Latest Benchy calibration print at 0.15mm layer height, 15% infill, no supports... all measurements are within +/-0.02 tolerance, except for port holes, which are a little small (I'm having this problem with screw holes on other prints as well, still haven't figured it out).

What was your settings in s3d?
Ive been calibrating my x axis and Have it as close as I can get it. my y axis is right on. im wondering if the x axis should have had a bigger oz stepper like the y axis got? That little motor is doing alot and mine gets pretty warm.
What is your first layer height and speed? Im very curious of all your setting. Where im still learning. I have my first layer height at 90% and speed at 35%. Im thinking about trying 100% and maybe speed up to 50%

Sorry to be bugging you all but I'm about to throw the electrons to my 2020 and I have a question about the pots on the polo drivers. I wanted to turn them all down to zero to start but I just found out there is no stop when turning counter clockwise! How do you know what position is MINIMUM? I can, I believe, see a wiper close to the top pin when the flat is facing down. All pots came with the flat facing left when the board is mounted with the power inputs to the right.
use a multi meter.....
I know that!
I just don't want to power it on with the pots set at max and immediately fry the drivers. I just watched a pololu video where they tell you to adjust these values BEFORE hooking up the motors, which makes sense so I will be disconnecting them. HOWEVER, do you know if our drivers are Pololu, Stepstick, or Chinese knockoffs, all of which use different sensing resistors and therefore different REF voltages? I'm off to see what resistor value I can see.

Ok X axis issue resolved.
Ok if your like me and put the printer together by the book, then your probably going to have and issue with your x axis moving just a little and in the wrong direction. Im a noobie to all this and it took me awhile to figure all this out and a lot of reading. Hopefully this will save some people some time.
HOW I GOT THE X AXIS WORKING THE RIGHT WAY.
1. With no power plugged into the board swap your x axis motor wire around from what folgers shows in there build. Have the red wire facing towards the usb cable just like the others (Z and Y) are.
2. open up your marlin ini file in arduino. Click on the "Configuration.h file"
3. Scroll down to where is says "Mechanical Settings"
4. Then scroll down a little farther until you find "End Stop Setting"
5. Where is says
#define X_HOME_DIR 1
put a - in front of the 1 so it looks like this.
#define X_HOME_DIR -1
6. close out the arduino box and it will ask you to save your settings and Thats just what you should do.
7. Now reopen the ini file in your marlin folder and click on the arrow up top pointing to the right to upload the firmware you just changed into the board. after its down close down the arduino box.
8. Unplug the usb again and make sure your x axis reset switch wire is plugged in the last set of prongs on the board (this should be already like that as its the way folgers shows you in there manual).
9. in repetier make sure in printer settings the x is set to max and y and z are set to min.
Now give it a shot! If this helps anyone we should make it a sticky or something. Seems like alot of people are having this problem which really should be corrected by folger tech in the first place.
Sure enough, my X was backwards! Why doesn't FT fix their instructions???? The only thing I DIDN'T do was your one step where it says in Repetier to set x to max. Do you mean to reverse the 0 and 200 settings?
EDIT: I did go ahead and swap the X coordinates. I homed and got the G90 code, meaning I am at absolute coordinates relative to home.
Now, when I try to move using Repetier's arrows I get an error message saying 'printer stopped due to errors'. Back to searching. I'm close and NO SMOKE so all is good!

What error is it showing? Have you tried putting x axis to max in the repetier software and trying it?
