and is asking for trouble.
Too long is only a possible mounting issue or a possible issue of being in the way of other stuff. Pay attention to that before ordering.
I ordered my scales 1"+ longer than the actual axis travel. There were no obstruction issues. That gives plenty of room to easily find a place for the read head and scales to mount without fussy measuring.
It is very easy to measure the axis travel. Make sure no hard stops or other settings are reducing the maximum travel of the axis. Move the axis all the way to one end. Put a sharpie mark across where the two halves of the axis slide past each other. Move the axis all the way to the other end. Measure between the sharpie marks. Add, do not subtract, to make sure you have enough travel with your scales.
More questions?
