Re: Pla problems

I have been wondering if anyone had tried PLA yet. A few of the issues which have been documented on the plus is the PLA heating up and then getting stripped out so it fails to feed. Also it softening before going into the extruder and not pushing through properly. The stuttering noise you are heari...

Re: Calibration

It would be nice to know if this worked? As its treating the calibration print just like a normal print I would assume if the calibration was working it would change size.

Up Mini Bed Holder

I found that my mini bed holder was slightly too high which caused my print bed to bow up in the center.

I have created a replica with a variety of different heights so you can select the one which best fits in your UP mini.

Filament and Suppliers

Thought it would be good to have a list of suppliers and whether they have pp3dp filament and how well any other aftermarket filaments work. First one I would like to add to the list is Bibly CNC. I have used them often for my reprap supplies. I am currently testing their "High Temperature" filament...

Re: extruder not running smooth over X

Sounds like you have the extruder height set too low and it is running into the bed. I found that the center of mine was significantly higher than the edges.

Re: Warping, Part not sticking to raft

So I did a 7hr20min print lastnight with 0.2mm on fine with 4mm raft and it only lifted slighlty in one corner. I found that there was one patch which didn't stick very well and one section which I couldn't get off so it could still be something to do with my levelling. I wonder how the software pat...

Re: Warping, Part not sticking to raft

@marting: When you did the calibration of the bed level did you find that the center was slightly higher than the edges?

This was the case with mine and I am wondering whether this could be a factor in our prints lifting off the raft.

Re: [FEATURE REQUEST] Print Preheat Timer

Still I have found that preheating on my large parts, which have issues with warping helps. And this should be a relatively simple feature to add.

Re: [FEATURE REQUEST] Print Preheat Timer

There is also the 15min timer in the menu, but if you start a print it starts straight away. You should be able to set a time for it to wait then start printing.

[FEATURE REQUEST] Print Preheat Timer

For larger prints to ensure heating and reduce warping it is often suggested that you pre-heat the print bed. This also helps warm up the environment inside the chamber, which is particularly significant for the UP! mini. However as far as I know there is no option to pre-heat the printer. What I wo...

Re: Warping, Part not sticking to raft

I have done the calibration with mine and I am printing @ 0.2mm with the barrier closed.

I have been told printing on fast is better as it allows less time for the plastic to cool before coming around to do next layer. Do you agree? Or has anyone else had experience with this.

Re: Warping, Part not sticking to raft

Yeh I am getting exactly the same issues. I can't use 1.17 or lower as I need the bed levelling. If I don't then it pulls the raft up in the corners. Adding holes and changing the shape to break up long thin parts helps. I also found printing 4mm raft helps with the adhesion but not a great deal. St...

Re: Stop the beeping!!!!

This should be done in the firmware.. I realise having it settable is a fair bit of work but seriously firmware with beeping & a firmware without beeping should be easy. For those who print during the night. Just remove it. Can't be more than a 10min job. Or send me the firmware code..... Actually i...

Warping & Ways to avoid it.

So I have been trying to do some fairly big prints on my Mini and I was wondering what techniques people had up their sleeve to prevent failed parts as much as possible. One of the parts which I have had issues with is a 120mm x 3mm x 60mm plate which I had to print on its side diagonally as that wa...

Nope you can't go down. Designed to force people to upgrade. I can export to IGES if that is better. Usually works better than importing stl.
