Very interesting. i will have to check those links out later.

Hi. I was wondering if the Avid 5x10 Router table is suitable for conversion to a plasma table? I know it is possible, but is it reasoable? Thank you for your advice. -Mike

Hi.

I just picked up a Gerber 408. I saw the colossal controller box and only being familiar with small stepper machines and mach3; I am unsure on how to proceed. It did not come with the...

Thank you for the feedback gents.

What are your thoughts on:high speed spindle 1KW, 1.5KW, or 2.2KW; and a Brushless servo motor 759W - 1HP; (industrial sewing machine)?

why would you choose one over the other?
Pros/cons of high...

What is the difference in running a lower RPM setup such as the OEM motor or even a Brushless servo motor and say a 24000 RPM spindle?


What would be the pros/cons of these styles?


I did...

Found the club. thank you. I have looked at a few of the threads on ATC and well keep searching through there.

Thank you Bob!

That makes sense. I did see a thread of a man who changed his motor and pulley section. The motor is about 1HP stepper sewing motor I think, and a R8 Mill Headstock for the Taig...

Thank you VERY much for the reply. I really did search, but since the ballscrew version is only a couple year old, I could not tell if the numbers I came across were for the ballscrew or the older...

Hello. I am trying to get a number on the worst case part tolerances to expect on a Taig Ballscrew Milling Machine?

Lets say a 2" diameter part cutting a cylindrical shape in 6061 Aluminum. How...

Ok, Got it. John, you are correct, I am talking about the demand for amps from the wall. The outlet only has 20AMP breaker and I also wanted to make sure it was not going to be a some HUGE energy...

Ok, I have all the power supplies now. The resistors are enroute from China.

Two questions:

1. Do I NEED the diodes? Can I have a switch disconnect from the drivers until all the power...

BTW, the drawing was excellent!!!! Thank you John.

Hi John,

Amperage requirements may vary.

My steppers: 3V, 3A, 3.5mH, 270oz. in.
My Drivers: 4A, 42V

As of now, I am set to use 3 of the steppers (already purchased) at 36V and 3A.
...

Excellent. Thank you Roger. Everything is very clear now, except for the connecting power supply cases one to another.

I asked: Do the three Powwer Supply Metal Cases need to be electrically...

Hi,

I have 3 ATX Power supplies on hand and I want to run them in series to get 36V for a diy CNC Plasma Table I am building.

I read through the entire thread on daisy chaining them, and read...

Luc, I made the same purchase. 3 "Upgraded TB6600's" for about $8 ea on ebay, but they had this other chip. On Amazon, 18 people purchased the same thing and all of them gave it 5 stars. Anyways, I...

I am making a 42V DC Unregulated Power Supply from a discarded Microwave Oven. I will use it on the CNC plasma cutter I am building.

I am requesting a sanity check to see if my design is correct...

Oh my, well the ebay listing stated TB6600. Antone know what I ended up with?

wireb, the info from the IC is:

I purchased these "UPGRADED" TB6600 32 segments 4A 9-42VDC and some 3.5mH 270in oz Nema 23 Steppers.

On a good note, the heatsink did have the paste. However, being unsure what upgraded means,...

Thanks for your responses men. Eldon_Jon, sorry for the confusion. The ebay links says: Package Incluides-23HS8430. The longs page has a different main motor, but it has a spec sheet on the page with...

What is the real deal on inductance numbers?

I find an mH (inductance) on a motor such as this model 23HS8430 then I google the motor to verify the specs and find this spec sheet telling me...

jfong, I have done a ton of reading on the effect of inductance since you shared with me the tests you ran. Question: while you stated that below 2.5mH your stock TB6600 did great, I have discovered...

Ger21, thank you for your response.

I hope to answer the question on paper, not with a dyno, so I will look for Mariss's post.

3Seconds? I am surprise it took you more than 2. You are not...

I am trying to learn how to calculate the speed/torque data curve. Clarification: a 270 in-oz stepper drops that torque as it's rpms (speed -volts) increase. ie. inversely proportional.

I have...

109JB, thank you for such an instructional response. Most helpful. I am almost certain I am going to take the risk and try the TB6600 on the plasma build.

Jfong, thank you for sharing your test...

JB109, thank you for your response. I spent the night reading MassMind's info on stepper/driver selection. From what I learned there, combined with your response, I am deducing:

1. The TB6600s...

I found this "UPGRADED VERSION" on Amazon with 5 star rating from all 13 purchasers. Then I looked at ebay and found the upgraded version for under $8. I searched this thread and the forum for the...
