Hello,I am assembling my X Carve 1000.I am at my third microswitch and seem to be short one tiny lock washer.M2 stainless 30555-03.Will I be able to continue assembly and come back later and add the lockwasher? Thanks…Scott

If by the 3rd one you mean the one for the Z axis then yes you should be fine. If it is the X or Y, these are more difficult to do after the machine is completely assembled.
