Thank you both for your efforts and time, i DID find my mistake after all. You know, sometimes my brain is so crippled that i cannot see clearly. Somehow i added the same offsets to Tool 0 script. All is good now..

@gloomyandy
No problem,
well
g31
Z probe 0: current reading 0, threshold 500, trigger height 5.000, offsets X57.0 Y-4.2

all is fine, but still its not taking it into effect with g32

@fcwilt said in Homing and bed levelling dont employ Bltouch xy offset RFF3.3:

G30 P# Xaaa Ybbb Z-99999

I have chosen points that the probe is physically able to reach. Doing a single g30 with coordinates doesnt consider the offsets, unfortunately.
Any more ideas? What else could be wrong besides syntax errors in my config.g or bed.g?

@gloomyandy said in Homing and bed levelling dont employ Bltouch xy offset RFF3.3:

this is the result i get from your suggestions

Hello,
I am trying to setup a 400x400 blv with triple z axis, and for the love of God cannot understand why when homing and running G32, my probe offset doesnt come into play. Instead, the nozzle is going to the specified locations instead of the probe. Can someone please take a look at my relative files and tell me where i have screwed up. Thanks in advance for all help.

Hello, I have this little issue.
I have set the homez.g and homeall.g files, for the head to probe the center of the bed for z homing (x250, y250).
It never does, it just goes to x250 y0 and probes there.
Can you please check and let me know what I have done wrong? That also affects the bed compensation i think, its never correct.

I have the files here for your consideration, thank you for all the help.

Hello David, sorry for the late reply. The V1.03 is actually fine, it was the effector that somehow failed, i switched with a new one and all is fine. Only trouble i have with this one (or any for that matter), is that i cannot successfully set up the resurrect function...

On the V1.04 now, i dont see any burned chips, but I cant be sure. I tried everything in the wiki but no luck. I guess i should send it back to you for checking and repairing it..

Hello to all. I have technical trouble with 2 duet wifi boards and i would appreciate any help.

One of the duets is v1.04 and has been working fine for about 200 hours on a corexy in my shop, 24v psu fed by a UPS , but 2 days ago i run into a serious issue. I switched the power on, hit auto calibration but because my zprobe was disconnected, i switched it off before the nozzle crashed the bed. Turned it back on and the ui on the lcd was stuck on "connecting", no readings on temps, no gcode files showing in card, endstops not signaling on the motherboard etc. I removed the micro sd, which seems like its fried as the pc doesnt read it either, still lcd has no readouts on tems and console is not returning any communication to gcode commands. All Endstop leds are dimm but connected endstops do work and go fully bright when activated. I cannot see or smell anything burned. 3,3v 5v , usb and wifi leds are steady on when i plug usb from laptop, but i get no port connection. i tried switching usbs on laptop and cable is fine as i connected my other duet machine on it, no problem (well there is an issue on my other duetwifi but will get back to it later on). So basically i cannot connect it anywhere..
I prepared a new micro sd with the proper root structure and latest firmware from dc42s github, send gcode to install it, no respose from console and no luck.
Whats your guess?

Same day and a few hours earlier and after a 22hour print on my big delta with smart effector, i run into another issue. This is a v1.03 board i purchased from reprapworld last May i think, and has been working fine for a while now..also fed from 24v psu on UPS
Before i started the last print, i run auto-leveling without any issues. When i tried to reconnect my pc via wifi after the print, it would not (not unusual after or during long prints that i turn on and off my pc a couple of times)
Usually switching off and on the printer solves the connectivity issue in such cases, as it did this time.
The problem is that now the z-probe circuit on the board has somehow failed. The green led on the effector works normally when the nozzle touches sth, but the probe value is always 1000 regardless. checked the wiring for continuity, the effector for shorts, no problem there. but i think i did find a short between the 3.3v and Zprobe Mod pins on the board itself.....
Any ideas on that? Printer works fine other than that....

Thanks and looking forward to your support..

Hello and thanks in advance for any help knowledgeable people around here can offer..
I have a DuetWifi big Delta running on 24v 250w psu, powered by a 450W BRAND NEW UPS, no heatbed, nema17 motors, smart effector and volcano with 0.6 nozzle.

I have 2 serious problems (as I am mostly running over 10h prints on it)

The first is that i constantly get pauses on my prints with "Resume-after-power-fail state saved" messages on the console, which basically ruin my prints (large lithophanes and every time i resume i get a lovely horizontal line on the print that you can see from miles away) . The strange thing is i get them even though i dont have any other signs of power surges in the building (lights dimming or trembling). Maybe its a bad UPS, i cannot rule that out, but i dont know how to check this. I also have a 60watt dc cob led with a step up regulator on it for lighting the printer, running from the same psu. I have tried with and without it turned on, makes no difference.

The second very important problem is that i really dont understand how to setup and use the resurrect function.
here is my config file

I tried having both sd cards on the set (not sure if the paneldue one was needed for this but have one in the slot anyway).

Can somebody please explain step by step what i need to do to resume print after a powerfail? Am I supposed to find a sys/resurrect-prologue.g file on either sd card and print it? (there never is such a file after a powerfail). Or should i use the M916 command somehow?(tried but keep getting that there is "no sys/resurrect-prologue.g found" message

Please help..
