BOXFORD 125 TLC Tool changer LINUXCNC

[Clive S]

Hi Clive. Thanks!

I didn’t change anything, coz frankly...I don’t understand it(willing to learn).
I include all files in zip here. including untouched config. So anybody, or maybe even you can give it a try. It’s simple stepconf 2 axis lathe without feedback/inputs, so it will run without machine.

I’ll appreciate any the help.

Ok first. Have you actually got the lathe running under Lcnc? if not then start by getting the X and Z working first. then get to the tool changer later.

Do you have homing working?

[garulus]

Yes and no. I already have my mill up and running under linuxcnc, so I know what I’m doing with stepconfig. My lathe is just X Z steppers on the table + toolchanger. No home/limit yet. It is easier to test on PC without any inputs(homing manually in linuxcnc). All I need to know is how to implement this tool change component.

Update:

I copied file toolchanger.comp to my linuxcnc/configs/Lathe folder

Then copied Header:

################################################## #######
# .ini file for axis - ATC set up as axis A angular
################################################## #######
[AXIS_3]
...

to the end of my Lathe.ini file

Then I copied:

################################################## ########
# example Hal linkages required:-
################################################## ########

setp stepgen.3.position-scale [AXIS_3]SCALE
...

AND

################################################## #########
# loading the toolchange component in .hal file
################################################## #########

loadrt toolchanger
addf toolchanger servo-thread
...

In to my Lathe.hal file

Then I run terinal in my configs directory to compile:

sudo halcompile --install toolchanger.comp

(sudo comp --install toolchanger.comp) don’t work!

Still stuck Here when try to run linuxcnc

/Lathe_Orac.hal:87: parameter or pin ‘stepgen.3.positio-scale’ not found

When you use stepconfig it will overwrite any changes you have made. so it is best to not use it and hand edit the files after the first time setup.

I have noticed that here:-
[TRAJ]
AXES = 3
COORDINATES = X Z

you might need to make it COORDINATES = X Z A

Hi. I know that stepconfig it will overwrite any changes, but before I make final setup I need to know that I’ll be able to implement this toolchanger component. Keeping it simple for now.

COORDINATES = X Z A(B,C) don’t work. Still same error message: /Lathe_Orac.hal:87: parameter or pin ‘stepgen.3.positio-scale’ not found

It would be nice if anybody who understand linuxcnc will try to implement it, and share results/knowledge. It’s time to make good deed...to please north pole for upcoming x-mass 2019

Well there are more people on the linuxcnc forum that do understand it. But are you sure that the error message that you have put up on here and the linuxcnc site is correct. /Lathe_Orac.hal:87: parameter or pin ‘stepgen.3.positio-scale’ not found

Hopefully someone will try it and will help. And you don’t worry anymore. I appreciate your effort.

Ok but that is a different error in the screen shot as the spelling is different.
