Hi all,
a newbie here: just finish my first cnc router... happy, but...  
I can jog (manual) with no issue. but then when I run a simple gcode, I found this idle issue. I noticed the cnc idle for couple seconds when running the G2 or G3 code.
I did search in google but no luck for the clue/answer.

my cnc router configuration is: PC (WinXP) -> Mach3 -> Ethernet SmoothStepper (ESS) -> Gecko G540 (-> Super PID for Bosch spindle).
I run Mach3 and toolpath in Metric unit.

Mach3 latest version.
I am using ESS_v10p1d1g.m3p for the Ethernet SmoothStepper plugin since this is the one that could run slave homing (I am using 1 homing switch and 2 lead screws/stepper motors for Y stage).

Here I attached the xml I have and screenshoot on the Mach3 ESS general config and my PC's specs.

I really appreciate for any help or feedback.

thank you!

Correction: my bad, the pause/idle for couple seconds happen on every next gcode line, not just specific G2 or G3, but any next line.

can anyone help? maybe a hint?

bump...

please help...
anyone? nobody?

Can you attach the code, also if possible can you shoot a vid and upload to youtube.
Might also be worthwhile looking at the CPU load whilst running the code to see if there is an issue there.

hi Hood,

I am glad you are stopping by.

here is the video: https://www.youtube.com/watch?v=M_mMO8OCd4o&feature=youtu.be
and here I attached the code I was running.

fyi, the video is using a relatively new PC... which should be powerful enough in term of processor, memory and video card. I haven't put the license file as I want to compare if the 'demo' and the 'license' would make a different, and the answer is no.
I noticed this powerful enough PC's motherboard doesn't have parallel port.

additional info: I am using VC mode and disable backlash.

if you noticed on the video, there were few times the feedrate showing a very slow speed but then something goes very high speed (frame 1:42), which I just noticed when I watch this video.

please let me know any other (the right) question to inform you the detail.

Go to Settings page and turn off Tangential Control.

hi Hood,

you the man!
it is running smooth now.

I wonder what 'Tangential Control' is. Will read about this feature tonight with happy face.

Thanks a lot!
