Has anyone upgraded their k40 with MKS SBASE board?

Has anyone upgraded their k40 with MKS SBASE board? It’s different then smoothie but uses the same firmware. But while looking at it I noticed there’s a jumper for 3.3volt and 5 volt would this mean I don’t need the logic converter?

@Derek_Schuetz ​ I have a azsmz board that does not appear to need the logic converter. I have being able to run the laser without power control and in the middle of connecting power to finish. Just at the point where laser always fires

@Ariel_Yahni_UniKpty could you send me some picture or a quick diagram I can follow. That board is different then mine. I didn’t get that board because it was a 12v so i got the other one that can do 24v

mine is 24v also. Post a pic of your PSU and nano board
