Big Tree Tech E3 RRF 32-bit board, sensorless homing to maximize print volume - SOVOL SV01, Ender 3

- เผยแพร่เมื่อ 15 พ.ค. 2021
- Today, I will install a new motherboard from Big Tree Tech, The E3 RRF V1.1. RRF stands for RapRep Firmware. This board can run both Marlin and RapRep firmware. It’s using an ARM Cortex-M4 168Mhz processor, which is much faster than the one used for many other 32-bit boards, a Cortex-M3 72Mhz processor.
The price of this RRF motherboard is pretty reasonable. It’s $38 on Big Tree Tech's official website. It costs a few more dollars if you buy it from Amazon, but you get faster shipping if you’re a prime member. This board has 4 TMC2209 drivers and is built in Wifi Module. I also purchased an IDEX expansion board which has another 2 TMC2209 chips to control the dual extruders or any stepper motor: it cost $10.
My original plan was to install it on the Ender-3 Pro, but I decided to install it on the Sovol SV01 instead. This is because the glass bed of the SV01 is 255x300, but the actual print volume is 240x280. Because the location of the X limit switch is right here, it’s actually limiting the travel of the X Axis. This area of the glass bed is unreachable. If we use the TMC2209 sensorless homing features, we can remove the limit switch and gain some extra print volume as the print head could reach from edge to edge of the glass bed.
If you follow my video, you can also install it on an Ender 3, Ender 3 Pro or Ender 3 V2. It would actually be even easier since you don’t need to compile firmware and you can use them directly from Big Tree Tech.

I am scratching my head. How did you acquire all this knowledge? Where did you learn to present it so clearly and precisely? You must have done a lot of research in your previous life.? Love your channel and love your presentation. Another Aurora/Helios 10-10
Just have to say you're so clear and concise with instructions its a huge help. There are very obviously other knowledgeable creators on youtube, however sifting through their stuff to find the information needed is so time consuming and unclear.
In fact, I have an ender 3 and the rrf board and loading the BTT precompiled firmware, my ender would not z home with the BL touch. However compiling my own firmware off your instruction (leaving out the sovol stuff of course) I now have working ABL. Thank you.
Very well done! You are amazing! Your instructions are perfect. I was able to get the sensorless homing to work thanks to your most excellent tutorial. You are definitely a great TH-cam instructor. Thanks again for all the hard work in putting together this video.
I love watching talented young women doing tech better than most men. Great job!! My board will be here today, I will use your video as a guide!
Just got this board for my SV01, thanks to your recommendation. I'll be installing it this week with your video. Can't wait to try it out. Thanks!
I have 4 printers, and until now, I never knew what that silly Set Home Offsets does o_O. Great videos; very clear and easy to follow!
I figured it out by re-watching the video. Thank Great info
Awesome! I'm building an IDEX printer now and just got my E3 RRF board along with the IDEX and TFT35 for it. I'll have to keep an eye on your channel!
Thank you for your information it was incredibly clear and helpful and I’ll be definitely keeping an eye on your site for further information on 3D printers
So professional. Good video.
I love your OKAY, lol. Great video as always!
Your videos makes me want to make a number of upgrades to my printers. Good thing, the upgrades are quite affordable. For my original CR10, I think the next upgrade would need to be print bed, rather than the controller board. It is soo slow to heat up. Although silent steppers would be nice too.
AWESOME video!! I will be ordering this today. you are the reason i got the sv01

