Printing: Damn corners..
Hey guys,
Just had this problem for a while and thought to ask you guys if you perhaps had a solution,
whenever i am printing 90 degrees corners seem to be such a problem,

Its like always a slightly bow form in it..
I first thought it might be my Y bed that has like a wiggle in it, But Colin said thats normal (Makerfarm support)

Well hoping you guys have a solution ^^
Thanks for the help!
Best regards,
Luigi

Hi Luigi,
Perhaps lowering your acceleration settings in firmware will give positive effects.
At what speed have you been printing the perimeters, oh and which firmware do you use?

Hey,
Well it should be 60mm/s as printer goes,
And i believe accerlation is like 1000.
Here is the config: https://docs.google.com/file/d/0B80A...it?usp=sharing
its the same one as Makerfarm suggests.

Whenever we come across problem prints, we try to go back to basics first. What have we changed lately and could that be the cause? Are we pushing out too much plastic (or too little)? I am often guilty of putting on a new color filament and just assuming that it is the diameter as the last one (geez, how many times my son scolds me for this?) Temperatures too hot (or too cold)?

Well i think i realy always had this problem but kinda tryed to ignore it till now that i kinda wanna try to resolve the problem :P
I guess it may be that the E axis isnt pushing enough so i changed the steps it does from 841 to 899.8.
It seems better now and i will make a pic of it when done. not sure tho

I have to say it, sorry but it still looks bowed to me. I had a similar problem back when I first started in 2010 and at that time I slowed the print speed down to 40mm/s instead of 60 and it fixed my prob. I've since changed firmware to Repetier and I've not had the problem since even at 60mm/s, I was using Sprinter and have gone through using Marlin ok too.
If you can't fix it in firmware try playing with the settings in your slicer but keep a note of what your changing, there's nothing worse than altering your settings, finding it doesn't work and you've forgotten the original settings.

Excessive speed or too high acceleration can be cause of this issue. I had similar problems with Sprinter but after I moved to Marlin and found speed that works well for my device prints are fine now. I also have accelerations set to 750, but machine I am using is my design so I can't guarantee it will work for you. Also decreasing speed is a good idea to, even if it won't help you will eliminate one of the possible reasons.

well i will try this: http://www.thingiverse.com/thing:24238
with 30mm/s :P
argh so slow xD
Edit:
Well Makerfarm made the E axis 841, But this was without a HotEnd (Well also when retracting it was always spot on, when i did a measurement)
But with HotEnd its just not extruding enough.
So know i did it on 926.8 and it seems to be correct again,
Maybe with a all metal extruder there is less friction and it might need to get changed again then,
But ye i aint sure if i should buy one or not ^^
Btw its printing at 40mm/s almost done ^^Last edited by DrLuigi; 10-29-2013 at 03:56 PM.

Okay,
After a 20ish minutes its finaly done,
Imo its better now ^^
the object is 2.5 on 2.5 on 2.5cm, with 0.3 layerheight if i remember correctly,
Kinda proud on my Phone's camera to get a few nice shots xD

Keep in mind, the 90 degrees may not look stunning, its a very small object :P (well 2.5x2.5x2.5 cm :P)
