great!!
these things can take a beating over the road... they're exposed to forces they'll never encounter in operation. i'm actually writing up a 'receiving' document and stuff like this will be covered- test runs, ect- to ensure all is well.
it may have been your gantry the whole time, but, i'd hate to have offered that up and it been the alignment all the while- and because that compounds problems with variables that can throw folks for a loop when trying to diagnose an issue later on...
when it's all said and done, these machines are simple. they're built like dang tanks and perform as well as any anywhere on the market regardless of cost, but they're simple. simple is better, by my reckoning.
