Hello friends welcome to Free cat
0:01
tutorial and in this tutorial we will
0:04
learn about the path workbench in
0:07
freecad and how to use the path
0:09
workbench for the Machining and create
0:11
the G-Code
0:12
and how to use that gcode in a universal
0:16
G-Code sender so as you can see that I
0:20
have did a simple
0:23
Machining operation for this slot
0:26
using the path workbench and I can show
0:30
you the operation so first I have to
0:33
activate the path workbench
0:36
so I will go here and activate my path
0:39
book page
0:41
and I will say okay
0:44
now here I will go to the simulations
0:49
and I will show you
0:53
that is how material is being removed
0:58
so this is very fast I can decrease my
1:02
speed
1:03
here
1:11
see how tool is moving
1:18
so I will show you from the scratch how
1:20
I did it so first I will delete my all
1:25
this
1:26
path workbench which I have created here
1:29
I will say delete now it is a very
1:32
simple plate
1:34
by 100 by 200
1:37
with the pad thickness of 10
1:41
and here is a cut
1:43
and cut Dimension are here is the R20
1:47
and Center to center it is 100
1:50
so in path workbench
1:53
once you activate the path work which
1:55
you may not see the all the option of a
1:57
path workbench so go here and
2:00
click on the all the tools of a path
2:02
workbench
2:06
so create the Machining operation for
2:08
any part first you have to create a job
2:13
so first I will select on here create a
2:16
job so it will show me the body so here
2:20
is the body one I will say okay
2:23
and here once you activated your job
2:27
then you will see
2:29
stock material
2:32
so it is showing the stock material of
2:34
all the directions x y and z
2:37
one but it is a very simple part for me
2:41
and it is a definitely cut from a sheet
2:45
so this part is not very precise for me
2:48
I just wanted to remove the material to
2:52
fix my bolt so even though surface
2:54
finish is also not important for me so
2:57
it is a very rough cut
2:59
so I do not need this stock material but
3:02
in the case if you are doing the
3:05
Machining operations for any part which
3:08
has the uh fine surface finish like 6.3
3:13
3.2 then you need this stock material
3:16
and you have to create the Machining
3:18
operation for all these faces
3:21
so in this case I do not need any stock
3:23
material so I will make this value 0
3:34
so you can see that now my stock
3:37
material has been removed
3:40
now we will go to the tools option here
3:43
in the tool options we have the default
3:46
tools here so I will go with the default
3:49
tools but if you wanted to
3:53
use the tools you can
3:56
from here you will see in program files
3:59
we get
4:01
mod path and Tool and Tool bit you will
4:04
get here drill End Mill thread cutter
4:06
wall lens but it is the first tutorial
4:09
on a path workbench so I will go with
4:11
default tools
4:16
and then I will keep the rest of the
4:19
values as it is
4:21
and here on the output here is the
4:24
processor so which which is a basically
4:27
machine processor so here I will go for
4:30
the Linux CNC
4:36
and I will
4:38
say okay so here my job has been created
4:42
now once the job has been created we
4:45
will select the our Machining operations
4:47
so here we are going to select this one
4:50
pocket shape so as this is a pocket so
4:53
we will select for the pocket face
4:55
so for that I will select all the faces
4:58
of my pocket
5:02
and I will
5:04
select all faces and all faces has been
5:06
selected so I will select for this
5:09
pocket operation I will say okay
5:11
and now
5:13
here we will go one by one so base
5:16
geometry base geometry is the faces
5:19
which I have selected
5:21
and if you select on these faces the
5:23
faces will be highlighted in the model
5:27
and then for the extensions
5:29
so I'm not going to use any extensions
5:32
here in a depth I will keep additives
5:35
height clearance height or save height I
5:38
am not going to change any things and in
5:40
the operations so in the operations we
5:44
are using the default tools and here cut
5:47
mode is a climb and zigzag so here I
5:50
will select the zigzag if I select
5:53
zigzag then it will remove the material
5:55
with the
5:57
45 degree so let's see that how it works
6:01
in a zigzag so I will say apply and I
6:04
will say okay now you can see the here
6:07
is the path of my tool
6:10
if you click on that it will highlight a
6:12
arrow this means that my tools will move
6:15
in these directions
6:17
so now I will select my job and go for
6:20
the simulations
6:22
and I will play it
6:27
so as we have selected for the zigzag so
6:30
it is removing the material in a zigzag
6:33
format
6:36
so you can see that I'm not very happy
6:38
with this because here it is a
6:41
material stock so we have to select some
6:44
different operations so I will
6:47
I will go to the my job
6:51
and I will go to the operations and I
6:53
will select my pocket ship so instead of
6:56
this zigzag I will go for the offset
7:03
and I will say apply so in offset method
7:08
what will happens this my tools will
7:11
move in these directions
7:17
and then it will go to the middle and
7:19
again it will complete our
7:22
other Machining operations so let's see
7:25
that how it's happens so here I have a
7:28
change it from the offset now I will
7:31
select my job and go for the simulation
7:36
and now here I will decrease my speed to
7:43
6
7:44
and I will play it
7:49
so now how tool is moving
8:01
so we can see from the top view as well
8:05
so in offset method it has removed the
8:09
material in very better way and it does
8:12
not left any stock material here
8:15
so which is fine for us now we will
8:17
close it
8:19
now we will
8:22
create a g code from our operations and
8:26
we will use this gcode in a universal
8:28
sender
8:30
so select our job and then go for
8:35
here
8:36
post process and select on it
8:40
and I will
8:43
share my gcode save my gcode here so I
8:48
will give some name
8:50
g code
8:53
for simple slot
8:58
simple slot underscore I will say R1
9:02
and I will save it in my folder and I
9:05
will save it so you can see that it has
9:08
shown me the
9:10
g code here the G-Code has been
9:12
generated
9:16
I will say okay
9:18
now gcode is the most common CNC code
9:22
which any CNC machine in the world can
9:25
understand it and we will see our g code
9:29
in a universal gcode sender which is a
9:31
open source software
9:34
so if you search over the Google
9:36
Universal G-Code sender so you will get
9:39
here the GitHub page of the universal
9:41
G-Code sender
9:43
and just
9:45
install the latest version by going to
9:47
the download sections here so install
9:49
this stable release if your system is a
9:52
64-bit
9:56
as I have already installed it so I will
9:59
show you
10:01
then go to the once you extract the file
10:05
then go to the bean and go to for the 64
10:09
bit
10:10
and run it
10:12
so your Universal G-Code sender will run
10:24
now this is our the universal gcode
10:26
sender and here I'm not going to much
10:29
more about the Machining operation of
10:32
the part but here you can select your
10:35
firmware
10:37
and select for the port and then connect
10:41
it
10:44
so this is the universal G-Code sender
10:46
you can use for the Machining operation
10:48
and I think I have not much more
10:50
experience about its Universal G-Code
10:52
sender but if you search over the Google
10:54
then you will find lots of tutorial how
10:56
to use the g code in a universal gcode
11:00
platform
11:01
so this is the very basic tutorials
11:04
about the removing the material of us of
11:08
a slot with the help of a path workbench
11:10
and create the G-Code and import that
11:13
gcode into the G-Code sender
11:15
and in upcoming tutorials I will cover
11:17
the more operations like G-Code for the
11:21
holes and
11:23
any parts which has the surface finish
11:26
and we required the stock of the
11:28
material
11:29
so overall overview of this tutorial is
11:33
to get familiar with the path workbench
11:35
this is a very basic tutorial and I will
11:37
come with more advanced tutorial on a
11:39
path workbench on upcoming future
