What is the final answer on wiring the Sigma 4 winding Stepper motors to the Gecko? The Signma's are actually an 8-wire Stepper, some of the wires have been connected together at the motor, as show...

I have a Bridgeport BOSS 5 or 6 tape reader off a rigid ram mill. Does this item have any value?

Anyone interested?

I spent some time looking at the mill and found that the problem with the Y-axis. It was just a fuse.
The original hardware, although old and very bulky, works fine. So I will pass on the Geckos...

ON this subject of using Geckos on a BOSS with high current Steppers, I received this from Gecko:

Our drives max out at 7A, which would give you 87.5% of your maximum torque at full power for an...

Do you happen to know which drive motors you have. Apparently the issue with the Gecko is its limited current, and I'm getting the sense that some of the BOSS machines had high current motors.

I...

I just looked at the Larken website. Frankly that low budget website and the adequated board in the picture turns me off. The board is using through-hole components. The world moved to surface...

My situation is that I repaired the original BOSS 5 Controllers and interfaced them with a simple parallel interface via lazyCam. But last time I used it the Y axis quit just as I finished a part. ...

Which Gecko's did you put on the BOSS 5?

Anyone know of a strong sales rep for plastic injection molding? We are looking to bring aboard such a rep to help our business survive given that China is draining all customers away.

Some time back I came across a post which I can't find now. The post's author described a Sales person that came to him and said that he would bring in new customers if the machinist would give him...

Its been a while, but as I recall a VFD was going to be a problem because I not only had the motor to drive, but the BOSS 6.0 power system. I remember folks commenting that the VFD would not work...

Well the problem is that the Mill motor is passing through a overload breaker. As the mill runs, more power than usual is flowing throug L1 and L2, so eventually the breaker heats and it pops. ...

I built a Rotary Phase converter some time ago. The 2HP idler motor starts and runs great. The 2HP mill motor starts fine when the idler motor is running. If the idler motor is not running, there...

If Bobcat has relentless salesmen as decribed on this forum, then you know they have salesmen posing as users on this forum.....and I think its fairly obvious to see who they are. I would not...

I could not view your attachement. In SE go to "Insert" then click "Image".

The trouble with SE should be obvious by looking at the number of posts here.
No one is using it, there is no pool of users to help answer question. There is a news group, but the activity is...

I don't mind shelling out a few bucks, I just want something that will be around a while and its worth the effort investment. At the same time its got to be simple. I really dont want to become an...

I have a 3 axis CNC mill and currently using Mach 3 to control it. I have no CAD/CAM software so I have just been using the simple wizards in Mach 3 to do crude milling.

Can you recommend CAD/CAM...

Geof.

Are you saying that the cast iron can't be welded?
unrelated to the above, I actually welded a steel plate to a cast iron steering box and if it is likely to crack, then its not safe. ...

Yes, it is Cast Iron. Are you clairvoyant? Ok, let say its been effectively quenched and is now hard. Shouldn't an M42 cobalt bit cut the raised portion of the weld?

I had a item that I had to weld a crack on. I used my Mig Welder and added a quick bead. The surface that was cracked is one that has a gasket so it needs to be machined smooth.

So I put a...

Do you have a picture of your setup? What do you use as a nozzle? Which coolant do you use?

I want one!

What if instead of rounding off the back of this clamp, you kept it square. And in this now square portion of the clamp, drill oil passages, so that externally, there is only one oil...

My brother-in-law owns a small plastic injection molding company. Essentially he builds the molds and then he runs the presses to create the plastic pieces.
The thing is, he has all manual machine...

Ah, you read my mind posting the image

One thing, this guy mentions how mist cooling is only 90% as effective as flood coolant. Given the minor amount of coolant with this no-fog approach, it...

How is this different and do you have any plans?

I'm looking for a recommendation on a coolant system for A BP II CNC Knee Mill.
* I don't particularly like the idea of a mister as I don't want to be inhaling the mist.
* The flood type seems...

I don't quite understand why everyone is recommending a two-flute end mill and high RPMs. Wouldn't a four flute provide the same at half the speed, or provide an even better cut at the same speed?

Al, I don't think you read my two line respone completely. :cheers:

So this would say that I could have a 0.66 to 1HP RPC for my 2HP 3PH spindle motor....when its running, and at least a 2HP to start it. So if I have read you correctly, a 2HP is the right choice. ...
