Re: Choppy motion - VCarve?

Set it on Precision Router and cut some test parts to check for accuracy and possible rounded corners. Mine are always spot on, but the faster you feed, the more chance of rounding there might be on sharp corners (below 90º). Gotcha, will do. Thanks for the tip. I'll read through the manual on it.....

Re: Choppy motion - VCarve?

Yep, that's what Exact Stop does. Your file on my machine with Exact Stop runs terribly jerky/rough. On my table router, I always run Precision Router, along with a couple of custom smoothing presets for 3D relief and V-carve. See sections 12.22 and 12.23 in the manual for some definition. Strange ...

Re: Choppy motion - VCarve?

Hi All, So I turned on smoothing to "Precision Router", and holy cow, what a difference. Like night and day. So I wrote a simple circle code, no nonsense. I posted it below. That same code comes out choppy on exact stop, and smooth with smoothing turned on. I was trying to eliminate the po...

Re: Choppy motion - VCarve?

If you saved both files with the same post, then that post is putting out arcs. You can check by opening the pp and looking to see if it has the variables for arcs and also the begin arc statements. If you bring a .dxf into VCarve from another program, it can be segmented. Sometimes a circle or arc...

Re: Choppy motion - VCarve?

I'll check on that when I have a minute to fire up the machine.

Re: Choppy motion - VCarve?

What PP are you using in Vectric? The file of yours that Keith opened and shared is using all G1 moves for circles and this is not correct. Can you share the actual Vcarve file so I can open it in my software and use my PP? Change the name just like you did for your motor files. You should be using...

Re: Choppy motion - VCarve?

thanks for photos. can you take covers off of servo motor area? is there any gear reduction from the axis motors to the rack pinion? Adding some photos with the covers off momentarily - I'll add them to the previous link. There is gear reduction between the servo and the pinion gear, and the two ar...

Re: Choppy motion - VCarve?

I am, however, leaning more and more toward a motor tuning issue. You mentioned the motors were tuned by Tecknic. Did they do it on your machine? Thanks. They did. It was a bit of a dance, I needed two separate computers - 1 hooked to each X axis motor - so they could monitor both simultaneously.
