Hi all,
I have a question regarding the "recovery mode" after a power outage.
I use a Meanwell RSP 500w 24v power supply to power my prusa printer. I followed the documentation to set up this feature in the firmware.
My problem is that when the actual power outage occurs, the z axis does not lift and the extruder does not retract.
It seems that I have not much "power reserve".
How could I do to overcame this? Using an ups, as suggested by others, does not seem to be a good choice since the Duet would not see the power failure anyway.

Thanks for your help

Thanks again. I will try.

I cannot preheat the board since I have not the right tools. But I can regulate the soldering iron temperature. What temperature do you suggest is good to do this task? 350 C maybe?

Thanks

Ok, I have a Hakko FX-888D that I never really used, I think this is the right time to do so
Thank you all for your help

I purchased it from an authorized Italian retailer (compassdhmprojects.it).
I bought it long ago so out of warranty now.
From picture you cannot see the problem because you have to “feel” it under your fingers.
The appearance is perfect, just this little “gap” when you try to move the green terminal.
As I told, It is due to excess torque in screwing the terminal multiple times, not to a fabrication defect, so entirely my fault.
Just wandering if I could run this way or do something.

Hi guys, I have a little concern about my duet wifi board.
I noticed that the power screw terminal is not steady but it moves a bit if I touch it.
I can feel the connectors on the pcb being a bit “loose”.
I think it is due to the many times I screw and unscrew it reworking on the wiring on my printer.
But my questions are:
Is that dangerous?
Should I replace those?
Or could I just use the soldering iron to “re-melt” the soldering joint?

Thank you for your help.

I am sorry, the endstops for the 2 arms are under the base of the robot, so I could see them first.

no, there are not endstops. I have to figure out by myself. But why is that important? I mean, I know the importance of the endstops, but why asking me in this early stage of the project? is there a particular/important reason that I missed?

Thanks

Hi everybody,
I liked so much the duet with my prusa prnter that I thought it would be a great controller also for my new project: a robot arm.
I am going to buy just the frame on aliexpress (see attached image). The mechanism is like the famous uArm or Dobot.
My question is: could I use the Duet in order to move the robot?Is there a firmware somewhere that you know I might use? Or you have some materials to start with?
Thanks for the reply.

hi everybody,
I am facing a connection issue. Basically, when I try to connect to my printer via Web browser (I tried all of them and on different devices: iphone, mac, windows etc) most of the time it does not connect to it, showing me the classical message (see attached image).
I don't understand why is that happening.
My question is: is there a particular thing to do in order to make the connection stable?

Thanks
Luca
