good morning!
I've recently bought a geeetech rostock 301 3D printer.
i though the toughest part would be the assembling process but, once i had the printer fully assembled, i realized that the hardest part was the configuration process. i've searched for information on different forums and everyone does it his own way so i am completely lost in the config process. in two months i haven't been able to print anything.
This printer i quite tricky, it is my third one. I must admit i'm not sure i would have been able to print anything if it has been my first one...
could someone give me some advices or a guide step by step about how to configure the printer once assembled.
which program do i should use? CURA, SLICER? REPETIER HOST, REPETIER SERVER?
1 You will use repetier host to control the printer, and inside repetier host, you will chose the slicer (cura or slic3r) you want. Slicer is the module that will translate the 3D model into a path, layer by layer, for the noozle
How do i put a correct configuration on REPETIER?
2 Configuring repetier is quite fast, and... just follow step buy step the geeetech 301 users guide. The only difficulty is to find the right com port. Ensure you choose 115000 bauds.
3 configuring slicer : Choose Cura as slicer engine into slicer tab of repetier, thn go into configuration (configuration button into slicer tab) Then just download and import into Cura my RCP (printer) and RCF (filament) settings (you can get them some posts ahead). They are correct for PLA. I prefer Cura, and geeetech describes how to configure Slic3r.
do i have to buy that blue tape the people use on those printers?
Yes : two advantages, it helps first layer to stick correctly to the bed, it protects a little the bed from nozzle crashes... Usefull for PLA. For ABS, people use borosillicate extra bed + Hair fixing spray. Just print PLA on blue tape, it is way simpler.
do the serial extruders will work properly or i have to buy the metal ones?
For some people stoc works (flintewn), not for me, neither for the guy whose name is extruder (see ahead). BTW, Metallic ones are cheap and easy to add. You'll see if you need them when you'll try your first prints.
Are the extruder fans necessary?
No. you can remove or unplug them.
are the scripts correct?
1- G0 X0 Y0 Z2
2- G0 X-73.61 Y-42.50 Z2
3 -G0 X0 Y85 Z2
4-G0 X73.61 Y-42.50 Z2
Script are used to level bed, to verify tha the noozzle is coorect for the Z, close to each tower and to center
for example Scrip 1 sends nozzle to the center of the bed at 2mm from bed. Scripts 2, 3 and 4 might send noozzle at 2mm from bed, close to each tower.
how do i correctly level the hot bed?
This is the tricky part.
Be patient. Once done correctly, you'll be able to print !!!
1 with a caliper ensure each of the 3 bed butterfly screw is exactly the same hight. If you don't own a caliper, use something solid tu verify the hight of each screw. (my momory is that bed is at arount 1.3 cm from the printer "floor" plate) What is important is that each scew gives the same distance for bed.
2 Your goal is that at the center of the bed (x,y = 0), at Z = 0,1, you can, with some difficulty, skid a A4 80 G shit of paper. At Z = 0 paper cannot move. At 0,2 shit moves quasy freely.
3 Your next goal is the same, but close to each tower. You can adjust your Z close to each tower with the screw + spring installed on the moving part, that hits the endstops switches on top of towers. Each time you adjust the screw, you must Home printer (G28) . Adjust the screws one by one. Adjust each tower one time and when finishd, do it again, because wht you move on one tower will have some influence on the others. Then try at the center of the ded.
4 When this is Ok with Z close to each tower (the paper trick), and if your noozle is far from bed at x and Y = 0, then your bed is concave (opposite is convex). See my previous post for how to correct this effect.
Using repetier ?
Choose a simple stl file (one in my previous posts)
Launch repetier host.
Connect printer.
load STL
Slice stl
Go to start printing.
You shold see head homing, then noozzle heating, the when at 210 ° (if you use my conf files) start printing...
Good luck !
