Re: CNC Knee Mill Control Conversion

I bought their encoder cable and power cable. I have the part numbers. Nothing special, most of their dealers don't buy the cable from them either. I have used Cat6E stranded for encoder cable. 14 gauge shielded with drain wire works well for power wire. Never again will I buy their cable. :-) I hop...

Re: CNC Knee Mill Control Conversion

I think you will be quite pleased with your choice. Have you had a chance to check out my YouTube channel, documenting my conversion using the All in One DC? martyscncgarage http://www.automation4less.com/encoders.htm is a good resource for encoders. You can contact them with your needs. Most times ...

Re: Controller conversions for a 1991 HAAS VF-1?

I won't describe the nightmare a customer who had a ***** machine that attempted to change a tool at 4000 RPM. called me up and blamed my software.... duh...like....M6 is M6 -> what else would you like me to do? Suggest you call the machine manufacturer and ask them. It turned out to be an interrup...

Re: Controller conversions for a 1991 HAAS VF-1?

After reading your inputs, we went back to the folks that donated the mill to us and they are going to have their chief machinist come out to help us restore the mill to working order or at least as close as we can get. It does not appear the conversion to a different controller is in the cards for...

Re: Controller conversions for a 1991 HAAS VF-1?

Did a search of 1991 VF-1 ATC and came up with this: http://www.practicalmachinist.com/vb/haas/91-haas-vf-1-drops-tools-atc-issues-234568/ You need to find out what exactly the problem is with the ATC. Thorough cleaning, inspection and doing a bunch of tool changes is in order. Like was mentioned, m...

Re: Ball Screw Question

Steve, If you are missing steps the measurements you take should not repeat! Lost steps should give you random readings... Of course there is also backlash issues, loose thrust bearings, bad (cheap) ball nuts and all that stuff. Without seeing some of the parts and the setup I can't really offer mu...

Re: Controller conversions for a 1991 HAAS VF-1?

Centroid CNC. Industrial control. PLC built in for the ATC. Likely Brushed DC servos on your machine. All in One DC would be the choice. I would NOT use Mach on this. Furthermore, doing a conversion like this is not for the faint of heart. Moving the axis is the easy part. Spindle orient, ATC, integ...

Re: CNC Knee Mill Control Conversion

Marty, I'm a big fan of the Centroid CNC stuff as well. I don't own any of it yet but I've been watching their product and videos for the last 8 years or so. I get the same feeling about dealing with one company who has both the software and the hardware. I don't have a machine worthy of putting Ce...

Re: CNC Knee Mill Control Conversion

By the way, if the motors you got are AC servos and Amplifiers, then Centroid OAK board might have been a good alternative (depending on communications to the amplifiers). It is less expensive than the All in One DC because the amplifiers are not needed.

Re: CNC Knee Mill Control Conversion

My motors had tachometers. Fortunately they were fairly easy to remove and replace with encoders. I am not putting an encoder on my spindle at this time. It's pretty difficult to do on a Bridgeport type head. I too have a VFD. Easily controlled by the Centroid all In One DC. Pictures here would be g...

Re: CNC Knee Mill Control Conversion

Marty, thank you for the input on the Centroid CNC. Mike (RRSC) and I were looking at this for a Bridgeport conversion. But, he bought a late '70,s Bridgeport Interact I for cheap and the machine hadn't seen much use. I currently building a new control system for it using Delta Servos, Vital DSPMC/...
