@scerbera Design possibilities narrow when you go above 135C and even more at 150C where Misumi high temperature rails are rated. I have a feeling that gates 135C belts can do 150C at the low loads we use for 3D printing so as soon as my build is finished I will try it out. If you go above 150C you need to protect the rails from the heat. The Railcore community have tried the IGUS bearings, they do work but quality is not quite as high as with rails because of higher friction.

I would get the new Duet3 at the moment. Another option is the Duet2 wifi with a Duex5 but they are in short supply at the moment because of COVID19 shortages of one of the chips used for those older boards.

You need very different chamber temperatures to print PEEK and ULTEM. PEEK can be printed in low quality at 90C and high quality at 125C ULTEM needs at least 150C for the low temp version and 200C for the high temp version. I can also recommend to print PEKK instead of PEEK as it is easier to print and have better interlayer adhesion as well as superior temperature and strength stats. The Railcore II 300ZL can be modified resonably easily into a 135C chamber printer. It only needs a top enclosure and a door to be fully enclosed and you can use 135C rated gates belts as well as aluminum structural parts inside the printer. 180C winding pancake steppers for the extruder are also redily available and AB and Z steppers are outside the chamber. A modified Railcore II 300ZL would cost you arround 3500 Euros with stainless steel panels and all aluminum structural parts, heater, magbed, tramming system and everything else needed to make it a high temperature printer.

@jballard86 Yes, thats the one I sell at my EU based shop: https://hightemp3d.com/collections/mandala-rose-work/products/kinematic-mounting-kit-from-mandala-rose-works

@giostark Hi Sergio
Happy to have you as a customer. The Railcore kit is extremely stable. Only very few 3D printed parts are used so it is long term stable and extremely stiff. At the moment the only 3D printed parts are the feet, electronics enclosure corners, Endstops and BLtouch mount. The BLTouch mount will also soon be aluminum. In the near future there will also be a 135C chamber temperature version of the kit.
