4 axis machining problems

[adidoro]

I was trying yesterday first 4 axis machining and things goes wrong, I checked the g-code online and it looks good there. Please see attached photo and g-code file.
Link where I checked the g-code is https://ncviewer.com/
I have MK1 controller from 2011 and never tested it on true 4 axis machining.
Also X Y and Z colors are wrong in software, and the tool path is reversed on Y axis that is my rotary axis on.

And should be like this:

Apart from G40.1 g-code (which is used for C axes on some Fanucs) .and incorrect toolchange in beginning I don't see anything wrong. NCviewer displays this incorrectly

I removed what was wrong for you, the problem is the deviation from the tool path marked in red on the picture, I ran this code and it broke my part exactly as it looks in CNC USB Controller, but in NCViewer tool path it is exactly as it should be. I have attached the modified tool path to check it.
Second, in all CAM CAD programs the X axis is red and the Y axis is green.
Third, the tool path does not look the same in the nc viewer with CNC USB Controller as an orientation.

Found the problem, B axis in machine definition was on Y+, changed that to Y- as it is on my machine placed, tool path is good, orientation also good, but god still X axis must be RED and Y axis GREEN.

Axes colors are "standard".

Exactly as I said X RED and Y GREEN, in CNC USB Controller software the X is green and Y red as you can see in pictures bellow.

Seems that old software used these color. I never noticed they are not correct.
Why don't you use TNG?

[adidoro]

Because I have a DIY Controller MK1

How the hell I do that, I have the same problem with TNG now.

I think is only a display problem related to this https://www.cnczone.com/forums/plane...y-problem.html
Waiting for an answer and a solution to that thread to compare, I don`t have nerve to run that program on my cnc.

Seems like you don't have correct orientation.

I already know that, please check this thread https://www.cnczone.com/forums/plane...y-problem.html

Good morning, could you tell me what post processor you use to perform 4-axis machining, I also have a mk1 and I use USB CNC. I use Aspire but I don't know what is a suitable post processor.

Good morning, could you tell me what post processor you use to perform 4-axis machining, I also have a mk1 and I use USB CNC. I use Aspire but I don't know what is a suitable post processor.

Here is the post processor that I have used in Aspire with MK1, if you have rotary axis on X open file with notepad and change ROTARY_WRAP_X = B to ROTARY_WRAP_X = A and then save it.
I hope this help.
