Ok so my bed is flat printing with a ffpro and abs, when I create an object like a spool sleeve its dimensions are 52mm outside and 30 mm inside.im using sketch up. on 3d mm setting. When I use simply and print out model it comes out .5 mm to small. but ive printed a calibration cube using a penny and its exact.i tried a few prints some times its up to 1 mm off. im using stock settings in advanced 10 on infill to make it quicker to print. any ideas where to start to fix this issue?

I would suggest this. Go to help --> reset all settings. Then after you restart the software you will see the config assistant. Choose the FlashForge Creator Pro. Then don't change any other settings and try a test print.

My guess is that your firmware config and steps/mm settings were wrong. Thankfully, the config assistant will fix all of that for you.
