Tangent Corner / Identify Servo Drive Brand

« on: May 30, 2023, 04:25:43 PM »

Just a poor pic of 2 servo drives.
Trying to determine the brand.
Anyone recognize them ? maybe by the red stripe ?
They are in an older machine that I am considering salvaging.
Thanks for any help,
Russ

Bargain Basement / AB Servo Drives BUNDLE

« on: October 06, 2021, 05:13:39 PM »

  Hi folks.
Going through my surplus/spares and have these 3 nice drives that I can part with.
These were checked under power with appropriate motors and cables and worked fine. Have been in dry, heated office-like storage since.
I've used this type on several machines and they are top notch. Being the Sercos type, they are Indexing as well .... VERY versatile.
I'll take $600 for all 3, or might entertain an offer.
Cheers

Tangent Corner / Cam lobe generator ?

« on: October 22, 2019, 11:03:06 AM »

  Hi folks.
I've got a project that requires a cam lobe of specified duration running in a yoke/fork with minimal clearance through complete revolutions.
 Say the yoke/fork had a 2" opening. A 2" diameter cam follower offset .1" from its shaft centerline would oscillate the yoke .2 per revolution.
But ......
I want an egg shaped cam lobe that will have a duration of lift as much as possible per revolution but always measure 2" diameter at any point as to keep the yoke/fork free of backlash. I assume it would be shaped sort of like a guitar pick. 
Is there a formula, or generator for this sort of thing ?
I can make a crude sketch if necessary.
Thanks.

Mach4 General Discussion / Failed to launch

« on: July 26, 2019, 08:20:13 AM »

I followed the topic regarding the new CV wizard and saw that I needed to update .... so I did.

Brett :  "If you do not have mcCvDistToleranceV001 in your wizard list you probably need to update."

Ran the new version and there it was. Very nice work Brett !

I go to start the SW today and get this (pic).
Reloaded the package and same thing.
Dwnld from the site again and reload ... same thing.
Can you tell me what happened ? ?  that it only ran ONE time at the very first attempt only ?
Thanks,
Russ

Tangent Corner / Bridgeport Spindle Bearings

« on: April 16, 2019, 02:38:52 PM »

Hi folks 
My SuperMAX knee mill is almost ready for new spindle bearings.
It has the Universal Quik-Switch 200 nose but is the same as a Bridgeport regarding the bearings.
I looked around a bit, but am wondering where you more experienced folks would normally go to purchase a set. 
New or refurbished ballscrews are next ..... if there's any $$$.$$ left in the kitty. 
Thanks for your time,
Russ ... in Eastern WV, USA

General Mach Discussion / Goofy forum layout

« on: March 27, 2019, 06:23:36 PM »

  Is my system on the fritz again ? ? ? or has someone busted the forum ?
I get unwanted videos running that I cant turn off and navigation is much more difficult than before.
Thought I was in the wrong place initially ..... (maybe I am  )
Thanks,
Russ

Tangent Corner / Hmmmm .... let me explain.

« on: March 22, 2019, 04:16:45 PM »

I'm hooking up a second BoB to my USS using the ribbon cable to the DB25. Male to male ... dang it.
I said "I gotta run to the Radio Shack and get a gender changer".
She said "I thought you went to the clinic for that".

Tangent Corner / We've come a long way .... sort of.

« on: March 19, 2019, 12:06:32 PM »

 
I found this old vest pocket book in a tool box bought at an auction.
Printed in 1901.
Was Tesla unrecognized at the time ? He's not pictured with the others ..... (I left that one pic large so you can view it and zoom in if you like)
BTW, no mention of LED's either

Mach4 General Discussion / CNC drive AXBB-E

« on: March 09, 2019, 08:17:33 AM »

Hi folks.
Anyone here have any experiences with the CNC drive AXBB-E combination board ?
At first glance, it looks to be quite a nice package. An Ethernet controller priced reasonably with well documented instructions.
Thanks for any input.
