the lathe i am using is a binns and berry with a fagor 8025ts controller
i new there was something wrong with the system as when you press the x+ on the controller the slide moves in x- out(programing x+ moves in the right direction i think its for a rear toolpost and mine is a front) the hand wheel moves in the right direction my main problem is using a g68 canned cycle it will rough out alright (with g02 and g03) but error comes up on final pass so the p7 line i put in 0 so no final pass and wrote a separate final pass and i noticed that the g02 line was doing a g03 and vice versa so i changed my g02s to go3 and it worked
i can only think the machine is set up for a rear toolpost but i dont understand how the roughing cycle is alright

I just had to reload the parameters in a 8025 and recall that there are parameters that control the sign of axis movement including I think jog mode.

To get to the parameters, use op mode 9, general parameters. You'll need to look up which one controls jog in your manual.

cheers captdave i will try that on monday.we also have a problem with cutting threads, it seems to cut the wrong pitch , there are parameters for error compensating but i find the instructions not very user friendly

Try this also, I happened on this today.

Reversing the G02 and G03 directions
When changing axis direction the interpolation direction changes,
this requires parameter P600 bit 1 to be changed.
If the machine runs the G02 and G03 in the wrong direction, change this parameter.
P600=0000001 change to P600=00000000
P600=0000000 change to P600=00000001

As always write down your current values prior to making any changes:nono::nono:

Cheers got the the control button on the consul to go in right direction pressing x+ now goes + .The line p600 for(g03 reversal) on my machine is 11100000 not 0000001 so i was reluctant to change it,the only line i could find with 0000001 was line p608 and i cant find anything in my manual about it the manual i have is cnc 8025t oem is this the correct manual
