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.

If you get NaNs in this answer, this generally means that two or more of the XY coordinates you have entered in the calculator are the same. If that isn't the case, please post a screenshot showing the values you used.

If in doubt, choose 4, 7 or 10 points and ask the calculator to suggest the XY coordinates for you.

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

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.

The reason that the calculator is generating NaNs is that the combination of diagonal rod length, delta radius and probe points you have entered is physically impossible, because the arms would be too short to reach the first probe point. The calculator doesn't check for that. My guess is that the delta radius of your printer is much lower than the 186mm that you entered, more like 120mm. What value do you have set in the firmware? If you are running Marlin firmware, then it's the parameter called DELTA_RADIUS, and it is calculated (quite unnecessarily IMO) from some other values.

Yes, here is my post about this problem and discussion: [forums.reprap.org]
It was the main reason why I designed this probe holder: [www.thingiverse.com]

It's much easier to level the bed when the probe has zero XY offset from the hot end. Also, to make it working with glass covered bed, I made a simple adapter that converts inductive probe to non-inductive [www.youtube.com]

PS: actually, the probe is not bad - it has very good precision and returned values are pretty stable (during not very long z-probe session). During heavy tests I never had an error more than 0.01mm. And I suspect this error is just a backlash of mechanical parts and probe mount.

i have the FT kossel2020 Rev B with the marlin FW from Folgertechs site...my inductive probe works fine... but i have yet to be able to get the flatness setup correct... theres a program called Matterhacker controller, i use it to autolevel my other 3d printers bed with NO probe needed... its the paper test at 3-12 points depending on how exact you want it... but iv never had an issue since... i may forgo the inductive probe and set a tall Z height and do it thru the software instead...

but either way, id like to try the correct way first... easiest isnt always the best way...

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.

I also need a recommendation for a 32 bit controller upgrade?

Thanks in advance.

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 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.

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.

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 ?

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.

The motors were barely warm at 0.65V so didn't bother to lower them. It seems better practice keeping them as low as possible. I will try that. I also have 2020 i3 there I tried to lower them to be 0.35V and no troubles. I will certainly check the top bearing of the troubled axis. I think it also is a good idea to check the driver boards by swapping, too. I wish I had all the good suggestions before replacing the motors. If the top bearing was the problem I may have the same trouble with replaced motors. I appreciate for the suggestions.

It's not Repetier, but since you guys seem to use it more, I just tried to install it and I got this when installing:



So, if anyone has any ideas why I can't install that software.... maybe it's a funky port? I don't know why it's trying to go online when installing since I didn't check the skinforge box, which, supposedly, is the only part it needs to go online for (there's a warning message there about needing an internet connection, which I obviously have).

I scaled down the print by 10% and am printing it successfully now.

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.

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.

Check your wiring. BTW you have to learn how to calibrate anyway. Z-probe is a useful tool, not a panacea.
Also you can try to use dc42 calculator - fill your values, measured using paper test for 7-10 points and enter results in your firmware (using Repetier Host Eeprom menu)

PS: may be you swapped ground and signal pins from z-probe to RAMPS? BTW you can check z-probe with multimeter connected to ground and signal pin. Disconnect from RAMPS and measure voltage, switching z-probe on and off with piece of metal.
