Hello all, I decided to do what I should have done from the start: ask the community! I backed the original kickstarter offering of the R1, and I was more than happy to back the second campaign. I pledged for the c2. It arrived last month and I was thrilled...with the ONE PRINT i have made with it. I've been trying to print and no matter how i sent the file (octoprint, usb, etc.) things start to print and then I get a "mainboard not connected" error. I've sliced in both cura and simplify 3d. same results every time. Tech support has been no help. I actually received this as a reply: Judging from first email, It looks like he has a “Error: MINTEMP triggered, system stopped!”. This can mean either of 3 things: 1) the thermistor is unplugged or malfunctioning 2) the extruder is unplugged or malfunctioning 3) the mainboard is malfunctioning. that's it! no instruction or offer to correct the situation. It's like a firetruck showing up to your house fire and saying, "yeah...she's a burning alright!" Has anyone experienced any issues with the mainboard not connected issues or the above error code? I've updated all my frimware, physically checked all connections, and i'm still at a loss. Thanks in advance for any input or ideas you may have.
