Talk:Tips for the TronXY P802MA and in general/@comment-86.153.248.50-20180226150535

I need to calibrate the x and y but am getting lost in how to change the firmware.

I printed an x/y calibration where they should both be 100mm, X = 98.22mm and Y = 105.55mm

what should i change via the lcd menu or does it have to be done via repetier host or arunio ide?

If i print anything as a large circle, it comes out oval.
