    The $500 - CTC Bizer series Dual Nozzle 3D Printer

    Picked up one of these last week on ebay from CTCprinter2014.

    Fast shipping, all looked well until I saw a USB dongle.

    The Dongle says filament usb+

    There is a nice yellow sticker that both the seller and the CTC site do not show or mention is the description. It is a proprietary count down timer that runs off the usb. ( Do not plug it into the computer as it will fry it )

    so basically you are screwed into waiting for them to ship you overpriced filament after every 150 hours of print time.
    What a scam...
    I thought id share my frustration and warn any new potential buyers that they are about to be scammed by the beginning of the DRM / HASP


    but there is hope... for only $10 every 1 hour you can print with extra usb keys! that you can then again wait another week+ for delivery for.

    Product specification:
    Printing time:1 hour
    Weight: about 0.1 kg

    Package Size:19 x19x8.5cm
    Filament diameter variation:less than +/-0.1mm
    Print temprature range 170 - 230 celsius(PLA)

    I thought id also mention I have emailed the CTC website about this issue and false advertisement / entrapment. Of-course no response... The ebay seller responded and could only offer a discount on the 1 hour usb keys. 4 hours for 35$. It was a nice gesture but im not paying anything more for a lie.

    I see CTC is on this forum so hope they can chime in on a workaround or an explanation for the bait and switch.

    Today im working on a way to disable or bypass this, if I find one I will update the topic.

    Update: seller is willing to send me the old board that doesnt have the USB+ anyone know if there is any incompatibility with new layout vs old models? for example lets say the older model without USB+ didnt have a heated bed. so would i loose the heated bed? any help would be supportive.

    sneaky bastards.

    So how does a usb stick stop you using different filament ?

    OR does it disable the printer after 150 hours.

    Either one doesn't sound like ctc. They're usually pretty decent.

    Very odd.

    This may be a daft question - but have you actually tried to load some filament without the dongle inserted ?

    It doesnt. Just counts down from "150 hours" when you run out, you cannot operate the printer anylonger other than to home, and level.

    Yes

    Yes, I have used 4 colors now, and they all work great. Today I got a replacement ATmega1280 Board no issues without sending out the old first ( make sure it works ) and ill return the USB+ one tomorrow. New "old style" board is printing well. No issues. So I would suggest asking and VERIFYING that the one you intend on purchasing is indeed NOT USB+

    Seller ctc3dprinter2014 Was A+ In Resolving the issue. Went from furious to happy. Back to making mods!

    Well I would not buy one if I knew it had the usb+ socket fitted, don't ctc realise people want to make their own choice of filament brand they should learn off the inkjet printer suppliers or people will just come up with a workaround for it.

    some constructive criticism that was a bad move to implement the USB+ restriction
    i was literally gonna order a ctc printer as my first printer until i came on here and read about the USB+ fiasco and ended up ordering something else
    the only thing that came to mind was...wow what a greedy company for doing that
    but at least there is some hope for people who got scammed i might buy one if i can find one without the USB+ as it does seem like the printers are solid
