Welcome to the SeeMeCNC Community

Hello!
Have a couple issues I'm trying to solve as they're a tad tricky. I just got the Orion Delta and am trying to print. Printed a few test files flawlessly over and over just to show off the printer. But now I've gone through the complete setup of repetier. I am able to successfully slice my files and have the Orion execute the .gco file...however the leveling seemed a bit "off"...and now begins my journey :p

The test files "blinky" and "fan" seemed to print okay, but the bottoms weren't smooth like the one sent with the unit (stuff probably shifted during shipment.)

I carefully calibrated the Z with a set of feeler gauges at .1mm in @ 0,0 dead center of the plate.
For some reason though, all my parts would be very thin on one side, then slowly thicker to not adhering/peeling on the other side.

I figured the leveling script was the issue...from my understanding it was take 3 points on the bed with a piece of paper pinched and hit calculate level within the menu.
Whoops.
I calculated 3 points on a triangle @ 60mm radius. Then I went into the menu and hit "Set P1, Set P2, Set P3,"
I would re-home the extruder after every "set Px".

I ended up having very different numbers on the Z prompt when the gauge was "pinched" by the nozzle tip for each point. (For instance, one of them was -0.31!)
After each point was set to be barely pinching the feeler gauge, I hit "calculate level"
Now I try to run a radius calibration print included on the sd card; The nozzle kisses the glass on the far left corner, and appears to be suspended well over 1mm on the far right... From my research on the forum this is a phenomenon called "lensing."

That's where I'm at so far...no idea how to "un-level" it back to factory defaults which albeit were't the best, they were damned better than the calculated level that I've performed...

I'd appreciate some info on;
How can I "reset to factory defaults"?
How do I apply the "lensing" fix on the Orion Delta?..was my leveling procedure incorrect somehow??
Thanks for all the help! Looking forward to seeing one of my own prints on the build glass. This printer seems so nice I'm itchin' to use it.

If you didn't keep the original settings I don't think there is a way to go back to a factory default (each machine needs individual calibration).

At this point if you can't get back to the original settings and you can't print with were things are now I would suggest looking at the Rostock Max manual for the calibration sections, they go step by step how to calibrate the printer (though note that the gcode needs to be altered to take into account that the orion is much smaller).

THanks!
I have definitely been going through the Rostock manual as well which is where I found out about the lensing/doming issue.

When I go in and set P1 P2 P3, are those referring to certain towers? Because I just arbitrarily assigned the lower left to be P1, mid top to be P2, and right to be P3. I just realized in the write-up for the ROstock that the towers are assigned with degrees...if I "choose poorly" would that cause the calculate level to be totally off?

Hello Again,
I've been at it for quite awhile again..progress!

I have successfully:
Flashed the firmware using arduino using the EEPROM>Clear command then uploaded Repetier 0.91 Orion pkg using Github.
The versioning on the LCD has definitely changed and is up to date.
I have not touched anything but the Z-level (calibrate) and it still has the same problem as before.

One interesting issue that I noticed in the new firmware is that it has some sort of very short time-out for the stepper control. I guess I'm too slow at doing the Z plunge; by the time I had it done, the steppers had disabled themselves and my extruder came falling down on one side..lol.

THE ISSUE: Still can't print. I still have an extremely close nozzle on the left side (But the mid to right side is now fixed and level!)
I've been pouring over the rostock docs still and looking anywhere for how to solve this. I measured the distance from the platform (not the heated bed/glass) to the top of the cheapskate bearing sets. The Middle and right towers are EXACTLY the same distance., but the left tower is like an 1/8th LOWER (AHA?!)

Adjusted the endstop screw but it doesn't seem to be doing anything. Anyone care to help shed some light on the issue? I have to pack this thing up for a show soon and have yet to print our own stuff I don't want to have to have this thing sitting on a table without it printing :-\

*edit:

Re measured and adjusted. I got it to stick! Calling it good for now. Time to try my own prints...whew.
Thanks everyone for your help.

On a high note; The orion is indestructible!!! ...and now perfectly leveled (Upgraded from "GOOD")
Sent a G1 X-700 Y-40 Z0 command at 4am. Seriously, I suggest having your cat recheck your gcode if you write it at this hour. Tried putting the gantry about 5 feet to my left and behind me. The effector arms came flying off and the nozzle plummeted to the bed. After I picked my jaw up of the floor and shocked my heart back to work I just clipped everything back in place...ZERO damage. THANK YOU for the clip design on the effector arms.

Leveling: I noticed you removed the level delta from the firmware completely. Good call!
Somehow an epiphany came through a cloud of stupidity and we realized there is no possible way to level 3 towers with the nozzle in the center....accurately. Glad I read through the code on the various functions. "Software level" is new to me. I have no idea how but this piece of info was lacking in everything I checked.

I corrected my scripts and set;

;#1
G28
G1 X-61.3 Y-40 Z0

;#2
G28
G1 X61.3 Y-40 Z0

;#3
G28
G1 X0 Y60 Z0

G28
G1 X0 Y0 Z0 ;cross yer fingers

After this I was able to immediately see the direct results of the end-stop screw change. Using a feeler gauge @ 0.1mm I then set all 3 towers and adjusted their end-stops on their given towers.
I can't tell you how exciting it was to see the nozzle do a sweep across the bed and not impact on one entire half, and not be a mile away on the other side. Don't get me wrong I was fine with printing Blinky's for the show

I then noticed the nozzle high in the center after running G28 X0Y0Z0. Referenced that handy gcode file you uploaded with the instructions on horizontal radius. Saw it was high, increased the horizontal radius from 74.3 to 74.4...it kisses the center, just like the rest. YES!
I can run it anywhere on the bed now and the height is exactly the same. We immediately crunched a large surface area custom file and had it print. Success has never been so sweet and rewarding

Mortinus- I'm trying to adjust my horizontal radius and I'm not observing a change. Mine is pinning the paper down and no matter if I increase or decrease, the paper is still stuck. Have any ideas?

The horizontal radius effects the relative height of the outside radius to the middle, which may push the center further down. You need to adjust the z height with each iteration.
