Solved Hotend not close enough to the bed

Me again.

Now, I have a new problem.
I'm pre heating ok. As soon as the bed and the extruder have reached the pre-defined temperatures, the extruder first zeroing and then the bed level process is happening with good values. No big gaps in Z from one point to the other.
As soon as the bed levelling is done, the extruder moves up in Z for about 5mm and goes in XY position to start the print. Sadly, the extruder stays at that Z distance from the bed for the first layer and start to extrude material.
As you can imagine, this is a problem....

I have the ROBO3D R1+
E3D hotend.

The last thing I did, was to change the Max temp for the bed with arduino. I did not try anything else as I'm scared to Frack it up.

Any idea?

Thanks

Can you post your startup script?

Hi Tomer.
Not sure what you want. Do you need me to copy past part of the configh or

G28 ; home all axes
G1 Z5 F5000 ; lift Z by 5mm
M565 Z-1 ; set the offset for auto-leveling mechanism
G29 ; run auto-level

 

How do I make sure the micro switches are not out of place? They look Ok so far....
Any way to be sure they do their job correctly?
The interesting part being that I've been able to print correctly after the E3D install.
And yes, the Z axis is leveled.

 

Make sure you z-offset is 0

 

I had this problem too, for me easy fix. Just lift the x-axis and extruder and make sure that the hex nut is correctly positioned, make sure the x-axis has an equal high the the bed on both sides.

 

I did indeed have one of my nuts (left) way lower than the other one.
I did push in place the left side and did re try to print.



All centring and levelling Ok but still hot end starting to print with a Z at 0.45 like before.

Do I have to reboot/reset /something to make the fixed nut working?

 

Hey Geof.

G28; home all axes
G1 Z5 F5000; lift z axis by 5mm
M565 Z-1; sets auto-level z offset to 5mm
G29; auto-level

What do you mean by Matter control?

What I do not understand is that all G28 and G29 looks to work OK.... It's that it stays at .45 in Z for the printing...
My primary layer Height is set at 0.2000 (I've never changed that)

 

Sooooo.....
I did re install the original firmware with just the modifications for the Max temp and now it looks to work just fine.

Looks like it was something wrong with the update firmware for E3D called Robo3dR1V2_M8_E3D.

Finally, looks like I'm going to be able to print with my printer. Crossing my fingers and lighting magic candles to 3D printer gods.

Thanks again guys for being on the case.

 

I have the R1+
