Hello
I build grbl cnc and I need little more power than drv8825 can offer. So I find TB6600 can offer wath i need ( I know they are not best quality but for my hobby cnc they work). and then i found one where are 4 of them build together. is this more relayable than the paralelport version of 4axis tb6560 boards. I know they are bretty bad I have one layng around.
