Hello,
Couple month ago I bought 1419 machine. I really like how it's built. Just out of the box I was able to achieve pretty good results (flatend mill 0.3-0.5mm).
But there are two problems I have:
1) Spindle is noisy. It's Chinese 775 engine.
2) Collet accuracy is far from to be perfect. Every time I spend 15-20 minutes locking, unlocking, rotating collet, etc. to get rid of runout.
I tried to replace OOTB spindle with 20k rpm version from genmitsu -- not a lot of difference (just less noisy when running at 10-12k rpm)

Now I'm looking to try brushless 104W spindle: https://www.ebay.pl/itm/115475403851...dgZlh#shpCntId

Maybe someone has experience with this one?

Why 104W only? I need CNC for two operations which do not require a lot of power: pcb milling and guitar pedal enclosure engraving. Milling and engraving speed is not really important. I can wait 20-30 minutes without any problems. This spindle is equipped with ER8 collet. I expect it will have better runout than on my 775 spindles.
Machine itself is pretty compact, I don't think I need large heavy spindle. Wegstr machine uses 26W spindle and they even cut aluminium(I think they do that very slowly, with small diameter bits, but... looks like it's possible if really needed)
