Can anyone further elaborate or comment on these limit switches?

Thinking...

If you are using a USB to RS232 converter, I would suggest ditching it in favor of a PCI Add-in card. The MiniMills we run at school have Dell computers which had to be ordered with the serial ports...

Mark,

I currently go to a university where we were entrusted with a bunch of HAAS machines; 3 MiniMills, 2 SL10's, 1 MDC, 1 SL20, a VM-3 and a VF-4. I could answer a bunch of specific questions...

Mike,

What would be the best way to implement THC on the TorchMate 1 system?

The waters have been exceptionally murky when trying to do research- the Torchmate website isn't terribly clear on what is (and is not) included in their kit. So far, if I were to purchase a TM1 from...

Did you use linear slides on the X axis in addition to the Y? Looking at the Hiwin rails, it doesn't look too expensive to add linear slides on the 8 foot sections.

Also, given their current...

I'm looking at a new Torchmate 1 system- would it be advisable to order linear slides for both axes? (Does the end-user provide a linear rail system or is one included in the TM1 package?) I'm...

I'm well aware that the 1/4 HP motor setup does 10k RPM :) I own one. My intention is beefing up the motor, so that it still spins at 10K RPM but has a lot more grunt to push a face mill at, say,...

Well no, I wouldn't be trying to spin a 1.5" face mill at 10k RPM :p I would use 10k for things like aluminum and/or copper. I am a beginning machinist, so I need to find out appropriate speeds in...

I am going to be doing cuts in copper, delrin and aluminum. Flood cooling to evacuate copper chips seems like a necessity.


You mean the motor that comes stock on the Taig?

I guess I have two...

I'd say that the motor wouldn't be able to drive that big a load (would stall or wouldn't spin fast enough for the inserts); Although the V-belt seems like it wouldn't be able to handle the load...

I do have the 10k RPM spindle, but a 1/3HP motor seems weak. Anyone care to disagree? I would REALLY like to be able to drive a 1.5" face mill.

I'm interested, but the whole "not made in the USA" thing makes me cringe. I'm concerned about quality, and if I'm going to drop $400 on a 10,000 RPM motor and controller, I would REALLY like it to...

haha- I will call them on Monday and ask if they can get me an exact weight of the motor- that may be its "pack" weight, so it + the box it sits in. We'll see. It seems VERY heavy for just a motor,...

From this page, it says that the motor weighs 34 lbs.

I wonder how much force is put into clamping those brass pieces into the column. I think that's a great idea though, it definitely looks sturdy. I wonder if they bolted the uprights in place though?

Hi Dave,

That looks awesome! What material did you make it out of?

I was planning on picking up a 1.5" face mill. Although my opinion on the matter is completely unfounded by fact, I thought that a 1HP motor would be able to handle that kind of face mill.

As far...

Was looking around, and found a Leeson 1HP 2500RPM 90vDC motor available around $400. Trying to drive a 1.5 or 2" face mill in the Taig, so having plenty of power available would be handy. Any...

Hi Andrew,

First off, thanks for the reply- I assume you've worked with face mills before- I have not, except on the HAAS minimills at my university.

How much horsepower do you think a 1.5"...

Over the summer, I will have access to many machine tools in my university's machine shop. Most notably HAAS CNC MiniMills, a VF-3 and a VF-4 (4 axis).

My objective is to design and construct a 2"...

Does anyone here maintain a backup of the chicobritish page? I wanted to see his motor mount but it looks like the website is down for good :(

Just finished buying 3 G320's. Any progress on these?

Question for you Mariss (Or Marcus): Would upgrading from a G320 be worth it once these are released in your opinion?

Ahh, I see. I apologize. Should have looked more closely :)

So let me get this straight- If I shut down the AC side of my DC power supply (28v going into the G320), it won't have any ill effects? But if I open the circuit on the DC side (say, with an E-stop...

Aah- Now that I think about it, that makes sense. Any way you could walk me through how to do that method (measuring)? Seems like it's the absolute best way to go from what I've re-read now :)

Awesome, I'll give that a shot, too. Thanks! Although, I think the method we've done is a bit more scientific and (perhaps) more accurate.

Okay, great- That value sounded a big high so I wasn't sure. But thank you for the confirmation :D

'Afternoon everyone,

Looking for some help on motor tuning in Mach3. To provide some basic background, I am running a PMDX-122 breakout board, a Gecko G320 servo drive, and an IMService servo...

Even though I own servo motors, Mariss (hint hint :)), I admire your work in trying to reach the lower-end of the market for entry-level home shop machinists.

I'll be buying 2 more G320's in the...
