Chinese cnc plasma, help with finding post processor

Hi, I have a Chinese plasma cutter. I use the software called hycam that came with it. I have to design the parts in Fusion 360 and use the included software to make cam, would like to use Fusion 360 to do both cad and cam but I can't find a post processor that will work with the cnc, did  a search on google and on this forum but didn't find a match, need help to find one or modify the config of an existing post processor. 

 

all the help will be appreciated.

 

uploaded the gcode and part with some additional info.

 

the gcode file has to be saved to a usb drive and opened in the cnc 

gcode with file extension .CNC

kerf of 2.5

I have a post nearly modified to match your sample. I have a couple questions.

 

1) How should comments be formatted? Leading semicolon? Square brackets?

 

2) Your sample is using G91 incremental with a G92 location reset. Are you required to use this method or can the post be G90 absolute?

Hi, thank you for taking the time to respond my post, for your questions, I realy don´t know if it uses  leading semicolon or square brackets, how can i find out?

For your second question it does need the the G91 and the G92 reset. All the post process g codes I have made  havethe G91 G92X0Y0. I uploaded a pdf file with the g codes this cnc uses. Hope this help.

 

thank you for your time

From the manual:
G92 Reference Point Setting
Before running program, setting work start point coordinate value in the program beginning and use absolute coordinate setting.

 

My interpretation is that "G92 X0 Y0" sets the current XY position as zero and uses absolute positioning, effectively negating the preceding incremental positioning, but when I back plotted your sample code, it definitely was incremental. Absolute vs incremental is a function of the back plotter. Not sure why Hycam uses incremental unless it's enabled someplace. The default for the control is absolute.

 

The attached post is using absolute positioning.

 

The G92 command is hard coded to XY zero. You can disable this command in the Post Process Program Setting by changing zeroTorch=false.

 

All comments are disabled by default because I don't know the format used. All G and M codes use 2 digit, example M07 or M08.

 

Try this post and let me know how it goes. You set your kerf width based on the tool library the attached file has a 2.5mm sample. Make sure when you setup your cut paths that you select in computer compensation on the passes tab. Also, when you select your geometry you can toggle inside/outside by clicking on the red arrows.

Hi Randy, been making designs and post processing them and the post works great, just one question how could you make the torch go back to the origin after it finishes?

thank you very much for your help really appreciate taking the time.

Glad your up and working. Some machines have an M code to end the program and return to the clear point. In your case I hard coded a return to XY zero.

 

Change line 439 to this:

writeBlock(gMotionModal.format(0) + " X0.0 Y0.0");

I've attached the modified post.

Hello Randy, my name is Bob and i to have a china built cnc plasma machine, for about 7 yrs now and it came with IBE cnc cut program that makes Gcode ! It works good , for me , but it worries me that it has to use a dongle before it works , and I am afraid if the dongle messes up in time I will be with out !! I cant speak to the chinese outfit i purchased from, they have no desire to help, never have!! Spoke to the German IBE people and they say , buy a new license !!! That's not fair ! I purchased it for my life, not the dongle!!lol Any thoughts if I can use another program for my machine?? Thanks, Bob in Illinois

@bob  your best bet would be to share a program that you have successfully run on your machine. Don't copy/paste the text, but actually share the file. You will likely need to put it in a .zip file and then attach it

Bob; You are asking if there is another program you can use to program your Chinese CNC plasma cutter. The answer is "yes, Fusion can do this". But, it's not as simple as create a toolpath, generate code. There is a step in between that uses a post processor to generate the code needed. We don't know what your machine wants to see,  and we can't just give you a post processor without know what sort of g-code your controller wants. We could make suggestions, but they'd likely be wrong. So, we need to see a g-code program that you have run with success on your machine.

Now, the problem is, if your code has a file extension that is not allowed on the forums, you can't attach it as a file. So, the answer is to just put it into a .zip folder, as those are allowed for attachment

 

Once we see the code, we can advise you as to what post processor to use to generate a program for your machine, using Fusion 360.
