@whimsycwd David Charlotte at Vectric Support, after reviewing the GCode files you provided and a couple I had generated, recommended that I try using the Grbl (mm) post processor file. She recommended that I test this post processor first, and review the GCode before loading it to cut to make sure it all looks correct.
I have used Aspire to generated a set of GCode files which I am testing.
@whimsycwd David I wanted to give you an update on where I am on working on using Vetric LTD’s Aspire (http://www.vectric.com/products/aspire.html) to generate G-Code files for use by SnapMaker CNC Module.
As I had previously reported Charlotte Pullen, Tech Support, Vetric LTD, after reviewing the sample G-Code files that were provided had recommended I generated a G-Code file using the ASpire 9 Post Processor listed as Grbl (mm).
I used Aspire 9 to create an 80mm x 80mm engraving to run on the SnapMaker by importing a JPEG of my family crests and converting the B&W image into a 3D model with both roughing and finishing tool paths.
While only used a single spiral straight bit for the entire project Aspire wanted to create 4 tool paths and instead of fighting the software I saved the G-Code as a roughing file and a finish file.
SnapMaker requires that the G-Code files have a file extension of .nc for the CNC controller to recognize them so I rename the files to 3D Roughingl - Copy.nc and 3D Finishing - Copy.nc.
To execute the files I chose to use the Windows based Snapmakerjs-2.2.2-win-x64.exe program instead of the standalone LCD controller/SD mode so I would have the ability position the tool piece and abort execution if something happened.
Loading the G-Code into Snapmakerjs-2.2.2-win-x64.exe and 3D Roughing - Copy.nc went as I expected. I have include a picture of the work piece at the end of the run.
Execution of 3D Finishing - Copy.nc also went without any real surprises other than the finished workpiece had the same level of detail as at the end of the roughing pass. I suspect this is more a statement about my lack of proficiency at converting a picture to a 3D model in Aspire than the SnapMake to execute G-Code generated by Aspire.
I need to work on refining the image to sharpen the image and the tool paths. Looking at the roughing toolpath simulation in Aspire the carving I ended up is fairly close match.
