Hey guys new to the 3d printing stuff but had some very good results out the box with my ctc.

unfortunately after my last print everything has gone wrong and cant get it back again.

I have changed the filament from what come with the ctc to rigid ink stuff and leveled the bed countless times. also checked the nozzle for a block.

some parts of the bed i get a good print then in the center or towards the back seems like nothing is coming out the nozzle and drags parts of the print off the bed.

could it be the bed is warped already? has anyone had issues with the alu bed?

thanks
