Extruder For Filaflex

#1
Hi everybody

I have some Filaflex filament from Recreus Spain. I like to print it whit the Gmax and no change mi prusa I3 extruder for continue print ABS. I must download and print a special extruder carriage for the Filaflex for the prusa but, what happen whit gmax? How I can use this new filament ?
Maybe I must remix the extruder carriage whit freecad or similar ?
Does anybody try print flexible filament ?

And other question is in my mind is how I print ABS whit the Gmax 1.5. I try it whit my other print whit no very good results. I try whit the bed completely cold , whit acrylic sanded and taped and not very good results. I know PLA and Filafkex don't need heatbed but ABS ??

Thanks everybody
