Thanks for that.

Hi,
I would like to echo the value of 'heat.heaters[1].current' in the following line of code as an integer (i.e. no decimal places). Currently it always displays it with to two decimal places.

echo "Heating the nozzle to " ^ global.filamentTemp ^ ", it's currently " ^ heat.heaters[1].current ^ "°C"

It must be easy but I'm feeling a bit thick today!

@jay_s_uk Hi, I've not uploaded files here before so I hope I'm doing it right!
config.g
homex.g
homey.g
homez.g
homeall.g
Whilst you are looking at these I also can't get the PanelDue to display.
Any Ideas?

Hi, I had been getting on fine with sensorless homing with my duet3mini5 board. Both the X & Y axis were homing almost silently and ultra-repeatable with just one contact needed to work.
However, I was getting an error message with the X-axis, it came up as...
"Error: Pin name needed for switch type end stop on X-axis ". I don't understand this homex.g is identical to home.y (except X's and Y's! of course). Why is it asking for a pin name when it's sensorless ?

@chrishamm thanks I tried that but the printout does not show all the details in the original web page. I could not find the PDF option anywhere. Where is it?

Hi, I have asked this before but didn't really get a reply.
Is it possible to split long lines of code, typically M291 lines over 2 (or more) lines of code?
These lines can easily stretch to 150 columns or more. When comparing files in 2 side by side windows it can make reading the code difficult.
I would like to be able to split these lines at some point so they are physically spread over 2 (or more) lines in my text editor ( I use sublime).

@chrishamm I was actually looking to be able to have a hard copy (printout)

Hi, Just a quick one.
Is it possible to get a full printout of the results from the Reprap configuration tool?
If I click on the open file and select print I only get parts of it printed. I really want a good print with all the alterations I've made.
I presume this because its a webpage not a text file as such.
Is this possible?

@Phaedrux , thanks for that.

Hi, I have a few 5V LED blades designed to fit into USB ports that I think are fabulous.
I would like to use one to illuminate the nozzle and surrounding area on my printer.
I am using a Duet 3 mini 5+ running with a 24 V supply.
How could I connect this, ideally being able to control it with gcode?
Any ideas would be very welcome, especially with with some coding suggestions.

@handyandy Hi, I have just spotted the solution to this at the end of the 'Getting Started' document. I should RTFM more!

Hi, I replacing my Duet2 WIFI board with a Duet 3 mini 5+ board. Previously my Panel Due 7 connected with a 4 wire connection. I don't want to use the ribbon cable method. I can't see anywhere on the new board for this to work Can anyone help please?

Hi, I am working through a new build printer and have another problem.
Using my Duet 2 WIFI board I have Fan0 connected as the print cooling fan and Fan1 as the extruder fan as you would expect with the following lines in my config.g file.

M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8
; 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
M307 H1 R4.153 K0.495:0.000 D3.20 E1.35 S1.00 B0 V24.3 ; Results from act PID tuning
M143 H1 S290 ; Set temperature limit for heater 1°C to 290°C
;
Fans.....
M950 F0 C"fan0" Q500 ; Create fan 0 on pin fan0 and set its frequency
M106 P0 S0 H-1 ; Set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 ; Create fan 1 on pin fan1 and set its frequency
M106 P1 S1 H1 T45 ; Set fan 1 value. Thermostatic control is turned on at 45°C
;
Tools.....
M563 P0 S"Extruder" D0 H1 F0 ; Define tool 0 (extruder)
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0°C

The problem is that whenever I turn the printer on fan1 is on full speed and will not turn off.

I Have a spare fan and have tried it in all 3 fan positions. In fan0 and fan3 it works perfectly. The speed can be altered as required or switch off by sending the M106 commands directly to the dashboard. In fan1 the fan will only run at full speed and can not be turned off. This is a simple test but seems to pinpoint a now faulty board.

None of this happened before the rebuild as is always the case!!

I think it was during PID tuning that something happened? I completed the bed fine, but the nozzle seemed to be working as expected until nearly over then the red graph line suddenly became extremely erratic with wild fluctuations in the stated temperatures as well. I also briefly saw a warning for (I think) an open circuit.

Do you think a heater/thermistor fault in the Hemera Revo extruder has fried one of the mosfets on the Duet?

The only solution I can see at the moment is to replace the board (with what?) and the Revo heater/thermistor block?

@droftarts
Hi, reducing the feed rates for the Z axis looks to be the solution. Anything below F1200 seems to work well. Thanks for your help.
Just one more question... you mention setting M204 P2000.0 T2000.0 in config.g
Are your values for P & T rather high? If M204 is there to limit the maximum accelerations shouldn't the values be equal or only slightly greater the the values in M201?

@droftarts
Hi I think you may be right with Z being to fast. I have run Z from F500 insteps up to F1300 with the noises or uneven movement. Above that it's bad. So I was going to alter the config.g file M203 to limit Z to between 1000.00 to 1250.00 - what do you think?
Here is the config.g as it was with M203 Z2400.00!!!!

Hi, As well as the different leadscrew movement in the homing routines I also get...
In general Z axis movements (=/- 25mm) I get a 'squeal' from the Z motors with no movement then the uneven movement of 5-8mm. If I command 5mm or under it does not 'squeal' but at 5mm you see the uneven movement. Small commander moves of 1mm seem to work ok!
I hope you can help, it's driving me crazy!
