DreamMaker 3D 3.3.6

The stylish and smart 3D printer evolved to be the most reliable and user friendly choice!

#6212
I'm opening another discussion on this issue. Since firmware made public last year, I have lost the ability to connect my OctoPrint server to the OLP! I've asked numerous times for help from the makers but it must have been deemed non-essential to them. I ask again, Dream Maker, please look at fixing your firmware or at least make it public again so someone can fix our problem.

It seems lately no matter whether I have a USB cable plugged into the printer and attempting to connect to it, OR I have it sitting alone and power it on... I keep observing that the LCD display keeps recycling the OVERLORD banner. When I select OK then the recycling stops and the Print screen is displayed. Although this is annoying, it does not prevent me from printing locally off of the SD card. So the issue is within the firmware somewhere at the start of Configuration.h.

I'm pasting what I was able to capture from the OctoPrint server's terminal window if any of this helps. See below.

AGAIN I ASK FOR DREAM MAKER TO FIX THIS PROBLEM.

Thank you.

UPDATE: I downloaded the https://github.com/jimaobian/MarlinForOverlord files and corrected the baud rate to 115200 and that fixed the problem with the recycling issue. However, I am still unable to successfully connect with OctoPrint or from LULZBOT's version of Cura. I tried the REPRAP Marlin/Sprinter options so I could access the printer control panel, and I was successful in connecting and saw the SD Card but that was as far as I could go. I had no XYZ controls and I was unable to send over a print job.

With OctoPrint I continue to receive a communication time out even wen BAUD RATE was manually set to 115200.
This is what OctoPrint passes back. Note the last few lines.

I had the same issue and went back to a lesser firmware on the Overlord.

Just got the hotend upgrade and will need to update the firmware for that, so my 3d printing experience is about to get a whole lot more shitty.
#41495
Just had it confirmed by Octoprint devs that the serial connection of the 2.3.5 firmware is completely broken.

We need a new firmware or to downgrade.
Sadly, with the new hotend (finally working) I am unable to downgrade and so will have to resort to sd card printing.
