I got 2 new springs from Carbide the other day. It seemed to help a little but I ended up going only using one. I got better cuts using the 1 spring. Also I had my dewalt all the way down in the craddle. I moved it to half way and that may have helped.
I wish there was a counter balance, I think the Z motor is working to hard and with the added springs it doesn't help which cause it to slip or not have the power when 2 springs are attached. I think some more though in the design is needed on the Z axis.
I emailed support about the position of the router in the collert to find the correct postion because nothing states were the router should be.
They indicated it is a preference but there is some chatter in the system if the router is at the bottom or all the way down in the collar. they also indicated because it is a preference it will depend on your cutting surface and how far down you want to cut as well.
This is what I got from William from support
The vertical location of the spindle is a balancing act, and a matter of some tradeoffs:
- further down makes reaching the work easier, and allows for one to work on thicker stock, or with a thinner spoilboard --- but increases lever effects and may increase chatter along the Y-axis
- further up pretty much requires a spoilboard, or limits stock thickness --- but decreases lever effects and will make chatter less likely
I hope this helps!
Please let us know if there's anything else which you need!
