Mauri,
Sorry for my English.
I installed 1500, as you advised - the circles are not even.
I started the old wizard. Make sure that the CV mode is on. Set the speed to 500. The wizard counted the speed. I restarted Mach4. The circles are not even.
I have a machine for cutting metal with a laser (1500 W). http://forum.machsupport.com/forum/index.php/topic,35121.msg241204.html#msg241204
Backlash compensation I do not use. I do not use a reduction. Motors are attached to the toothed rack Gudel.
Tell us what additional information is needed.

SEREGIUS,
Not sure what is going on.
I know Mach4 is not the issue as it works near perfect on our Mill with HiCON when making a circle.
I am waiting for ESS Backlash before I use my Router Table with Mach4.
If I have time, I will do a test on that Machine.
I need to fully set it up first.
Regards,
Mauri.

What is the maximum speed on this machine?
Tested Mach4 at speeds of 20,000 mm / sec and higher?
I need to cut the metal at a speed not lower than 25000 mm / sec.
I will try to set the speed in the gcode 20000, 10000, 1000. And see the changes.

Just an observation but I assume we are talking about speeds of mm / min. and not mm / sec.

Tweakie.
KEEP SAFE !

Excuse me. Yes, mm. Thank Tweakie.

Hi,
I conducted cutting tests at different speeds.
26 000 mm / min - the incision is not round.
16000 mm / min - the incision is not round.
6000 mm / min - good lap.
The speed changed in the file GCode.
The speed of the CV set to 500. The braking is not visible, as if mode CV is not on. Squares and rectangles are cut well. If mode CV is turned off, the squares are cut badly. So mode CV is on and does not work on arcs.

SEREGIUS,
Try doing it with X/Y for the Circle in G-Code instead of I/J and see if it comes out correctly.
Regards,
Mauri.

Mach4 reports an error.

SEREGIUS,
You have to program the Circles to use X/Y not just transpose them.
I have run your G-Code under simulation and the Cut Path follows the G-Code Circle.
Have you checked that your X/Y that your Steps per MM in the Mach4 are correct by measuring distance traveled with a Slip Gauge and a good dial indicator?
I think this is your issue and not the Mach4 program.
Below are two examples 2 circle 1 is 100mm diameter and the other is 120mm.
100-120.txt is the X/Y circle cut.
100-120Arcs.txt is the I/J circle cut.
Regards,
Mauri.

I use Camduct 2018, i can not get to write the gcode of the circle G1. Only G2 / G3.

At what speed? At speeds up to 10,000 mm / min, a good circle.

Yes. http://forum.machsupport.com/forum/index.php?action=dlattach;topic=37691.0;attach=49161;image How accurate should the setting be? 0.01 is enough? 0,001?

Maybe...
But Mauri, I can not understand the following questions:
1. On this table, Mak3 cuts well. All circles.
2. Mach4 cuts well, when the arc is defined by one line.

3. Mach4 cuts badly when a circle is set by two dvigami.

4. You tested mach4 at speeds above 10 000 mm / min, to say that mac4 works without errors?
5. Why does Mach3 cut well, and Mach4 is bad (on the same machine), but you say that I have a problem, but not Mach4?
I can't cut the code you gave right now. I do not have axis Z and A. I need to edit it.
