@dc42 I just tried it.
This did not make a difference for me.
The firmware was correctly installed and the name displayed on the Paneldue corresponds to the one you provided.

@T3P3Tony Thanks a lot ! I missed them when I read through the object model I don't know why.

@gloomyandy @infiniteloop @jay_s_uk
I believe you were right and the problem was indeed a wiring problem.
With the printer on, I just jiggled the connector on the duet and the readings went off the charts. I believe it's just bad crimps and I will re-do these and it should fix the problem. I checked the cable themselves and they look fine.

However, this still does not explain why the heater fault was not triggered at 8:46 with the huge temperature drop.

@infiniteloop Yes I made a typo, I typed "M570 H4" (which is my bed heater).
Since I haven't changed this in my config.g, it's the default value for all the heaters.

And this is my config.g :

For anyone reading this, I spent 4 hours searching through RS and Farnell for references.

I removed all the cable with impedance not being 120 Ohms, and searched for 22-24 Awg cables.

The one I find that suit the best this application are the following :
(If some of the specialists here could confirm these choice that would be great.)

Alpha wire 6413, 2x(2x24AWG), Impedance 120 Ohms, Outer Diameter 7.1mm, Temp -20 to 80, unshielded :
https://fr.farnell.com/alpha-wire/6413-sl005/cable-24awg-2-pair-slate-30-5m/dp/1746265?st=6413

Lapp Kabel 2170204T, 2x(2x24AWG), Impedance 100-120 Ohms, Outer Diameter 7.1mm, Temp -5 to 70, shielded (i think)
https://fr.farnell.com/lapp-kabel/2170204t/cable-profibus-par-metre/dp/3034318

And if you want way overkill, you can run two of these cable

CFBUS.LB.021, 2x20AWG, Impedance 120 Ohms, Outer Diameter 8.0mm, Temp -50 to 70, shielded
https://fr.rs-online.com/web/p/cables-de-controle/1854913

The last one is the only one that is purposely made for dragchains and to move.

I will try my luck with the first one.

@dc42
Your solution worked.
However there is a behavior I don't really like.
When the printer is off both bed and chamber are off.

When the printer is on and duet is running, both chamber and bed are controled by the duet and can be on and off depending on temperatures and control values.

The problem is while turning on the machine (while config.g loading) or when I restart the machine using the emergency stop button, the machine is turning on both the bed and the chamber heater.
For me this is a problem as if the duet where to fail (bad SD or something else) while powered, both heaters would turn on uncontrolled...

Any way for the default state to be low ?

@Shoki I have another solution since I had to install a 3HC, it's just to connect the motor directly to the 3HC board...
The motor is this one, and it's rated for 3A so I can use a current of 75% of this rated current so around 2200 : M906 Z2200
https://cpdxkcnc.com/products/stepper-motor-nema23-76mm-30a-2nm-57hs76-3004a08-d21-05-569

But I'm still interested in the solution to the TB6600 since I could use a free motor slot on my 3HC, and I don't want to have to buy a 1HCL or a second 3HC for it...

@droftarts Hi

Thank you very much for your reply.
I had time this week to test your solutions.

For X and Y, everything is working perfect. I realised the connector on the motor sides could be disassembled so it in the end it was quite easy to modify it there.

Regarding the Z motor driven by the TB6600, I tried your solution and it does not seem to work.

• I checked my wiring multiple times and everything seems like on your diagram.
• I checked the value of my resistor, they are 10k.
• I tried to change the M569 R parameter, no difference.
• I checked what I was getting on the EN/DIR/CLK at the TB6600 terminal : almost everything seems fine, signal goes from low to high on EN when I turn motor on (with the correct M569 R parameter), and signal switches on DIR when I switch the direction command. Only problem is : signal is not at 5V but at 1.4V which is probably my problem... I also checked what I was getting on the other side of the resistors and I did have 5V as expected.
• I tried to connect the X motor to this driver (to check if wasn't a config problem), and once I switched the M569 R parameter, X was working (when moving in Z), which is what I expected.

Any guess on why are my signals too low with this wiring ?
5V lane from the 6XD is not strong enough to pull the signal higher ?

Hey everyone.

I'm working on converting a new printer to a Duet.
The printer is a Creatbot D600 Pro that uses two different kinds of stepper driver for Z and for X/Y.

I already did the conversion once, but I previously used a 6HC (which was stupid) with three 1XD. And now I moved to a 6XD board but i'm having problems with making the motor moves.

This is the input for the Z stepper driver which is a TB6600 :

And this is the input for the X and Y stepper driver which are this reference. Note that the connections from factory are made with common grounds (to PUL-, DIR- and EN-) and the signal are passed to the PUL+ DIR+ and EN+.

