Wanted to ask, though - can you tell me or direct me to an explanation of why the X5 prompts you to sell an existing RAMPS setup? I know the X5 is cheaper, but beyond that I am just curious about it, no other agenda. I see that, as well as others like a Melzi that looks significantly cheaper, but I have no experience or idea about all the consequences of such a choice.
My Megatronics 2.0 with GLCD (single-board with same electronics as Mega2560/RAMPS) seems to be at the limit of CPU performance driving a Delta. Even printing from the on-board SD card, it will pause or slow down momentarily every minute or so like it is catching its breath. Forget about any hopes of doing 1/32 stepping. The Melzi uses a A1284P CPU, which is also an 8-bit processor and most likely also operating at the redline on a Delta. I'm with Jay in needing to move on from the current generation of controllers. I had put my eggs in the RAMPS-FD (Due-based CPU) basket, but with the departure of bobc from this forum and uncertain future of RAMPS-FD, I gave up on waiting and ordered an X5 over the weekend as my next step.....
