Hey everyone,

I am working on my mainline SV08 with an XOL toolhead and I was finally able to get it to work without throwing a ton of errors. This being said, I cannot get my part cooling fans or my heat-break fan to work. Double checked the wiring on both and everything is going to the correct headers (to my knowledge) and I am just not sure what is going on. When I try and turn the part fans on in Fluidd, they do not turn on, and when I raise my hotend to above 50C (usually 55C to test) nothing happens. It says 100% fan speed for the heat-break but the pwm says 0 RPM.

I am unfortunately a novice with this stuff, so any help would be greatly appreciated!

I got most of this .cfg from a similar setup off of github and I adjusted everything that was different with mine.

Hardware:

EBB36 Gen2

Dragon Ace w/ PT1000 thermistor

dual 4010 blowers (2-pin)

3010 heat-break fan (3-pin)

Hello everyone,

I started modding my used SV08 a while ago when I tried to adjust the belt tension on the stock injection molded gantry parts. While adjusting the tension, one of the heat-set inserts pulled out of the injection molded part, so I decided to print the Nadir's 3D printed gantry upgrade. https://www.printables.com/model/1400767-sv08-gantry-v2-precision-easy-tensioning

After printing this out of PET-CF and doing the double-shear upgrade, I noticed that the motion system felt very very tight. Like the toolhead was difficult to move by hand, and I noticed that the pulleys fit very loose. There is a lot of slop in them up and down and they do not run true on the belts. Now, I am considering buying the CNC gantry kit from Funssor Lab https://funssorlab.com/products/preorder-sovol-sv08-cnc-machined-xyz-kit-designed-by-nadir?VariantsId=10459

Does anyone have this installed? Thoughts?

*I am also running an XOL toolhead, not sure if this will impact anything*
