Excellent for use on Molex, Tyco, JST, and many more terminals and connectorsDie width range from 1.6mm - 2.3mmSemi-soft elastomer grips provide a good comfortable feelFor use on most terminals and connectors in the #18 - #28 AWG rangeHigh quality precision crimping tool made in Japan
The Engineer PA-09 is one of the best "small pin" crimping tools for hobbyists. They aren't dirt cheap, but they are worth $40-$50 price, which is cheap compared to official tools from connector manufacturers. I own a PA-09 and highly recommend it. If you never crimp the smallest pins, then a PA-20 or PA-21 might be better for you.

Use a multimeter and check the voltage of your "fried" stepper driver. Connect + to the potentiometer and - to the psu GND or any other GND really. If it returns no voltage, then it is fried. If it returns a voltage, try the same on a stepper driver that you know works. If the voltages are roughly the same then they're tuned. If not, then adjust the one you thought you fried to the voltage of the stepper driver that works.
Personally, I've never been a fan of embedded stepper drivers, it isn't very future proof, not to mention many boards that come with embedded stepper drivers use cheap a4988 drivers. If you need to replace your board, the cheapest solution would be a ramps 1.4 + Arduino mega. An all in one solution would be something like the MKS GEN V1.X boards, like the v1.4. The advantage of the ramps over the MKS board is that if you feel you don't have enough computing power, or you want to add more features to your printer, you could always buy a Re-Arm and use it as a substitute for your arduino mega. You may need a crimper, and a set of DuPont connectors to make connectors fit though, whichever board you pick. I recommend the Engineer pa-09. As for stepper drivers, you can use A4988 drivers, but DRV8825 drivers are a bit better. One thing to note, is that shipping from china usually takes 3-6 weeks, if you need stepper drivers sooner than that, I have like 6 spares I could sell you.
another LPT: engineer crimpers are a thousand times better than the ratcheting style. But double the price, and yes you need two to cover every style of crimp out there.

I recomend getting one of these,should be available from amazon ger https://www.amazon.com/Engineer-PA-20-Universal-Terminal-Crimping/dp/B002AVVO7U
If that one is not available mdpcx has excellent crimper.You can also get sleeving from them
If you want to go full budget get paracord from ebay,heatshrink from local electronic shop or something along those lines.
I recomend getting atx terminals from ebay or ali just watch out that they MUST have long tabs(thing that go into cable).When i ordered some connectors i got extra pins which have sjort tabs and cant grip the cable good enough.
Connectors also from ebay/ali.Pm me if u want to know something morw
these (https://www.amazon.com/Engineer-PA-20-Universal-Terminal-Crimping/dp/B002AVVO7U) changed my view on the connectors. Those big stupid ratcheting ones are useless.
I don't have any experience with any other crimpers than the ones I mentioned above but these are pretty highly rated. You might also consider using heat shrink/solder butt connectors. I've got the kit I linked to here and have been impressed with it. You will need a heat gun though but no crimping involved. Just use enough heat to melt the solder and shrink the heat shrink .
