great. now i would try a different PC. run the PC tuner on it and simply copy the CNCM directory from the existing PC to the new one (no need to reinstall v5.1) and run your test file again. if problem still exists, they evidence is pointing more and more to motor/drive related issues (not tuned pr...

I ran your G-code on my machine. Without smoothing on my machine got up to about 250 ipm. With smoothing on using a custom profile that I use most of the time I got up to 395 ipm. It is a small circle and my clearpath motors RAS setting of 99ms may affect that as well. Bill Thanks for testing that ...

I'll see if I can find different PC (I don't have another one), but this one is relatively new and seems to be well equipped to run CNC12. Can you think of any setting that I have wrong in CNC12? Before I go buy a new PC, do you know why an unfit PC would cause this problem? I have the Leadshine Hyb...

Hi Keith,

Okay I just finished the painstaking process of installing the latest version of CNC12.

I ran the G Code program again, and it does the same.

See attached gcode, report, and Video

g code smoothing is not [to] be used with full size lines and arcs. Thanks for the response Keith! Gear reducers are on their way. However, as you mentioned, I should not have to use g code smoothing for simple lines and arcs. As in the previous video, for some reason, the system can't handle these...

Not seeing any tiny .002" moves... Unless I don't understand how these arc moves work.

Keith any ideas on this?

Your router is not running in the recommended turns/inch range and the motors are vibrating at low speed. Smoothing is not the right medicine to cure this ;) At least add gearing to bring it in the recommended sweet spot, this will also avoid the slow vibrating speed of the motors. Uwe Yeah just or...

[/quote] post the g code program. the last one had very very short moves, so short that it was beyond necessary. adjust the minimum vector length in the cad/cam system so it doesn't put out .002" moves :D [/quote] Heres the relevant code for the circle: (2D Contour9 (6)) N240 G0 X-4.0125 Y8.950...

no need to have smoothing ON with this type of g code. smoothing is for short vector g code. not G2's/g3's see this for more info. https://www.centroidcnc.com/centroid_diy/downloads/acorn_documentation/acorn_gcode_smoothing_users_manual.pdf fyi..smoothing Will NOT make up for bad gearing or other m...

Not sure if this changes anything, but I learned that these are not servos, they are “hybrid steppers/servos”, which is just a stepper with an encoder.
