Lathes and Turning / Re: Lathe X and Z change
« on: March 28, 2020, 12:38:32 pm »
Exactly. I used only main spindle, + the rear part that captures the collet.
The rest was thrown away as such spindle was the cheapest option at that time (about 65€ delivered price 3 years ago).
After couple of months working with collets only (mainly 8mm), i decided to go with 3jaw, due to better and easier clamping + 5c collet always pulled the part inwards a little when tightening it.

I've made my own housing and all the needed parts for it and I'm using it for 3 years now.

On bottom video, I was still using 8mm 5c collet and it was powered with Leadshine 8nm closed loop stepper which was mounted directly onto the side of housing (i don't have any pic of it)

The tool is always mounted. I never take it off. And I need it only 3-4x per year when making my turned part on stock.
Turning head is made out of 5c Spin index which I disassembled, added 2 bearings and made own enclosre with bearing seats.
I can work with 5c collets, but currently i'm using 3jaw chuck which mounts into 5c from spin index.

First I have used stepper motor for turning which was attached directly onto enclosure, but have changed it and now use 3phase motor.

Tool is just screwed onto Z axis on Spindlemotor side :) , no extra tool holder. As I only use 1 single tool

Hi.

Have managed to do it yesterday, but had no time to reply.
I've had XZ setting already, what it helped was to use Mach3turn post processor instead of LinuxCNCturn.
After that changed X<>Y and I<>K and it worked.

As I have turning head mounted to my table, and cutting tool is mounted on my Routers Z axis.

That I've tried already, but always getting error "Radius to end of arc differs from radius of start"

Lathes and Turning / Lathe X and Z change
« on: March 26, 2020, 16:51:27 pm »
Hi.

I was using my milling machine also as lathe, where I had extra setup with switched axes in LinuxCNC, so X became Z and Z became X.

I was wondering how to convert the Cambam Lathe output so it would work with regular setup, so I can only put my rotating A-axis onto table (i switch it on/off manually).
I would need to convert output code to X become Z and Z becomes X.
I'm playing with it now for couple of hours, but can't find a working solution after changing x->z and z->x in g-code.

Any help will be appreciated.

Looking good.  Why the 7i92?  

The 5i25 will handle a machine like that just fine.  

As I do want to have it ethernet connected like the current one where I just added 7i92 between computer and current parallel port BOB. And at the end, both cost same price, 5i25 and 7i92.

Will use same Parallel port BOB on new machine as on old one. Running 9+ years without any issues. Benezan Advanced Interface.

As i do need second mill for smaller jobs, i decided to make second one by myself
Parts were drawn in sketchup and CamBam was used for making the programs.

Machine is made out of aluminium profiles, and 6082-T6 Aluminium plates.

It will run with parallel port, which will be later reconected through Mesa 7i92.

Here some pics from the process:

I use custom M codes for switching form angular to continuos rotation and for start/stop of a axis.
With notepad++ I change the G-Code as mentioned above

I have my licence number printed out and stored with my bill, plus I still have the mail with licence from 6 years ago.
So it cant get lost easy :)

Hardly waiting to see what next relase will bring.

I'm glad everyday that 6 years ago I decided to go with CamBam and I have tested many programs.
Cambam was and still is most value for $$$.

I use BOB with LinuxCNC.
Have 10mm pitch ball screws and can go up to 18m/min at 2000 steps/rev.
I'm using Leadshine 8Nm easy servo motors with 75V.
The same motor is also mounted on my 4th axis.

I'm using LinuxCNC and have it configured that I can change from normal A axis to turning mode with M100 and M101 custom g-codes.

Video of my first test in one thread below.
