Eddy for SV08 without mainline hassle

That file is only about 1/5 of the complete file to operate the Zero TH on the SV08

Thank you for your interest. have you tried to update your printer config using these changes, and do the work for you. It’s hard to find a complete set of changes needed to complete the changes required. If only someone more familiar with these programs could find the time necessary to put together instructions for us poor old kodgers :>} I reild can’t understand whySovol hasn’t put together an update package for this printer. I’m sure that they would save a lot of time and money trublechootingand sending outpars to us? wouldn’t it be more cost effective to have an engineer spend a couple of hours on this task?? Also think of the amount of us SV08 owners that would jump on the chance to take the upgrade path.
We’ll rant over. I hope Solvo sese this and takes it on board.
Cheers. Mike Irish.

Sovol is naturally focused on their new Zero and SV08 Max products, which directly benefited from customer feedback on the SV08 deficiencies. I do think Sovol owes their SV08 customers a fix for the taco bed and inaccurate bed mesh issues. I’ve politely asked about the Eddy upgrade on every Sovol live stream, and I frequently comment under their SV08 Max YouTube marketing videos, inquiring about the SV08 Eddy upgrade.

I’m an engineer, so my inclination is to fix the problems myself, but I don’t want to spend a few days to correct the SV08 issues only to have Sovol offer a better $100 upgrade the next week. My SV08 has been down for upgrades for over three months. I’m hoping it’ll be reborn in an upgraded form that lives up to its excellent potential, sometime before its first birthday. That’s probably half or a third of a 3D printer’s useful lifespan, given how quickly this technology is improving.

On the plus side, the little Sovol Zero is cranking out the parts. It’s a great little Goldilocks printer. I always gravitated to larger printers for more flexibility, but the Zero prints most of my parts and it’s a very solid little printer with great print quality even at higher speeds, low power consumption for the 150x150 bed, and the small heated chamber heats quickly making the Zero a great little ABS printer.

At the end of tonight’s Sovol live stream, Ben mentioned the long awaited Eddy upgrade tool head for the SV08… without me even asking this time. :smiley:

Ben said it’s “very very close”. It’s basically complete and in stock but they’re finishing a few details before releasing it. Based on Ben’s comments over the past weeks, I wouldn’t be surprised if Sovol is selling the SV08 Eddy upgrade in a week or so. That will be a good day.

Yes it is. The sensor is quite good on the zero toolhead. (And no, sovol didn’t actually use eddy-ng, they hacked in their own nozzle touch sensing.)

Note however they in order to get the zero toolhead working with eddy-ng (or with any self-compiled) firmware, it will require a patch to klipper to fix I2C communications.

Well, that’s slightly annoying. As it is…if I need another printer (which may be the case soon), I’ll probably just buy another SV08 (maybe it’ll get discounted if they bring out the ACE version?) and apply all my mods to it. Eddy Duo, Micro-Swiss nozzle and R3men bed, then just copy the eMMC card on my existing one, tweak the device IDs and flash the MCU firmware.

I have done the mainline conversation to 3 SV08’s now by copying the image. And as you say change the ID’s and flash the MCUs. It works great. I went with Eddy duo and Demon Eddy along with Demon Macros. Also installed the MS hot end and an R3men graphite bed and getting extremely good first layers now and better quality prints.

Hi all. Well I have the tool head for the Zero now and I also got the CAN Board, I didn’t order the CAN lead as I intend to use the one in the Zero toolhead. I was hoping that someone would have the .CFG files sorted by now, but unfortunately that doesn’t seem to be the case? Maybe someone has sorted it but just hasn’t had the time on hand to post it? If someone knows anything about any progress please post it here and let us know.
Cheers. Mike Irish.

I haven’t tried as it hard to do without a test machine.

Make 3 folders so duplicate file names don’t overwrite. Name them zero, SV08, and SVZero8. Copy the cleanest newest /printer_data/config folders you can find for the Zero and the SV08

I’d copy both printer.cfg files into 2 columns of a spreadsheet. Drag things around until the section headers are all aligned. There will be long gaps in the Zero side when you get down to the Z Axis motors. Copy the cells that are valid for the hybrid machine to a 3rd column. Copy/paste the 3rd column to a text editor and save as printer.cfg into the SVZero8 folder

Repeat process for macro.cfg and any other “included” cfg files

Debug

I THINK using the [Probe] section from the Zero will make the QGL macro work with the Eddy… But I may be mistaken.

I believe the CAN UUID for the printhead is hardcoded and will be the same for every Zero toolhead but again I could be wrong.

Wow you sure are familiar with Clipper. I would just love to have the confidence to change all those settings. It has me scared Sh!tless just reading your reply. :scream:

Put a cookie sheet (or similar) over your build plate and the worst that can happen is a ruined nozzle. The Zero uses the most common one in existence. Buy a dozen junk ones on amazon.

