Re: Rough Motion on Circular Toolpaths
Update. I disconnected the rack and pinion drive gear to test the linear rail movement. Super solid and smooth. Then removed the servo/belt/pulley/gear assembly and tested in isolation: Vibration. Then disconnected the servo motor completely to test it in isolation. And the servo is the culprit! The...

Re: Rough Motion on Circular Toolpaths
Open the oscilloscope function of your servo. Measure the frequency of the ossilation. And use the built in notch filter to remove that oscillation. At least, that is how it works wirh delta servos. All indications, to me are servo tuning related. Interesting. I’ll look to see if the leadshine serv...

Re: Rough Motion on Circular Toolpaths
May have found something. I get a bunch of vibration at certain low feedrates (<80 ipm) in the X axis. the chatter marks on my parts line up to where the x axis is at slow speeds for the circle. So yeah seems it is not a centroid issue. Keith, do you think this is due to the gearing? Anyone dealt wi...

Re: Rough Motion on Circular Toolpaths
Happen to be running servos? I have had issues before when using a gantry and servos that when you have a machine which is not very stiff, thus servos cant be really tuned to be very dynamic. Then when you do quick circles, it does not go as smooth as you would have hoped. But all aims at mechanics...

Rough Motion on Circular Toolpaths
Hi friends. Acorn Board on a CNC Router. Been Struggling with rough motion on circular toolpaths. Machine sort of shakes, causing bad surface finish. IMG_4604.jpg I have smoothing turned off Here is the GCode on one of the rough toolpaths: N135 G17 G2 Y-1.625 I0. J-1.625 N140 Y1.625 I0. J1.625 The r...

Swissi's Fusion 360 Probing Functionality
Just wanted to come on here and say that Swissi is the man! Been working with him the past few weeks to get the Fusion 360 probing functions dialed in. He has been super responsive to my requests and got everything working great! Above and beyond! Go buy his ProbeApp and thank me later :) Cheers, Mi...
