Keep track of every setting. Whenever you save a gcode file the settings that you used get saved along with it at the end. You can later choose "file" "load profile from gcode" to see what settings you used at the time. Write down the most important settings: speed, temperature, layer height.
I recommend you stick with .2mm layers for 99% of what you print. But vary speed and temperature often depending on your needs.
Everytime you start a print have a notebook where the student must write down the date/time which gcode file was printed, color of filament, and a few details like the 3 parameters I mentioned above.

I don't know if there is something that explains them. And they change when you start printing (tune menu).
Don't mess with jerk. lol. It's fine as it is.
In physics velocity is the change in position (derivative). Accel is change in velocity. Jerk is change in acceleration. But Everything is discreet in the software (not continuous) so jerk is always infinite at the vertex of every move (theoretically).
So instead they created something called "jerk" but it's not jerk. It's a max delta velocity vector at the vertex.
So if X velocity is 100mm/sec and y velocity is 0 and you hit a 90 degree corner at that speed, jerk would be considered to be sqrt(100^2+100^2) or 70.7mm/sec. Since max jerk is set to something like 10 or 20 mm/sec the X axis is instead slowed down to the speed =(max jerk*1.404). This is for 90 degree corners. for only slight angle change the UM doesn't slow down as much because the velocity change at the vertex is smaller.
Your very clear example makes me wonder... If an axis slows down like you calculated, will this effect the filamentfeader? When the axis slows down to 70 and filament is still pushed for 100, wouldn't that give a bit more filament at those slowdown positions?? Or will the filamentfeader/extruder automatically adjust??

I notice the "ViewMode"-button is gone.. Also the "PreparePrint"-button is gone and the "Print"-button has a progressbar beneath it... The "Preparing Print"-bar at the bottom of the Cura-screen is not there.. Can't tell if slicing or printing is in progress, but the two green blocks look like they're floating.. Could they be a visible layer-indicator of a used plugin like "Pause at height" ? For me the green blocks can be anything, even a manual positionable, adjustable supportstructure if 'Exterieur support only' is just to much and 'None' to less...

Ahhhh... A new timerbelt... :-P
And a brandnew Steam Engine Beta.. That's great Daid, keep up the good work How much water will be needed to keep it pressurized?? :shock:

Hi Gijs,
I've ordered a roll of the Signal Yellow and it's just perfect.. It seems to me that it prints even a bit smoother than just PLA, the pricing is very ok and the thickness is very constant (2,85mm).. I think we have a top-quality-product here..

My hot is broken. It was leaking filament on top of the aluminium block. In preventing filament melting over the temp and heater elements I removed the hot end. Trying to fasten the piece on top of the alu-block, it broke off...
Just did 1 print on a brand new machine and already in need of a new hot end... :oops:

Why should i buy an ulticontroller??? swapping SDcards all the time is not my thing.. While i'm printing through USB on my UM1 Original, i surely can do a lot more work.. Creating, converting to STL and in Cura to GCode and then instantly printing works a lot faster then putting my work to SDcards... Why not putting the ulticontroller-menu into Cura so all functionality can be used by USB too??? My computer is a multitasking- machine which allows me to use cura, solidworks, internet and a lot of other programs simultaniously... never had a problem with that. The only advantage, as i see it, is that with an ulticontroller you can do prints without turning a computer on, but mine is always on...