The motors aren’t actually strong enough to hurt the printer frame or gantry but they can make some horrible sounds.

Whatever you put in the cfg file has to pass Klippers error checks. 95% of errors you could make are never going to load.

OH… Never leave the room with the heaters on until you are POSITIVE they are hitting and holding their set points. The heaters do present a small risk of fire. Smell scorched plastic, pull the wall cord.

You are not going to CHANGE any settings, just copy the ones you need to a new file.

BTW I’ve had fair results with CHEAP brass nozzles and PLA. Name brand do print better but until you get the printer working stick with the throw away ones.

Thank you for all your help and advice, I truly appreciate it.

On yesterday’s Sovol live stream, Ben mentioned that the SV08 tool head upgrade is the same as the existing SV08 but with an Eddy sensor, so it will presumably use the same hot end and nozzle and will remain compatible with the Microswiss FlowTech hot end for the SV08. It’s apparently close enough to shipping that I’ve been reloading the SV08 Accessories page on the Sovol website every day to see if it’s there, but I’m an optimist. :slight_smile:

ANY CHANCE OF A FLAT BED, not a Taco

SV08 but with an Eddy sensor, CAN NOT FLATTEN THE TACO BED on the SV08

The upgraded SV08 will have the 8 mm thick aluminum bed of the SV08 Max. The 350x350 mm bed on the SV08 will have a greater thickness to area ratio than the same thickness on the 500x500 mm bed on the SV08 Max, so it should warp even less than the SV08 Max which doesn’t have the taco bed problem of the SV08. Sovol may also have learned about mounting the aluminum bed to reduce warping. Hopefully, Sovol will sell the upgraded bed solution as an upgrade to existing SV08 owners.

My graphite R3men bed arrived last week. I haven’t installed it yet but it looks very nice. I’m waiting for the soon to be released Eddy tool head from Sovol. In my mind, they’re a package deal that completely fixes the first layer issues on the SV08. It aggravated me to pay to get a bed that doesn’t warp, but this is just an issue of improving technology. It’s no different than buying a computer and a year later a better computer costs less money.

It’s going to be great to have an SV08 with that large build area and have a flat bed and a fast and accurate bed mesh. I designed and 3D printed an enclosure. I need to finish the front door and upload that to Thingiverse and Printables now that SV08 owners can have a flat and well compensated first layer needed to accurately and reliably print these large parts. I’ve talked myself into adding the Bondtech INDX when it becomes available (estimated November 2025) and then I’ll probably design and build a 4 or 8 spool heated filament drying box to feed the filament into the SV08. It’ll be a very modified SV08 when I’m finished, but I’m very happy that people will be able to buy an SV08 with the initial first layer deficiencies corrected without additional upgrade cost in money and time.

If your graphite bed is as good as they claim there is no need to mesh every print. The stock prox sensor will map the surface very well if you halve the spacing.

I use Christian Vick’s macros on my SV07. The cool thing is they build a library of meshes at different temperatures. I generated 10x10 meshes for bed temps from 40 to 100 °C one time. The start print routine reads the bed temp from the gcode and loads the correct mesh.

The 6 meshes took about 3 hours to do using the stock prox switch (with a 10 minute soak at each temp) but I have not run a mesh in almost 4 months and have no first layer issues.

Meshing before each print is only needed if you are constantly changing build plates or abusing your machine and knocking it out of alignment.

I don’t care how fast an eddy can scan, it still takes longer than reading a mesh from the cfg file.

Point is the problem with the SV08 was NEVER the accuracy of the prox switch. The problem is the bed changing shape AFTER the mesh was done. If you have a bed that is rock stable you don’t need an eddy to have a useful, reliable, printer.

Storing accurate bed meshes from repeatedly slow probing each point and taking the median for each temperature is some appropriate engineering. A single macro could do this once for each temperature and you’d only need to do that when moving the printer, changing the build plate, etc.

There is something cool about the Zero when I can swap hot ends, change nozzles, use a different build plate, take the Zero to a friend’s house, et cetera, and it’ll automatically recalibrate everything in a few seconds at the start of each print. That can save me from forgetting to recalibrate after maintenance. As long as I don’t forget the steel build plate, it should be good.

In the case of the SV08, I wasn’t looking for partial measures. I became frustrated and decided that I wanted to drop a thermonuclear bomb on the first layer issues.

You keep lamenting the lack of use of your SV08. No reason you can’t bring it online sooner than “shipping soon”

The SV08 Eddy has been “shipping soon” for 6 months… Is the wait 90% over or 0.9%? I guess we’ll know soon…
