SV01 PRO...... BROKEN hot end , replacemt?

Well as able to find a board on ebay for $60. But while i was cleaning up my work area, i happened to look at one of thr extra hear cartridges i had ordered… hard to see , but lazer engraved on it 12v 30w… sigh…the ad was clearly for 24v. I dont think this is my problem as it should not effect the readings i was getting from the thermistor. I tested both thermistor as well the bed and nozzle and both read 115k which is right for the temp my room.

Still scratxhing my head about what actuallg happened . But fingers crossed new board will fix it. Will find out in about 3 weeks

Hot End Heater Cartridges: A No-Nonsense Guide

Well I stand corrected !

So i think we have probably found the mystery as to what happened !

So what did I learn from this . Always double check products from amazon, even if u know that YOU ordered the correct part. What they sent could be different !

Well the new / used mainboard arrived today ! Swap it over and flash with the sovol website firmware.

Fingers crossed.

Yes i did get new heat cartrdiges that are labled 24v 40w!

New board is in ! . Everything seems to be working. But the machine is louder then it was before? I did performed a bed level and noticed that the extruder motor was gettting very hot , with out extruding any filament? any thoughts about that?

Did you ever ger your machine sorted out?

I’ve changed my SV01 Pro over to a V6 full circle hotend. Have to use the Sovol heat break (8mm dia) but other than that it works fantastic.

Note V6 nozzles have more threads and less tip. Same length as the MK8 but the MK8 won’t seat correctly.

It is such a joy to unplug the wires and drop the hotend free.

I got the machine up and working . Its now running a skr e3v3 mainboard with klipper. I have the sovol all metal heat break as well. But lately i cant seem to keep the nozzle tight enoign it keeps leaking around the heating block. I am guess the threads are damamged . Im interested in the v6 swap you did.

The link posted is the new heatblock / hotend you used on the stock extruder ?

Link is for the heat block with heater and thermistor but don’t buy that one ($46 shipping)

Is free shipping and long wires (I had to splice mine)

Also on Amazon (short wires).

Stock Sovol heat break screws into the top.

V6 (not your old MK8) nozzle required.

Side note: The torque retention issue is the same for the V6. The joint was designed around a copper heat break and a brass nozzle. Both are soft metals. If you use a titanium heat break and a (solid) hardened steel nozzle you now have 2 hard metals against each other. If you need hardened nozzles look for bi-metal ones with copper bodies and hard inserts.

Awesome! Thank you , i did just order some mk8 cht nozzles ! Doh!

But i can use those in my sv06.

Im going to do this, i really like the 360 design and i like the longer threads of the v6 nozzles. More time heat up that filament !
