Hi JP - control Fanuc Oi MC I changed the parameter 5008 and the program ran well, thanks for the info. This issue has cost me thousands on a mould insert that had to be scrapped Just wondering though if it will come back to bite me in another way down the track? Has anyone encountered errors or crashes after changing Bit 5 (QCR) to one?

This is a work in progress. These alpha controls are dumbed down fanuc 21t controls for teach harrison lathes pre 1999. They accept G code no problem however they need sets of information in the correct order to operate, ( the sets - 2 per tool change) I have got the post to a level where I can operate single tool programs with very little editing but it still needs work. For example #509= 1 value must increment +1 every time #509 is encountered IF[531EQ1]GOTO502 must change to IF[531EQ2]GOTO503 at end of each set.(2 sets per tool change) needs to update EQ and GOTO by one each time I would appreciate any help with this O0001 (AZ T001) IF[#530EQ1]GOTO#529 IF[#1000EQ1]GOTO[#509*10] IF[#1001EQ1]GOTO[#509*10] N10 #501=1 1st set #502=12 tool number - works ok #503= X20. xh$ must not show X just 20. #504= Z60. zh$ must not show Y just 60. #507=1 #509=1 increments each set by one (not each tool change) #510=F must show just .2 etc- not F... can only get rapid feed here with fr$ must not be reading 1001 yet?

I agree with dannysdad, it would be great if you could just select a tap icon like the drill one , I find that I change the drill program to tap and then next time I want to drill a hole its defaulted to tap and visa versa. Hopefully this is something Mastertcam can look at because really the less etting that have to be changed on each operation make our lives easier
