I will try changing my start and end settings
Thanks Fixxer

I read your article on Bed leveling of Monoprice Ultimate 2.
I have had my Ultimate 2 now for about a year and printed a lot of stuff on it, with mostly good results. When I got my Ult2 I did not understand how the bed leveling worked and assumed that being new my bed was level. Printed stuff and everything OK. Then I had problems with things not sticking to bed, so I adjusted Z offset Problem solved. I noticed my Prox. Censer was loose. With z offset set I moved censer up and down till the red light just came on. Don’t know if this is the proper way to set but it worked.
I am at the point now that I think I may have to level the bed. I noticed that Filament bead is thick on one side and thin on other. With The V2 setting being the closes, my nozzle is still aprox 2.5 mm away from bed. Don’t know if I have that much adjustment with leveling screws.
Would appreciate any comment from you.
This sounds like your sensor need to be adjusted in height. No clue what printer you are talking about, but usually the problems are the same.
I would tighten the bed screws all in and then loosen them a little (1.5 turns each). Now make sure the z offset in your printer is set and saved to 0,home the printer and check the distance. Lower the sensor until it senses the bed. Usually there is an LED. With a switch you hear it click. If it is a BL-Touch you need to lower it, until it touches the bed when the arm is deployed.
Since you had the bed screws all the way in, there should now be enough room to lift the bed to level it properly. Depending on the firmware configuration you may also be able to “overdrive” the z switch zero position in software. But this depends on the used firmware and its config, as e.g. you don´t want to go lower when having a physical switch, but you may have some additional space with a BLTouch, an optical switch or a proximity sensor. In most cases this is not enabled by default as you may crash into your end stop and damage the printer, which companies what to prevent in the first place.
@old_guy81 I also had trouble with the Ultimate 2 bed leveling so I created a users guy to help everyone out. Check it out at:
Finally leveled bed on my MU2 thanks to Dr Vax Video. It was off so far I’m amazed I was able to print as well as I did for so long with a bed that far out of being unlevel.
I am a Fusion 360 user and a former SolidWorks designer. I am conserned about my free license on F360 they keep restricting what u can do. I have to keep tract of what I keep on the there cloud. and there is a notice every time I use the program about how much time I have left on My yearly license. Last year they renewed with no Problem. Now I have 15 days left
So I started to use FreeCAD, but it is hard to break old habits and the program keeps crashing on me. It does not seem too Stable.Or maby its me!!!
Dr Vax mentioned something about, Him using version 19 insted of 18.xxx that I downloaded. Ver19 was Experimental that was why I downloaed 18.xxx.
Any Comments Dr VAX ?
I’m not DrVAX; I don’t even play him on TV ( 
), but I would go with v19. It is really close to being released.
I’m still using F360. The current free license does everything I need. I still keep an eye on FCAD, hoping its issues will get resolved.
Thanks for the info Ender5r
I will try ver19.
Do u use FreeCAD?
I gave it about a month-long shot maybe 6 to 8 months back, and I’ve visited it again every month or so since. So far, F360 wins out.
FreeCAD 0.19 should be released any day now. 0.20 will finally officially contain the topology naming fix, which finally makes FreeCAD usually to fully extend without the need of avoiding such situations from user side.
0.20 will feel like a complete new application for sure.
I also started with Fusion360.
And its a powerful and nice userfriendly Software. My licence is still ongoing.
I know that the licence will not stay forever so i decided to look in an other program. I tried also freecad, i was not able to get in the software.
Now i using DesignSpark Mechanical and i like it!!!
Please take a look in this program. You have to register with an e-mail Account but its free to use, there is no limit. You can enable module yes but for my work is enough.
If you try it and export your document to an .stl file first go to the Options–>File Options STL Resolution. Here you can setup how your resolution for an .stl file should be. I noticed this later after some prints and one print was not really round enough.

@flixxer, I’m having a little trouble understanding the difference between DSM & F360. They seem to have basically the same concept: offer a free version in order to promote their paid version. Why wouldn’t the free version of DSM not get more restrictive, just like F360? Still, I thank you for making us all aware of its existance. I had never heard of it.
@Geit, thanks for the info on FCAD 0.20. If they really fix the topology naming issue, that will be huge. If they also address some of the more clunky aspects of FCAD, that would be a major bonus.
Nothing for me. First paying with my data and in the end I need to start over with yet another application.
All these “free to use” applications will bite one day anyway, so I prefer using really free stuff. On IRC many people already hit the limits of the F360 private thing. They are private, but their projects are a little bigger than usual. And since the .step file format is just a transfer format, you loose stuff in the process.
I´d rather deal with some hurdles which will be removed over time, then with hurdles that will be added over time.

