I'm converting all 3 of my benchtop mill's axes to CNC. For the stepper drivers, I originally selected USDigital's MD1. Looking around, I've come across another that looks like a copy--Geckodrive's G201. The datasheets are almost identical, down to the resistor values for current control and the capacitor required for too-long power leads.
Geckodrive's price is $30 lower, but USDigital has a 2 year warranty and I've bought from them in the past.
Is one a ripoff? Or, are they the same device with different packaging? If they are, the $90 savings would sure come in handy elsewhere in the project...
