What is the Deal with Pul+,Dir+,Pul- and Dir-. Should i use only negative, only positive

[Benedikt Zeilinger]

Hi everyone,

i haven't been able to get my head arround this. The most people I've seen, use the negative Dir and Pul. Positive are connected to the 5V of the Arduino.

However i have also seen some people using the positive Pins for control, and just putting the negatives to the ground (which seems somehow easier).

What is the deal, and do i have to change settings in AccelStepper to do so? Or can i use all of them? Does that bring any advantages?

Im using this setup with NEMA 17 and TB6600 (https://www.amazon.de/gp/product/B06XT3HKRX?pf_rd_p=f7bdfbd1-e064-4693-a582-bc6376fbd365&pf_rd_r=F2Z8QJADQNWTR3B0217V)

Best regards

Hello. the TB 6600 works connecting all the positives sending them to + 5v, while the negatives Pulse-, dir- and enable - to the pins of arduino example 4,5,6. TB 6600 does not work by connecting negatives.
