Hi everyone.
I bought this nema 34 stepper motor (https://www.oyostepper.es/category-9-b0-Motor-paso-a-paso-NEMA-34.html). It works great but I have two issues I can't figure out. When I enable it there is about a second delay before it actually starts. I know it's not the enable signal because I piggybacked some LEDs onto the input and it's instant. The second issue is that when I start or stop it the limits change about 1/8 turn. I was originally controlling it with a VB pgm on a laptop but then switched to one of those Nextion HMIs. I also ordered a programming cable for tuning the drive but it's from China so who knows when it will arrive.
One last thing to say. My main buck converter burned out and when it did it sent 60 VDC to the Arduino and the second buck converter but the second one burned out and turned off and didn't turn on so it looks like my Nextion is still good. So, I ordered a new buck converter, which should arrive next week.
If anyone has any ideas about the delay or set point change, I'd love to try it. Thanks.
