They offered to replace the print head, but I told them this printer blows chunks and I want it replaced with a different model, the Adventurer 4 Pro.
There are problems besides the print head getting clogged so I don't think replacing it will be sufficient.
I have made 3 more attempts to print objects, and not once has the printer completed an object before it detaches itself from the plate after about 20 minutes of printing. Attached is a pic of 3 partially completed print jobs. This printer is a piece of junk.
I would like to replace this printer with a different model, the Adventurer 4 Pro. I will return the A5M in the packaging the A4P comes in. If the A4P actually works, I will pay the difference in price, which is about $150 I have seen advertized.
I am attaching also the invoice from Amazon.
The A4P has been around longer so hopefully is better tested. It also has a glass enclosed print bed, and my CAD program works with it directly so I shouldn't have to shuttle between programs importing and exporting .stl files..
We'll see if they go for the exchange.
