I bought a Robo 3d R1+ a month or two ago, I’ve been having problems with it since day one and I just don’t know how to fix it and even if I did I don’t have too much free time to be tinkering to fix it. I originally bought it for $350ish and had my hot end “break”, I bought a replacement for $60 and now it has new problems and I’ve spent most of my free time trying to fix it and I give up. I have the option to send it to a company to fix it but it would cost at least $150 but most likely $200. So now if I fix it that way it would be around $610 I’ve have spent on this $350 printer. And I just don’t know what to do. If I should repair it and spend the $600 or just bite the bullet and buy the CR-10. I wish I could sell my Robo to someone and use the money to get a new one but I highly doubt anyone would want to buy it in this shape. So please help me with any advice on what I should do.
Can you show pictures of it not extruding properly?
Not extruding for the first few seconds is normal; the plastic leaks out as it’s heated, so the extruder needs to “catch up” in a sense - this is what a skirt is for, it helps prime the nozzle before the actual print begins.
Depending on the buzzing sound, this could be a misaligned fan which happens quite frequently with cheap ones. Sometimes simply lightly stopping it and allowing it to spin up again can help.
