Ultimaker 3 extended default steps/mm on x/y motor

[Yo-NuTZ 3]

I recently got an Ultimaker 3 second hand. Was pretty happy about it until I got home (was pretty cheap) and had the time to test it.

 

Prints aren't dimensionally accuratem they're off by 10mm and also it misses steps (layers from some point just slide to one side).

From my know how with previous printers it can be the pulleys, belt, motor or steps/mm.

 

In my config file they are 80mm/sec is this correct? If you are there mind telling me the default print steps for all motor and also the motor amperage since i've had some overheating & skipped steps? 

These are the values you are looking for: in my current version i could find them in: /usr/share/griffin/griffin/machines/um3.json

• default_steps_per_mm (all motors please)
• default_motor_current (same, all axes please)

 

Thanks in advance and also thank you to all members contributing, I've been lurking here and gathering know how
