Hey All, 
I was given an old Roland MDX-540 ( www.rolanddga.com/support/products/milli...0-3d-milling-machine ) and was wondering if its worth trying to LinuxCNC convet it.
Any thoughts? 
I can currently use it with aspire then using the roland software run the gcode. No live tracking though. and aspire tool paths are a bit of a mission to setup. 
Cheers

Hola noqui.
Tengo interés en realizar el proyecto tal como tú ya lo hiciste y necesito en primer lugar saber dónde puedo conseguir esta tarjeta la db25-1205.
Te agradecería mucho que me orientaras al respecto y a futuro pues tenerte como referencia para el proyecto que deseo realizar.
Si fuera posible me gustaría tener tu correo electrónico para contactarte directamente el mío es This email address is being protected from spambots. You need JavaScript enabled to view it. te agradezco altamente cualquier ayuda que me puedas ofrecer.

On my Schaublin, there are hal sensors for home/limits. The X is near max +X, and the Z is near max +Z.

I have set the all axis homing to first home X and then Z. I set my home speeds pretty slow. It is up to me to be sure the tailstock is pushed to the back end of the bed, and to ensure there is no tool like a boring bar mounted which would wipe out on the spindle during that first X move.

I haven't got my ATC working yet, but the whole concept of a safe tool change position on a bed type CNC lathe with tail stock and old rotating turret ATC seems aspirational at best.

  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.
