How to test ONLY Stepper Motor on DIY ULTIMAKER 2 Printer

[KASHMIR 0]

Hi

I need some help.

I have an Ultimaker 2 controller board, and i want to test if the stepper motors work

by using pronterface. I built my own 3D printer similar to Ultimaker.

I tried plugging the Y motor only on the board, nothing else is plugged in.

Just want to test it in pronterface if motors work.

But when i use pronterface, i keep on getting MAX Temp Error,

click Y axis , nothing moves.

Is there some modifications that need to done to trick the board into thinking

that there are no temp sensors or heatbed ??

I would appreciate if someone can help me out.

Thanks

You say that you've built a printer that is similar to the Ultimaker, do you happen to have a temp sensor? Why not just plug that in? Or you could try tricking the firmware by plugging in a resistor in that connector, 108ohms is "room temp", so any resistor close to that should work.

I'm told you can just short the temperature pins together - not sure why that works (would think some kind of temp error) but I saw it working for someone a few days ago.