Yeah, hopefully all python issues are gone. Many applications are currently on hold, because of Python2 -> Python3 update. They had five years to perform the translation and now in January 2021, when Python2 was finally and officially without support all developers start struggling to get the applications and even more problematic their plugins to python3.
They don´t want to release the main application as it would look like a step back with all the missing stuff, so they wait. It took Kodi about 6 month to get an update this year. Within this period of transition nothing got updated. Some branches like the RaspberryPi “LibreElec” still did still did not get an update and is already two weeks behind.
To get back to 3D printing. Even OctoPi still comes with the unsupported Python2, for the same reason. Plugins are not ready for P3 and they did want to do a full translation. They just use the unsupported version, which will cause more and more trouble, the more time goes by and the more security issues appear.
Everyone screamed at using “Flash” and its security risks. Right now Python2 is at an even worst point. A language that defines applications and their usefulness drags a pile of crap behind and the user pays the price in non working plugins or not updated software.
Using a language that it not static, but changing its commands and behaviour with every new version is just shit.
Dependencies are a mayor problem these days and since all people jump to python, this got even worth.
@Geit, is FCAD 0.20 available for download anywhere, or are they not at that point yet?
F360 is so close to what I’ve used in the past and has other features that are great once u get used to them. ie top down modeling, surfacing sculpting etc. I hate to loose that. and FreeCAD is clunky at best. but it does the job for 3D printing if u can keep it from crashing.
It is now. Just the 0.19 with the functionality, but it is out of date compared to the pre release version. At least the last time I checked.
Crashing got reduced a lot with the recent 0.19 beta versions. Also when using Windows it almost never crashes, due to the exception handler, which is missing on Linux. I am using FreeCAD since 0.15 and it got far far better over the years. Just keep in mind that just a hand full of people working on it in their spare time, while big companies pay big developer teams to work on stuff every day to proceed their applications.
Recent Fusion360 changes triggered a huge fallout. Many people jumped onto the FreeCAD train, which gave it a big boost, too.
Thanks for info Geit,
I am just about to load ver 0.19
I purchased the MMU2 after watching Dr Vax’s review, and several others on youtube. I’ve had a great experience with it. I had a nozzle that clogged so bad I couldn’t clear it printing PETG, but the nozzle assembly is easy to get to, easy to replace. I picked up an extra extruder module so I have one on hand, and swapped out the original with the new one. I did have to follow Dr Vax’s leveling guide, and after purchasing a 5.5 mm deep well socket, that only took about 10 minutes. trying to use the 5.5 mm spanner they send with the printer would have resulted in me returning it to amazon.
Overall, I’ve had the printer for about 6 weeks, and except for the 2 days I was waiting on the hot end, it’s been running almost non-stop and printing great.
First would like to say big thanks to DrVax for your wonderful work and videos around 3D printing, it was pleasure to get first touch to the printing from you on YT. Got my first 3D printer around week ago and decided to go for monoprice ultimate 2. Couple of test prints from SD card, everything looked very nice and headed for my first own project which came out pretty nice with white PLA included with the printer. Slight problem I noticed that this cylinder type print was not completely smooth, it had some 30+ “corners” which basically could not felt by hand but against light they were visible. Headed to the next print from same file but slightly modified as I messed up some measurements and then the problems started. Print was not sticking to the tape and I replaced them all and still the same issue occurred. Searched the info and found your very nice bed leveling instructions and proceed accordingly with the same software version as you have. Leveling went without troubles (including Z offset which was like -0.3mm), did crosscheck that now at least three times and all seems to be fine. Well, now after this, printer is starting the prints almost 1 cm above the plate and result is obvious. No matter what I do or what file I use, the issue remains the same. I don’t know nor understand if this comes out from printer settings or is this somehow related to CURA (4.8.0). On CURA all the settings are like with yours based on screenshots and like mentioned, the previous project worked fine with CURA slicing.
Any good tips before I contact monoprice support? Thanks in advance and again thanks for your all efforts on community and newbies like me.
I would try changing the Z Offset more, mostly to see if it makes a difference. I would try -7.0 mm to start. Make certain you have your finger on the power switch when it starts to print, so you can do an emergency power off. This is really a test to see if the printer can start closer to the bed.
Hi Ender5r, many thanks for the comment/suggestion. Is there a way to adjust this without having the nozzle movement physically throughout calibration process as I cannot set it more than -0,3mm as the bed comes in a way. 1 cm mentioned earlier is actually -5.8mm now that I had a change to measure it more precisely. On the DrVax instructions I selected V1 and then adjusted the bed based on this. I don’t know if I actually should go for V2 but I do afraid that I’m going to get hit on the bed during process. And why would it not work with V1 as again, everything is seems to be level and calibrated but it just starts now 5.8mm above the plate…
