Hello RepRap
First, the problem. I am having a hangup after I uploaded the latest Marlin. When I try to connect via Pronterface, the Mega blinks 3 times, but all Pronterface shows is 'Connecting...' and does not budge. Or hasn't for the last 5 minutes. I also tried in Simply 3D's Machine Control Panel that tried plain text, binary, and alternative communication protocols that all didn't work.
This is a Mega that I have been using for over a year now and have been happy with.
About me and background, long time user, but first time back into the thick of getting it to work. I have experiences with a Mendel and a Huxley, then moved onto a delta (Blue Eagle Labs Kossel Clear) and am now happy with a Blue Eagle Labs Metal V2 that I got through the beta. However, I do not think Blue Eagle Labs is still functional.
I was working on the printer and wanted to do a very large high detail model on a gcode over 250MB in size and 90 hours long. This was so large that the computer would crash after 8 hours or so on the three tests I did. I knew I needed to get the SD card running on this delta. I had it running on my Mendle for some 48 hour prints, but this needed to run on the Delta for the larger bed size. I decided to scrap the old Marlin and install a fresh new Marlin with all the parameters transferred over. I transferred it over and.... no luck. I can't connect to it in Pronterface again, but I can in Arduino.
Also, it seems that Arduino cannot compile my old Marlin Delta firmware.
