Just moved machine into shop a couple weeks ago. Was having some issues with tool change and home position. Machine came with low batteries and was getting alarm for that, think it was ATC battery alarm. Batteries finally arrived and I changed them out with power still on. Went to home machine and got Y and Z home alarms, went to partameter 1815 and 4bit was 0 instead of 1 on both of those. went thru procedure to change to 1 and was able to get all axis home. now on to do a tool change, was going fine until arm change and looks like Y is out about an inch or so. moved back arm and now getting a MILLING SPINDLE POSITION ERROR #2140. Can't find info on how to clear this now...
