Kossel Delta xxl build project HELP

Thank you FA-MAS. I'm going to do that tonight and report back

Something it is not right.
I powered up the printer on,I homed it with G28 command, moved the nozzle up to 5mm above the bed then I ran G30 with no parameters, then I ran G32 command for Autocalibration.
When I ran the G32 command the head went up to home all position then when it went down it crashed on the bed and moved towards the bottom of the Y tower.
This was what I had in Config.g for Z-Probe :

; Axis Limits
M208 Z0 S1 ; Set minimum Z

; Endstops
M574 X2 Y2 Z2 S1 ; Set active high endstops

; Z-Probe
M558 P5 R0.4 H5 F1200 T6000 ; Set Z probe type to effector and the dive height + speeds
G31 P100 X0 Y0 Z-0.1 ; Set Z probe trigger value, offset and trigger height
M557 R100 S20 ; Define mesh grid

I'd say at least for now, in your M558, lower the T parameter, right now it's 100 mm/sec. I lowered mine to 30 mm/sec aka T1800

The probe points are in your bed.g
The reprap firmware configurator chooses them based off of the probable radius you enter. Post your bed.g

Looks like you're not probing anything more than a 100 mm radius.
Remove that G28 from the bed.g
You'll also want to use at least 10 points for 3 factor to be as accurate as possible.

Something looks off to me in your movement section with the motors moving backwards.

My question is, it moves the way it needs to when you move it correct?

Aka,
Z- buttons move the nozzle away from the endstops, Z+ buttons move it towards the endstops
Y- buttons move the nozzle toward you, the Y+ moves it away
X- buttons move the nozzle to the left, X+ moves it to the right

When it's near the bed, the Z position reported in the web interface is nearer to 0 than when it's away from the bed?

Home All button moves all 3 carriages up toward the endstops and they stop when triggered?

I removed the G28 from the bed.g.
The T parameter in M558 is T6000

All buttons are doing what you said.

Should be it, probably that G28

I'm going to try again and I will report back.
Thank you

Thank you so much.
IT IS WORKINGGGGGGG.
How I can change the probing from 100mm to the maximum radius ?

You tweak the probing points in bed.g

I would tweak yours like this.

G30 P0 X0.000 Y149.000 H0 Z-99999

G30 P1 X129.037 Y-74.500 H0 Z-99999
G30 P2 X-129.037 Y-74.500 H0 Z-99999
G30 P3 X0 Y0 H0 Z-99999 S3

I would also update this in your config.g

M557 R100 S20 ; Define mesh grid

Make it R149

Thank you so much. I did change per your instructions and it is working. Can you please help me to set it up for 6 factors with at least 18 probe points. I'm so happy. Is moving.

The configurator at RepRapFirmware.org can generate the bed.g file for you. There is also a bed.g generator at [escher3d.com].

I've plugged your printer's details into the configuration tool and here's the bed.g it made.

Thank you so much David.
It is working. I love this machine. I'm so close to print with it.

Thank you so much FA-MAS. It is working.

I have a deviation before 0.028 after 0.025
Should I be worry about this difference ?
What should I do next ?

This is the the first Mesh Grid Heightmap with the Bed and Hotend off.

Edited 1 time(s). Last edit at 05/10/2019 03:51PM by alex773.

That’s about the deviation that I’m getting. I’m getting 0.033 while using 3 factor and as low as 0.01 with 8 factor. I’m getting awesome first layers. My understanding is that as long as your deviation is lower than the height of your first layer, it should be good. I’d say set up a Slicer and print some stuff.

That's a very good news. Thank you FA-MAS.
Do I have to change or save something in bed.g. Config.g ?

Totally up to you, if you wanna see what the deviation looks like, you would change the last line in your bed.g from S6 to S8

I'm going to try later to change something.
Thank you

Something I not going right.
When I turn the printer on the hotend temperature it is 38 degree C , but the hotend is off and cold . I checked the connection and everything looks good. Where is the problem?

Probably in the M305 P1 command in your config.g file. What temperature sensor are you using? Please post your config.g file.

Thank you David

Your config looks OK. If you are using a 2-wire Pt100 connection, then I suspect that you have excessive resistance in the wires and connectors between the daughter board and the PT100. An extra 5 ohms would give a reading around 38C.

Thank you David for your input.
If you remember in first place when I first started the printer the difference between the bed and hotend it was almost 4 degrees C.
There is no option to fix this problem ?
Thank you

If the connections in your PT100 wiring have 5 ohms resistance, you have at least one bad connection. Compensating for it would be foolish because the resistance won't be stable.

If you are using very long or very fine wires to the PT100, then either use thicker wires or use a 4-wire connection.

I guess the other possibilities are that your sensor is faulty, or the daughter board is faulty. You can test the daughter board by connecting the supplied 100 ohm resistor to it in place of the sensor. It should give a reading very close to 0C. You can test the sensor by connecting it directly to the daughter board, bypassing the wiring.
