Hi folks,

I'm trying to address my very noisy vari-drive. I have the motor and top cover off, but now I'm having these issues:

1) Can't get the top bearing off of the driven pulley shaft. Seems...

Solved: The cutter pulled the quill down. Took me a while to realize that could happen because of the helix angle of the tool. I'll go with lighter cuts and reef on the quill lock.

Hi everyone,


I just had a weird thing happen that ruined a fairly pricey piece of stock. The program was supposed to be making a series of concentric planar endmill cuts. Instead of being...

Who wants to circle some components for me to check out??? I know, sounds like way too much fun.

No motor hooked up. Tried L1 and L3 with the same result. If I blew something, is it likely to be evident if I open it up? If so, where should I look?

Ok, so I performed the reforming process but only took it up to about 145V. Based on absolutely zero knowledge of elctro-chemistry, I decided that should be enough to build up the oxide layer. During...

BOOM! Al for the win! Pretty much the smoking gun right there...hook up single phase to L1 and L2 and get a derated power of 3.5 kW. Why on earth they don't put that manual in the box is beyond me,...

240V +10% is 264V, so we're both saying the same thing. 265 is obviously a touch higher, but I'd be really surprised if they cut it that close. That's just the no-load voltage as well...it will drop...

It's a 2201, rated at 5hp normal duty. The last page of the manual says the AC supply can be up to 264 V.

I got my buddies transformer...it's a Powerstat 116, rated at 120V 7.5A. Does anyone know...

Ok, back in the office. Looks like quite the debate on which terminals to use for single phase input. I double checked the manual for this SK2201 and still find NOTHING about connecting to single...

Hey mac,

Really? That would be pretty sweet. None of the litterature says anything about that, though, and I've had a really hard time finding any drives over about 3hp that claim to take single...

No, only 2HP, but the drive doesn't have a single phase input option. Just using it for speed control.

Yeah, my plan was just to leave the barrel switch in the forward postition for now, and if I decide I like running with the vfd and want to keep it, bypass the switch.

I'm just using it for motor speed control. There is a barrel switch between the VFD and motor but I believe I kept it in the forward position.

Thanks!
Tom

Hey folks,

I got my hands on a new Emerson Commander SK VFD for free and figured I'd use it on my SB13 lathe. I hooked it up to the 3-phase power from my RPC and it powered up just fine. I...

Thanks everyone,

I've been at it all morning and I can't get the "bad" behavior that I saw before to happen again. I realize that I mispoke in my previous post...it was when I I couldn't get...

Hey Folks!
Wow, this exploded a little more than I thought it would. Sorry for the radio silence...I'm outta town this weekend and just jumped online.
So, I think we can establish that there's no...

Thanks guys. I actually ran into this problem a while back and managed to come up with a workaround that wasn't ideal. Now I can't remember what combination of strategy and parameters caused the...

BOOM! That seems to have done it. Thanks for all the help! Looking forward to keeping my tools intact...

Thanks! I'm not sure I follow exactly what you're saying. I opened the postprocessor in notepad and found "Arc move XY" on line 64. I changed it to "Arc move XYZ" (see picture) but that didn't seem...

Hello again,

BC for SolidWorks V4: I’m trying to confine a 3-axis feature to a certain area, but the lead-ins don’t seem to obey. I’ve tried both ramp and spiral, and they’ll both wind up outside...

Hey folks,
I'm using BC for Solidworks V4. I'm trying to do a 2D profile with contour ramping. Everything simulates the way I want, but the Post (Centroid_M_Series_Rev1.MillPst) is doing something...

Hey folks,


I'm trying to replace the vari-drive belt on my Series II (4HP). The manual that I have shows the motor hanging below the head, whereas mine (and every picture of one I've ever seen)...

I have the air coming from a pancake compressor (regulated at 85 psi) to a regulator on the machine set to 40 psi. It is a relieving regulator, but I suspect it isn't relieving very well. By...

Some more info: One of the reasons I suspect the air support is that the shudder seems to coincide with hearing air escape. While traveling down, when it gets near the bottom there will be a hiss of...

Hey folks,

I'm having an issue with my BP Series II with Centroid M40 Servo system. When I run a program, any time it goes to Z home (for tool change, for example) I get either a Z-position error...

Ahhh...interesting. Clearly I had the wrong idea of how this works. So the "override offsets" fields are looking for a tool number, not an actual offset, which is probably why it rounded it to the...

I have an old M-40 controller that doesn't appear to allow this.

My plan is to load each tool and touch off on the part and record the offset for each one from the longest tool. Then I'll enter...

Cool. So you have the ability to change the tool length in the program on the fly? I don't think my controller is setup to do that. Or have I just not found that functionality yet?

Hi Folks,

Cut my first CNC chips this weekend and feeling pretty stoked. I'm working with BobCad for Solidworks and using a Centroid controller. I haven't been able to figure out the best way to...
