I will invite you to do some calculation about the linear expansion of a filament of PLA ... http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html Linear expansion is pure thermal expansion -- that is what happens to the filament when it gets hotter, and I agree it is not signif...

Hi Neotko! Still don't understand your explanation... Seem that you talk about "heat" (caused by IR irradiation) like if it was a fluid... really this doesn't make sense for me ... The problem is the following: when you retract you bring hot filament higher in the head. If you just retrac...

It seems like Arduino is kind of falling apart - high time to move away from them and find something reliable if you ask me. Yes, it's true that the Arduino situation is not so good. And time will tell if the .cc crew can get it's act together for the long run. The split in the team is now 18 month...

Hi, What is the material name or properties? Do you have any contact number from them ? It's called PLA XRS -- I don't know much more about it... There is an e-mail on their contact page, they are on twitter as @nanovia_tech. Alternatively you can contact Riggs on the forum he has good contact with...

I just updated to conform with latest API, it should work now.

Utrecht is not very far, but I am just just back from the US, so not keen to drive today...

I said inductive because I have a couple in my toolbox and they give very good results on my CNC... I can power the switch directly from the PSU, but need to reduce the signal voltage (opto or divider, ...)

I haven't look at the code, but I am very skeptical that these switches achieve that level of accuracy (in particular when they are mounted like you did)...
I think if I go that way, I'll use an inductive switch.

0.2mm error is not that bad for 3D printing given the mechanical parts on one side and the material on the other (plastic shrinking)... From your table it seems that the error is more or less constant regardless of the size of the model, so I would exclude bad settings (like step/mm). I would look a...

The only part i can think of that might be impossible to get is the step-down board that is included in the heated bed upgrade kit to step down the 24V power supply to 19V... but you can pick up a step-downmodule for cheap on eBay to do more or less the same thing. ... And the PT100 converter (whic...

Indeed, I double checked on Github, there is no recent change for the UMO(+) firmware. The firmware announcement with the new Cura is only for the UM2 line (and the max temp stuff is already covered in my fork)
