Hi m_c, the Kflop is great isn't it:)
I may ask you about limit switches with the Kflop, as no doubt you have done it. I would like to use IO0 to IO4 on the JP7 connector, but I've never done this. I will reserve the question for later on, one thing at a time:)

Regarding the EM drive, it's not particularly noisy, just the usual little buzz that some drives emit on standstill, which can get annoying over time. Yes, I tried the dip switch4 down and up. I did the same with the AM882 which I have on the other axis, identical setting and motor, but this one doesn't make any noise. I seem to remember I have the little yellow selector wheel with the arrow on 4 which selects a particular Leadshine motor and applies relevant parameters. I may try and set the wheel to something else and see what happens.
