[not yet solved] Tevo Little Monster DuetWifi errors
-
This error is given at any time the trigger is released during the calibration:
Error: Z probe already triggered at start of probing move -
Try increasing your dive height.
-
The M280 PS3 and M280 PS7 commands in your slicer starts script are not right.
I suggest you home the printer and then test the bltouch as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

Thanks for the support!!!
I'll try all you suggestions
I changed the starting script with this, as in the guide conversion is suggested:
G1 X0 Y0 Z100 ; lift nozzle to 100mm
The ending script:
G28 ; home all axes
M106 S0 ; turn off cooling fan
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
M84 ; disable motorsNow what I have noticed is , when I power on on the printer it star the calibration but of several point that it is suppose to touch just the first near 4 points use the trigger, that is released twice! Then the trigger stay released and the printer continue to move to all the other points.
Im almost sure is just a question of settings.
I read in other post that the new releases of firmware work slightly different and some Gcode have to be removed. Im trying to figure it out.
Thanks again for your time!My bed.g:

; 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)

Edit:
Chronology with success for the calibration:
If I run the G30 as suggested in the guide for the dynamic single probe the console return:
G30
Error: Z probe already triggered at start of probing move
The light of the BLTouch is blinking.
The trigger is released.
And if I try to send M280 P3 S90 I1 (also without i1) nothing happen.
Sending M280 P3 S160 I1 (clear the BLT errors) the trigger retract and the light stop blinking .
Now the G30 work and slooooowly the head go to the bed with the trigger released and stop retracting the the trigger and turning on the light when it touch the bed.
Ok, the head stop some mm before the bed so I sent M208 S1 Z-3 for make the nozzle touch the bed.
I sent the G30 S-1 that report:
Stopped at height 2.440 mm (I putted a pad near 1mm thick for avoid impact with the glass)
Now in the config.g i wrote something like this:
G31 X0 Y20 Z2.440 P25 ; Set Z probe trigger value, offset and trigger height.Well...after rebooting the printer calibration was different. The points checked was far more than before. For all points the trigger was released 2 times. The calibration end with the head on one side of the bed.

Do you mean what i have done or something else?
Of course I beg your pardon for my incompetence. -

Fine , seems you were right for make a complete calibration to work.

Keep trying to solve all the issues:
1)Now, After calibration the head stay on one side close to the bed.
If i send a G28 for home all axis just the Z turn to home , the other 2 move just a little .
G28 Error: G0/G1: insufficient axes homed
In the WCC >>>Machine control>>> the home x and Home y are orange and I have to home twice for making finally home the other two axis.
I have seen this : https://forum.duet3d.com/topic/4782/error-after-upgrade-to-1-21/2
but i cant understand if this is the right direction to investigate..
2)When I restart the printer the wifi give an error in the console of the touchscreen :
Error : M587: Failed to add SSID to remembered list HTTP is enabled on port 80 FTP is disabled TELNETBUT after the calibration the wifi start to work properly.
Is not a big deal, is just for understand... -
Unfortunately I cant print a thing.
All the file printed stay on printing continuously on the 1st layer.
The gear of the extruder consume the filament in the same place because the filament cant be extruded.
It seems that the printer is unable to rise on the Z axis during the print
The extruder seems to work properly. I can extrude and retract the filament. But when I print the head stay on the first layer0_1537552075875_Tevo_LM_Duet_Adapter_v1.gcode -
I know you've gone through a few guides but it kind of sounds like your motors aren't responding as expected.
Can you take a look at this delta setup guide and compare it to what you have?
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter
-
Sure! I'll check your link and I will report here...
Is my first printer and is all new. I'm glad to learn new stuffs .
Could be as you suppose. All the guides are made for different motors from the original ones.
I changed just this:
M92 X80 Y80 Z80 E425 ; Set steps per mm , that were settled on x160 y160 z160 for the 0.9 motors. -
Phaedrux ,
I have read all the document you have linked. And for what i can see the data should be coherent.
The section where with the G91 command (for allow to move independent axis) to check if the motor work properly , is executed without errors. The motors seems work all fine.
If i move down the x axis G1 S2 X-10 it go down and vice-versa if I move up the x with G1 S2 X10 it go up. the other two axis go fine.I don't know if is a Slicer problem. Im using Simplify3D with settings i used with the original Tevo . I just changed the firmware section for add the RepRap configuration be loaded.
Then....
in the homedelta.g there is this line:
; Move all towers to the high end stopping at the endstops (first pass)
G1 X505 Y505 Z505 F1800 S1
and in the config.g there is this one:
M665 R155 L397.19 B155 H525 ; Set delta radius, diagonal rod length, printable radius and homed height
The 505 above should be far height than that?
In the kossel example with an height of 240mm volume the G1 command is settled on 320. If my printer have an height of volume of 525 how much i should add to 505?; homedelta.g

Nothing to do , also Cura (last version) produce the same thing.
The printer dont rise during printing on the Z axis. Stay on the same level all the time and the gear of the extruder consume the filament in same place blocking further extrusions.Suggestions?
tnx

It's just odd that the motors will move properly when commanded manually but not when printing. Can you verify the motor current while printing? Send M906 and then M913 without parameters in the console and it will report what the current is set to along with any percentage scaling. Maybe there is a rogue current reduction command happening somewhere.
-
M906
Motor current (mA) - X:1800, Y:1800, Z:1800, E:1800:1800:1800:1800:1800:1800:1800:1800:1800, idle factor 30%
M913
Motor current % of normal - X:100, Y:100, Z:100, E
100100100100:100I tried different voltages for the 4 motors. Are all identical and the default should be 1.8.
I tried also 1200 and 1000. Nothing change.
I tried also the firmware 2.0 but didnt work either. Exactly same attitude as the 2.01.
The probe is settled well ,it perform a good calibration without errors reporting the graph of the surface. Of course not rising the z axis during the print generate a mess of plastic under the extruder.Im starting to feel a little sad...
There is something that can inhibit the Z axis rising during the printing?

@giostark can you post the code file you are trying to print
-
0_1537811866488_stab.gcode
0_1537812126970_Tevo_LM_Duet_Adapter_v1.gcode
Maybe those files and setting are not perfect but the first (stab) with the original motherboard was printed several time.
Im able to perform a "good" calibration without errors. For this reason I dont think is something related to the hardware. I settled the zprobe and the first layer is printed well. the second one come printed on the 1st and so on generating a mess of plastic.

This post is deleted! -
Well I notice 2 things from your gcode file. First, you don't have a G28 in there to home the printer, so if it isnt already homed when you start the print it may cause problems. Second, your Z moves are all negative.
