I just can't get this thing calibrated to print even close to what I want it to print at. None of the parts are usable as they do not align well at all to the drawings. Everything is slightly too large.

Can you use PronterFace to make it move? Does it move the correct amount of distance in ProterFace?

If you have the option in your slicer have it do perimeters first then move in. That will help combat the sizes being overlarge

It is frustrating. At times they are off by .5mm other times they are too small. I went through, cleaned, and tightened everything. Hopefully that will help even though I didn't find anything loose.

Parts is still do not have a finished appearance. I'm going to try some different filament. Maybe that may help.

Unless you need the heat resistance I would recommend switching to PLA, it prints much better than ABS in my experience. The only ABS I have tried though was two rolls that I bought with the printer kit so different ABS may print better than what I got with the printer.

Do I need to add part cooling fan for pla?

Not unless you are printing small parts, where your layer times are really short. Before I added my cooling fan I would just print multiple small parts so that layer times were manageable.

So I finally was able to get around to set up my ABL. Everything is hooked up with servo and working fine to find the position for the servo arm. So when I go to home the x or y axis it moves away from the enstop. But in proterface all the axis move in the right direction. I am using tsteever's frimware he uploaded.

Hmm, wish I could help more. What happens when you home using the lcd? How about safe homing? Do you have that enabled?

So its only the x axis that moves the wrong way. If I tap the endstop with my finger it will stop while moving. Everything else works fine y axis moves the right way and the probe arm for the z ABL drops and homes perfect.

Was the printer working before you loaded the firmware for the ABL? Sounds to me like you need to turn the connector for your X motor 180° so it will move in the other direction.
