An example might be helpful. The set up instructions recommend a spoil board of say 18mm hardboard. This reduces your max height from 88 (from the machine bed) to 70. Also deduct any "gap" height above the workpiece I use 5mm. So the maximum thickness of material in this case would be 65mm. Setting a value above 65 would give you an out of limits error.

Trying to decide between a T-track system or the pronged tee nuts. The frame/base of the machine makes it difficult to attach the T Track to the spoil board without losing height from the Z axis. Any thoughts on which system is better in the long run?
