SV08 updated toolhead and bed...when?

Sovol SV08
1

So…Ben said in a livestream that the upgraded/fixed eddy toolheads and beds were ready in July…it’s now mid-October, and we still haven’t had any news.

Does anybody have an inside track on what’s going on? I’m in a position where I’ll need another printer very soon, and I’d very much rather get all the stuff from one place instead of cobbling together from Sovol/R3men/BTT/etc. Even better if there’s an SV08 ACE on the way, to save me all the hassle of mucking around in there myself.

EDIT: OK, I see they’ve got the eddy current scanning kit up for sale now! That’s half the job…

Hello,

So, what are you waiting for now?

3

An updated bed - last I heard, they were putting a kit together that used the 8mm bed design from the Max.

4

I have a R3men bed and I will not go back to aluminum the graphite will not move under normal print temperature.

I just installed the Eddy kit went in easy just make sure you are running V2.4.6 before flashing,

or you will have issues don’t ask me how I know.

Yeah, I’ve got the R3men bed on my current SV08 - it’s damn good, won’t lie. With that said, I’m looking at the total cost of the SV08, eddy scanning kit, R3men bed and Micro-Swiss hotend (£630 total plus a fair bit of work and a voided warranty) versus an SV08 Max (£821).

Flip a coin, I guess…unless they do actually make an SV08 ACE after all this.

EDIT: Actually, I’ve got a third option…I’m not 100% convinced that the BTT Eddy I’ve got is configured properly and the mount is a bit sketchy. It would also be useful to have both printers set up identically. I could get a second SV08 with the upgrades above, and get a second eddy scanning kit to replace the BTT Eddy Duo on my current one. That might simplify my workflow.

The Eddy scan kit is a great upgrade they have made the install easy and for the price here in the US is $44.00 is a cheap upgrade with a wealth of advantages.

7

Quick question, actually - how does the new firmware with the eddy sensor calculate the Z-offset? Does it use eddy-ng, or is it a manual process, or something else?

8

I’m not 100% sure it seems like it senses the load on the Z motors as the nozzle touches the bed like homing like the X and Y axis, It works very well after running the calibration I brought the Z axis down till it touched a piece of paper and Z axis position .1mm above the bed.

9

OK…so that sounds like the eddy-ng behaviour, which is a good sign. I’ve found that method to be a bit unreliable in my current machine with the Eddy Duo, but it’s a lot better than the original method.

I’ve ordered one - I’ve still got the eMMC backup from before I mainlined the machine for the BTT Eddy Duo, so I should be able to reinstall that and go through the procedure in the manual. Let’s see where this goes…

10

It uses the same process as eddy-ng but is a stripped down proprietary version.

The nozzle MUST be clean for good results. See the Zero thread as (as far as I can tell) the process is the same.

11

Yes it is the same, it will go through a nozzle cleaning cycle before a print starts.

I also have a Zero that I put a .2mm nozzle in to do small prints with a .1mm first layer no dragging on the bed seems to be a good means for Z offset.

I’m very new to Klipper all the other printers I have built are RepRap Duet3D controllers, as for my SV08 I have added the R3men bed, Microswiss hotend , Funassor CNC grantry kit, 7’“ BTT HDMI screen, as you can see I can’t leave anything alone.

I’m working on a mount for a LDO orbiter extruder for my SV08.

I’m thinking when I get it done I might pick-up another SV08 an convert it over to a Duet3D controlled printer just for fun.

12

Do you have links to the gantry kit and the bed?

13

Can’t help with the gantry kit, but this is the bed:

Be warned that connecting up the heater involves fiddling with mains AC wiring, so if you’re not confident with that then it might be an idea to grab somebody who is - as I recall, the instructions are somewhat vague and require the use of some imagination.

14

Will this bed work with an Eddy sensor?

15

Yup, works fine with my Eddy Duo.

Here is the link to gantry kit

Oof, that ain’t cheap. With all these upgrades, the SV08 wouldn’t be far off the price of a Ston Wolf (which, I’ll admit, has somewhat caught my eye).

18

I would say that I have spent what the printer cost and then some on upgrades and mods.

But I do this just for the fun of it.

19

Aye…I’m using mine to batch-print functional stuff for sale. My problem is that I need a perfect first layer surface, and that’s proving surprisingly difficult even with a R3men bed and Eddy Duo with eddy-ng. Trouble is, I have to have a minimum of a 300mm build surface for these parts, so my options are seriously limited (particularly since I won’t touch Bambu).

With that said, I may have made a discovery…part of my problem seems to be printing the first layer too slowly…but that’s a subject for another thread.

20

So far I have no first layer issue now with the Eddy kit from Sovol I did before with the probe always had to step it +/- .1mm or so.

Using PETG-CF I use first layer height of .25mm with a .4mm nozzle and running a single layer measuring the thickness it is .238mm to .242mm close enough for me.

The speed I use on first layer is 30 on perimeter and 90-100 on the infill.
