DC42, Thanks for the answer. I have tried the calculator about 6 times with different points and always get this: M665 RNaN L240.00 M666 XNaN YNaN ZNaN ; Set homed height NaNmm in config.h. (I do have 240mm rods) Not sure what is wrong. I have tried to manually enter a correction with M666 and nothing changes. I am trying to do it in Pronterface, I have read somewhere that does not work. When I try in Repetier the EPROM screen is blank and says it only works for Repetier firmware, the printer is Marlin yes? What am I doing wrong here? Thanks for any help one can give me.

Now I am thinking of starting over with Repetier FW as it seems it would more easily address my problems. Is there a guide or source to setting it up for the FT RevB? The page has a ton of questions. I did download Communication.h from paul_delta. Anything else I need or need to know? Thanks again.

OK, have the new firmware installed. Now is the a guide or anything on how and what files need setting up? Thank you for your time and patience, New to all this.

Below is the last one I ran. Previously I entered the coordinates to stop in front of each upright and stop between each upright and then center, So no two spots were the same and it covered the whole bed. Same output of calculator.

Something else fyi: I tested the inductive z probe (the LJ12A3-4-Z-BX) and was astounded how *bad* it actually is. On different positions on the bed I get a deviation of up to 0.3 mm between the nozzle touching the bed and the probe triggering (possibly because of the PCB below the aluminium?). To make things worse, the LJ12A3-4-Z-BX is temperature dependent. I cant get any realiabe mesaurements and autoleveling done.
I will upgrade my Kossel2020 RevB with some stuff to make (auto) leveling a bit easier (JCRocholls touch probe, glass bed surface and spring loaded bed support) and post pictures & results.

09zx-6r: Depends. Kossel2020 old version or RevB version? Firmware is Marlin from Folgertech?

I have been enjoying reading posts of this forum and thanking all of contributors.
Recently I have finished building a rev B printer and having fun with it. After careful measurements and calibration a 20mm cube was printed for testing. As shown in the attached picture, the cube is not straight but tilt along Y axis. I have found that the radius value is slightly different between the three axes (within 2 mm), and suspecting as a possible cause of the tilt. I would appreciate for any suggestions and guides. The Y axis is along the left to the right.

I do need serious help for my printer. When everything is reset, it prints well. But when the printer is continuously used, layer deposition is shifted to one side as shown in the picture. This problem goes away when the machine is reset. Is it possibly caused by the controller? Or some mechanical problems? The attached picture was taken in the morning when the printing was left unattended during the night with confidence, it was a total mess. It seemed OK till 2 layers were printed and prints before the pictured one were OK.

So, I'm trying to print this:
but I'm getting this:
Notice how two of the outside points are missing? It doesn't look like that in slicer nor in pronterface. Any ideas why this is happening?
I notice that the problem is in line with one of the towers (I have it arbitrarily labeled as "Z"). I have "circular build platform" checked and the Width/Depth are set to 172mm. X&Y Offsets are -86 and the print across the diameter (without the points) is coming in at 152mm so I should have 20 more mm of travel.

I had similar situation when nozzle touched warped side of model during travel. Check your extrusion rate, speed and temperature.
BTW did you check your drivers vRef voltage? Probably one of motors skipping steps.

Paul_delta,
Thank you for the reply. I have checked the vRef and they are ~0.65V. Only Z-axis motor is bad (along the '-y direction' on the bed), and other axes are 'OK' compare to the Z-axis. The behavior is consistent with that the Z-motor is not strong enough to push the carriage back to where it has to be. When the motion is limited near the center the effect is minimal, but when the stroke is long enough the shift is significant. Since I have three stronger Nema 17 motors, decided to replace all three at once. I will see the result tomorrow. I remember seeing complains that those stock motors are not strong enough for the supposed function. I will report what will happen after the replacement.
One good thing I got through the trouble is deeper understanding of the printer.

Try to swap driver boards, like X-Z and see if the problem will move to another axis.
Check your top bearing for problem axis. I had to reassemble one of them because it was too tight.
BTW the vRef is 0.35v for stock motors. I have stock motors and they work up to 120mm/s without any problem.

Try to move your hot end manually to the problem point. Are you able to do it without skipped steps?
Is it Repetier? If so, what is #define DELTA_FLOOR_SAFETY_MARGIN_MM ?

I finished building my kossel. I got tired of waiting for folger to send me the missing screws, so I sourced them locally. It was a good thing I bought an assortment, because the manual is full of errors in the called for screw lengths. Anyways, I got it assembled with no issues at all. It's "square". After completing the wiring, I dialed in the stepper driver Vref, and moved on to the firmware.
Oy Vey! What a nightmare! Well I think I half figured it out, enough to home the printer successfully. I'm using repetier with the firmware provided by folgertech. I think I made most of the modifications necessary to get started calibrating it.
My issue is with the inductive sensor. It appears to function, as the LED lights when in proximity to the bed. The arduino doesn't seem to see a signal from it. Is there a setting in the configuration I have missed? I know I wired the resistors correctly, and I am sure it is connected as shown in the diagram in the manual. Knowing that though, I still don't actually understand how the thing works, so I'm not quite sure how to test the hardware. If I want to test it, what should I see at the arduino connector, when the sensor is "open", and "closed"? Is it as simple as that, an open or closed circuit? The weird resistor circuit makes me think it's not so simple.
I about threw the thing out the window last night, but slept on it instead. I'm ready to go back at it with a cool head, but I'd like a little guidance. I tried to look into doing the bed leveling manually, and it makes my head spin. If I can't get this sensor working I will have to let it sit until I can improvise another auto leveling solution.

Try to load this Repetier firmware [forums.reprap.org]
It's pre-configured for FT Kossel.

I tried using that one yesterday, and again just now. It won't compile for me. Here is the error I get in arduino when I try to verify it:
"
sketch\libraries\twi.c:1:17: fatal error: twi.c: No such file or directory
#include
^
compilation terminated.
exit status 1
Error compiling.
"
Sorry if I'm missing something simple. It's been a while since I've been so humbled by a piece of equipment. It's maddening.

Ok thanks Paul, I used an older one and it compiled. Seems like the same thing though. I run M119 and the z probe reports the same thing whether it's triggered or not. Looks like I may have a bum probe, or I wired it wrong. I guess I have to learn to calibrate it manually. Shoot me now.
