Yes. Load your first model into MatterControl, then go into Edit mode. You can then drag and drop additional STLs into the edit view, and they will be added to the same print. You can also hit copy to print more than one of the same object.
It seems like you've got things backwards. PLA is supposed to be stored in a dry environment. Moisture is what causes it to have issues. This effect is called hygroscopy, and there's more information about it in this thread.
In any case it sounds like you just had a bad spot in the spool. If you find that the rest of the spools is excessively brittle, contact email@example.com and we will replace it.
i find with certain poor quality filament the moisture content is very high, this will steam and pop a lot, but if you do want to use it,i find if i slow down the print speed to 20% and heat up to 240 and walk away... tbh rather get some pla.
Awesome! We look forward to you getting thing going as well. Reach out if you have any questions - there are many Rostock MAX builders within the community. Happy Printing, well... building for the first part of your career.
Moved this into it's own thread. Please do not hijack other people's threads in the future.
The MAKEiT meets most of your requirements, although the manufacturer specifies the maximum hot end temperature to be 275 C, not 300, and the bed size is slightly smaller than you want.
My question for you is, do you really need a second extruder? Most people who are getting started think they will need dual extrusion for support material, but in most cases it is unecessary and more trouble than its worth.
Yea messaged the creator and he made the lines thicker so I only had to scale up the model by 10% which is no biggie. I got it to slice correctly after he made the lines thicker but I still have another problem when printing the outer ring gets dislodged while printing and messing up the whole print so I was thinking of adding some support to the outer ring to connect to his manual support so it wont dislodge. I have my fan on max but the plastic still curls like crazy so I will try adding some support so the outer ring doenst come off while printing.
This is the toughest thing i've tried to print and I have printing a lot of stuff this is the first thing giving me trouble.
There isn't really a "extrusion speed" setting, but extrusion rate can be adjusted by using the Extrusion Multiplier function. This is a slice setting, but can also be adjusted on the fly during printing.
