Slice support has been discontinued by Voron Designers since Slice came down on small Voron dealers over their Mosquito patent (which is probably invalid due to prior art), and the Mosquito heater block is so wide it tends to radiate heat into and melt parts cooling ducts. You will have better luck with other hotends on the Voron.
I got a Mosquito with the Railcore, I'm going to use it there.
The Rapido is Phaetus's answer to the Revo. It looks good and uses standard nozzles which is nice. It surprisingly costs slightly more than the Revo which is unusual for a Chinese product vs a UK product. But the savings in nozzle replacements will be substantial, and the variety of available nozzles for the V6 ecosystem that works on the Rapido is useful.
