I have rebuilt my Omio X8-2200L-USB with a CNCdrive AXBB-E ethernet motion controller and then running UCCNC. Prior to conversion I had problems with loosing steps, now it works really nice. However I haven't managed to get the CV settings right, I have experimented and it doesn't jerk in curves as it did but holes sometimes don't get exactly round.

Have anyone suggestions on the "right" CV settings?

Mine are:

Comm. buffer size: 0.1
Exact stop mode: unchecked
Constant velocity mode: checked
Stop att angle degrees> 89
Look ahead line conunt: 300
Linear error max. 0.1
Linear addition length max. 15
Linear unify lenght max. 35
Corner error max. 0.03
Arc radius tolerance 0.1
Enable softlimits: unchecked
Softlimits file precheck: unchecked
Unknown g-codes action: only Ignore checked
Reset on file load: not any checked
G41/42 round joints: checked

Are you using fusion 360 for the CAM ?
I do and when unchecking “smoothing” in the post processing settings or the selected tool path options it’s getting better.

Excuse my English hope you understood me well

I'm using Fusion 360 so I will try this. Thanks!
