Aspire has an option to simplify the vectors you are intending to cut. I think it is called "smooth" or some such. you can change the setting in that option to make the number of line segments less. Gives you machine a much easier time. You will hear the difference from the sound of the axis motors.
Thanks for the thoughts. All very helpful.
I'm amazed that i've not found this to be a major issue before? The machine was built for one purpose which its managed very well, running for several thousand hours quite happily. I did a basic setup when I built the machine but not much fine tuning. Its a belt drive running directly of a 15T sprocket. Still i've always wondered why it cut radius (none critical) in an odd way sometimes. looks like this combination of feed, velocity and acceleration is critical.
You suggest increase acceleration in motor tuning, as 100 is quite low. What would be your suggestion there?
Based upon your advice to lower velocity and increase acceleration whats your guess for a decent feed speed?
Thanks for all advice.
Thanks for the Aspire info. i shall seek out "smooth" and amend.
I have had this with small jobs too, the finish looked very rough and the machine was very jerky at higher speeds. With the smoothing, because you are actually telling the machine to do circular sector, it interpolates intrinsically and is just so much smoother.
I'm just in Aspire now and using the 'S' fit curves to selected vectors tool. I can see the difference in file size immediately. I just need to remember to tick the 'replace selected vector' box otherwise end up with two files on top of each other.
I see a 'T' tool in vectror curves section of Aspire which is convert objects to curves. Similar or not, or for another day I wonder?
That is for converting text fonts into curves so you can profile them or edit them like vectors.
