Also, the advanced G-code extensions in LinuxCNC allow you to program this with some variables and sin functions.

[Emc-users] following error only while homing
Why would I get a following error only while homing (latest Linuxcnc 2.7.9)? I
recently added home switches to my machine. My machine has encoders on the
steppers on each of the 3 axes so I want to use the index pulse for home. I
set up the homing sequence each axis and when I do "Home All" I get a
following error on my Z axis (first one to home). I played with all the
settings and can’t get it to complete unless I set ferror and min_ferror very
high Also, once there is a following error I can only clear it by exiting
Linuxcnc and restarting it. If I just turn it back on, it immediately faults
again with the same following error. If I don’t home, after restarting
Linuxcnc, I can run the Z axis (and X and Y) all day at any speed without a
following error.
I have tried setting the ferror and min_ferror settings to various reasonable
values but it didn’t work. Before adding the switches I had error=0.001 and
min_ferror=0.0005 and never had a following error appear. I set ferror to 2
and min_ferror to 1 (I think those were the values) and it worked but then got
the following error on the Y axis (the second axis homed). The values for
ferror and min_ferror that “worked” seem completely unreasonable given I am not
even moving anywhere near my max velocity during homing.
I have tried changing the sign on the HOME_LATCH_VEL to make it search for
index in the other direction but the same thing happens. Below are my
(current) machine hal and ini.

Re: [Emc-users] Things are quiet
So you want to use polar coordinates? That is very easy with LinuxCNC, just use the @ symbol to specify the length and angle of the path. Ex: G1 @1^10 creates a line segment with length 1 at an angle of 10 deg from the x axis. See the docs here: http://linuxcnc.org/docs/html/gcode/overview.html#_polar_coordinates On Mon, Jun 19, 2017 at 9:51 PM, jim wrote: > I Want to sharpen a band saw mill blade which has a 10 degree tooth angle. > > Will be using a 1/4" Dia. stone in the spindle and following the shape of > the blade. > > Then indexing to the next tooth. > > I will try g15 and g16 even though they are not on the reference list. > > > > > On 17-06-19 09:18 PM, Stuart Stevenson wrote: > >> Yes, it will probably use the same g code you see for other systems >> >> Which 10 degree angle do you want? >> >> >> On Jun 19, 2017 7:29 PM, "jim" wrote: >> >> I need my machine to move On a 10 degree line using the x y axis . >>> >>> I see g codes for this on other systems . >>> >>> Can Linuxcnc do this? >>> >>> Thank you, >>> >>> Jim >>> >>> >>> >>> -- >>> Check out the vibrant tech community on one of the world's most >>> engaging tech sites, Slashdot.org! http://sdm.link/slashdot >>> ___ >>> Emc-users mailing list >>> Emc-users@lists.sourceforge.net >>> https://lists.sourceforge.net/lists/listinfo/emc-users >>> >>> >> -- >> Check out the vibrant tech community on one of the world's most >> engaging tech sites, Slashdot.org! http://sdm.link/slashdot >> ___ >> Emc-users mailing list >> Emc-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/emc-users >> >> > > > -- > Check out the vibrant tech community on one of the world's most > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > ___ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Things are quiet
I Want to sharpen a band saw mill blade which has a 10 degree tooth angle. Will be using a 1/4" Dia. stone in the spindle and following the shape of the blade. Then indexing to the next tooth. I will try g15 and g16 even though they are not on the reference list.

I was thinking the same thing. It's very unusual for this list to be so quiet.
