z-offset no longer moves the gantry up and down.
The machine worked fine for 2 months. Suddenly the z-offset stopped moving the gantry up and down. I tried updating the firmware, I even tried the community firmware on facebook.. Nothing has worked.. I emailed customer support over 4 weeks ago, Every 3-4 days they respond with an email with the same run around asking for my invoice number over and over even though I was a kickstarter backer #4162. #frustrated #sotiredofthiscrap #foolmeonce
