Have not been 3D Printing long enough to determine what would be ordinary.

I did receive kit including a factory flashed controller that the E-Stepper turned backwards.
Did not know how to fix without firmware changes other that reverse the cables.
Did not realize until purchasing the 2nd 3D Printer that the original cable was wired incorrectly.

I just helped a 3D Printer user fix his firmware from a direct download from Manufactures web site.
The first download was for his 3D Printer was a hex file, an the extruder E0 & E1 pin codes were swapped.
An his setup for the wrong Z- steps needed to change from 400 to 2560. We download the second firmware a Marlin source for his 3D Printer.
An the an extruder E0 & E1 pin codes were swapped. so he is now using the E0 zero thermister with the E1 extruder stepper motor.
I found the correction to change them to there correct state today and posted the fix.

Do not know if he will change though he has the fix and knows how to flash the fix...

Oh!!! I guess do know the answer

This would be a big O YES!!! this is ordinary for some manufactures of 3D Printers.
