Got competition already?

You can try but one of the design he sent is not an easy print.

Hehe, High quality pro prints are your territory.

Not easy? Lots of overhangs?

More like floating platforms.

Eh. You go ahead then Cant assure quality like that

hi guys, having issue after changing the hotend, now my kossel mini is running without auto probe due to hotend size. the 10mm printed cube having one of the vertical face convex and the opposite face concave ... anyone have such experience?

Is the cube a little shorter than before? I have not experience this issue before but to me it looks like your cube is a printed at a much higher temperature than before. It could also be caused by several factors like ambient heat from the hotend, the z-axis step calibration is out, or the x and y axis are wobbling.

What would happen if you print a thin wall or a thin wall cross.

yea...seems temperature is the issue, was printing at 215, dropped to 205 and got a perfect 20mm cube...thx

Glad to know it was resolved easily. You should try printing at a lower temperature, say around 195, so you reduce your chances of clogging up your nozzle in the long run. If you know how to configure your slicer to print at different temperatures at certain time/layer height, then my recommendation is to print at high temp around 215 and bring it down slowly to 195 after the first layer. This way you get both good bed adhesion and non-melted looking prints.

Thanks for the tips...will try that

guys...another issue need advise...the print was ok until it shifted everything to the right then after awhile it shifted back to original...kinda weird...slicer problem ?

also i notice my kossel mini got lifted slightly of the ground, cant pin point which side got lifted up cos it happen randomly

Seems like a hardware issue, did your stepper motor skip a step or got stuck in that particular axis during the print?

I don't understand the part you said "lifting slightly of the ground"

Lifted slightly...kossel mini has a triangle base, imagine what it will sound like when u lift one of the corner or edge and drop it...i heard that randomly but not often

Im also suspecting one of the stepper motor having sudden surge of power and turn too hard that cause the lift and drop sound.

Btw, thanks for the printing again...your ultra layer height just superb...can use auto probe again.

anyone have extra heatbed thermistor for sale? RS is selling pack of 5 and i only need 1

I think this could be due to the hotend crashing into the print which causes the sound. I had a issue with a reprap 3d printer that kept crashing into the print and the whole layers just offsets in one axis. The crashing is caused by the flimsy frame of the printer when the printer shakes, there is a chance the frame flexes and the hotend hits a part of the print causing the crashing sound. I don't know how if this fact can be applied to your delta printer but you could try running the print at a slower speed or checking the frame for any loose joints.

Glad the print turn out ok for you. I would appreciate if you could post a comment or feedback in my lowyat sales page in my signature. Extra points for post with picture.

Do you mean you need an extra 100k NTC thermistor?

Yes.need 1 for the heatbed.

Welcome back, blomker! It is awesome.

What you guys think about those china make cheap 3d printer ? The price range is about RM1200-RM2000.

Can it print ?

dont expect them to be ready-to-use out of the box. They'll require tinkering to get them printing at acceptable level. But the prices are okay. If you are really into 3D printing expect to add a few more hundreds in upgrading components of the printer like a better hotend or a new drive etc.

BTW, looking for a new hotend, can anyone PM if they have one for sale? Thanks.

Thanks for your advise.

I m more consent about the board and the driver electronic side. Is the board and the driver capable of upgrade to fine printing? Or it is capable fine printing. But limited to mechanism quality?

For the mechanism side, I m not so worry. I can upgrade it to the expert level.
