How to config WorkArea about bcnc

[chamnit]

I think it's based on the machine coordinate system and G92 offsets. Once you set part zero within the machine volume, the g-code paths should be inside the yellow box.

I don't use G92 for anything. In this example I used G55 WCS. After selecting G55 there was no change to the work area. My gcode paths are still outside the area.

@Scott216 working area is displayed based on some settings in Configuration file the fields are named travel_x, travel_y and travel_z
The problem is that for some reason the values are read in the opposite direction. So to have a try you can add a minus in front of the actual values. It seems also that the minus sign must be immediately after the equal symbol or will not be read correctly.
I suspect @vlachoudis will fix this in a couple of nano seconds.

Have a look at https://github.com/vlachoudis/bCNC/wiki/Configuration on how reach the file based on your OS.

I'll give that a try.

@effer the numbers are used as negative to describe the workarea, because this is what I was getting out from the grbl. Looking at the (thread)[https://github.com/grbl/grbl/issues/678] this is the default behavior of grbl. However @Scott216 after zeroing the G55 workspace it should come out right?

[HomineLudens]

That have a sense. Now I remeber that by tradition the coordinate system is referenced from top right corner. And at beginning was also the choice for my cnc. I will write some clarification in the wiki with a picture.

@Scott216 could you please confirm that by zeroing the WCS G55-G59 the workarea goes to the right place. If not then there is a bug somewhere :) which I need to find out.

[Scott216]

It will have to wait until next week.

I just did a little test with the work area. I use G56 for my work coordinates and loaded in a gcode file. The work area is way too big, about 60 x 60 inches. In the CNC section of the ini file i have about 11 x 13 inches. The work area is oriented properly. I'm using v 0.4.5

[vlachoudis]

@Scott216 I forgot the correction of the workarea that @effer made. It should be corrected now

[Scott216]

WorkArea seems okay now. It's the right size and position

[vlachoudis]

Perfect :)
