Fusion
What does this machine use for a controller? While we don't likely have a post processor "ready to go", we can guide you to one that is close and provide some assistance in getting things operational. Do you have any sample g-code for this machine?
Adding 5 axis capability to a post is a relatively easy thing to do.

Hi Seth,
I have the same machine at home but the 3 axis version, it's a small cnc engraver, mainly meant to cut wood, plastic or if you are not on a hurry, aluminum. It runs on mach3 which means doesn't have any RTCP or 5 axis tool comp. Everything has to be handled by the post.

Hi! I managed to get my hands on a postprocessor for this machine, but I have a problem .
I set XY0Z0 at the intersection point of the 4th and 5th axis
I placed my stock of 60x55x95mm and moved the tool on top of it
So I've made this stock on Fusion360 and created a origin point that is 52mm from the top.
I use face operation to make my stock 50x50x95, the orientation and movements of the 4th and 5th axis looks fine but my Z goes too deep into the material
I can see that the postprocessor has a fixed setting "pivotDistance" set to 25mm for reasons I don't know, but if I change it, it changes the Z values.
I have to mention that I do have this f3d and postprocessor from the seller, that I tried and worked fine, or that was my first impression...
What do you think I'm doing wrong?
This may or may not be of help to you, see image below for modelled HY6040 Trunnion and attached Fusion file, used with the 5axismaker PP should work 🙂
Hi,
thank you very much for sharing the post processor. 🙂 I tried to use it on my HY6040 but I have some understanding problems with it.
My machine is configurated in x,y,z and B rotates around x and A rotates around z.
For this I tried to edit the post processor:
I put the wcs at the intersection point of the A and B - axis. Because of this I thought I can neglect the pivotDistance and cAxisOffset. Is that right or for what are these distances?
I tried to test the 3+2 Axis function with the following part:
But if we look now to the g-code i noticed some problems:
The first planing operation should be correct because the block is 50 mm high and wcs is 14 mm away from the bottom so the z value should be 36, which it is:
But at the third operation - the pocket - there is a problem I guess. The block is 30 mm thick and the pocket is 1 mm deep, so the z value should be 14mm, or am I wrong? Here the z is 2.97 and that is to low I think.
With changing of the pivot distance the z value changes. So I think this error is pretty similar to the error @dan3s2020 had with his post processor. But I wasn't able to find a solution by myself.
I would be very thankful for any thoughts or help.
Best regards

Hi Rob,
thank you very much for your response and all your effort, that’s really amazing. 😊
I tried the post processor today and it worked fine for 3 + 2 axis milling, thank you so much, you helped me really a lot.
I also tried a simple 5 axis simultaneous part and at first it didn’t work well. But then I changed the “optimzeMachineAngels2” to one because I have read in the forum that mach 3 doesn’t support TCP.
With that change it worked but the movement sounded and looked not very continues. It seemed like the steps were bigger than usual. Do you know if that can happen because of deactivating TCP-mode or is that normal?
Again thank you very much.
Best greetings
David
