Hey All, so I’m the unlucky guy who’s heatsink fell off and it managed to touch something it shouldn’t have frying the z stepper driver. So now I’m in the market for a new controller. I’ve done a decent level of research into boards, firmware, etc and have come down to two choices and was hoping to get some input before pulling the trigger:
Buy replacement RAMBo. This is the obvious first choice, it’s a simple drop in replacement, load the same firmware, and off I go printing the same quality as I have before. The downsides I’m currently weighing against it is that compared to similar feature set boards it’s more expensive. It’s also a fully integrated board, which as above if a driver fails, I have to replace the entire thing. Something I’ve never been fond and why I have never purchased an All-In-One PC either (laptops included).
Buy an Azteeg X3 w/ SD8825 stepper drivers. The highlights of this choice are the modular design making catastrophic failures like above easier to manage. Capable of higher 1/32 microstepping (YMMV on if this matters). Cheaper by far as the total cost would run almost $100 less than option 1. The downside would be getting the LCD on the TAZ 5 working with this board. It’s definitely doable but would take some firmware hacking and a bit of rewiring to get it up and running (90% confidence that I could do this in a weekend).
So anyone care to chime in?
