Instead of 1000's of words

Dear reprapers!
Don't wanna talk much, as I nervous right now after 5 days of getting this (see attached shots, please).
Please, give me a hint, what is wrong?
Repetier 0.91 + repetier host
mendel like self made steel frame etc

Looks awfull.

I have the impression that extrusion is not constant. Sometimes it seems to block and then you get more then you wanted. So first objective is to find why that happens.

You might want to clean your extruder in case it is clogged.
Also check if the temperature is right. For PLA you can go up to 220 if needed. Some want 200-210°C.
Clean feeder in case teeth are full of plastic.
Check if pressure of feeder is right.
Check thermistor type to make sure you see the temperature that is there. Different thermistors have different curves, so selcting the right one is important even if all have 100kohm at 25°C.

If the temperature is right and the feeder is not holding the filament (idler open) it should be possible to push filament quite easily through your extruder at a slow speed (still needs to melt so give it time for it).

Oh, thanks! I believe, that is was my mistake, hope this evening I will check the stepper driver, as stepper getting very hot (60+ C) and it 'ticks' and should work flowlessly
All other items will check tonight too
I will provide a link for video on my extruder at work before and after

Cheers

When a extruder ticks it is missing steps or slipping over filament. So the force is not enough to put it through the nozzle. Normally wrong temperature or clugged extruder.

Collegues, looks a little better, but there is a lot of things to improve.
ABS, looks like tempreture is not calibrated, excesive plastic etc

Those last ones looks like heated bed is set too high, try 90c

sorry, twice the same message

Thanks everyone for your help! Its now printing quite well. But some problems still there.
So, some shots:

First layer is always with excessive abs plastic, but second and others are good.

And few more - why some loses near holes? But near edges its okay?

The printer drags the filament on direction reversal back. Can happen especially if it did not make some contact to the border. Slicers allow to set how much overshoot the infill to border should have. Increasing it might help for better bonding here.

Thanks for a help, but I can not find where to setup this parameter. And I do understand, that's all my questions are not directly about repetier firmware/host. Sorry for this offtopic
