I have a Mooz3 that has never been able to print anything, ever. In this discussion, I want to have Dobot tech support walk me through troubleshooting. They initially wanted me to email support. I thought having the discussion here may help others with similar issues and allow others to engage in the conversation as well.
The discussion began here, where I hijacked another thread. Now I want to continue it here. Here is a recap of the conversation. I sent this:
I did manage to get the unit to move by re-applying the firmware with a different SD card. I still could not get the touch screen to work even though I was able to get that firmware updated as well. It would also not connect with Octoprint. I could get the unit to move but not print. It just burned a couple of holes in the print bed and made plastic spaghetti.
There is a major flaw in this unit and it could just be a weak heating element but the nozzle will never reach the correct temp to print with the fan on. When I disconnected the fan, it was able to reach the correct printing temp but now I have a high probability of melting the filament all the way up to the bowden tube.
If you are willing to assist, I might re-assemble the parts that are now in a box. Before I start, I have a few questions.
- Have you seen the nozzle heating problem before and found a solution?
- Have you seen the touch screen problem before and found a solution?
- Will you share the firmware source?
- Are there plans to update to Marlin 2.0.x?
I received the following response:
I’m very sorry about that because everyone always discusses technology and shares experience in the forum, Dobot does not carry out after-sales service of products in the forum, so your question has not been quickly answered by DOBOT official. If the product is damaged or cannot be used at all, this is already part of the after-sales content, so it is very necessary to contact email@example.com.
Comprehensive analysis of the problems you encounter. I think your touch screen is damaged (this is currently a malfunction on the hardware), please contact firstname.lastname@example.org to complete after-sales content. In addition, while the nozzle is heating, the fan has been running. I used my mooz3 to test that it can reach the printing temperature. This may be a firmware error. What’s your MOOZ3 firmware version, please show me a picture like this.
If they insist on email for support, I will post the conversation here for the reasons I mentioned above.
