Dean; Personally - my location makes my situation different than yours.
I have 3 CNC builds - two with Gecko 540s, one with Leadshine stepper drivers ordered from China. Ok - of the Gecko G540 machines; one is Mesa 5i25 driven, the other is software stepping. The 5i25/G540 really works VERY well. It did take a bit of asking questions to get the HAL files ok, but chalk that one up to learning. The Leadshine drivers (with Mesa 5i25/7i76) is very good. The stepper motors are quiet, while the G540 driven steppers have a strange white noise/humming on both machines when idle. This machine appears to be the way to go. I lost a G540 driver earlier this week; on the "A" axis on a lathe that had only the X and Z axes wired in. Ie, there was no load on it, but it smoked anyway. I don't know if I'll bother ordering a replacement driver module for it. The G540 has a max input voltage of something around 48v, while the Leadshine drivers I got go up to, I believe, 80volts but check. If correct it means you can keep your original power supply. My location situation? Being in Canada, while I want to support my brothers/sisters in the USA, it's cheaper to order in from China, especially with the recent devaluation of the Canadian dollar. You may find that the Leadshine stepper drivers are actually name-badged from the old Keiling site - AutomationDirect, I think it is called now. Hope this helps. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
