Hey guys, Brand new to the form but I've been struggling with creating a custom cribbage board for quite some time now. I have a jpeg created for just the holes which are 1/8" black circles but when bring it into the Ipicture program, it doesn't show the holes the same depth and when I run it on the machine, some cut as deep as the max and some not at all. I know it's something simple i'm probably missing but it's driving be bonkers. I've changed the cut depth as much as .4". The settings I have are: Size: 12.8 x 15 x 0.3 Scan Step: default (but I have moved this down to .003937 or .1mm and as high as .4mm to try and speed it up) Tool Type: Endmill 1/8 Feed Depth Per Cycle: Default
First I would say , never run anything on higher (faster) scan step than the default of .2 mm. The reason being, you are putting a huge amount of stress on the motor and the bit by asking them to cut that much material per pass.
When you have a template for the board and run it thru ipicture, any size scaling you do will affect the size of the holes so unless your template is created with some kind of cad program you will not get the right result. Also keep in mind for any projects you create for ipicture to convert that the program "looks" at your image in a magnified way, as much as 3-4 times the size in order to create the tool path. Here is a template I downloaded of the internet: 1 view is normal size and the other is magnified. You will see that the holes in the magnified version are no longer round, and if you look closely you will see that the black within the "holes" is not solid or consistent.
When I did a preview in ipicture, the holes were not the same and even some were triangles instead if round.
In the end I think you would need to make something with a vector graphics program, but I am not sure that would work out either because of scaling your image. Also even though I-Picture supports the following formats of: BMP , GIF , JPG and PNG ....you will get better results in creating any of your projects using the PNG format.
