When you installed the new board,it may need to be reset. Go to the printer manager and see what machine and projector size it is set to. If it is correct, I would still reset it.
You can reset it by changing to a 1.2 machine , allow it to update, then set it back to the 1.1 machine and allow it to update.
In Printer settings ;where you set the steps,go to the top of the page, click on the question mark and bring the question mark to the steps setting box . It will now show you 3 settings for all 3 versions of the machine... 1.0, 1.1 and 1.2. Pick the correct one and it should work correctly
