Hi all new here just come across this site and found some ctc threads

OK here goes

Had my black ctc printer for over 2 weeks now and since day one I've had problems with prints not coming out right size

I tried printing a side piece for me quadcopter and the screen sizes were correct so I printed it prints it 4mm to small in the length.

OK read online best to update to sailfish so after 2 days got it on printed still the same .

Print a 20mm cube

Comes out at 19.67x19.58.20.11mm

Emailed the seller no joy .

How do I get it to print to correct size .
