@gdefranc lcd della tronxy non va bene con la duet, quindi ho preso il paneldue 7i, a livello meccanico devo cambiare le chiocciole mettendo quelli in derlin "pom" e dovrei sostituire una t8 che e' storta, gia' da quando e' arrivata la stampante, poi vedro', ho intenzione anche di modificare l'asse z portando da 2 motori ad 1 con un kit di alluminio fatto da https://www.dmakers.it/componenti-per-stampanti-3d/kit-one-z-motor/ , ha solo un problema questo kit, che bisogna acquistare altri pezzi che non vende lui, ma comunque di facile reperibilita', per quanto riguarda il piano di stampa non sto usando il vetro ma uso il suo originale che non e' affatto male

Buongiorno,
vedendo che qui è scritto anche in italiano, mi unisco per condividere e leggere le mie ( poche) e vostre esperienze...
io sto per avviare una stampante fatta interamente da me, sulla falsa riga di sharebot.
asse z con chiocciola a ricircolo, asse y con doppio motore opposto e cinghia GT2, asse x motore singolo e cinghia GT2, carro estrusione a doppio estrusore, dove come principale uso un e3d V6 all metal, e some secondario un e3d v6 lite e bltouch per livellamento piano.
Elettronica con duet ethernet e duet panel i5, ammeniccoli vari come power supply, mosfet per piano riscaldato.
allo stato dei fatti non ho ancora mosso un motore....ho finito i cablaggi, ad esclusione del bltouch.
Prossima mossa sarebbe quella far muovere i motori.
vi faccio due domandine....
domanda 1)
sui due assi x e y ho messo due finecorsa...mentre il finecorsa high (diciamp Y+ e X+) immagino debbano finire come finecorsa di home, quelli sulla parte low (X- e Y- e Z-) vorrei metterli in serie come emergenza. qualcuno di voi ha inserito un emergenza di quel tipo? se si, come?
domanda 2)
per raffreddare gli stepper della scheda ho collegato due fans da 12 v ai pin always on della scheda.
avendo una alimentazione a 24V ho portato il 12v al pin centrale come da descrizione (togliedo il jumper che selezione i 5V interni. Le ventole non si muovono. devo verificare se effettivamente sui due pin il 12v arriva....ma ci sono altre verifiche da poter fare?

Intanto vi ringrazio per la pazienza nel leggere tutta questa "spataffiata" di roba!!!

Ciao

@logriso via google translate:

ask you two questions .... question 1)
on the two x and y axes I put two limit switches ... while the high limit switch (say Y + and X +) I guess they must end as home limit switches, those on the low part (X- and Y- and Z-) I would like to put them in series as an emergency. Did any of you put in an emergency like that? if yes, how?

You can home to the high or low endstops, but not both; RepRapFirmware only supports one endstop per motor/axis. There is not much point adding an 'emergency' endstop, because the maximum and minimum movement of the axis will be limited by the firmware. After homing, the endstops are effectively ignored.

You can do it if you really want to; connect the 'emergency' endstops in series, connect them to an available pin connector on the Duet, and use M581 https://duet3d.dozuki.com/Wiki/Gcode#Section_M581_Configure_external_trigger to configure this to pause the printer if triggered.

question 2)
to cool the board steppers I connected two 12v fans to the always on pins of the board.
having a 24V power supply I brought the 12v to the central pin as described (I remove the jumper that selects the internal 5V. The fans do not move. I have to check if the 12v actually arrives on the two pins .... but there are other checks what can you do?

There is no 12V regulator on the Duet, only VIN (24V) and 5V. So you need to use a buck regulator or something else to step down to 12V. See https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans#Section_Using_12V_fans_when_VIN_is_24V

@logriso Also, probably best if you start a new thread.

Buongiorno a tutti,
aprofitto della interessante discussione per chiedere informazioni su un problema che mi ostacola nel passaggio da RRF2 a RRF3.
Ho una LK4 pro con vari upgrade ( doppio asse Z con viti a ricircolo e assi X e Y con guide lineari e BL-touch v3.1) e monto una scheda Duet2 Wi.Fi.
Attualmente è tutto perfettamente funzionante e configurato, ma dopo aver portato il firmware alla versione 3.20 non riesco a configurare i fine corsa.
In realtà funzionano ma al contrario, attualmente hanno il contatto NA ma la scheda si aspetta un NC.
Dando il comando home si muove un attimo e si ferma, perchè legge che è già a fine corsa. Se invece faccio l'hon di un asse chiudendo manualmente il contatto, l'asse si muove correttamente e lasciandolo si ferma. Nel config.g ho questo riga:
; Endstops
M574 X1 S1 P"xstop"
M574 Y1 S1 P"ystop"
Ho provato a cambiare i paramteri con altre combinazioni ma i fine corsa restano sempre invertiti.
Con il RRF 2.05 funziona perfettamente.
Avete qualche suggerimento?

