I hope you intended to say 1500?

You're doing a great job, I can't wait to it see it making parts!

**Azalin** · 05-20-2017, 09:49 AM

Yup, 1500 RPM.

I'm glad you like it.

I finished the model for the indexing wheel. I'll be using two C3 from cnc4pc.

Bad thing happened. I broke the 2mm end mill during the cutting and I had to continue with 3mm end mill. This cause a little larger slots. Do you think it will still work?

Yes. The slot width makes no difference.

Nice progress you are making.

I don't recall what control you're using but if it's Mach you will use only single-slot indexing.

@RotarySMP thanks Mark.

@DICKEYBIRD
I will start with Mach which is familiar to me then I'll switch to LinuxCNC.

Installed.

How many sensors do I need? I see some use 2 and some use 3.

One for the index slot, and then either another onefor pulse, or two for the pulse, spaced 90° of tooth phase apart, which would give you a quadrature signal. This means 4x resolution verses the single pulse signal, and the machine controller will be able to sense direction of rotation, which it can't off a single pulse.

Thanks Mark.

The spindle will turn only in one direction so I need 2 sensors?

**RotarySMP** · 05-22-2017, 03:26 PM

I used a similar encoder on my Boley

I planned for three sensors, but also only have two connected. ~50 tooth rev seems to work fine under LinuxCNC.

Thanks Mark.

Here's a short video of cutting the indexing wheel.

Just received the telescopic ball screw covers.

**Azalin** · 06-15-2017, 04:02 PM

Small update after my last post.

I've finally finished the housings for the telescopic ball screw covers.

And I've added an oil nipple for the Z axis ball nut.

I decided to use these connectors for the steppers and spindle motor. I also have military type expensive connectors but I like these more. 10 amps rated each pin.

**DICKEYBIRD** · 06-20-2017, 10:43 AM

You're making great progress!

Do you have a link to the supplier of those connectors?

**Azalin** · 06-20-2017, 10:55 AM

Thanks.

I got these connectors from an online store in Turkey. I don't know if they ship overseas but here's the links:
Female socket:
Mete 403012 5x10A Ã‡ok KontaklÄ± EÄŸik Makine-Online SatÄ±ÅŸ

Male plug:
Mete 403019 5x10A Ã‡ok KontaklÄ± FiÅŸ-Online SatÄ±ÅŸ

These are made in Turkey but I've seen very similar ones (actually identical) on ebay from the Chinese.

Same connector used on a spindle:

Not the same but similar.

Thanks, much appreciated!

Time for an update. I needed a 500x500x300 electronics box but these dimensions are very uncommon. So I had to made mine.

I added two place for 120mm computer fan for inner circulation. One will blow fresh air from outside-to-inside and other will blow the air from inside-to-outside.

I've used hammered silver paint.

Edit: I've used about 170 blind rivets. My right hand still hurts.
