Hi, first I want to say I really really appreciate this video. I bought a Wanhao D6 used for $20. They sold it because they couldn't get it to level correctly and the nozzle kept banging into the build plate , but in their efforts to repair it they had completely disassembled the gantry and didn't know that it needed alignment so they made a half hearted effort to put it back together. When I first tried to set it up the head was binding in certain areas on the gantry and I was trying to figure out if the belts were too tight or something else was wrong and after stumbling across your video I realized that they didn't align it correctly when they put it back together. However, I do have one question for you on the 8mm rods I have two that are longer than the others but the video doesn't give any specifics on where they go I'm guessing it should be easy to figure out but I thought I'd ask before I tried putting this thing back together. Thanks much and keep up the good work.
@@othermod do you have experience with bend 8 / 6 mm rods, non centric ball bearings and a bend z ball screw? I think my printer has them all :) I've already replaced some bearings, but after my latest intervention I'm stuck with a bonded X/Y gantry which made me buy a Prusa mini as a 2nd printer. After seeing your video I have my hopes up I'll get this one printing better then ever before. These imperfections mostly show up as z banding and sporadic imperfect extrusions, not too bad actually if you see the state of the ball screw or some rods....
@@tijntje2be Yea I've seen all of those issues too, except for the 6mm rods. All my 6mm rods are fairly straight. This video and the one I'm releasing in a few days should help with the frozen x/y issue. As for the banding, you can try completely removing the upper retainer on the z screw. Sometimes it constrains the axis too much, and the top retainer doesn't really add much stability because everything else is so solid. I'm a bit obsessed with this printer, and I'll continue releasing videos showing ways to improve it. Its a really awesome printer once you fix the quality issues.
@@othermod with upper z axis retainer you mean the aluminum block at the top of the z axis, holding the bearing? So just let it float? Regarding the 8mm rods, any benefit to replace them with straight ones? or does the construction provide enough stiffness to overcome the non-straightness? I have looked at replacement parts, but as all the Chinese parts, the replacements are not necessary better....
@@tijntje2be Yes, exactly. It can just float and the large rods and bearings will keep everything aligned. As for bent rods, yes I recommend replacing them. The Chinese ones are hit or miss on straightness. Try finding an Ultimaker part reseller and get rods for the UM2. If you're in the US, FBRC8 is a good place
Awesome mods - I recently grabbed one of these printers and am in the process of refurbishing it. Any tips on fw, slicer and profiles, other mods to use are appreciated. Any way we can make a one-time donation? I'd like to spiff you for the existing and future monoprice maker tips.
@@othermod Thank you - you are saving me a lot of time on the learning curve to get this printer printing. All my other printers are Marlin-based bed slingers. I want to enclose it to be able to print higher temp materials like nylon - the used one I bought has a mosquito hot end installed. If it works I will buy a second one.
@@othermod I just don't like the Idea of giving out my phone number, home address and e-mail for something if it is not going to cost me anything for the files. I I just can't wrap my head around why you need all my personal information. Until now; I get it you are only interested in the sales. I thank you for the offer I have a couple of printers or so as my wife says LOL. I could print them. I was just going to get the files. :)
I'm just poking at you for complaining about something that's free. I needed one place for people to download the file or buy the printed one, and WooCommerce just makes everyone use the same checkout. You can put fake info in the site if you want.

Great information! Looking out for the follow up video showing the assembly!
Thanks. Should have the next video out sometime next week.

I have a video from last year, and I talk about the profiles at the end ruclips.net/video/orAiletNKN0/видео.html
also, I have a donation link in the video description (Linktree). My response keeps getting removed by RUclips when I reply with the link included.
@@othermod Found it! Donation sent with my thanks!
@@reasonablebeing5392 thank you sir for the generosity

My abillities with 3D printers are horrible...
Why do you need my phone number, home address, e-mail and all the other information for the free STL files?
I can make them not free if you prefer.
