Yes, n_step should be by definition > 1, but ...

'ts' : ('ts.simple', {
't0' : 0.0,
't1' : 1.0,
'dt' : None,
'n_step' : 1
}),

I've reopened this issue just to query the first step output. I've noticed
that the first step (even for multiple steps) always outputs zero's - is
this a pre load/displacement condition?

This doesn't make sense if there is only one step since nothing gets output
and seems to be a waste with more than 1 step.

hmm - thinking about it - my t0 is always 0, hence no output - so probably
a non-issue.

Well, you should get the output file, and it should contain your initial
condition.

If you want to get a quasistatic solution at the step 0 instead, add

'quasistatic' : True,

to the time solver options. I have fixed some errors just now, so get the
latest version.
