ASUS ROG Fan Grill – Monoprice Ultimate (Wanhao D6) – Timelapse and Printing Tips

Here is a timelapse print recorded by OctoPrint running on a Raspi connected to my Monoprice Ultimate 3D printer (basically a Wanhao Duplicator 6).  I’m printing the additional components for the ASUS ROG HERO MAXIMUS IX & X motherboard’s for myself and a friend.  After recently updating the printer with the latest 3.2.1 firmware mod,  soldering the X/Y switch relay bypass wire, and adding custom start/stop GCODE, this thing is really dialed in and printing perfectly.  Read more to see details on the new Gcode!

This GCODE seems to be the best custom code that I have found so far.  I was having issues using the stock GCODE as it wasn’t extruding enough filament before the print to prime the print head and while printing the raft layer it was clogging up the nozzle.  This extrudes quite a bit (yes, uses more filament) but then proceeds to lay down a much better raft layer and adheres to the print bed much better.

I found this code on a post on the Thingiverse forums here:

He also posted his Cura settings, which I tried and they work great for a better raft layer as well:


I also found this page dedicated to Wanhao D6/Monoprice Ultimate mods and tips which has some of the best and most complete information in one place on upgrading this printer that I have found anywhere:

I have already added the Borosilicate glass plate on my print bed, and after relocating the limit switch and adjusting the limit screw, it works great.  Much better than the stock print bed material that it came with.

Since I mostly print with PLA, I haven’t added a new hot end or enclosure yet, but I might at some point.  However since I’ve got PLA printing so well and I have a bunch of filament stocked up, I doubt I’ll switch anytime soon.

Finally, check out the prints I’ve done for our motherboards.  The files are provided by ASUS on the ROG motherboard page here:

And here is the outcome:
