    The main problem, I have found, is bed adhesion. It is a bit of a titser when a corner lifts. I have tried different bed temperatures and bed substrates (Kapton tape, masking tape, ABS washes etc) The current one giving me some success is frosted glass with an ABS wash (thin solution of ABS in Methyl Ethyl Ketone or Acetone (Dimethyl ketone). I now run the bed at 110 degC for ABS and I don't print with anything else.

    I bought the steel framed model for rigidity and I feel it was a wise decision. The second extruder has hardly been used, I have never seen much necessity for two colour prints.

    I am about to rebuild the RH extruder as there is wear on the feed gear and the plastic frame has a pear shaped hole where the filament feeds, which makes it awkward to change filament.

    I always print from SD cards as I can turn everything else off in my den and go to bed, leaving the machine chugging away (all night sometimes).

    One last point :- Sam Courtenay, the Agent for Wanhao in UK is one of the most helpful people I know in 3D printing, sending me related parts, in case they were needed, when I only ordered and paid for the primary bit I needed.

    Cheers,

    i have a wanhao duplicator as well been in constant use for months now, no problems other than sometimes the pc loses connection but printing from the memory card is a doddle anyway, It is the steel framed one and it came pre assembled just had to bolt the gantry on. Was printing within 30 mins of opening the box and is a very accurate machine, never had any problems with bed adhesion on the stock bed. Wanhoa have good support and there are plenty of user groups around as well. Takes a little while to learn the nuances of the software but had some great results.
    I think the machine was 280 and delivered within a few days. Bought it of amazon.
