Hi Mark,
Filament printers wise I've been working with Ender 3's Cr10's and Bambu A1's using Cura, Chitubox and bambu Lab slicers for the past 5 years or so!
and availability wise, I'm free up to the 13th and then from the 17th (next Wednesday) onwards up until the 21st. After that it would be January.
Hopefully we can slot it in before then but no rush!
Dan
