I had to play with the value of rod length of 4th axis in M665 (its a bit more than the tubes length) and offset value in M669 (its less than actual) so that the bowden tube stays how I want it.

Hope it helps.

I recently installed the 4th axis for the extruder on my delta printer.
DuetWifi with Firmware 2.05.1
See it in action (2min30):

@WillGIam
Take a look here: link
Maybe you can use some of the code.

On a delta there is no fix resolution in XY plane. If one arm is nearly horizontally, the carriage has to move many steps to move the printhead a tiny bit, and is the arm nearly vertically then the printhead moves a 'huge' amount if the carriage move a little bit up or down.

check your config-override.g

From Allegro there are A1120 to A1123. But at the time I bought them, the only source was AliExpress and only A1120. Rare to get.

@Vlad as mentioned in your other thread, your 3.3V hall sensor is a linear output type. A buffer circuit will not help. You need a circuit with an comparator and a pot to form a didgital output.

Hey, i was writing a ton of text and now had to delete it
Do as @dc42 suggested, should work.
The SS49E has an analog output and is in its raw form not suitable as endstop.

@dc42 said in Duet 085 and Fans:

Thanks. Please try the new 1.24RC2 release, which should behave exactly the same 1.24RC1+1.

Tested and its the same.

I also used this line:
M106 P3 S1 I1 F500 H1 T45:100 L0.6 A4
and PWM is working as expected.
Mapping with A3 (Pin 21) and A2 (E1 heater) works also.
A big thank you.

@bearer said in PanelDue goes wireless:

I considered using HC-06 modules to make a bluetooth serial bridge, could give you a better battery life than WiFi?

I think the backlight from the display will draw the most current, so the bridge part current is not relevant.
Go with it and report back. Would be nice to see another way.

Hi all,

I had the idea to get rid of the cable from Duet to PanelDue (in my case to my own DuetMonitor with a Teensy and 5" RA8875 display), so I can place the Monitor where I want and even take it with me to another room (within reasons).
I didnt want it to connect to my router and have read about the ESPNOW protocol. Its working on 2,4G frequency but is a (multi-)point to (multi-)point data transmission protocol without connection to a network.
So I did some setup on a breadboard, and got a functioning prototype.
Then I ordered some PCBs, soldered the components on and got this:



Its working!! and no cable.

The PCB is 3cm x 4cm. I went with a 18650 LiPo battery holder with charger, so no cable at all other then charging.
Using and charging at the same time is possible with this battery holder.
But you can go with this:

mount it at the case and feed the voltage to the PCB. Power it with a wall wart or powerbank. A good powerbank should last several hours. The PanelDue gets the voltage through a short cable.
The PCB on the printer should be mounted where it can receive and send proper.

Because a panel of 4x4 PCBs was only a little more charge with p&p, now I have roughly 30 PCBs that I dont need.
This is a great community, so if you want you can get them for €0,75 each + €1,50 postage to Europe and US (up to 50g), €3,70 above 50g (from Germany).
The ESP8266 has to be programmed with Arduino IDE with ESP8266 Addon over serial. You can get the source code via email.

Technical Data:
You can choose between 8 IDs (Each pair has to have its own ID).
You can choose between 4 WLAN channels (1,4,7,11).
Set A or B for the ID. (There is no dedicated Master or Slave, each pair has one A and one B on the same ID and channel, and it doesnt matter which is on PanelDue and Duet side).
The serial port can be set to 19200, 38400, 57600 or 115200. Typically set to 57600 for Duet.
Its possible to use one PanelDue for different printers, but not at the same time: Change to another ID (and/or channel) on PanelDue side, press reset and you are connected to the other printer.

If you are unable to solder and program the PCB I can do this, but I dont have the components laying around, so I have to order them.
But it will then be €7 per PCB and I dont make a profit on it (I have no intention to make a profit).
So if someone is interested PM me.

And here is the schematic:

You have no tool selected.

Type in 'T0'
and try again.

Duet 0.85 is sitting on the test bench with termistor on bed input and a resistor on E0 input so the reading is 83.7 degC.

M106 P2 and P3 are possible, but the mapping with A parameter is all over the place. So i tried to find out whats going on with P1.

Measures are at fan header F0 and F1, heater header on 50pin connector H3 (pin 18), H4 (pin 21), H5 (pin 22) and E1 heater with oscilloscope.

After reboot:

• F0 PWM ok and you can adjust it,
• F1 PWM ok and you can adjust it, BUT same signal(inverted) on H3, this is wrong
• H4, H5 low

M106 P1 I-1 (disable F1):

• F1 low
• H3 low

M106 P1 A2 S0.5:

• E1 heater PWM ok
• H3, H4, H5 low

M106 P1 I-1:

• E1 heater off, ok

M106 P1 A3 S0.5:

• PWM on E1 heater (wrong)
• H3, H4, H5 low

M106 P1 I-1:

• E1 heater off

M106 P1 A4 S0.5:

• PWM on F1 and H3(inverted to F1) (wrong)
• H4, H5 low

M106 P1 I-1:

• F1 low (LED lit), H3 high
• H4, H5 low

M106 P1 A5 S0.5:

• F0 !! PWM is set to 0.5 (very wrong)
• you can set F0 with P0 AND P1
• H3 high, H4, H5 low

M106 P1 I-1:

• F0 low (LED lit), no pwm on F0
• M106 P0 S0.2 brings PWM back on

if I now use P2 I get the same behavior.
I hope you can solve it.

I think it is not possible at the moment, but will be possible with the introduction of conditional execution of gcode in some of the next firmware releases.

@b3n said in Duet 2 Wifi Delta Printer Wiring:

Front of the printer, with a tower on the front left and a tower on the front right and one center in the back.
Can it be x,y,z counterclockwise, or clockwise or what have you?

X -> front left
Y -> front right
Z -> center back

If you do so, the X/Y (cartesian)plane is right. X0 Y0 in the center of the bed. +X to the right and +Y to the back. If you wire another way, you get rotation of the plane or mirrored prints.

Put the following at the end of your bed.g:

G91
G1 Z-5
G90
G1 X0 Y0

and check the result.

Check for any M591 commands in your config.g
Post your config.g
After the print aborted type M591 D0 in the console and show the report.

@b3n said in Duet 2 Wifi Delta Printer Wiring:

when moving x or Y, on carriage moves while the others stay stationary. that seems reverse from the way ive seen them move.

A move on delta moves always all three towers together. The M665 parameter sets the duet in delta mode.

If in delta mode you can move the motors individually with G1 S1/S2

Using the S1 or S2 parameter on a delta printer causes the XYZ parameters to refer to the individual tower motor positions instead of the head position, and to enable endstop detection as well if the parameter is S1

This is used for homing.

@dc42 said in M116: optional +->°C or +-<°C threshold definition for H P & C?:

I just checked the code. The M116 S parameter sets the tolerance, default 2 degC.

I added it to the wiki. Please check.