I managed to make it work with my previous machine and the 1XD boards with connections like these :

External stepper for Z TB6600 -> 1XD Board
CLK -> D0_STEP (+)
DIR -> D0_DIR (+)
EN -> D0_EN (-)
GND - > GND (on the IO0)

External stepper for X and Y -> 1XD Board
PUL+ -> D0_STEP (+)
DIR+ -> D0_DIR (+)
EN+ -> D0_EN (-)
PUL-, DIR- and EN- > GND (on the IO0)

Now I moved to a 6XD board and there are no longer the DIR+ and STEP+ pins on the 6XD board. So I did this :

External stepper for Z TB6600 -> 6XD Board
CLK -> D0_STEP (-)
DIR -> D0_DIR (-)
EN -> D0_EN (-)
GND - > GND

External stepper for X and Y -> 6XD Board
PUL+ -> D0_STEP (-)
DIR+ -> D0_DIR (-)
EN+ -> D0_EN (-)
PUL-, DIR- and EN- > GND (on the IO0)

It does not work. Nothing moves. I understand the problem that I have is that I only have low signals (-) and no 5V in my wiring, but I don't know how to do it differently...

I checked with a multimeter and the EN signal (from EN- to 5V) and DIR signal (from DIR- to 5V) are working as expected (going from 0 to 5V, when I turn motor on or when I switch direction in the moves). So I don't think it's a firmware issue.

I have a few question :

• There is a bridge that can be set in the firmware, is it the same as changing the R parameter in the M569 command ?
  

• In the 6XD documentation here, there is this sentence :
  "To connect a Pololu/StepStick/similar driver to the 6XD a 10K pullup resistor is needed from the Step/Dir/En lines to +5V"
  This might be what I need to do, but I don't understand what a "pullup resistor" is and how I should connect them.
  I also found this sentence :
  "The Step and Dir outputs from the 6XD are either low (when "on") or floating/high-impedance when "off""
  From my understanding, it's related to above so the step and dir outputs are at GND when low (on) and are just "whatever" when off ? And the "pullup resistor" would make the "whatever" be 5V when off ? Did I understood that correctly ?

• For the X and Y motors which have all poles (DIR+/DIR-, STEP+/STEP-, EN+/EN-), I see on the same 6XD documentation that it's recommended to have the common 5V to the DIR+ STEP+ and EN+. It's different from the wiring that I have from factory and I'd rather keep them that way if possible as the motor are very hard to access and would recquire a lot of disassembly to modify this wiring... Is it possible to make it work with a 6XD without changing these cables ? Maybe with the same pull up resistor trick ?

Thanks in advance for your help.

@chrishamm the mainboard is installed with 3.5.0-rc.1. Same as the Duet Web Control.
I don't see a line with 1XD (not the same as on my other printer, where there is one)

Nothing is connected to the 1XD for now. Only power and CAN.

Hi,

I'm facing a problem with a new 1XD.
I can't seem to make it work.
I replaced it in my system with a 3HC and it worked flawlessly, no problem with CAN communication.
I replaced it with an old 1XD I took from an other printer and it's working no problem (but I need the old printer so i had to put it back !)

I tried to fit a jumper to reset the board, as recommended in the documentation. It did not change anything.

The thing that worries me the most is the fact that the status led is always off.
The 5V red led and the blue VIN led are both turned on.

It's a 1XD V1.1

Is this a sign of dead board ? How can I diagnose/solve the problem ?

Thanks in advance.

@dc42 Thank you very much this will work !

Hey

I'm trying to adapt a semi-industrial printer to a duet board.

There are two electronic cards on the printer for now :

• One is a regular marlin printer
• The other is handling all the power (bed, chamber, 220V input, emergency stop, etc).

I would like to replace the first one with a Duet and keep the second one so I don't have to redo all the mains wiring, order some relays etc...

There is only a 5 pin cables between the two cards. And it's the only part i'm unsure about the transition to Duet.

The pins are labeled like this :
B -> Bed -> which goes from 0 to 3.3V when bed is turned on
C -> PTC -> which goes from 0 to 3.3V when chamber is turned on
G -> GND which for me is just the ground (and i used it to measure the other)
V -> 5V which is just 5V
P -> ACCK I have no idea what this one is/does and it's just always at 3.3V

Here are my questions :

1 - Any idea what ACCK means ?
2 - The original board seems to be switching the 3.3V and not the ground since there is only one ground for both the bed and the chamber conrol. From my understanding of Duet boards, it's switching the GND and not the 3.3V (Vin).
Any idea how I can wire this secondary board on a duet to make the two heaters (bed and chamber) work ?

Thanks in advance for the help.

@edsped I have added an on/off switch on my PanelDue so I turn it off when I don't use it. Hardware solution to a software problem.

Found the answer to my own question, should have searched the forum first.

@dc42 said in EndStop Accuracy Test:

@Nazar in RRF 3.5.x the machine position is read during moves instead of only at the end of a move, and at most every 250ms. So if you read the machine position immediately after the G1 H4 or G38.2 move has completed, you may gat a value that is up to 250ms out of date.

I suggest you insert command G4 P260 after the G1 or G38.2 command, before you read the machine position.

This solved the repetability problem with the G38.2 command.

I also found this post :

@dc42 said in EndStop Accuracy Test:

@Nazar I think G1 H4 will do exactly what you need.

Will the G1 H4 command work for my application of XYZ probing too ?
In the gcode dictionary fo the documentation, i found this on G1 H4 :

G1 Xnnn Ynnn Znnn H4 Sense endstops while moving, update the current position at which the endstop switch triggers (supported in RRF 3.2-b4 or newer).

But which endstop does it sense while moving ? All of them ? I did not find a parameter to tell him which probe it needs to monitor ?
