I did find some more info on this - the differences, if any are slight. In single pulse mode - which virtually everyone uses,
you must first send the enable signal (if you are using one), then wait...

On a number of the stepper motor drives I have seen dip switch option for 'double pulse" mode.

Basically if you want to go CW you send a pulse train only to what would be the Pulse Input on the...

Thanks for the formula - didn't see that before.

the manual for the 34 says - 1.4 ohms and 3.9 mH
the 23 is 1.0 ohms and 1.6 mH

the torque / voltage curves on virtually ALL of the stepper motors I have seen really show a big diff moving from...

2.8 amps per phase for the 34, and 3.0 amps per phase for the 23.

Good idea about checking for voltage drop - did it and no there is none - volts 36.2 before and after turning on off drivers +...

Drivers are max 4 amps I have them set at 3 amps. 36 volts.

Will add - just hooked up the 34 to the same driver as the 23 and the watts dropped down to between 26 & 27.

And the power supply with no load on it shows 5.1 watts. = 27 - 5 = 22 watts for a...

Just what the title says - I have a couple of steppers I am testing out - I bought a 200+ oz-in nema 23 and a 450 + oz-in nema 34
hooked them up on my bench the other night - 36v power supply. Then...

Two Kurt ML35 Vices

These are two Kurt ML35 vices I bought a few years ago for a CNC project that never got off the ground. The vices never spent any time on milling machine, they were just used...

I bought a new Sharp 2412 in December - and I bought a RPC off of EBay - just some generic thing - had to send unload it on Craigslist because the instructions sucked so bad I couldn't figure out how...

with low hours on it (1500). This has the FADAL 88HS control on it. I know next to nothing about these. Anyone know if they would have had Macros (or something like them) on one of these ?

Also...

This has to be the most awesome shop I have ever seen. I know you were going back and forth about the time and money, but I think it ended up a true work of art. You should be very proud - and I bet...

No offense - I don't like this.

One of the major reasons I came to this site was to check out the classifieds - they were simple easy to use and interesting. If I want an auction I'll go to ebay...

I've got some idiot questions about CAM software ... basic things I've never understood. Keep in mind that up till now I've never used CAM software on my mills, just straight GCode.

So one of the...

mwteng - I sent you a PM.

Go to the sister site for this place :

I put a couple of RFQ's out there and got very good pricing and awesome service. Put a post out there and see what you get - I bet...

I use TurboCNC (TCNC) and like it a lot. If you got the can't find tool message (ignore it for now - I still don't use a tool file), I think you have already managed to start the TCNC software. I run...

FWIW - I have a Tormach (1-1/2 HP) - and just got a 2-1/2" Sandvik facemill from EBay. It's overkill for my machine, but I did get it to work pretty well, makes a mess of my shop tho :) - throws...

I also started out looking at the TM-1P and then found the Sharp, which is clearly a much better deal (1181 IPM rapids vs. 400 for example). If you take the Haas and add ANY bells and whistles (for...

Got two sets on EBay with racks - $ 45 TOTAL - work great.
Clamps is clamps - not like they're precision tools. IMO

price went up a bit :...

Thank you Mr. Hu - some good information there !

As a newbie I have a lot of things to learn - one of the hardest is the combination of feeds speeds and tooling. I am getting better tho :)

...

I have some 15 inch long 2" pieces of mild steel angle iron that I am trying to get a nice mirror like finish on one of the faces. At first I used a cobalt end mill to rough mill it down and then a...

I'm looking at a milling machine that has a 7.5/10 hp spindle - does this mean the spindle puts out 10 HP peak ? and 7.5 is max sustained HP ? Or what ?

Anyways, I already have a new 10 HP RPC,...

I hate Mach3 and while we're at it, I hate those those little screwless vices too - they're a real PITA to set up :)

TurboCNC rocks - especially if you have worked as a computer programmer for...

Anyone ever change out a cartridge spindle ? I have a Tormach and am considering going from the R8 cartridge spindle to a ISO/CAT 30 taper spindle. Anyone give me any advice on how hard this would be...

-
I have a Tormach with the R8 spindle cartridge - and I am considering changing it to the ISO 30 so that down the road I could build a simple ATC. I have the Tormach Tooling but I think it would be...

No offense, but some free advice - if this is your software, your demo is painful.

Can't make the movie go forward, goes thru lots of irrelevant stuff.

I don't want to see a slideshow, I want...

Are you still planning on buying the Sharp ?

I would be curious to know you thought processes versus buying something like the Hass TM-1P. Right now these two machines (the 2412 and the TM-1P) are...

This company : http://www.terabyteunlimited.com/

makes a product called BootItNG which in spite of the funky name is the best software I've ever acutally paid for :) It's mainly a boot manager -...

Wow !

Doug thanks for all the info.

I think it wouldn't be terribly hard to run a coolant line from a tank - Enco has some heavy duty pumps, and I know on my much much smaller mill I was able...
