  So where I work they are wanting to get a 3D scanner and I have been tasked with finding a recommendation that
is around $1000. So far I figure the Einstar Shining 3D scanner would probably be the one I recommend. That said
I know there's always something that I am missing. The scanner is just the hardware part the bigger issue would be
software. I am tired of the subscription based software paradigm. Though it looks like this model Einstar uses a free
version of there software. There is an open source software called MeshLab but obviously I haven't used it. 
The 2 basic questions would be
1- Has anyone on this forum used the Einstar Shinning 3D scanner, and how did you like it?
2- What software do you use with it?

Any chance of adding a "save" button for the code viewer? I see the "save_as_pb", I'd rather just overwrite the existing file without a prompt if it's possible.

I am not competent to give you advice on the feasiblity on this project, but LinuxCNC is unlikely to be a show stopper. It sounds like an awesome project. Please include some pictures so we can see that machine and what you do with it.

I implemented my pneumatic collet closer, back gear shifter, and tailstock using some inhibits in classic ladder and command them with M64/65 Px. This would be one option for controlling your hydraulic  tailstock. Most would probably do this more elegantly with a custom comp.#Collet closer - created 23.10.22

# --- Collet release
# --- toggling footswitch
net collet-foot <= [HMOT](CARD0).7i84.0.0.input-16
net collet-foot => classicladder.0.in-00


# --- collet closer outputs
net collet-close <= classicladder.0.out-00
net collet-close => [HMOT](CARD0).7i84.0.0.output-10
net collet-open <= classicladder.0.out-01
net collet-open => [HMOT](CARD0).7i84.0.0.output-11

# --- Spindle inhibit
net spindle-enable => classicladder.0.in-01

# --- Turn on pneumatic SOV---
net machine-state <= halui.machine.is-on
net machine-state => [HMOT](CARD0).7i84.0.0.output-00

I have not using any kind of global variables ... and therefore it is little bit tricky to me 

I have changing mode of operation of servo driver from Velocity 225 to Position 224 ... When I have netted the single one pin for example - from joint.0 to component.0 and others have hard setp opModeCode 225 ... working only single one properly on homing sequence well

But when I netted them all ... every component driver 0.1.2 for example want to change the operation mode for homing just in the moment of single one of then all other are changing too ... I not really understand what is going on but only solution which is working is to create custom component for each axis ... which works well but I do not want have extra custom components when single one with instances should do their jobs same well...

Hello Folks,
I'm thinking hardly about acquiring a used Mazak Integrex200Y Millturn machine.

It uses and old Fusion640MT control with floppy drive data input. I'm planning to use Fusion for the CAM side of things.
My purchasing decision is a bit dependent on the feasibility of the project in terms of LCNC retrofit. So far i have the following requirements and parts of a solution for it:

Starting with the

Kinematics:
Since its a 5 axis Mill-turn machine i need a custom Kinematics file with switchable TCP function. Additionally the Y-Axis is interpolated with the
X- Axis and an auxiliary Y1-Axis.

Axis in Question:
X - Linear
Y - Virtual Linear
Z - Linear
C - 360° Rotary
B - +/- 90° Rotary


I've played around with ChatGPT and it seems to be somehow possible. But i would prefer an answer from a knowledgeable human being

Hardware:
I found the cards from yurtaev.com. So it should be technically possible to reuse the old Mitsubishi spindle and servo drives.

Turning + C-Axis + Clamping:
Since it is a Mill-Turn, the lathe spindle can be used as a traditional turning spindle but also as a C-Axis for 4/5 Axis simultaneous or 3+2 with clamping. I assume this involves also a bit of PP work to tell the machine when to clamp/unclamp ?
Is this possible to implement in LCNC ?

Hydraulic Tail Stock:
The machine has an hydraulically activated tailstock that moves into position by the help with the Z-Axis. I assume i can implement this functionality
with custom M-Codes and some work in the PP?

EDIT: RotarySMP Pointed my in the right direction, i will use a custom comp.#

Postprocessor:
I've read in the forum that the Fusion Nakamura-Tome Mill-Turn PP is quiet well implemented by Autodesk. Since it is for a Fanuc Control, it should be less work to get it going for LCNC? Or does anybody has a better idea?

In general I'm interested in your opinion of the whole project and please tell me if I've overseen some major pitfalls.

Thank you all in advance!

Kind regards,
Jochen



 

With system I ment the drive and motor. They will not "know" if I pulled the plug on purpose (punishment), because I did not know better.
Or if the lost connection were due to wear and tear or insufficient assembly (not to be punished).
So my take is that I need to pay more attention to detail in the future, because I might have damaged a drive or two without beeing aware of the importance of the wiring.

Is the kerf width being compensated in SheetCAM or in QtPlasmaC?
Never on both.

Yes running linuxcnc plasma post processor and I’ve checked arc fitting tolerance and it’s the same as sheet cam on windows that works.

I'm working on a second version of a rotary union, i feel good about this one working but until it's built and tested it's all wishful thinking I'm just going to make short videos as i go and post progress. it seems like it is an interesting topic, and it seems justified to spend the extra time on that end.

How's the rigidity of the harmonic drive? I'm thinking of using mine as a B axis for the spindle. I will find one size smaller with a faster reduction for the table mounted rotory A or C axis.

This is the call that starts the touch probe routine with those settings.
Here is the actual probing program code.

First - I have NO idea what I did to fix it... but it is working now. I feel like I 'proved' the Infinite Monkey theorem ...(en.wikipedia.org/wiki/Infinite_monkey_theorem)

That said, when it WASN'T (or being pessimistic about the the future - when it DOESN'T) working, the target you refer to, was appearing but the DRO was not zeroing.

I'm going to do a text comparison of the now working INI and HAL files with the almost working INI and HAL. The almost working files allow me to start the router, move it around and homes without error... except it does not zero the DROs.

Guessing but it sounds like the component uses global C variables.
Check out 8.4 here linuxcnc.org/docs/html/hal/comp.html#_per_instance_data_storage if relevant.

Hello Gentlmen,

Excuse me, but once again I am facing weird behaviour of custom components file during its programming... 

I need 3 axis there fore I am using a 3pcs of components in the .hal file via count = 3..

I have many IOs stuff because component will communicate with profibus DP driver and it is basicly same as with ethercat but little bit different(other story) But long story short.. when I am homing there we have a custom homing subroutine and modes of driver are changing etc.. issue is comming - I have starting homing with single axis(over internal subroutine), any of them and mode of driver operation is changed over all components==all axis .. what exactly help me right now is have custom names of same component each but it is little bit tricky...

What the behaviour is this overflowing from one to other component in the single instance of lcnc?

Thanks En....
