Autolevel - Z axis crashes into bed!!

garfield30 · August 2017

Hi,

I am experimenting with the auto leveling. I am using the latest dev version of the firmware but I have a problem. When I home the z axis it homes all three but the worst of all is it moves down on the z axis until the induction sensor triggers it then moves up as expected and then comes crashing down into the bed!!

Please help as I am at a total loss

Thanks

I was trying to attach my config file but it doesn't appear to let me

At the end z probe offset, bed coating and distortion correction gets added. So if these sum up to wrong height it can in deed crash. If you do not have multiple surfaces set bed coating 0 and adjust z probe height to be correct.

garfield30 · August 2017

Thank you. I've checked and I have Z_PROBE_BED_DISTANCE set to 10 and Z_PROBE_HEIGHT set to 0. Wouldn't that move it away from the bed though?

MartinH · August 2017

Z_PROBE_SWITCHING_DISTANCE this is preset to 1, this may not be enough to un-trigger the probe.
set it 3 or 4 to make sure.

Repetier · August 2017

Also z probe height 0 is normally wrong if you have no force feedback sensor. It is ditanve nozzle to bed when sensor triggers.

garfield30 · August 2017

thank you all for your help. Unfortunately it is still doing the same thing no matter what values I put in the options. The switching distance was already at 3 so I increased it to 4. I have tried changing both the bed distance and z probe heights to higher and lower figures, but it is still doing the same thing.

Another thing which doesn't seem right is that when I home just Z it still homes all three

Roko · August 2017

Did the machine work before you tried autolevel? What type of machine is it? what about homing x or y only? can you copy/paste your configuration.h?

garfield30 · August 2017

Yes the machine was kind of working before but i've been having problems keeping the bed level which is why I wanted to try the auto level. the machine is a hictop prusa i3. X and Y home ok but as mentioned above they also home when I click the home Z only in Repetier client.

Please find my config file below.

Thank you for any help you can give I really want to get this working if possible

If the firmware is in laser mode, it can control a laser output to cut or engrave materials.

Please use this feature only if you know about safety and required protection. Lasers are

dangerous and can hurt or make you blind!!!

The default laser driver only supports laser on and off. Here you control the intensity with

your feedrate. For exchangeable diode lasers this is normally enough. If you need more control

you can set the intensity in a range 0-255 with a custom extension to the driver. See driver.h

and comments on how to extend the functions non invasive with our event system.

If you have a laser - powder system you will like your E override. If moves contain a

increasing extruder position it will laser that move. With this trick you can

use existing fdm slicers to laser the output. Laser width is extrusion width.

Other tools may use M3 and M5 to enable/disable laser. Here G1/G2/G3 moves have laser enabled

and G0 moves have it disables.

In any case, laser only enables while moving. At the end of a move it gets

automatically disabled.

The only parts of your config i can see that i would change are the
homing order , pre raise options, and Z homing locations as below

#define HOMING_ORDER HOME_ORDER_XYTZ

#define ZHOME_PRE_RAISE 2

#define ZHOME_PRE_RAISE_DISTANCE 4

#define ZHOME_HEAT_HEIGHT 10

#define ZHOME_X_POS 100

#define ZHOME_Y_POS 100

The rest looks ok.

garfield30 · August 2017

Thanks Martin. Unfortunately it is still doing the same thing, only now it's in the middle of the bed

garfield30 · August 2017

Does anyone have any ideas please? I really don't want to go back to manual bed leveling every time I print

Repetier said:

At the end z probe offset, bed coating and distortion correction gets added. So if these sum up to wrong height it can in deed crash. If you do not have multiple surfaces set bed coating 0 and adjust z probe height to be correct.

So, if you were to go to Z=0 using the manual control panel in RH it would stop at 0? Lets say you do a G1 Z10 and incrementally go from there to 0. with autolevel data cleared it should stop at 0 (not going through the bed) if the stop is seen since you are homing to min.
you also have ui_bed coating set to one,is that correct?

Thanks Roko,
I wasn't sure what to set the bed coating to. I currently have use Buildtak so it isn't very thick. I have also tried setting it to 0 but the same result.

The other suggestion you made works fine. I did the G1 Z10 and I was able to move down to 0 again.

recoush · August 2017

Sorry to butt in but i noticed two things

1

#define MULTI_ZENDSTOP_HOMING 0

is this supposed to be zero

#define DRIVE_SYSTEM 0

#define XAXIS_STEPS_PER_MM 160

#define YAXIS_STEPS_PER_MM 160

2

#define ZAXIS_STEPS_PER_MM 805 //836

never seen a 805 // 836?

not sure if this has anything to do with it

just noticed is all

Autolevel - Z axis crashes into bed!!
