The only issue I can see in the tool path that occurs more regularly but not consistently is the image attached. *The line should be straight but it has some strange triangle mid path.

Ok, I have attached a log with the triangles occurring in the toolpath at the end of the log. I ran different gcode first and tried to reset things as much a possible. I hope this helps. I have also attached a screenshot.

I think we need to know a bit more about your machine. First, do you have encoder feedback? What are you running for electronics. It seems to me like we have a system that is trying to sync with with something that is not in the correct location...

I did look at your posts here and I didn't see a "parts" list for your machine. Could you please tell us a little bit of what your setup is?

Thanks
Brian

Not sure it will help me but I would like to look at a packaged profile.. AND get a Dev version of you are not on the latest code. We had worked on closed loop code and Aux feedback in the latest versions and that may help you out.

Parts list:
I have a converted Optimum BF30 Vario mill converted to 3 axis CNC.
3x Nema 34 12Nm closed loop stepper motor's from steppersonline.
3x 60v power supplies
1x 24v power supply
MB 3 breakout board
ESS
Spindle control via 0-10V Anaspeed circuit on mb3. Using the stock optimum spindle controller.

I think that should be it. Did you want me to add some of my config files?

Did you connect the encoders from the steppers back to the ESS ?

No just to the motor controller. My understanding is that I would need some sort of signal duplicator to do that?

Something very odd is going on and I can't get my finger on it now but ... we will!

Any chance you can tell me what you have for a PC? I wonder if we have some power saving issues .

An Acer laptop with Windows 10. The laptop is plugged in and the fault was occurring approx 5 s into clicking enable, so it is unlikely going into power saving mode so quickly after being active.

I have been thinking about this and I would like to have Trevor log in and check your version of Mach4 and ESS plugin. He can also check the power settings of THC Ethernet port. When would be a good time to have him remote in?
