Brilliant thats going to make life a lot easier! any idea on how mach synchs the steps i.e if in psuedo code i ask it to go 20 steps cwise x axis then 10 acwise y axis how does mach calculate when the 20 x axis steps are completed is it open loop time based or does it have a count signal from encoder or a completed signal from driver board?

really appreciate the help

Hi all, Ive been tasked with a current project that requires some dc servo control and mach seems like a good option for control how ever i have a few questions, this wont be a 'standard' machining use and as such everythings having to be designed from scratch. The majority of the work is done but im wondering about mach's protocols  (this may be silly as ive not had anything to do with cnc software before) i.e when mach outputs a number of pulses coresponding to encoder counts does it pause for a set time while the action is carried out or does the driver board give mach a sequence completed signal so it can send the next steps? and is there a pinout anywere for the parrallel port connection and machs uses for each pin? Ive tried some of the pdfs but cant seem to find anything?
