DELTA leveling issue.

I am Dipen, I have built a delta 3d printer at home and i am having problem with leveling, my origin(nozzle point) at (0,0,0) is staying 10mm above from the B(0,102,0),C(-88.33,-51,0) and D(88.33,-51,0) towers points and I have attached my configuration file with this post and G CODE command M665 is not working in pronterface , so please help me out here i am using marlin firmware. I am stuck there.

Run these and report back with your M114 values.

1) G28
2) G1 Z10
3) M114

How close is the nozzle to your bed after this?

Hi MrMeeeseeeks, thank you for your reply after sending G1 Z10 my readings are as below mansion;

How far is your nozzle away from the bed at this point?

My nozzle is at exact 20mm from my bed.

Okay. Go into your Config file and edit this value #define MANUAL_Z_HOME_POS 280 and add 10 to 280 making it 290. Re-run the first test. Report back if the nozzle is closer.

now at the origin(0,0,0) my nozzle is touching the bed but when i move the nozzle it,s hitting the bed.

Okay then it isn't 20mm away. In the Prointerface you need to manually move the nozzle away from the bed. Start with 1mm then .1mm. Keep a count of these values because you'll need them next. You know what the paper test is right?

You'll controll that by using this:

i am getting convex print surface and the height difference between the center and end of print radius is 10mm.

yes i know the paper test i did it

Attach a picture so I can get a better idea of what you're talking about. Is your bed bubbbled or something? How is it convex?

I was thinking the "printed" surface was convex, not the bed itself. So he was 10mm off in the center but spot on at the towers. In that case, he likely needs to adjust his print radius and repeat the paper test (assuming this means adjusting the endstops at each tower).

But I am not completely following the conversation, mostly just what popped in my head as I was reading / skimming.

i have attached images with this massage, which shows at the origin my nozzle is fine but at the towers my nozzle is around -10mm.

Try using the steps on this blog to calibrate your printer. Essentially you adjust the endstops at tower A, then tower B, followed by tower C until they are all the same height. Next you check the height in the center of your build area, adjust the delta radius (printer radius?) of in your firmware by -2.2 the distance you are off at the center. Repeat the tower endstop adjustments and delta radius adjustment until your printer is flat.

@MrMeeeseeks and @Kurzaa will you please tell me how to find the values of z probe and and endstop... i am new to 3d printer...

// Z-Probe variables
// Start and end location values are used to deploy/retract the probe (will move from start to end and back again)
#define Z_PROBE_OFFSET {0, 10, -5.6, 0} // X, Y, Z, E distance between hotend nozzle and deployed bed leveling probe.
#define Z_PROBE_DEPLOY_START_LOCATION {20, 96, 30, 0} // X, Y, Z, E start location for z-probe deployment sequence
#define Z_PROBE_DEPLOY_END_LOCATION {5, 96, 30, 0} // X, Y, Z, E end location for z-probe deployment sequence
#define Z_PROBE_RETRACT_START_LOCATION {49, 84, 20, 0} // X, Y, Z, E start location for z-probe retract sequence
#define Z_PROBE_RETRACT_END_LOCATION {49, 84, 1, 0} // X, Y, Z, E end location for z-probe retract sequence

#define AUTOLEVEL_GRID 24 // Distance between autolevel Z probing points, should be less than print surface radius/3.

when i did paper test these value i got now i don't know how to correct this,

Here is a good video on how to calibrate, it deals with the issue you have (delta_radius): [www.youtube.com]

Here is also a good site covering a bit more for calibration: [delta-calibration.s3-website-us-west-2.amazonaws.com]

@Koenig...thank you for you reply...
i had tried to send M665 but this command is not working, its showing only "SENDING..."

@dipenjungi

Run M501 that shows all the Gcode commands that store values in EEPROM.
If it doesn't show M666 in the list, you need to install Marlin firmware that supports M666.
