Once again can you please offer up the version of Linuxcnc,the underlying OS and whether you are using a parallel port based system with software step generation or you are using a hardware based solution, once again any config files will be helpful.
Call me what you want I really don't mind, as you don't know me personally it hasn't affect .
In my dealings with PCW I have found him to be very generous with his time, knowledge and the schematics related to his products. Like I said read the forums and pay attention to the advice, help and response to custom FPGA bitfiles for his line of Mesa products, you will find everything I said to be truthful representation of the facts.
If you require help we're here to help, if you want to argue I gladly indulge that as well. If you bear false witness regarding members of this forum I will refute any statements that do not truthfully represent their character.
In saying all that I feel this thread would be better off deleted as it is proving to be a tit for tat affair.
Mayhaps then you could start a new thread and we can forget about the whole MEM thing which isn't a "Linuxcnc concept" as per the standard codebase. If this was a feature the various GUI would have that button, Hal pins would be exposed for that feature and it would be documented.
The closet feature would be the "reload button" but that rereads the file from the filesystem, but will also use the the original filename with any changes that may have been made. Which when combined from the "run from here" feature is a useful way to add extra code to a file without having a complete rerun.
Once again, the I formation requested regarding your system will be most helpful.
I would like to request if this information isn't supplied that either the thread is locked or deleted.
