Calling sub programs and Mirroring in ShopMill

[@arresonance]

When working with subprograms that happen on a sub spindle on a lathe (so G55 mirrored) they cannot be simulated as the 828D can’t handle tools: they are perceived as facing the wrong direction. My hunch is that when a sub program is simulated it expects it to be something happening on the main spindle (as this is the whole mirroring concept works, I think). The only workaround I found it to manually edit the .MPF in a text editor to change the very first long number after the parenthesis. This seems to be the “checksum” number that tells the control the sub program has been simulated. I would like to discuss this problem with you if possible. Thanks!

With all the frustration I probably would have switched to Autocad, draw the dimensions, save as a DXF, then use path mill. 10 minutes.. Thank you for video though. Learned alot.

Thanks

For some reason our Skoda Machine 840D sl don't want to call subprograms from anywhere except NC (stored on NC in standart subs folder and in the same folder as main program in Lxx format). Otherwise displays something like "name undefined".

There is some problem with sound :(

[@MrCNC]

does sound work now?

[@numbsliwa]

@@MrCNC I have to check. Beacuse there were moments where your voice was cut off.

@@MrCNC I don't know if it's a matter of the fact that you don't say anything then, or that the sound cut off but, for example, you cant hear anything in 21:30

Can you show how to R-loop with G code? I know that ive had to mail you sir with question about looping but it was a different case. Im struggling with looping with R commands (While, Endwhile, If, Z=R1, X=R2, R1=R1-0.25etc).

@@MrCNC are there any chance for a video showing hov to work with these kind of loops?

[@numbsliwa]

@@MrCNC By the way. Your channel is really helpfull for me. I learned some usable things from it or learned things that I didn't know could be done. Its a real mine of knowledge :)
