@Bruce Layne, who did you get those spindles from? If the alibaba poster doesn't want to give a quote for 1 item, then why would they put 1-xxx amount on their listing? My rfq was over the minimum quote amount on each quote request.
I am not going to spend $3000 on an atc right now, I have been thinking that an automatic Z zero would take about 3/4 of the work out of tool changes.
