M906 reports E:0 on update to 1.19.2

I seem to be having the same issue with firmware version 2.01

It starts off with 0mA current; when I type in M906 E(any current over 1000ma), it starts to work fine.

Here is my excerpt from config.g:

M906 X2000 Y1500 Z1500 U1500 E1500:1500 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Thanks,
Madhu.

@madhunm, please post your whole config.g file.

@madhunm Try retyping the line from scratch in the config.

Done; no use.

After rebooting, M906 in the console results in:

M906
Motor current (mA) - X:2000, Y:1500, Z:1500, U:1500, E:0, idle factor 30%

What happens if you use E1500 in config.g instead of E1500:1500 ?

What happens if you enter that M906 command in the GCode Console, exactly as you have it in config.g?

When i use E1500, it works as expected; M906 reports:
Motor current (mA) - X:2000, Y:1500, Z:1500, U:1500, E:1500, idle factor 30%

When I type E1500:1500 in the gcode console, i get:
Error: GCodes: Attempt to read a GCode float array that is too long: M906 E1500:1500

Thanks,

M92 E146.27:146.27:146.27 ; Set steps/mm for extruders

I just noticed that your M92 for the E steppers steps per mm comes much later than for the other axis and after your other commands specify settings for a single E motor.

Try moving your e steps per mm M92 back up with your other axis.

That's as expected. Your config.g file contains this line:

M584 X0 Y1 Z2:3 U3 E4 P4

So you have only one extruder drive (E4 in the M584 command), not two.

Thanks a ton for your support!