@@AuroraTech I ordered my printer the day you posted the video about the assembly of yours. My coworker is getting his sv01 this week ill make sure he uses the code. i cant wait for the next video! Yall rock and deserve more subs. Take care and keep learning!
Love the way that u explain things better than ather pros 👌😎😇
SUPER vidéo, merci
Great video as always
Thanks for sharing :-)
Like it, love it. I got some answers what I couldn’t found out so far 😅 still stuck a bit with my Ender 3v2 with the BTT TFT35 landscape. It wound connect and says no printer 🙈🙈
Excellent. Subscribed
Fantástico preciosa, mejor explicado que cualquier guru 3D printer. Lastima que no este en español, pero eso seria la perfección total.
super, you are the perfect daughter any geek father would like to have. congratulation. it is very clear
Amazing video!
Do you have any intention on making a video about setting up the IDEX board with an additionall extruder and stepper motor?
Great videos keep up the good work. I was following your guide and found that on my ender 3 pro with the cr touch installed the firmware that worked was the one that says z homing. all the cables are connected to the mb probe all 5 pins. i tried first with the one that only says bltouch and it would not home z. Z would only go up each time I tried to home it. Z homing file worked perfectly. Now I'm trying to compile the latest version of marlin without screwing this up.
Thank you for sharing
Love will win, fear will not - Love fear 💖 than Love will always win 🙏
Great upgrade video. Thanks!
I wish there was an SV01+ with quiet steppers and the BL Touch. I'm actually very happy with the SV01 so far. Hard to beat the print quality. I hate fiddling with the tiny microSD card.
My new SV01 had the hot end heater burn out after ten hours. I assume it's just a random initial part failure. On the plus side, the heater quality looked good, spare parts are inexpensive and readily available, and it's easy to maintain the printer because of the open architecture.
That's strange, you mean the heat cartridge burn out? You can ask Sovol for a replacement.
@@AuroraTech - I contacted Soval via Amazon a week and a half ago, when the hot end heater burned out after ten hours use. I was told I'd hear from them in 3-5 days but never heard anything. I would contact them directly if I wanted a response, but I bought five replacement heaters for a couple of dollars each - 40W and 24V so electrically equivalent but not nearly the quality of the original. They were the best I could find on Amazon. The wire gauge was much lighter so there will be more electrical losses in the wires which will limit the hot end temperature slightly, and the wires were only 1m long so I used inline quick disconnect connectors so I won't need to replace the heater all the way to the motherboard to make repairs easier next time (no need to flip it over). The printer has been working great, printing 21 hours a day for the past week. The nozzle has no problem quickly reaching 230C.
I'm loving this little printer with the large build area. Great print quality, and easy to maintain. The extruder is excellent. It's simple and easy to load and prints flexible filaments very reliably.
I also switched to the Prusa slicer last week and it's my favorite slicer. I like it better than Simplify3D, Cura, IdeaMaker, etc.
Woooo you are great.👍👍👍👍👍🙌🙌🙌🙌🙌🙌🙌🙌👏👏👏👏👏👏👏
Thanks for doing a video on the SV01 again Aurora... And really interesting choice of board! I have an SKR 2.0 + 2209s on order from BTT, but it's not even shipped yet. I'm now second guessing my decision!
Also looking forward to seeing your update about the dual Z driver and G34. I've been using this setup with the v2.2.1 board now for a couple of weeks and it's working great. It's really interesting to see how much correction is needed for the Z axis. If I've been fiddling with the printer, particularly if it was on its side because I had the bottom open for some reason, the Z axis will be off by up to 0.5mm when I set it up again. Usually though, if it's just been powered off overnight, it's still off by 0.2mm at the start of G34. I really think G34 improves the accuracy of this printer.
By the way... what are the clips you're using to hold the glass to the bed? I like the clamping force of the binder clips, but as you showed, they're huge. I'm currently using some picture frame clips, but I don't like how they clamp. The ones Creality uses for the E3 V2 look good, but so does what you're using.
You can take a look at amazon:

Actually I think the second one holds better, the one I used on the SV01 always pop off when I remove prints from the glass bed.
Great, thanks @@AuroraTech!
@@AuroraTech I've been using the second ones for a couple of months now and have not experienced any problems. Where did you get the x and y axis belt tensioners?

