Hey There,
I am guessing right now on schematics and things. So, I will be working more on the schematic on Kicad and this specific schematic incorporates Pololu stepper drivers.
What set of stepper drivers that you all carry can handle the most current per phase?
I mean…I read the details on the main page but came up with 4.5A maximum/Peak of current on the Toshiba type. Is this one, the 3097, having the highest Peak current available for your stepper drivers?
Update
Also, do all of your stepper drivers have the same pinout? I mean to ask if GND is GND on all stepper drivers at the same location on the driver board?
Hello.
I moved your post to a more appropriate section of the forum.
For reference, you can find tables comparing the specifications of all of our stepper motor drivers (including the maximum continuous current per phase and peak current per phase) on our Stepper Motor Drivers category page. Please note that the maximum continuous current per phase was determined from our testing in an open, room temperature environment, without any additional cooling; if you want to operate beyond those values, you will likely need to add some cooling of some sort. Additionally, as noted on that page, the first two tables show our compact stepper motor drivers, which come in pin-compatible form factors.
Our most powerful driver is the High-Power Stepper Motor Driver 36v8, which can handle 8A continuously per phase (up to 11A maximum with additional cooling). However, please note that unlike most of our other drivers, the High-Power Stepper Motor Driver requires configuration through its SPI interface on each power up (even if you want to use the STEP/DIR interface).
If you do not want to use an SPI interface, the next most powerful would be the TB67S128FTG Stepper Motor Driver Carrier, which can handle approximately 2.1A continuously (up to 5A peak).
Alternatively, you could consider the Tic 36v4 Stepper Motor Controller, which can handle 4A continuously (up to 6A peak) and can be configured via USB to use several different interfaces (including STEP/DIR, USB, TTL serial, I²C, analog voltage, quadrature encoder, and hobby radio control). Unlike the High-Power Stepper Motor Driver 36v8, the configuration settings persist through power cycles, so the Tic only needs to be configured once.

This is a machine for STEP/DIR and needs the pin-compatible form factor of 8 * 8.
I was going to make a daughter card PCB and the spacing is intended for the Pololu Stepper Motor Drivers.
I will look to the Pololu - TB67S128FTG Stepper Motor Driver Carrier as a second option. I appreciate your time.
