Welcome to the SeeMeCNC Community

Hi guys,

I'm in love with Rostock MAX. Great piece of engineering.
Building and initial calibration took me couple of days and finally I was able to print something useful - fan shroud. Of course I have also a bunch of calibration cubes. I'll post some pictures a bit later.

Best regards

Welcome to the Forum!
We would appreciate pictures, it's always good to see new pictures.
Happy Printing!

Ok, pictures. Bit of tape here and there.

First and second print:

First at 180, second at 195. Printing only in PLA so far.

Great job in getting it built. A little more calibration and you'll be printing with the best of them.
Happy Printing!

also, you should print that hotend fan with a material that can withstand the highest temps you will put it through.. I had minimal warping after many hours when i printed mine with abs

@bubbasnow Yeah, you're totally right. Do you think that nylon will be good for this?

Currently waiting for new thermistor. Fried the old one: isolation on heating resistor leads was burned to crisp and it touched hotend at some point. Now I know that ptfe sleeve or kapton tape is a must.

ABS is fine for the stock end fan. Don't try printing nylon with the stock end. You can melt your PEEK and PTFE - which emits toxic gas and leaves you dead in the water.

Thank you for warning, I've read somewhere that PEEK and PTFE should be ok up to 250, so I don't want to go above 240. Nylon won't print at 240?

Not all PEEK is the same. Most starts to degrade at 240. Nylon really needs to print at 255-260 to get optimal layer adhesion.

In general, I personally don't like pushing anything I own to its design limits, and I particularly avoid doing so when toxic gases are a potential outcome

I totally agree. I'm too old to die stupid death. Already ordered E3D hotend for printing with nylon.
