Is the PanelDue display my only option?

GeorgeM

I just came across this thread and since I had an old Bigtree TFT-24 lying around I thought I would give it a try.
I connected the 4 pin connector to the PanelDue connector and updated the firmware on the TFT. It comes up with all the icons but says no printer is connected. Do I have to connect more than the 4 pin connector?

@GeorgeM What firmware version are you using on the duet?

You may need to add a M575 command as listed by Jay above.

@GeorgeM You 100% need an M575 in the config and you need to set the baud on the BTT panel to 57600

@Phaedrux I would suggest going with

M575 P1 S3 B57600

You also need to be running RRF 3

GeorgeM

I should have been more specific.
I'm running 3.1.1
I do have the M575 P1 S3 B57600 in my config file
I have a duet2 wifi

@GeorgeM on the btt tft you need to match the 57600 baud rate as well...if not wont work!

I'm not sure how to do that. I just followed the directions linked above at github and copied the files to the sdcard. I assumed that since the directions said to have the M575 line in the config then the bin file contained info to set the baud rate.
Anyway its no big deal if I dont get it working. Just thought I would give it a try.

Is there a menu on the panel itself?

jay_s_uk

yes, in settings

GeorgeM

OK, found that. Didn't help.
If I have only the 4 pin connector connected, then I can see and operate all the icons but says printer not connected. If I then connect the 10 pin connector the screen comes up with the option for Marlin or TFT, however it will not accept any input -- will not go off that screen.
Again, I don't want you guys to spend a lot of time on this as it isn't a make or break problem. I would like to know if it is something simple I am overlooking.

jay_s_uk

@GeorgeM can you confirm that the rx and tx pins are swapped?
The RX on the duet should go to the TX on the screen and vice versa

GeorgeM

Thanks @jay_s_uk . That was it. I had just plugged in the cable as it was without tracing the lines. Working now.

While I'm glad to hear that you found the problem, you're lucky it wasn't the power wires which were not hooked up as expected. That would have been a much more painful way to learn the lesson.

When it comes to cables, even directly from the manufacturer, always double check them with a multimeter and against the documentation as to what should go where or Murphy will hunt you down and make you pay!

Case in point; I unwrapped a brand new receiver to put in an RC model I was building the other day. I was about to use the programming cable which was included but I reminded myself of the "Check the cable" rule. Wouldn't you know it? Power and ground were reversed. On a cable from the manufacturer which was in a sealed anti-static bag together with the receiver.

Mistakes will happen and if you don't work on the basis that all cables are incorrectly wired until the opposite is proven, then sooner or later, you'll be letting the magic smoke out of something. Inevitably, this will happen when you're in a hurry and replacement electronics are only available from the other side of the planet.

Hi everybody

I am just installing Duet 2 Wifi in Creality Ender 5 Plus, and I wonder if I can use original 4,3'' touchscreen?
It has similar specs to older/smallest Paneldue, and is really nicely mounted in the chassis. And upgrading to 5'' or 7'' Paneldue it means additional enclosure.

I don't want to just plug-in-and-wait-what-happens-next, don't want to fry anything.

Here is the specification of this display:

I will greatly appreciate if sb. can check if it looks safe and possible.

edit of the above - the actual display model is DMT48270C043 _06WT, similar but newer, I suppose.

How is the display connected to the orginal Ender 5 MB?

treetopped

four wires - 5V, GND, Rx2, Tx2 (there are additional Rx4 and Tx4, not used)
there are no other connections (I assume SD card port is not functional)
