After powering this on and connecting to it I can’t get the stepper motors to move.
Do I have the drivers installed on the card correctly?
What steps can I take to troubleshoot?
You have given us virtually no information about what you have along with a misleading photograph.
Might want to give us a little more background about what you are doing… It appears these have never worked?
Is this a diy project?
Which motors are you using?
Does this have home/limit switches on it?
Where did you get the $100, $101 and $102 values?
They are supposedly created this way…
Steps/mm = (Steps per Revolution)(Microsteps) / (mm per Revolution)*
I know mine are not whole round numbers…
I can’t find anything about how the driver boards plug in…
None of the ones I’ve seen had a heat sink on them… you will have to search around to ensure they are plugged in properly… If they are not, you might want to order a new pair… They usually don’t tolerate being put in backwards…

Relax, pal. Sorry about the “misleading” photo.
I got the values from this page.
The machine is a Sculpfun S9. I have limit switches but have not connected them to the board yet.
The stepper motor drivers came with those heatsinks so I assumed that it was probably best to use them. I think that I have them installed correctly. https://diode-laser-wiki.com/wp-content/uploads/2022/08/IMG_3120_small.jpg
Great, what you should have done, was keep the configuration (the $ value variable) from the original controller… Always save configuration information as it may not be the same as what the default values are.
Don’t have one of these machines, but I assume it’s grbl and you can use the same mechanism to change the new configuration.
If you didn’t save your original controller data…
Try connecting the original board and see if Lightburn will talk to it. If so, you can just use Machine Settings to read and save them… change to the new board and load then write the original settings to the new board…
I have a couple of them around and just the usb power is enough for them to talk, no need for a larger supply.
That would give you reasonable values… and we can go from there…
My MKS DLC have a touch scren display but is similar to yours.
I had some problems configuring it at the beginning but i solve them all adjusting parameters through lightburn.
I started with Lasergrbl too, I had mostly issues with inverted movements of the axis.
I don´t have the machine connected in this seat so I can´t help you with configuration.
The firmware values you chose look ok. Anyhow, if some of them were wrong, it shouldn’t affect the motor’s physical movement. The movement can be wrong (wrong direction or wrong dimension), but they would still move. So, I suspect an electrical issue. Mounting the stepper drivers correctly is a crucial thing. Don’t judge from pictures because different drivers may have a different layout. The easiest is as follows: find the enable pin of the driver. It is in one of the corners. It is usually labeled as EN. This pin has to go bottom-left (so the first pin of the green row). Make sure it’s plugged in like that. Otherwise, they might already be broken.
Did you change anything at the cabling? That should stay as usual. How did you send movement commands? Using the arrow-buttons? What feedback did you get in the console window?
