When I saw the “Why not put a Zero tool head on your SV08?”, I was prepared to explain to the noobie that the SV08 motherboard uses USB and the Zero tool head is CAN bus, then I saw you were the one asking the question. Tell me more!
A USB to CAN bus converter. Well, ain’t that clever? Cheap too! That actually looks like a much better solution than my desperate plan to buy an SV08 Max motherboard and tool head to upgrade my SV08 if Sovol drops the ball on the Eddy upgrade, although Eddy on the SV08 now sounds imminent.
I print a lot of TPU and the slightly shorter melt zone on the SV08 seems to print TPU-LW better than the Zero hot end, so I’m inclined to keep the SV08 extruder with the Microswiss hot end, but I’ll be very interested to see how the Bondtech INDX inductive heating will work with TPU. I don’t print fast so I might be inclined to put INDX tool heads on my Zero and SV08.
I have step models of pieces to drop the heatsink on the Zero 9mm to allow use of ANY SV08 hotend. You’ll have to layout and install a threaded insert into the extruder plate 9mm below the existing one. The hard part is the Zero expects a PT1000 not a 10k thermistor. Sovol made the cavity in the ZERO heat block larger to make room for a bigger sensor, I don’t think it would be possible to put the Sovol PT1000 into the MicroSwiss hotend. Triangle Labs has a PT1000 for their SV08 hotend but I can’t find any information on how big it is. Wire length could also be an issue with the heat block being 9 mm further from the board.
The Zero will work if you change the config file to a 10k thermistor. The pullup resistor, however, is optimized for the 1000 ohm RTD so you are going to give up some accuracy if you go that route.
As far as I know, yes. Little to no documentation for Linux systems. The CAN interface needs to “attach” at the OS level so when Klipper sends a CAN message the OS knows what to do with it.
I THINK it will “just work” with a recent Kernal. I Don’t have a SV08 to try it on.
The documentation on MKS’s github does talk about a couple packages to install but I think those are to enable advanced functions.
There are about 100 other USB to CAN devices out there. I picked the MKS one because they built the SV08 mainboard. I assumed maximum compatibility. MKS however has the WORST documentation and customer support.
It just works ifbyou hook it up right, google canonical canbus guide, I used a different toolhead, so I can’t vouch for your setup, I used dragonburner biqu sb toolhead w can 2209 for my application and the U2C allows it to work.
This thread was referenced in tonight’s Sovol live stream on YouTube.
It was the third live stream tonight, after two internet drop outs.
Ben said he thought they should already be finished with an SV08 tool head with Eddy probe but they still don’t have a release date for the upgrade for existing SV08 customers, but hopefully soon.
I also hope this is an indication that there will soon be an SV08 Ace, with the Eddy equipped tool head and a thicker bed that doesn’t have a taco bed. I think that will be a great printer… much like what the great SV06 Ace was to the good SV06.
Thing is…CAN aside, if the SV08 ACE is more than £150-ish over the vanilla SV08 price, you’d be better off getting one of R3men’s graphite beds and an Eddy Duo, and the mainline process is no more difficult than the process of upgrading the SV08 firmware anyway.
Of course, I say that with the graphite bed still sitting in its box after it arrived two weeks ago. Maybe I’ll get around to it tomorrow…
My R3men graphite SV08 bed just cleared customs. I should have it this week. Come on Sovol! I need that Eddy toolhead!
MK8. I bought three more from Microswiss yesterday at their Independence Day sale, partly in anticipation that the SV08 Eddy tool head may use the same hot end as the Zero and SV08 Max.
As far as I can determine it USES the same tech as EddyNG.
The build plate has a force sensor which Sovol disabled in the 1.4.x firmware. Out of the box it now uses nozzle taps to calibrate the eddy. By not using the force sensor the toolhead should function on any printer with a metal build plate.
Hi. I have two SV08’s with the official inclosure. From day one I have had endless problems with the toolhead either loosing connection to the motherboard because of either a fault in the wiring loom or the toolhead boards going faulty. I reily hope that Solvol release updates that will allow me had others to use the toolhead and CAN wiring from the Zero so finely I can have a printer that I can rely on. I have already purchased the Zero toolhead and would purchased the wirings loom in a heartbeat. So please Solvol hoo yourself and us all a favour and release this upgrade path for your loyal customers.
Regards. Mike Irish
The wiring loom should be fine. Unplug the toolhead USB plug at the mainboard, splice on a short extension and hook them to canhi and canlow on the converter.
The hard part is splicing together a printer.cfg file. The QGL macro will have to be reworked to use the eddy instead of the probe. The Tap to Zero function should transfer easily. Probably a couple more issues I’m overlooking.
