Yes, that would work too. Thank you for pointing it out! Regards, Germano Zerbini GZ Programming Solutions

It is a permission problem while writing the buffer. Just specified where to save the buffer in the post using sbufname4$: sbufname4$ = "C:\Users\***your user name***\Documents\my mcam2019\Lathe\NCI\buf4.txt" *** your user name *** must be replaced with your username. Basically you are telling the post where to specifically save the buffer during the post processor run. I usually save the buffers in the NCI folder of the lathe or mill post in my mcamxxxx folder. Place sbufname4$ (where the 4 stands for the buffer number) right before the buffer definition (fbuf). Regards, Germano Zerbini GZ Programming Solutions

Jeremy, when you select the program to run, make sure to change the running method to 'B-Mtd'. See the attached PDF for the running methods differences and the image for the location of the Running Method field. This applies to the P200M and P300M (milling). I am still working on the lathe side...... RunningMethods-P200M.pdf

Jeremy, on Wednesday I am back in the office and I will work on this issue. Being new to Okuma world and having the privilege to work in the Application Engineering department, I will try to understand if the DNC is really the only way to read over 2MB files.
