Is the CR-X Pro right for my requirements

  • I'm in the market to buy a 3D printer, price range around that which the CR-X Pro sells for. I've printed a lot before, but always with other folks printers. So I've a huge amount of printing experience, a small amount of printer maintainence experience (mostly unpleasant), and no experience picking printers to use.

    The main sort I've used before was a Robox Dual but that is a) a bit above my prive range, b) not great value I think and c)very hard to repair and maintain, plus d) out of stock everywhere right now.

    I'm after something, preferably dual material so I can use a weak material, of different colour to my main plastic, as support strut. I really like having a weak material as supprot strut which is very easy to breakaway with pliers, or so weak infact a lot it comes off by hand. I am not interested in dual colour printing for arts sake, but printing with a normal material plus a weak support strut is extremely useful to me. A support strut substance like this kind:

    For dual colour printing if some of the two filaments get mixed you get an ugly colour smear at interfaces, but for printing with a proper plastic and a support strut plastic if they get mixed that can really hurt part quality, and it might be dificult for a single nozzle to handle switching over between two dissimilar materials too? Does the CR-X Pro handle this well and cope with two dissimlar filament materials given that they would both be extruded via the same nozzle and therefore a potential risk of one with a different melting point gumming up the other at the moment of swapping between materials?

    I'm after something quite maintainable, something where if parts fail I can buy new ones from a wide variety of sources, I don't need full open source but something close to it would be nice. Absolutely must take filament of standard size and from any brand, and cheap filament too.

    I absolutely require something that can be operated entirely with open source slicer and control software, and must not require any proprietary, or windows only, software for setup calibration or anything else.

    I have an absolute requirement I must be able to do everything from only a linux PC. I'm after something compatible with a wide range of slicers.

    I print a lot of gears and a lot of things with substantial overhang, hence the dual filament desirability. I'd also appreciate something which prints fairly mechanically strong parts, where the subsequent layers will melt in to each other a bit, and where I can do solid or many-perimetered parts without much warping, either in PLA (preferable) or ABS, although nylon filament looks tempting if easy to use, I hear it can be self-lubricating and very good for gears.

    I'm after a build volume around 20x25cm x-y and 15cm, or a little less, on the z height.

    The printer must not require any interent connection or wifi at any point during setup or operation, also must not require any windows only software, I use linux only.

    I would always be printing with a layer height of 0.2mm.

    Automated and safety features that let me concentrate more on designing parts and less on worrying if they'll print are welcomed, I think heated bed is crucial and I don't know about auto-levelling, a semi-enclosed build chamber could be useful if reducing airflow and getting warm can help give stronger prints, but must be one which can be opened mid-print and where the head can be paused in realtime. (that way if an ugly glob of plastic builds up on the nozzle during printing I can pause it and tweezer it off without having to loose the print).

    Is the CR-X Pro right for me?
    Thank you
