Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level

I just found this video

[www.youtube.com]

I'm going to watch this, but if it doesn't help, I'll try that.

Here is my Google docs sheet that will help you to calculate coordinates online - for probe points:
[docs.google.com]

Try to calculate 3 points for radius 50 and enter them in eeprom as z-probe x/y points. Then repeat G29.

So, that video only covers physical construction, not programming, but he's going to make a video about programming soon.
However, it turns out that my X and Z motors were switched. There is nothing in the instructions that says anything about the motor orientation being clockwise or counter clockwise, so I switched my X and Z motors. Not that that should affect my printer's ability to find G29, etc, because the towers are equidistant, and he said he was able to print (his prints were just mirrored) but that will probably help in the future.

Yes, it will print, but you will get mirrored prints. You had to check it first before starting to f%%uck my brain

Haha, sorry. But everything else is still the same. So that still doesn't answer why my printer would be acting the wrong way.

Move your effector in the middle, to be sure it's off endstops and copy-paste the results of your M119 and M205.

OK now when I type in G28, my motor makes quite a loud ruckus and causes that motor's belt to shake a lot. I tried it with both your Repetier FW and the old Marlin FW, resetting to m502, m500 each time.
NOW what's the problem?

If you switched your motors under live 12v there is a chance that you need new stepper drivers or RAMPS.

No, I unplugged it from both my computer and the wall

Is this Marlin output? Your z-probe is triggered, dude! You have to invert it in the firmware.

Nothing was triggered, so I figured that meant it was inverted.
If the endstops are engaged (The switches are pressed and the red LEDs are on) and I hold a piece of metal to the Z probe, (The red LED comes on) then type M119, the report is
x max triggered
y max triggered
z min open
z max triggered

So, I still need to set Z_MIN_ENDSTOP_INVERTING = true? Because it's set to false right now

Right, you have to invert your z-probe in the firmware. Normally it's open, with metal - triggered. It will fix everything.

No, that's what I meant. See I edited my last post. It's already set to false and all the others are set to true. So, do I need to make it true? Or just leave it as false?

If it's false - change to true, if it's true - change to false.

No, that still caused the motor to try and move past the endstop, causing loud noise the belt to shake.

Did you change all of them? You need to change only z_min.

My [www.thingiverse.com] stuff, my configuration of Repetier 0.92.6: [forums.reprap.org] (use Arduino 1.6.5 to compile)

Yes I only changed the Z min.

I just realized though, that the endstop has to be rewired too! I just switched the motor wiring, not the endstop wiring. I will do that now lol

I'm sorry, but I'm giving up. I'm searching a black cat in the dark room with you. You change firmware like gloves during our discussion. I thought we're adjusting my repetier configuration but you keep masturbating with Marlin. That's it, sorry.

Hahaha! Look I am really sorry. I know I am an idiot with this stuff and I know there has been some miscommunication, but you must understand, this is not only new to me, but also the way the G code works does not make sense most of the time. I don't get consistent results, even when I'm doing exactly as I'm told, and nothing significant has changed. Now, the hardware wiring change is on me, I just didn't put 2 and 2 together, but everything else having to do with the G code is not behaving as it should.
If you don't want to help anymore, I understand. I appreciate the advice you have given so far.
I'll let you know if I get it up and running either way.

EDIT: Also, I only change Firmware when I want to compare results. I change back whenever I make changes.

Alright, I promise from here on out, no more Marlin. ONLY YOUR REPETIER FIRMWARE.

The output is as such when no red LEDs are on and the printer is not plugged into the wall:

15:37:32.021 : endstops hit: x_max:L y_max:L z_max:L Z-probe state:H

The original inductive probe (with blue tip) needs 12v to work. So, switch 12v on and check z-probe again.

No Red LEDs on, EVERYTHING plugged in (printer to wall, printer to laptop)

16:11:54.283 : endstops hit: x_max:L y_max:L z_max:L Z-probe state:L

OK, now manually trigger X tower endstop and make sure with M119 that x_max:H.
Repeat for Y,Z and Z-probe.

Yes, each endstop responded with H when activated, same with the z probe.

I have to leave for now, but once again, thanks for the help (and patience). I will return tomorrow.

I use a combination of the paper test, and using the same principal (as suggested by paul_delta) I will often use a 2.5mm allen key to set the Z Home position. For the bed itself I went out and got three small levels (about 3" long, think they were "line levels") and leveled the bed to the world using springs under the mounting screws. I then use the G1 Z## F4000 command while at the edges of the bed to find discrepancies to adjust Delta Smooth Rod Offset.

I initially went through the same issues, and then realized the error in my thinking. Everything we read mentions leveling the bed as one of the first steps, and that is where the problem lies.

The goal is to have the effector parallel with the bed through its' entire travel. We can spend hours to level the bed to the world, but it is all meaningless if the effector can't replicate that.

Think of it this way: If I put a 1" block under one of the towers so it looks like the Leaning Tower of Pisa, I can still get the bed level to the world but I'll never get the effector parallel to the bed in this configuration.

I never used the servo arm that Folger provided, and eventually went the the dc42 IR sensor with the Duet controller. Same hardware configuration, no tweaks other than mounting the IR sensor. My autoconfig before printing takes a minute, I run it twice, and I get to 0.0x precision. Not saying Marlin can't work, it was just too much frustration for me.

Anyway, forget about leveling to the world. Get the bottom frame rails parallel, the bed flat on it, the rods equal length, and then adjust Marlin to get the effector running parallel to the bed.

I'm back. So, should the z probe be H (High) or L (Low) when triggered? Because mine reports High

All probes when triggered must be High. So, yours look OK now.
Turn it off, manually move effector to the middle of Z height, turn printer on and try G28, it should get home and then go down for 20mm from endstops.

It does, but it goes about 40 mm from endstops, not 20.
