Are the OUT_3, OUT_4, OUT_5 PWM connectors on the 6XD only PWM controllable or also analog voltage controllable? To connect and control 3-wire fan? And if yes, How?

accelerometer combined with pt100 thermocouple on 6xd
Hi,
The documentation about combining the pt100 and the accelerometer is a bit confusing for me.
The documentation states: If your Duet mainboard supports more than one temperature daughterboard (Duet 3 6XD), and you have one temperature daughterboards installed, you can connect the accelerometer to the top of the temperature daughterboard.
Do they mean that I install the pt100 board as standard and then connect the accelerometer on the same SPI connector on top of the connections of the pt100? A schematic would clarify a lot here. I would not even mind drawing it, if I knew which points to connect with which one. I want to keep the accelerometer constantly connected. -
RE: Paneldue7i with 6xd and long cable with sd
@Phaedrux
If i understand it right: 1.5m is not a problem with the 4-wire cable with molex connector, but without sd functionality. Sd functionality is only possible with a length of max 40cm
?
With my former duet 0.85 i had regularly some problems with network connectivity, so i am used to troubleshoot directly via the SD. But habits can be changed -
Paneldue7i with 6xd and long cable with sd
Hi,
I was reading through the documentation of the paneldue7 and couldn't find a straightforward answer on my question.
I want to connect an Paneldue7i (version 2.02) with an 6xd (v 1.1) with a long connection cable of 1.5 m. I would still like to use the SD card reader because my 6xd is mounted on top of my printer (2.6m high) and not really accesible. I will do most interactions with the webinterface but would still like the possibility to work via the Paneldue7i if not to difficult.
The flatcable (10 wires) is clearly not an option because more then 40cm. What are my options and how do i have to connect them? If the 6xd is similar to one of the version of the 6hc, it would be handy if somebody adapt the documentation to clarify.Edit: In the specific wiring page for the paneldue the 6xd is also mentioned , so documentation is in order, my reading skills .....

RE: controlling (multiple) closed loop steppers
@fcwilt Thanks, that answers all my questions. I will indeed go that route: the 6XD for all servos and closed loop steppers. and if i have a normal stepper i can always choose to use the 3HC addon or the tool card or an extra external driver. Solved.

@dc42 Thanks,
Then i will go for the braked version of the servos.How do i put this question as solved?

RE: How to enable and disable brake on 6xd?
@lazy_mosquito Would it for instance be possible to use the enable pin or the 5V_ext from every driver and connect it to a relay to trigger the 24V needed for the brake? Or is there a better way? How would i create the delay for putting on the brakes?

How to enable and disable brake on 6xd?
Hi,
I have a delta XL printer and i am redesigning it to be used as a ceramic printer. The extruder of the ceramic printer is much heavier (between 1 and 2 kg) So everytime i cut of the power the head falls down. I will now install integrated servos with a brake. How should i wire the brakes on a 6XD?

RE: controlling (multiple) closed loop steppers
@fcwilt Thanks, this solves my problem for the normal steppers and the servos, but not the use of encoders. At this moment i found only the 1HCL capable of using a stepper with encoder, or is there also a way to get this functionality with one of the other boards?

RE: controlling (multiple) closed loop steppers
@fcwilt Problem: I have a delta build which will use the 6XD and 3 servos for the arms and i need at least 1 normal stepper and 1 to 2 steppers with an encoder connected to my extruder, and as far as i can see in the documentation the 6XD doesn't support normal steppers and only the 1HCL supports the encoding signal. I would prefer to have one expansion card which supports multiple standard and encoded steppers instead of 1 tool board 1LC and 2 1HCL boards. thats why i was wondering if the 3HC board could deliver this

controlling (multiple) closed loop steppers
Hi,
Is it possible to control closed loop steppers with the 6HC, 6XD or the 3HC expansion board, or is this only possible with the 1HCL expansion board?

RE: Is the 3HC expansion board also compatible with 6XD
@jay_s_uk Thanks for the swift reply. On the following page in the connectivity part it states only the 6HC and the mini 5+:

Is the 3HC expansion board also compatible with 6XD
I would like to connect 3 easy integrated servos to a 6XD board for a big delta. But i also need to control 2 to 3 steppers on the extruder. Can i connect a 3HC board to the 6XD. The documentation says its only compatible with 6HC and the duet mini 5+

RE: 6XD with isv or isv2 "servo" for ceramic delta xl
Looks like i am not getting a lot of response.
Questions not clear or nobody used integrated servo motors before with 6xd? -
6XD with isv or isv2 "servo" for ceramic delta xl
Hi.
I have a big delta build which i want to transform to a ceramic delta printer. The build volume is 600mm diameter by 1000mm height. The construction is sturdy enough for the upgrade but the steppers are not. I have no exact numbers of the extruder yet but i expect the weight of the extruder to be something between 1 and 2 kg and it is connected to a press with a rather stiff/flexible tube. The printing speed will be lower than filament printing but still the inertia of such a heavy extrude will need some sturdy steppers or servos.
I found the isv serie from stepperonline (https://www.omc-stepperonline.com/nema-23-integrated-easy-servo-motor-180w-3000rpm-0-6nm-84-98oz-in-20-50vdc-servo-motor-short-shaft-isv57t-180s) and wanted to combine them with this gearbox of 3:1 (https://vi.aliexpress.com/item/1005002775269715.html?gatewayAdapt=glo2vnm) Because the isv series gets speeds to 3000 rpm with a constant torque output it would mean that with the gearbox i could have a constant torque of 1.5Nm with a speed of 1000 rpm.my questions:
-
Is there somewhere a way to calculate how fast my delta will move at the outer diameter (600mm diameter / arms are around 600mm long and i would use a gt2 9mm kevlar belt with 20 tooth pulley)?
-
Would this be strong enough for moving this head?
-
anybody has any experience with this isv serie combined with 6xd duet 3?
-
i expect that most of the special features of the 6HC board are driver related so are not usable in the 6xd or are they software implemented?
thanks in advance

RE: How to home (G28) midprint and resume?
@lazy_mosquito
Can you add a bracket to the printer frame (bed respectively) were you park&lock the effector before filament change?Thats an option i was also thinking about, but more complex to achieve compared to code.

RE: How to home (G28) midprint and resume?
@phaedrux
Thanks already for your answer.
I would expect it behaves similarly to adding it directly in the code.But I will first try to invoke it via the pause and the resume macro and sees if it makes a difference instead of invoking it directly in the g-code.
i just create the macro's and invoke them manually after the prints pauses?

RE: How to home (G28) midprint and resume?
@phaedrux
This would work in a normal situation, it works on my Prusa. But on the Prusa it is very easy to change the filament without moving the printhead, which is almost impossible with my delta printer.
The problem is, that the printer will restore its position from the existing,moved, coordinates, but when the head is moved by replacing the filament, the printer has lost its absolute position and will go back to the wrong position, that's why I would like to home it first. In that way, I can reposition the head back in a known position and start from there.
My printer has rods of 72 cm, which makes that any force you put on the arms easily overpowers the holding force of the steppermotors, specially with my extruder. It works very well but is a pain to load new filament.
