This is a tricky one. One lead longer doesn�t count after cutting prior to assembly, from the other choices the flat edge is the one I prefer. But real life hits, we found us trapped the same way. First: We made sure they were not mixed in the same b

We have both CP 4/2's and 4/3. We're also running Siemens S20's & F4's. The 4/3's vision is more temperamental and slightly harder to program. Machine startup and nozzle centering takes longer, but placement time is slightly better. Honestly, for wha
