Steve, thanks! There are no changes to the timing or personality generators. Only the list above has been affected.
As for your question regarding locking a project to an EZB... Can you be more specific? I do not understand the question
Great to see more changes DJ i see you been very busy making a lot of great updates.
Thank you DJ 4 responding, I look forward and appreciate all of the new advacements of new EZB versions. We make such great strides with every new release. My question, would there be a way to save specific old robot projects, to a version of EZB prior to Release 2013.06.15.00 ? My old project would operate without modifications with the old version of EZB and I could advance my robot with new releases and modifications. I understand I would have to have muliple versions of ARC on my PC. The Bottom line is, I am delighted to have found EZ Robot, purchased such a great product, and built such an amazing new robot with my 2 EZ Robot kits. It is just an idea. Thank You, Steve S
Thanks for the kind words steve
The newer versions of the ARC software will not change your older project files. Also, a newer ARC project will work with older ARC also.
What kind of project modifications are you finding that need to be done when you upgrade?
