Its a development printer, until it ready would like to leave any pics, specs etc in house.

@Phaedrux said in How to assign another Fan to Fan0.:

M563 P0 D0 H1 F3

its Jumpered to Vin.

@Phaedrux

Yes i checked fuse. The always on Fans are working

Yes RFF2

M106 S255 has no effect.

P.S. on Marlin i can remap the pin, can i do something similar on duet.

The other option is change the board, but i should not have to do that.

This what i had originally
; Fans
M106 P0 S0.3 I0 F500 H-1
M106 P1 S1 I0 F500 H1 T45

; Tools
M563 P0 D0 H1 ; Define tool 0

It all was working Fine
Now my Fan0, FAn1, Fan2 do not work.

tried running gcodes below

M106 P3 S255
M106 P0 S255
M106 P1 S255
M106 P2 S255

Fan 0 Fan1 Fan 2 do not turn on

But Fan3 does.

So I chance my config to this

; Fans
;M106 P0 S0.3 I0 F500 H-1
M106 P1 S1 I0 F500 H1 T45
M106 P3 C"Part Coolong" S0.3 I0 F500 H-1

; Tools
M563 P0 D0 H1 F3
G10 P0 X0 Y0 Z0
G10 P0 R0 S0

So if i send M106 P0 S255
Fan 3 does not turn on, as all my gcode files have that.

So my original question is how to Remap Fan0 to another Fan within duet Config, not the slicer.

And yes i would say my duet board has gone faulty, but i should be able to remap fans.

That would be great.

Ok granted for Bowdens.

But i am using a bondtech QR extruder and at 2mm is to fast and the the stepper is skipping

Using a Duet with 2.85mm filament, i find the extrude speed of 2mm per sec to fast.

Any chance of making the speeds pre-settable?

speeds of 50mm, 20mm are useless for most extruder setups.

Thanks in advance.

Is it possible to set a display password on panelDue.

Basically to leave printer un-attended and stop people from playing with controls.

Thanks for that.

I wanted to get away from the user trying to jog.

Your process will work, how ever having experienced a wide variety of customers and their abilities,
i would like a one touch solution

That was the reason of using a plate to make electrical contact with the nozzle.

What one user assumes is touching the plate, another user will think there should be some pressure against nozzle, so it opens it up to a variety of settings.

Since hardware like the BLtouch has come out, it has made 3d printers a lot more user friendly,
how ever the process of Z-Offset is one of my greatest customer support issues.

We produce a lot of custom made larger format printers, so bed levelling becomes a critical process as opposed to common 200x200mm and smaller build plates.

We have recently switched over to Duet/Reprap controllers, so slowly getting familiar with it.

I would like to implement a feature that will calculate my nozzle to bltouch offset.

The idea i am thinking of is i can have a metal plate mounted next to bed or clip on bed.

This can be wired to a switch input that is normally open.

home Z till nozzle touches plate, this giving me a Z=0

Then use BLtouch to home on that metal plate.

Then all i need is the difference in mm between the 2 Z homes.

And that is my Z Offset.

I am trying to make the 3d printer as simple as possible to operate

I am building a Large Printer with 3 Independent Z motors and axis.

Besides the Normal Bed Leveling on this which cam be done.

What i would firstly like to do is Physically get the bed as level as possible before running a bed mesh levelling.

Ie, be able to probe near each axis and move each motor to get the bed physically level as possible.

Then run normal mesh levelling.

Thanks in advance.

I am trying to figure out how to report the z bed error amount in mm to the Console only.

Ie If i do a Z home, then my Z is set to 0.

I would like to know if its possible i can manually run a code to prob a position giving co-ordinates X,Y and report only on Console the difference in mm.

do not reset Z, just show me the result either in console or pop up windows from webserver or on PanelDue display, or both..

Thanks in advance.

Solved.

Was due to Maximum speed and acceleration of extruder not set high enough.

Idea is you can get a partially full spool and put it in, and would have a rough idea how many meters are left.

I can make a sensor and lever setup,

just need some one to do the software and build it into the firmware.

I was thinking a very useful feature is a sensor that will report how much filament is remaining on the spool.

How i would propose this to be done, is have a lever setup that rests against filament on roll, other end to a potentiometer.

That is wired to say Thermistor 7.

You could then have set filament spool settings, Like diameter of empty spool and full spool, width of spool and diameter of filament.

also then run a spool calibration which measure resistance of pot when spool is empty and spool is full.

With that information you should be able to calculate how many meters of filament left.
Doing it by weight wont work due to the variety of filaments.

by knowing that and comparing the estimated gcode filament need, you can quickly see if you have enough filament left.

What you all think?

@dc42
i am currently using the duet ethernet for evaluation for one of our clients for a number of printers.

also noticed if i scan the ip using a net scanner, it does not return the name of the printer.

but this does work on the wifi unit.

But on Wifi units this works correctly.

This would really be handy, especially if you are running multiple printers.

Wow, fast response and at least you may look at it if other want it.

I have converted from smoothieware, have not looked back.

Keep up the good work.

Since we know the Heater element Power and Heater bed power in Watts.
whilst the printer is printing, the heater is controlled by pwm.

Is is possible to show average Wattage per heater every 5-10 seconds on printer status screen.

thanks

so in config you enter each heaters wattage.
Say for 800Watt bed
whilst it print if duty cycle is about 50% over 10 sec would show 400W
