No Calibration and no compensation….Grrrpffddsdf!!!!!!!!!!!

dc42

The distance we need is the height of the nozzle above the bed when all 3 carriages are triggering the endstop switches.

peirof

Distance… 505 mm

dc42

So you need H505 in the M665 command, not H550.

Dougal1957

ok in that case you have an error in your Config.g

This line M665 R165 L360.25 B175 H550 needs to be M665 R165 L360.25 B175 H505

Also until you have it successfully calibrated comment out the M501 line at the end

peirof

ok…

later try...

This, change [c]M665 R165 L360.25 B175 H550[/c] for [c]M665 R165 L360.25 B175 H505[/c], can be the cause for autocalibration causes a headcrash?

If i send a [c]AUTOCALIBRATION[/c]…. they should not stop the movement of Nozzle, when ZStop was on? When head reach bed, whatever the order M665

Yes because in the M558 line you have H10 this tells the firmware to run down to the bed (H550 in your M665) to 10 mm short at high speed then slow down to probe for the last 10mm because you have the starting hight set to 45mm longer than you Z Actually is it tries to travel to 35mm below the bed before it starts to probe.

The other thing you could do is to increase the H Value in the M558 to say 60 and try it but do remember that once the Calibration has finished and you put the correct figures into your Config.g (And you should do this) then you will have to reduce that M558 H back down to 10 or even 5.

Hope this helps

I have a dude…

i do this:

1- Power on Duet printer
2- Homing
3- Test Z-Probe (Mini IR Sensor). Seems work, in DWI, Zprobe=538
...
and the problems
...
4- Test autocalibrate
5- The nozzle goes down slow
, in the way i put an obstable in Mini Ir Sensor, the same works, zprobe=558... but movement dont stops
6- Power off printer for avoid headcrash

why dont stops to go down?
G30 S-1... works, object stops go down nozzle

Bed compensation.... WORKS!!!!!!!

Why "cojones" [c]autocalibration[/c] fail??????????????????????

peirof

Hi,

Bed compensation works…. but strange results...

When you makes a [c]calibration[/c], Duet do the[c] bed.g[/c] contents, no?

my bed.g, for if someone can see the fail….

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors
; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed)

Another strange thing, is when i do a single [c]G30 S-1[/c], works. But when i try to [c]calibrate.g[/c], a series of G30 gcodes….DON'T WORK...

dc42

1. In your M558 command, aset a high H value for now (e.g. H40) until you have calibration working.

2. If that doesn't help, what happens if you send the first G30 lin from your bed.g file, i.e. G30 P0 X0 Y154.58 H0 Z-99999 ?

3. Confirm that X0 Y154.58 is reachable by the IR sensor, and not off the edge of the bed or closer than 10mm to the edge.

More info…

i have try, to do 1 line of [c]bed.g[/c], by console.

I have sended [c]G30 P0 X0 Y154.58 H0 Z-99999[/c], and…

The first thing, this command by console don't works.

In this moment, i have sended [c]G30 X0 Y154.58 H0 Z-99999[/c], without P0 and… partially works, the nozzle goes down, until Zprobe trigger, and stop the movement, until this point works, but the nozzle dont go to [c]X0 Y154.58[/c], the test is meassured WHERE THE NOZZLE WAS…. i dont know if this behavoir is normal...

NOTE: i have read the message of DC42, after post...

1- In this moments, i have this [c]M558 P1 Z1 H40 F120 T4800[/c], think this change yesterday, i haved read in forum

2- This is what I just tried and commented on the previous post

3- In teory, yes. The bed has 310 mm of diameter/2= 155 mm, in the limit, i go to down this measure
