Spindle too heavy?

[EddyCurrent]

Would you put a tractor engine in a mini ? put the old spindle back in and either use it like that or sell the whole machine to be replaced with something larger.

Old spindle died, which is why I bought the 1.5kw ready for the upgrade.

I will counterbalance it for now, only needs to last another 4-8 weeks while I order the rest of the parts and build it. Is there a method to choosing a spring or is it just trial and error. I reduced the accel to 50 today and it did a full 3d job just fine and the noise wasn't too bad but noticable. I also cut some Aluminium for the first time and I'm pretty please with the result. This machine will be my fulltime foam cutter once the new one is up and running.

Cheers for the help guys, Isaac