Grazie

Hello everyone, take advantage of the interesting discussion to ask for information on a problem that hinders me in the transition from RRF2 to RRF3. I have a LK4 pro with various upgrades (double Z axis with ball screws and X and Y axes with linear guides and BL-touch v3.1) and I mount a Duet2 Wi.Fi card. Currently everything is fully functional and configured, but after bringing the firmware to version 3.20 I cannot configure the limit switches. Actually they work but on the contrary, they currently have the NO contact but the board expects a NC. By giving the command home it moves for a moment and stops, because it reads that it is already at the end of its travel. If, on the other hand, I hone an axis by manually closing the contact, the axis moves correctly and when it is released, it stops. In config.g I have this line:; Endstops M574 X1 S1 P "xstop" M574 Y1 S1 P "ystop" I tried to change the parameters with other combinations but the limit switches are always inverted. With the RRF 2.05 it works perfectly. Do you have any suggestions? Thank you

You must invert the signal of the pin using a ! before the pin name

M574 Y1 S1 P"!ystop"

@Phaedrux

Thank you very much ! I try as soon as possible.

Gianluca

Sorry for my English...

Tried the modification to reverse the endstop “!”, it works perfectly!

Now, to make the printer fully functional with the new RRF 3.2, I have to configure the BLTouch ( problem 1) and make the heater of hotend pre active when switched ON my Duet2 (problem 2).

(PROBLEM 1) BL-Touch Not running good on this test settings
; Endstops
M574 X1 S1 P"!xstop" ;OK configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop" ;OK configure active-high endstop for low end on Y via pin ystop

; Z-Probe ( like https://forum.duet3d.com/topic/14907/bltouch-not-deploying-rrf-3-0/5 )
; M307 H3 A-1 C-1 D-1 ; Disable Heater 3 for use with BLTouch (UNNECESSARY)
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F300 T6000 ; set Z probe type to bltouch and the dive height +
G31 P500 X-7 Y-23 Z0.73 ; set Z probe trigger value, offset and trigger height
M557 X5:230 Y0:223 S100 ; define mesh grid 3x3 punti

(PROBLEM 2) At printer ON, when I increase the hotend temperature on PanelDue display, it does not heat up. I need to press the heater icon and turn it ON (red background), after that, does it start to heat up.
In the heatbed, this does not happen, as soon as I increase the temperature and type set, it starts heating immediately. ( red icon turn ON directly )

My setting on config.g:
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 A149.0 C639.9 D1.4 V24.2 B0 ;Valore inserito dopo taratura letto riscaldato
M140 H0 ; map heated bed to heater 0
M143 H0 S101 ; set temperature limit for heater 0 to 101C
M308 S1 P"e0temp" Y"thermistor" T100000 B4092 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S290 ; set temperature limit for heater 1 to 290C

What exactly isn't working?
The config looks ok assuming you are using heater3 as the servo pin and zprobe.in as the trigger signal.

What do you have in your deploy and retract macros?
What do you have in homeall?
Does M401 and M402 work to deploy and retract the pin?

This is normal. A tool needs to be selected before it can heat up. In single tool printers it's common to add T0 to the end of config.g to select the first tool at startup so that temp commands can be issued immediately.

Gianluca

Thanks for your help !
Problem 2: With “T0” to the end of config.g all work perfect.

Problem 1: I find the problem: now work all good !!!

; homeall.g
; called to home all axes
G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-235 Y-228 F3000 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X5 Y5 F6000 ; go back a few mm
G1 H1 X-235 Y-228 F240 ; move slowly to X and Y axis endstops once more (second pass)
THIS IS TE PROBLEM !!! G1 H1 Z-255 F240 ; an old command in RRF2
G90 ; absolute positioning
G1 X110 Y110 F3600 ; Posiziono la sonda al centro del piatto
G30 ; Sondo il piatto con il BLTouch
;END

Thanks again !
