i took the glas off the bed.cause the back screws off the bed is slitly grazing the block where the rods are for the bed. also i see alot of sparkelings from the rods on the belt.i think the machien is worn out. i will test the cube in about 6 houres.i can make a video.

here is a video with some grinding sound.

back into printing.i can fix the printer for a few dollars.so i am going to fix the printer. i can learn alot from this repairment.here's what i found yesterday. some times i hear a chort crack sound.this seems to be a happen alot. printing the cube.later i post some pics.here a pic off part of the problem.

here's the start from the cube .

now i have a leak to fix.but i am able to print.

some interesting details about leveling the bed. first thing i saw is a faulty speed for the first layer .you need to set the speed half for the first layer. second is the way you level the bed ,see picture.numbers are the screws on the bed, except for number 5 .

here's a part printed half speed.its awesome.

i finally maneged to get the bed leveling right. here's a paper that comes when bying a printer. its a little thicker then a A4 paper.

what i learn is this.slight this under the nozzel when bed temp is atleast 30 heat or the temp that you use. loosen the screw untill the paper gets stuck under the nozzel.then gently tighten the screws and at same time pull the paper from underneed, the nozzel.here you will find two things .eather the paper chift in small amount from underneed the nozzel, or all the way.these two are your messurment,your setting chould be between these two . when printing a raft it chould look like this. see pic.no curls,no thin lines.no pullin back filament.

you can also see the color is very clear.no warping or lifting from the print. i use the UHU stick ones.on a clean bed.110 heat extruder.30 heat bed. half speed.
