Title: Different speed with the same code [Print This Page] Author: stivemaster Time: 2019-3-23 03:48 Title: Different speed with the same code First I want to thank for the help. I changed the software version from 89 to 106. At the new version there is a difference in the logic of PWM and M3 and a bit difficult to understand the logic, but I get it right. Probe is already working and this video shows the result of it . There is, however, a strange problem. The controller changes the speed of two separate files in which a part of the code is the same. This is the code with which I cut, I just copied the same code and the speed is visibly different.
What can be attributed to this?

Congratulations on solving the probe problem.
Can you describe this speed difference problem in more detail? It is best to provide the relevant g code and configuration.Author: stivemaster Time: 2019-3-23 15:43
Well the problem is visible in the video that I have given. First, the machine cuts the profile and this is a separate file because it may have to be done at the beginning of each profile. Then I run a second file that makes two opposite holes and the same cut off. For the second cut, I just copied the code from the first file. The speed is visibly different.Author: ytliu Time: 2019-3-23 20:49
I can't make accurate judgments about the information you provide. You can check the following items:
1. The speed of G0 is determined by the #80 parameter, not the F programming word;
2. The #125 parameter can affect the speed of G2/G3, such as F=1000mm/min, #125=0.5, then the speed of G2/G3 is F*#125=500mm/min;Author: stivemaster Time: 2019-3-23 23:16
The Y,Z and A movement of the cut is only with G1.Author: stivemaster Time: 2019-3-25 23:26 Last edited by stivemaster In 2019-3-26 00:02 Editor
This forum obviously does not answer all questions.However, I will try again and upload the problem files.
When running file 21, the speed of movement on Y, Z and A is greater than when the file 22 is released. I wonder why this happens?
Additionally, the problem is not only with the speed set by the F and G00 speed and it performs many times at high speed.

How is your #6 parameter set? If the #6 parameter is not equal to 3, the system will automatically optimize the speed, you can configure it to 3, turn off the speed optimization function.Author: stivemaster Time: 2019-3-27 00:15 Last edited by stivemaster In 2019-3-27 00:34 Editor
What does this parameter mean and where does the manually talk about it?
And I could not understand why G02 and G03 are running at half speed ?

Do you mean that axis that is rotating should I set it as linear?Author: ytliu Time: 2019-3-27 17:33
You can set the #6 parameter to 3 to turn off the rotary axis speed optimization function.Author: stivemaster Time: 2019-3-28 02:01
In my opinion, there is no noticeable difference.
Question:
How ahead in the code looks at the interpreter? And how to speed up successive G1 movements?
