Hello Forum,
I am new to owning my own 3D printer but have been using them for a number of years now. I bought a Sovol SV03 and have had it for 2 weeks. It is for my business, making custom part and patterns for casting. I use my own CNC Milling machine and CNC Router on a daily basis. That said this is a new field with lots to learn. I find the Sovol machine a B- . I bought it because it has a large build area and I was hoping I could use it to make large patterns and core patterns at a less expensive cost than other means. Right now with the high failure rate of parts, 50% and long print times I am not sure.
Some things I have learned are that once you get a PROFILE in Cura that works, do not mess with it. I am using PLA from Sovol so far and I have a profile that works. I have made a spread sheet that I would be glad to share with anyone who are interested. The first layers laid down are the most critical. I have found running a test pattern of a large 9" square that's only .25" wide and .25" tall is the best thing to do every day before making a part. Also you have to clean the build area with Isopropyl alcohol before starting.
So I am anxious to hear from other users of filament printers that will share their profiles for different materials. In the CNC milling field Speeds and Feeds are everything. There a many tables and spread sheets one can use and they are shared by other machinists. I would hope this would develop in the 3D printer field as well. Right now it seems like there is very little commercial guidance by the machine manufacturers or I just have not found it, yet.
Thanks,
CismontGuy

There are many different slicers and profiles for the almost unlimited amount of filament and 3D Printers. This is the reason most of us have joined a 3D Printer forum. As you have stated the 3D Printer machine Manufactures knowledge an sharing are very poor with the exceptions of a few that have Outstanding support. Cura is a Good slicer you may soon note that some of us here prefer prusaslicer, Being a free slicer it has many advantages of a professional slicer. The good news is your Sovol SV03 is using the same Marlin 2.x.x firmware that is being run on both my 3D Printers an my DIY MPCNC Router. I have upgraded my 3D Printers through many Marlin firmware that I have configured form Marlin 1.x.x - Marlin 2.0.7.2
Looking deeper into your 3D Printer it appears to be using a CrealityV2.2.1 Dual extruder controller which my controllers are the predecessor of.
This means that the Prusaslicer already have a default profile for you to start using with your Sovol SV03.

Welcome to the forum. Yes, there are many brands out there, some better than others, but they can all be made great printers with a little patience. And you are 100% correct. Once you find or tweak a profile to where it works, stick with it. Better yet, save the profile so that it can be reloaded on updated versions of your slicer or shared for others who may have issues with the same printer.
That Sovol looks like an Ender 3 but larger. If that is the case, your biggest challenge will be getting it dialed in with just the right profile and just the right settings, and just the right z offset. Once you get that sorted out, I think you'll truly enjoy it. Look forward to hearing more about it.

One week later using my Sovol SV03 3D printer and the honeymoon is over! I have been trying unsuccessfully for 2 whole days to print some parts I made 5 times, a week ago,! The problem is adhesion. I have experimented with print speed on 1st and 2nd layers, (down to 7mm/sec) the size of that layer (.15 to .2). Right now it looks like I cannot go any finer than .15 . Anything lower than that with the .3 nozzle and nothing happens. The nozzle just gets all gummed up! I have repeatedly cleaned the build bed with a clean cloth and alcohol, I have leveled the corners and used the self leveling system on the print head. Parts get started and then, Bamm! slide off! I have tried running my large 9" x 9" x .5" wide test print and it does fine. I have adjusted the speed of printing and the Z offset. Right now its higher up than it was a week ago? Not happy.

From what I can see you can adjust the nozzle closer to the print bed by changing the Z-Offset about 0.1mm should to it M851 Z-0.1 or add 0.1 to this line in marlin Firmware. #define Z_PROBE_OFFSET_FROM_EXTRUDER

I enabled
#define BABYSTEPPING This allows me to adjust the nozzle in baby steps while I print a skirt using the LCD Control. Keeping track of the number of baby steps allows me to use a thumb screw mounted Proximity sensor slide height to the correct level for other prints.

Try cleaning the build surface with dish soap and water. Dry thoroughly. This will degrease it from the oils from your hands. Then go back to ipa until you have adhesion problems again. And yes, you may have to level again if you changed anything, but I think the oils would be your original problem. I tend to use IPA most of the time, and the dish soap once or twice a month, depending how much I am printing.

I had a build surface had problems with it until I 3D Printed my first ABS Model then the PLA had perfect adhesion.
May it wants to be heated up good to kind of cure the surface this may make the filament stick better, worth a try.
