Hi David,

Thanks very much for your help. Greatly appreciated. I will investigate these two ideas, I'm sure you will be spot on.

Hello

Welcome to the forum

When you get "crop circle" in Mach3 display, this can be related to two problems.

1) The arc center mode selected in CamBam is not the same that the one selected in Mach3 ; to solve that you must select a Mach3 post processor to produce your GCode ; the post processor contain the commands that will set the Mach3 arc mode to match the one used in CamBam. (to Match CamBam settings, in Mach3 you can also set this arc mode manually in general config, "Distance mode" must be set to "absolute" and "IJ mode" to "Inc")

2) depending if you're using Inches or mm two settings must be accorded to the units that are used. By default the values in Mach3 post processor are set for Inch users and are to small for mm users. (Minimum Arc Length and Maximum Arc Radius)

How to's and tutorials / Post processor inserting G3 and G2

« on: July 02, 2022, 05:02:13 am »

HI I am relatively new to CamBam and I am having problems with the post processor.
When I load the Gcode on Mach3 Plasma the visual display on mach3 shows lots of large circles which indicates to me that a G2 has been transposed for a G3 and vice versa.
I must be missing something in the post processor set up.
I can edit the g code and replace G2 or G3 with G1
Any advise would be greatly appreciated.
Thanks
John
