Thank you for thinking with me! Colin, I tried your version, works the same as always. Posts the break detect to previous tool. I got it sorted actually. ptoolend$ #End of tool path, before reading new tool data !speed, !spdir2 if mi7$ = 1, [coolant$ = zero n$, pscool, e$ n$, "G112", "(BREAK DETECT)" e$ # Tool break detection "G112" ] This posts the break detect to the required toolpath end, where it should be. It's working fine, stops coolant, checks the tool. Now, when i apply this in the middle of working, when it's not the last toolpath with this tool, then it posts G112 to the end of that toolpath *first toolpath end N1240 G0 Z5.

Is it possible to start the spindle again? I have got the spindle started again - just toggle pspeed and pspindle and i'm fine, but when done so, it starts the spindle again and then goes for toolchange if the last operation is checked. This is really frustrating when spindle is speed up to 15k rpms and then stopped again for toolchange. Thank you for your help!

Added that comma, nothing is better. I'm using Mastercam X9 and Okuma Generic 4X post. I have tried to add the misc to every operation by the same tool, nothing happens. Only single operation done by one tool seems to work. Like drilling, but it also has it's tweeks, when applyed to drilling, then G112 is on the drill toolpath end and previous tool toolpath end. Tryed mi$ and mr$, both act the same.

Hello, I'm trying to use Misc Values to create a line that, when added to toolpath, checks for tool break and pullout. I have recently dealed with Misc values and all of my other modifications work fine, but now i'm clueless. I have added a line to the post: if mi7$ = 1, n$ "G112", e$ pretract #End of tool path, toolchange sav_coolant = coolant$ coolant$ = zero # if nextop$ = 1003, #Uncomment this line to leave coolant on until eof unless # [ # explicitely turned off through a canned text edit if all_cool_off, [ #all coolant off with a single off code here if coolant_on, pbld, n$, sall_cool_off, e$ coolant_on = zero ] else, [ local_int = zero coolantx = zero while local_int < 20 & coolant_on > 0, [ coolantx = and(2^local_int, coolant_on) local_int = local_int + one if coolantx > zero, [ coolantx = local_int pbld, n$, scoolantx, e$ ] coolantx = zero ] coolant_on = zero ] # ] #cc_pos is reset in the toolchange here #cc_pos$ = zero gcode$ = zero pbld, n$, sccomp, *sm05, psub_end_mny, e$ pbld, n$, scoolant, e$ pbld, n$, sgabsinc, sgcode, "G53", "Z400.", e$ if mi7$ = 1, n$ "G112", e$ coolant$ = sav_coolant This is the part where the tool check should be active, just before next tool and toolchange. But there is a small problem. When I add the misc value to some operation (the last done by the tool i want to check), then in some cases it displays my G112 and sometimes it is just in a very wrong place. Lets say I want to check T26, next is T5 and after that comes T11, then applying G112 to T26 it somehow goes to the end of T11, so it is very random in some cases. I know that this is more less the place that this G112 should be, but why is it not with the right tool or not displaying at all...? Maybe you guys can help me out - or offer a more common solution to get the tool to check itself. I know that Manual Entry is there, but we like Misc values more and I would want to learn about post edit some more. Thank you!

I guess i was ahead of myself... Got the G116 working - just needed to select the .LIB file, change the buffer size bigger and now it works like a charm. At first i understood that i can just make some changes to my LIB file, save it, restart the machine and we are good to go... Not so simple. Or maybe even simpler. I had to reload the LIB file - at first i didn't find the place to do it. and write the lib program name to parameters. Now we're good to go. Here is the G116 that i used.

Helloo, I'm new to this forum, but i have got alot of good info from here so thank you all! Now i'm facing a problem that our Okuma M560 with OSP-P300 and it's .LIB file... I wanted to add G116 logic to our machine that controls the toolchange that we dont have to manually enter M64 each time wrong tool is prepared and we want to start a program. We are getting the 5223 error that says buffer overflow... We are using .lib file that allready has tool measurement macros in it and if i increase the size of the file by adding just a coupe of lines, then we get this error... So my question is. Is there a way to increase buffer size (at the moment its only 5Kb?) or can i rewrite the .lib file that it is selecting automatically a smaller program that contains CALL or GOTO-s to another program in MD1 directory? Thanks for your help!
