Trying to get my machine up and running. I've gotten the power on and running for my system, all the stepper drivers light up and my fans are running, but it's extremely inconsistent when the system will actually turn on. Using my multimeter, power is definitely getting to the power source, but most (A lot!!!) of the time when I turn it on nothing happens. This is the power source I'm using: https://www.amazon.com/gp/product/B01E6S0JS4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Even when I had it running, I couldn't get my system to jog when trying with UGS. My next step is to troubleshoot all my motor connections, but that doesn't have anything to deal with my power inconsistencies. Has anyone seen something like this? Do I need a different power source maybe? It's 20A, more than enough for my requirements. My stepper drivers are seeing about ~1.8V when the fans and LED's aren't on, so not sure what's going on. There's some power, but clearly not enough? Anything would help. Thanks, Sam
I think I might have figured out the power supply issue. I went to toggle the 11V/220V switch and it broke loose. Pretty **** sure that is the connection issue I have been looking for. Contacting the supplier and trying to get a new one. I'll report back if this doesn't solve the issue.
Also, watch out for "LED Power supplies" - they look like switchmode PSUs but internally they do differ sometimes - either by design, or by cost cutting, and fail with inductive loads Consider a Meanwell (good brand, should not give you trouble, like 24V Meanwell Power Supply Bundle for example (and the extra PowerCase makes wiring easier and safer too)
Ya, I might just go for a better power supply. Maybe this LED one is causing my problems and a replacement won't solve anything. Will definitely be going with Meanwell instead of cheaping out this time. What's the difference between running a 12V and 24V power supply? My system is running off of an Arduino, TB6600 stepper drivers, and 4 NEMA 23's. The drivers accept between 9-42V, so I don't think it matters which size I choose? Any advice on this would be greatly appreciated. My fans are 12V at the moment, but would be cheap to replace if I switched to 24V.
Higher input voltage allows the chopper circuit inside the stepper driver to react faster leading to better acceleration, less heat and lower mosfet losses, less stalling and overall just better performance. Run the 12v fans off the LED PSU you already have then it doesnt go to waste (;
Haha I'll see if I can fit both of them in my enclosure. Ok, I'm gonna order a 24V Meanwell. Thanks for the info!
@Giarc I was actually thinking about putting them in series as well since I have two of them. I'll give it a shot since it worked for you, thanks!