@@AuroraTech Thanks Aurora. You and your brother are doing great. Keep up the good work.
I followed your instruction that were very well explained. I put the board in my standard Ender 3. when I turned the printer on the screen lit but no information was displayed only a lit blank screen. What did I do Wrong
Does setting the home offsets affect the BLTouch Z offset? I did this and everything worked great but I must have done something off as it pushed the print head down too low and scratched the glass bed surface. I re-did the Probe Z axis offset and got a new value and updated it and then it was fine.
Hello, I have two questions as I’m considering buying the sovol sv01 printer. What kind of nozzles fit this printer? Also you said that this printer fits any creality drop in boards, could a creality 4.2.7 board be put in this printer (obviously firmware would have to be compiled using similar steps to your video)?
Just did this exact upgrade. This video helped a lot! When I home the X axis, I get a value of -9. Is this normal, or should this be 0?
You can try to print a line on the left edge, if the position is correct, I think you are good, if the line print outside the bed, you may need to set a home offset on the LCD screen.
Edit: just finished the video, and you are already planning this for a different video. :)
Would be sweet to see you use that expansion "idex" board to use 1 for each of you z motors, that way you can use g34 z axis stepper motor auto align. :)
Im excited for this too. I have been struggling to get mine setup that way.
If the board is made for the reprap firmware, why you don't install this? It would be ncie to see the guide with reprap and using the full wifi webinterface.
good afternoon, I would like to ask how to install this card on ender 3 pro is it self-installing? as I read that it does not need to compile the firmware but use it from bigtreetech, could you tell me whether to use the dedicated firmware this card for Ender 3 or other? thank you
my X axis is not storing the homing position, every time i repeat the auto home, the printer uses the actual position as home. any ideas why?
yestersay I got mine from amz, but i havnt a touch screen display :-( RepRap for ender3 display is awful , i'm affraid about sensorless homing i don't know how it's works.
Hi, can you do a 32bit board upgrade on Sovol sv02 please?
I just installed the board and firmware on my SV01. But when a print completes, the build plate moves forward so far that the stepper motor grins until I turn the power off. Any idea how to fix that? Thanks!
That's mostly in your end gcode on your slicer. Like a "present print" line of some sort. Check your end gcode at the very bottom of the lines for some kind of Y motion.
very curious, is this board capable of dual z stops to assist in keeping the hot end gantry level ?
Yes, if you also have the IDEX extension board, you will get another 2 stepper drivers to control the second z axis, so you can use G34 to do z-align. I have another video for that:
th-cam.com/video/QHblq2AReqQ/w-d-xo.html
@@AuroraTech YAY!!!! thank you so much!!!! I truly appreciate it !
Hey there about how long will it take to update the fw? Also for some reason my printer goes wild and tries to run off the bed, did i do something wrong?
It would take 10-15 seconds to upload to the printer after you inserted the SD card with the firmware.bin file.
You have the exact same board BigTreeTech E3 RRF, right?
If your Y-axis didn't stop when it reaches the end, that means sensorless homing is not enabled or the SENSITIVITY value is not right for your printer, how about the X-Axis?
You may need to check:
1. define SENSORLESS_HOMING is enabled in Marlin
2. For my printer, SENSITIVITY for both X and Y are 60, you may try to adjust this number higher to make it more sensitive, you may start with 100, 90, 80... keep decreasing the number to find the perfect number for your printer.
3. Make sure you put 2 jumpers under the X and Y stepper drivers on the motherboard to enable the sensorless homing feature.
@@AuroraTech life saver lol I must have missed that. Now I’m having a problem where the printer resets midway through prints. I suspect overheat protection. I’m not sure tho, I’ll add another cooling fan today. Any other ideas?
Can you pleas bo this for the svo2
First print on my DIY IDEX build, just using one extruder so far: th-cam.com/video/lwBivg6Tg40/w-d-xo.html
Anyone else with this board have issues with SD on-board reader???
I'm reading a ton of people having issues. Usually from people running Marlin.
Edit*
Yeah. The SD card slot is junk on these. Many post online.
But works great if you utilize the SD and USB reader on the TFT. Or use octoprint. Or whatever you want with the wifi.
Um - are we allowed to petition for technical corrections, or will EweToob get all uninate-ey about spreading TRUTH???
It's REPrap, NOT raprep!!!
