A little more information on what you are doing would be helpful such as cutter dia. work piece size and what kind cut you are trying to make. Are you using the frame mill function to surface?

Thanks, I will do that.

I guess I wasn't clear. The problem is that the Dolphin post processor does not do cutter compensation very well for my machine (Dynapath 20). I can machine on the profile but not offset left or...

Maybe I'm missing something, but when rescaling a drawing (which has multiple lines and arcs) using the select, cut, and paste method, the drawing loses its original orientation with respect to the...

I have Hurco cnc mill with a Dynapath 20 control. I run mine with a rotary phase converter that I got from quite likely the same guy you are talking about. It works fine although you need to...

I am not sure how you are trying to find the cavity mill function, but if you have a program called up and are in program mode, have a line number selected and then push the event type key, cavity...

There is one on E Bay. The price is steep though. It depends on how bad one wants one.

In the set up mode, you can set the Home Position. The program will send the machine to the home position coordinates and turn off the spindle (assuming the spindle is under program control) when...

That sounds good. How does one disable part surface programming? Thanks.

I am not exactly sure which version of Dynapath 20 I have. The mill its on is a mid 90's Hurco MHP. For EIA/ISO programming, the manual states only one G code per line. This is one of the problems...

My disclaimer, I have a lot of trouble with cutter comp too. That said, the Dynapath manual I have (under the G41 section) says that the diameter offset will only occurr in the selected plane (ie...

The phase converter I use is similar to yours. The thing about the Dynapath control (unlike some other cnc controls) is that it only uses the 3-phase to power the spindle motor and the rest of the...

When you wire the phase converter to the control you need to use care. Two of the legs of the 3 phase input power go to a transformer which converts the 220 volt input to 110 volt single phase to...

I have a Dynapath 20, but it ought to be smiliar. Your system is doing what mine did when the cable pin wiring was wrong. Have you been able to download to this machine from something other than...

I am also curious about the status of the Tormach lathe. I have been looking for an CNC lathe for my home shop for a while now. While there is a lot of used equipment available, I find the EMCO's...

Thanks for all the input. I've got a 50 amp circuit in my garage so it looks like I am good to go if I can just find the right machine.

I am trying to figure out if I can power a 7.5hp 3 phase CNC lathe in my home shop. I would like to use a VFD and have determined that the output maximum amperage for a 7.5 VFD is about 25 amps 3...

I have a Hurco with a Dynapath 20. I also use a rotary phase converter. When you wire the phase converter to your mill, the first thing you need to do is determine, at the point the power line...

Did you reference the machine first? I have a Dynapath 20 and you can't do anything until you reference it. On the screen you have displayed, hit R instead of a jog speed and follow the machines...

The light box (mine is called an RS232 mini-tester) will determine if a signal is getting to yourRS232 port when the PC is sending and if a signal is leaving the RS232 port when sending a program. I...

You might have a Kwik Switch spindle. One way to find out what you have is go to Tools-n-Gizmos: New and Used Surplus Machine Tooling. They have pictures and specifications for many different tool...

I wanted to thank everyone for their input. After reading everyone's input, doing some more research, and talking with Shop Floor Automation (where I bought the cable) and learning more about the...

The mill I have is a Hurco MHP 3K. It is one of the models Hurco put a Dynapath on instead of their own controls. I cheked the cable pinouts. The cable is a DB 9 to DB 25. On the DB 25, 6-8-20...

I have a mill with a Delta Dynapath 20 control. The control works and I have used the conversational programming feature to write programs. I am now trying to get the program load feature to work...

Thanks for the replies. I did overlook the topic on cutter comp in the appendix of the manual. That addresses lead in events. I'll go back and experiment some more.

I recently acquired a Hurco MHP-3K mill with a Dynapath 20 control. I have the manual and am learning to program it. For CAD/Cam I am currently using Dolphin CAD CAM and it has a post processor for...

I have an opportunity to purchase a knee mill with a Centroid M 15 control. By the serial number it appears to be at least 12 years old. Has anyone updated one of these controls or at least have...

I have a similar question so I will try this thread. I am considering the purchase of a Bridgeport mill with an older Anilam 2 axis CNC control. I would retrofit the mill with Mach 3. Is there a...

I am considering buying a Bridgeport with a 2 axis Anilam 1100 CNC control. The Z axis is manual but has a DRO which reads out on the CNC display. I would like to retrofit to Mach 3 and replace the...
