Did someone say bugs?!

I have this thought back before my table existed and before I knew Plasmac existed. I think it's about the only thing that Plasmac doesnt do by default that I had on my "wish list" back then. Now that I have my table I'm not entirely sure it's strictly necessary, but it's fun to think about anyways.

I assume you're using a G10 rotation?

Yes, its a (significant) variant of John Thornton's work.
The Maths really did my head in and then I had to convert it to gcode which was even worse.
There are 3 macros. Start_align, Align-X and Align_Y. So you click on start _align and then when on the corner, you pick if you are aligning along the X or Y axis. I hoped this could be folded into one button which worked out the correct axis you were using.

I have not found a need for it but I think someone like Stefan who drops a full sheet of 16mm on his table might appreciate it.

how can i load 3 pwmgen
i have 7i92 which have firmware with 2 pwmgen
where can i find 7i92 firmware with 3 pwmgen

Peter (PCW) will probably come along if he sees it and if you are lucky he just might build you one.

On another note I have read and re read this post many times and I am very interested. I think you said somewhere that you might release the configs files etc

What pinout do you need?

sure i will in my github...
after finish the basic functionality

i will use 2 Chinese BOB with it..

so p17 on p1 and p2
3rd one any pin on P2

3 axis + foucs = 4 joints

7I92 config for 2x "5 Axis Mach BOB"

Normal spindle PWMs on pin 1s

B axis step/dir on pins 16/17 replaced with PWMs
So 4 Step/Dir axis per BOB 2x 5V accessible PWM per BOB

whats the use of VHD file
and can i use PNconfig?
where can i place those files what direcly in linuxcnc

The VHD file is in case you want to make a changes in the firmware later
You can use pncconfig but it will not know about the PWM gens
so you would need to edit the hal file to set them up and connect them to
the desired LinuxCNC pins
