Allow soft limits to be disabled #13

Closed mark0n closed 9 years ago

mark0n commented 9 years ago

Set DHLM to "inf" and DLLM to "-inf" to skip configuration of soft limits.

Rationale: Here are some reasons why users might want to disable the soft limits:

  1. For single-axis systems soft limits can be specified inside the hard limits. This is not possible for multi-axis systems with more complex hard limits (e.g. not a simple switch but a pin touching some weird boundaries). In this case soft limits do not make sense.
  2. Systems that can be calibrated by the user in different ways (e.g. home position at 0 vs. home position at 10000) might not want to use soft limits.
