thanks but im not buying anything from china unless i really have to, not after my fiasco with ebay seller igoodmart2011

I actually ordered a couple of each size from toolstoday.com :)

read my build log, i have mine setup with ebay proximity switches and they work great, I'm getting repeatability within .002 in

While i'm waiting on some parts to finish off my dust shoe,

Imma start messing around with aluminum. Did some searches and i think i have the jist of what i need to do. anyone have any thought...

Here's my dust shoe after tweaking the machine and getting it dialed in. Looks a lot better. Also a fresh bit helped a lot.

thanks everyone,

That seemed to have solved it. I slowed down the plunge rate, added ramp to the tool path, cut depth at half the bit diameter, and now my circle is a circle.

I guess, I was...

i notice his building laser engraving machines with wood also... (nuts)

just asking for trouble......that's all im gonna say...i'll agree with others his prices are way too high for what it is.

what cause's this?

You really only need 3 sensors for homing, just use the ones you need for now. you can add the ++ sensors later. This will help for troubleshooting.

For homing to work properly (without having to...

g540 maybe shielded.. but your limits switches most likely are not.

correct me if im wrong, but I thought setting a higher denounce level rejects more noise, not a lower level. my debounce in mach...

I just need to locate a brush/skirt for my dust shoe...Looking for something that can be sourced locally some suggestions were paint brushes, leather, vinyl, anything else that can be had locally..?

I'm not sure if the bit is downcut or upcut. its cheap. I'm gonna order more quality bits.

also just thought id post a follow-up to my spindle issue. The seller Igoodmart2011(amonstar) got what...

Thanks I just completed another test cut after doing the auto steps calculation procedure.. a couple of times actually. Its better but still not spot on, I think I can live with it.

I made a...

i did some test cuts to measure what my accuracy is currently and the cuts are coming out smaller than it should be.

I cut a 5 in square pocket and it came out to 4.910. I was assuming that the...

Will do, I think the first project will be a dust shoe.

Those of you who ask about the modbus setup for the hitachi. Here are the instructions with the mach 3 brain file. You need Microsoft word to view it.

alright i figured the problem out.

I set my speed in home and limits setup to 10% instead of 20% now it doesn't hit the switch and my repeatability numbers increased

here are the results of...

yes its get ground through the power supply source, it just switches the signal over.. that's what i meant I'm using dpdt switch with center off, for manual auto/off/on control

the drawing shows...

that's not possible the blue area on the switch is the sensing area. they need to face the metal.

or maybe im not understanding what your saying.....

edit: I understand what you mean, put the...

yes you need an external power supply, the vfd pins cm2 and pin 11 are ground terminals.

here is the updated drawing. i been meaning to update it on the forum

proximity switch test doing all ref home. Note: i need to adjust my switch a little because its physically hitting it before it stops. but the number seem pretty accurate doing this test

EDIT: ...

Finally got my proximity switches setup and posted a video to test repeatability. Hopefully I did this right but seems to me these have decent numbers.
what do you guys think?

proximity switch...

Made some more progress today. Finished up rewiring my new additions to the machine and also messed around with spindle control via modbus using my Hitachi x200 vfd. Nice to have it automated in...

My vista cnc pendant arrived today. I opted for the mpg model. I haven't used one with that feature before, so I figured I'd try it out. It was a lot less than the previous pendant I owned.

6mm ID x 8mm OD, they all come in this size, unless you buy from someone that has already modified them to fit standard sizes.

fresh from ups. camera flash makes the color look off in the photos.

edit: mounted and all wired up photos added.

Finally received all the stuff needed to complete the wiring for the limit switches. Taking your advise, I decided go this route. I've got one proximity switch for the a axis, one switch for the y...
