Linear Encoder With Syil x4

[obrif]

Would like to connect a linear encoder to a syil x4+ does anyone know any
wiring layout and mach3 settings?

The scale would act the same way as an encoder and go back to the drive as normal for servo control.

Would an linear encoder feed back into Mach3???

Does that mean your would get position feedback in a stepper setup?

Adding complexity is not an improvement. What do you wish to achieve.
More accuracy. How will you measure the improvement.

The machine is already an excellent price/performance mix. Get real.

I see your point Neil, but if the guy wants to add it to his machine I think it would be cool. Particularly if it comes with a DRO and he later puts a MPG/jog in it.

I'm also curious to learn what would Mach3 do with that information...

[neilw20]

x4+ already has MPG, but needs Pablo's (peu) second port adaption to be useful.
Only cool if you put it on the spindle for solid tapping.

:LOL:

Complexity!!!

Yeah I agree...

If only I were converting a mill from scratch

Which reminds me...

Have you seen a stepper or servo being used as a spindle motor? Is that very different from what we have today?

X3/X4 spindle motor is BLDC and really is a servo motor.
Have you got your Y axis rock fixed yet. I just program in the errors as a tweak. I am really lazy, but churn out 100's of hours work on my SX3 every month.
On 15HP CNC lathe (OKUMA LC20), between centers, I held better than 0.0005" parallel all day and never could be bothered adjusting the tail stock which was 0.005" off center. That's why CNC is great. New tools. Easy solutions.

Thanks for the replies,

Since had one linear scale laying around would like to make screw calibration and arrange backlash on the mach pragram.
Till now managed to get 2 raw inputs bits lights flashing when moving linear scale but have not manage to get a reading on dro Can somebody help?

Read The F*!!@-riendly Manual, Mach3 section 4.5

You have a quadrature signal. Without special electronics, you will be limited in the speed that the encoder moves before getting errors using Mach3.

Not yet. I started to scrape it with varied levels of success, but I would like the reassurance of a flat reference... still, I'm getting better at it and I think I can wing it just with machinist blue.

I have a thread on the main metal working forum, but no suggestions for a cheap reference yet Reference Flat for Scraping Dovetails

*sigh* One day I hope to build a machining center from scratch

Managed to get the encoder readings in the screw mapping windows to a micron accuracy at last thanks to the ^%cken helpful SYil Manual and MAch Manual.
Am just playing around with the scale but results are leading to around 0.1 mm HORIZONTAL PLAY in the X4+ head. Is this normal or it can be improved?
