Hey all, I'm sort of new to this,

Hey all, I’m sort of new to this, so please forgive me if this problem has been solved. i’ve been looking but haven’t found it posted.

i’m having a problem with drill sizes being milled out with the eagle brd importer. simple put here is a picture of what the board was supposed to be milled out as; (screen shot of chillipeppr’s render) but ended up as (picture of pcb)…

everything was working fine, then none of the boards wholes were getting milled right. so i made a little test board (which is what this is). I dont remember change changing either setting or any step of the process from when it was working. i’m including the gcode. thank you in advance so much for your help. i’m guessing it’s probably just a newbie error… thanx for your time.

Under Gcode Tab, Drilling Tab change the field titled “Maximum hole diameter to drill” to the size of your largest drill bit, any holes with diameter larger than this value will be milled by cutting tool, so you need to change the tool before you proceed.
The gcode you shared look normal, milling paths are generated for any holes larger than 1mm which the default.

clinton_r · February 4, 2018, 11:06pm

@ameen.nihad thank you for getting back to me. i believe that is how it is set. the holes for the anderson power poles are about 5mm so it should have definitely milled them. is it possible i messed up some arc setting or something?

i just tried it again. this time taping a marker and transparency instead of wasting more fr4. i noticed that even the if you follow along on the screen it doesn’t mill the circles. so i captured the screen (“4” link included in the post) and before hitting play i scroll thru the settings. p.s., since the drilling part works just fine i created another text brd and including the gcode created for it.

Can you share the eagle file you used in the video?
The first gcode you posted should work fine but the second one is definitely wrong, once you share the .brd file I will try to reproduce the issue and see what’s causing it.

clinton_r · February 5, 2018, 9:22am

@ameen.nihad no problem. here is the one from the video. tonight i’ll also do a ‘sharpi run thru’ with a board that i’m actually trying to make. not sure if it’s related but about the same time i started having this issue i started having issues with the widget not acknowledging polygons. i read tho all the posts that i could find and went back and double checked and everything named right, and dimensions are there etc. and yet when a trace enters a poligon the widget will litterally outline only the trace with an abrupt end where it would otherwise enter polygon. everything seemed to be working fine then all of a suden. tho i have yet to go back and see if someone of my old designs that did work are now in the same boat. i will do that tonight as well… in the meantime here’s the link to the brd file i used in the video. i should note that i specifically chose components with holes larger than 1mm, and even included a large round pad as i was going to see what happened if i used the solder mask component (had an idea that maybe the tiny g is having issues with arcs or something)

thank you sooo much again, not only for ur help but also ur hard and really awesome contribution

ameen.nihad · February 5, 2018, 4:35pm

There is something wrong with G3 commands generated by the widget when the command is for full circle! It used to work fine, apparently a recent update related to GRBL is causing this issue, as a quick workaround you can delete XY values from any G3 command and leave only JI values, like this:
G3 X10.64 Y18.93 I0.5000
G3 I0.5000

G3/G4 are a bit difficult for me to understand and remember, I’ll try to find a solution after doing some research, to make sure the solution will work with all supported controllers.

clinton_r · February 10, 2018, 11:21pm

@ameen.nihad do u have any recommendations for a simple gcode editor (preferrably for mac) … i’m trying to do it in textedit and even with fine-replace it’s driving me mac. lol

ameen.nihad · February 11, 2018, 8:06pm

I also use text editor, I don’t know if there is a gcode editor!
@jlauer from Eagle widget is there a way to check if we are generating gcode for tinyg or grbl?

jlauer · February 11, 2018, 11:34pm

@ameen.nihad I suppose the best way is just inspect the URL like window.location in Javascript.

ameen.nihad · February 12, 2018, 6:33am

I made a quick fix for this issue, G3 for milling hole will be generated as in the following examples:

on grbl or jpadie workspaces:
G3 X16.01 Y20.32 I0.5000

any other workspaces:
G3 I0.5000

@clinton_r this should solve your issue.

clinton_r · February 15, 2018, 3:37am

@ameen.nihad thank you soo much… for the fix as well as a great widget.
