Recently had an issue where the E-stepper stopped working mid print and clogged the whole nozzle. Replaced all that jazz and then tested extruder to find the stepper wasn’t running even when sent G-Code (G1 E10) from Cura. I tested the stepper seperatly and its fine, it appeared that the stepper driver was not running. I ordered a replacement driver from digikey and soldered it on to come back to the same issue. Hooked up some jumpers from the test points on the board and saw that the E-STEP (T7) pin was not sending a pulse when sent a G1 E1. The board is running Marlin 1.1.9.
What could be the issue with the board?
TL:DR stepper driver is not getting drive signal on ANET-A10 board

It could simply be faulty mate.
I have purchased a backup board for this same reason
But in saying that, I have also done the mosfet upgrades for both heatbed (and heatbed upgrade) and extruder (and extruder upgrade to 50 w heater). So as yet, my board is still a happy little mother (board lol)…
Depending where you are for the sake of less than 1/4 of the price of the machine, look at a new board and go from there…
Are you heating your hot end before sending the E-stepper commands? I’m on stock firmware and there is a minimum hot-end temp for the E-stepper to work.
Heat it up and then try it again.
