Gecko g540 and 4.2A steppers. Can I add a resistor?

[terbospaghetti]

I'm new, and I apologize if I missed another thread that answers this question, but I'd like to ask how important the "current standby mode" is for my use case.

I'm converting an 8x16 lathe and I have two 4.2A rated steppers for the two axes and a gecko g540. I don't plan to run the machine every day, but I would like it to last as long as possible.

Should I solder a resistor into my db9 connectors to enable the "current standby mode" mentioned in the g540 manual?

If I can/should do that, do I use the same math as I would for a stepper rated less than 3.5A to determine resistor value?

Thanks in advance! And happy new year! Good riddance, 2020

Yes, put the resistor in for 3.5A, if you don't the drive will not go into stand by mode. This is explained in the manual:
