Today my printer was ready for the first print. I started the benchy printing with petg but it prints just separated thin strings on the bed. I tried a new vacuum sealed role but same result. I tried it with new role of pla but same result.
Can anyone help with this issue?
Funny, to the end i heard that sound and the steppers jump a little bit, so the benchy looks a bit strange now. My be is the travel speed to high?
great, thank you. Juicy description!
An other question, after short time of usage i can see some abrasion from the belts. Have I tightened the belts
too much?
Danke, danke!
Sorry, i have to say something in German:
DANKE MÄNNERS!
It looks good, the stepper current was the solution!
Hello guys,
i've the same problem.
I build my P3 yesterday. It have a direct extruder and a harden nozzle(0.4). Everything is new and i followed the manuals. I added the P3 to my current Cura and try a benchy with the standard pla configuration:
it was a nightmare of unterextrusion and clogging
I checked the e stepps, and with 220° and slow speed, it extrudes perfect 100mm.
So i try 215° and 65° and line width 0.4 (standard 0.44).
Still big problems, the Germans say underextrusion his father and the retract configuration seems to be wrong.
Ok I know that stell nozzle is more for abrasive filaments. But thought maybe the brass nozzle have a bad quality. But if your nozzles are OK and print well I'll use brass...
If your objects aren’t sticking, you should firstly level your bed manually:
- disable motors
- place 4 cans of redbull or another of your favorite canned beverages under the profiles and turn the Z lead screws down so that all ends are slightly touching the cans. - take away the cans
- level your bed
- check if your Z-offset is right
- print
for those extruding issues, I wrote in another post from Akisame, that he should take of his filament, clean the Hotend, heat up everything to temperature and then screw a new nozzle in.
Pretty sure that‘ll solve your issue too.
I printed the first layer (225°) with 130% flow and there are still gaps (with 100% just thin strings). All other layers are printed with 220° and 95%, at a height of about 15mm the nozzle begins to scratching on the print-object. But the layers do not stick on each other (not well in z and really bad in x/y).
The ready cube fits nearly in x/y (less then 0.1mm under 20mm) but z is with 20,35mm too high...
My bed is leveled, ubl was successful but the nozzle is scratching in the right front corner area.
I have no idea which values I should change without making one of the other worse...
Nice! Consider changing the flow to 95, did that too and the prints come out much better
First successful print!
@FrederikWeis: You are right. I'm from Germany ^^ but don't have Skype...
I changed some stuff in the configuration.h from the marlin folder of your github-version like steps per mm (really wrong values with 40/40/800/68), probe, bedleveling and some other points.
In my case it works. More tests tomorrow.
Ok if no one else can say me the steps I'll install the original version to look it up my self ^^
The steps should not be depending in the firmware. The value 'Steps per mm' says how much steps a specific stepper have to make to move one of the axes 1mm. So it depends on the stepper model and on the thread (or tooth distance of the belt) so if you got the same printer as me, the steps should be the same no matter what firmware.
Please give a hint if I'm totally wrong with this
I mentioned that x was 2.5mm crooked. Don't know why...
Without the belts I loosened the screws from the gantry and move the gantry against the carriage stoppers. In this position (after measuring) I fixed the screws again. After fixing the belts the difference is now about 0.4mm.
I think this is still much but after first tests I can't see "ghost steps".
@Frederik Weis Is it normal that I have to recalibrate the steps of all 4 steppers? Or have I chosen the wrong configuration.h?
Think x and y was 160 in my original setup don't know what z was but (it's now set) is too much ^^
Can anyone tell me the z steps please?^^
I'm at work for now but I'll try the firmware and some other stuff (higher current second time, xy- motors on z-pin...). I think the belt could be a problem too. I had no core-xy (or core-yx^^) before the proforge so I don't have a feeling for how to best get along with the two belts.
Again. I want to test if my x and y motors are OK. Z motors (and all 4 drivers are OK).
I could probably loosen the belts and connect x and y motor to z pins on on the board. If I than drive in Z both x and y should turn the same distance.
I want to test the steppers, not the drivers. The drivers are OK, I tested this yesterday and write this here (some posts up) ^^
