Hi all
I seem to be having a problem with my ez board. This all started when i decided to upgrade my router machine. After building my new machine and starting the setup i am getting some kind of power cycle or other problem with the ez board. Everything will run fine for about 5 to 10 min then everything will stop with a loud whine from the steppers. It will then start back up again but it is not running right, before the power cycle i am reading 0.4v off the test points for the driver current after the cycle i am getting 0.3v or less. Also after the cycle I am only reading 3v at the 5v test pad If I turn off the machine power and wait a few min everything will come back normal and start the problem over again.
My build consists of: Hobbycnc EZ board, 2ea Nema 23-305 and 1ea Nema 23-425 stepper motors operating in unipolar config. I am using belts on the X and Y and a lead screw on my Z. I ran 18awg shielded cable for all motors with an average run of about 12 feet. I am using Linux cnc for control software. I was originally suspecting a power supply problem and have tried two different Mean Well LRS-350-24 supplies and also my original 24v transformer/rectifier/cap power supply, all with the same problems
Thank you for any help
