Bought the Ender 3 v2 printer.It didn't work from day 1. After numerous calls with technical support the problem wasn't solved. After trying various tasks that was suggested by Creality, which took several days, I requested a refund. Technical support texted that I would be contacted within 48 hours by sales. Waited for 48 hours with no contact. Since then, I have emailed customer support and sales many times with no response. My mistake was that I purchased the printer from Creality's web site and not a retailer that supports what they sell.
