Thank you for your post.
Could you send me the ticket ID number that you have send (in a PM if you prefer)?
I will get it sorted out and get you 2 new stepperdrivers if this is indeed necessary.
Could you perhaps post a picture of how it got delivered to you?
It would rule out any miscommunication of any kind
Looking forward hearing from you and sort this out. And get you back to 3D printing asap.
That's an understatement. Did you use support.ultimaker.com? Anyway I bet we can get this running within a day or two if you are in a rush without them. Also posting here might get their attention.
I am very familiar with the PCB (I see it in my sleep) but I want to make sure I understand. The stepper drivers are often referred to as "pololu" drivers. They are little modules that can plug in and unplug from the board. Do you mean to say someone inserted 2 of them backwards? If true this will indeed destroy them.
You can get just as good (or better) pololu drivers and they aren't expensive. I recommend you order 2 (and then maybe you will get 2 more from Ultimaker as spares later on). It appears you are in USA? Is that correct? Can you please update your profile and enter your country (location) please?
Daid (is a programmer - not hardware guy - at Ultimaker) recommends pololu black:
