Is any else having problems with 1.70. I uploaded 1.70 the other day and and when I went to carve the spindle just slowly lowered and started to cut but at a very very low feed rate. I validated all the setting for my endmill and it just would not cut properly. I downloaded the g-code and then downloaded V1.69 and ran it and it carved properly. When I was done I downloaded the g code for V1.69 and ran both of them through AI and it found significant differences (hundreds of lines were different. Here are the g codes.
@LarryLSimmons I know nothing about Carveco, but you don’t need AI to tell you that those files are not near the same, especially the Y moves and the feed rates.
Yes I used the same processor for both 1.69 and 1.70. I really don’t know enough about g code to see the problems that’s why I use AI, plus I asked it to identify which lines were different. I sent both of the files to Carveco support.
@LarryLSimmons Pls post the reply from Carveco. The differences in the gcode files make no sense at all. It’s like the gcode files were created from 2 totally different toolpaths.
Thank you for your enquiry and for providing the G-code files generated using Carveco versions 1.69 and 1.70.
Having compared the two files, we can see some significant differences in the machining parameters, particularly the plunge feed rate, which is set to 30 inches/minute in the 1.69 file but just 0.8 inches/minute in the 1.70 file.
This could explain the extremely slow movement you experienced when attempting to machine using the toolpaths generated in version 1.70.
To help us investigate why these differences have occurred, please could you confirm/provide the following:
Model file: Please provide a copy of the original Carveco model file containing the toolpaths used to generate the supplied G-code files.
Post processor: Which post processor (machine file format) did you select when exporting the toolpaths? Was the same post processor used in both versions?
CNC machine: What is the make and model of your CNC machine, and which machine controller or control software are you using?
Toolpath settings: Were the same model, cutting tools and toolpath settings used in both versions? In particular, were the toolpaths recalculated after switching between versions 1.69 and 1.70?
Exported files: Can you confirm whether the two G-code files supplied are the original, unmodified exports from Carveco, or whether any additional toolpaths or G-code have been combined into either file?
@LarryLSimmons I’m not surprised by their reply. They seem to be as confounded as I am. The differences in the two files make no sense. Thank you for posting this. Please post their final solution after you have sent them what they are asking for.
In the 1.69 version they are all pockets with a zig zag ramp down to a single pass.
In the 1.70 version the first circular shape, from the left, is above the pocket like a rapid move and the rest are at the bottom of the pocket. Also, the stepover seems about twice as big.
I may have sent that wrong 170 file. I found the problem when I was trying to cut out the pockets that you see in both. not sure why those other tool paths are in that file as they were not part of the model.
There may have been an issue when I was trying to copy the 170 g code as my problem was with the pockets.
Not sure what happened but I ran 1.69 again and downloaded the g code and then downloaded 1.70 again and also downloaded the g code. I ran a comparison between the two and now they are identical.
I don’t know what caused the initial failure, but it seems to have been resolved.
