Hello!
In the specifications on our beloved printer, it says that the minimum layer height is 0.05mm.
But almost everytime i try to print that low, the nozzle cloggs and i have to stop the print.
Is 0.05 realy the lowest and no 0.1?
Regars, Fridh
Yes, it prints fine at 0,05mm
You need to calibrate the extruder though; it gives WAY too much filament. The steps used are 200 per/mm and it should be 151.94 per mm (in my case, at least) This is the reason why it clogs. You can also tweak these settings from within Slic3r, using the extruder multiplier, and fill in 0.75 there.
But a calibration would be the best. Just change these settings in the firmware (configuration.h) and upload them again. You can also adjust the steps per mm for the (e)xtruder using the devices UI.
Im running the pribter on 75% flow. Should that generate the same result as adjusting down the steps?
Also, the stuck filament occurs randomly over my prints. Everytime from 1-99% completion.
Yes, that leads to the same results.
I didn’t knew the nozzle clogged up, i thought you meant it was digging through the plastic.
About the jamming;
The nozzle can maintain its temperature?
What temps and what filament are you using?
What helps with PLA is using some oil to ‘season’ the hotend. (just apply it lightly on the filament) Use oil that doesn’t reach its smoke-point on the used temperature. Canola oil is perfectly suited, according to the experts.
the teflon tube inside the nozzle is absolutely perfect?
Hi,
I have just completed the Vertex K8400 build, removed the Extruder connector from the printhead and powered it on.
The next step is to check the LCD display but the screen is unreadable. I can see that there is something there but very dim, then I tried to adjust the potentiometer but with no luck.
Then I noticed that when i press the reset button, the text becomes very clear (readable), and that after the releasing reset button the display is readable for a second or so but then the text fades out (or dims). The backlight of the LCD remains the same.
How can I fix this?
Thanks for your help!

There are people that fixed this problem by removing and switching the driver boards of the steppers.
Cheers,

There could be a short somewhere.
Remove all the stepper drivers and check. If it still doesn’t work remove all the connectors (except the one to the LCD).
When you get a normal LCD display, put back in place all the things you removed one by one (don’t forget to unplug the printer between each).
So you’ll find where the problem lies.
