Ping Iggy. Advice needed. [Long]
Hi Iggy.
I inherited a year or two ago, a nice Shizuoka ST-N CNC mill. This is a 3-axis machine with a nice large CNC rotary table giving it a 4th axis. It was given to me by a good friend who couldn't fit it into his workshop. It has low hours and was only ever used for machining acrylic. This Japanese machine was originally sourced from and fitted out by a UK company, Matchmaker, who fitted an unknown control system with arm mounted CRT and button panel. The only thing we can easily recognise in the bird's nest that is inside the control cabinet is the 4qty, Westamp PWM servo amp model no. 30060-3. I take it that this means we have servos rather than steppers? This makes sense as they (large) motors have 4 brushes. I think they have 2-wire tachos built in too. I'm not sure what encoders we have yet as they haven't been stripped out for identification. The control system is dead. The CRT is dead, and I don't trust the Westamp boards. However we'd probably keep the big DC PSU, buy 4 new servo drives and fit a variable freq drive for the spindle. This brings me to the big question. What controller should we choose? We'd like to do as you have done, and use EMC2 on a (Linux?) PC, but don't have any idea of what controller we need for the 'bit in between'. I'd appreciate your advice on this if can spare a moment. Many thanks in advance. JB |

JB, you are on a good track. You have a great machine with a great 4th axis. The control is junk. You need to subscribe to emc-users mailing list at https://lists.sourceforge.net/lists/listinfo/emc-users Then you need to go slow and identify your hardware (what servos? What voltage and current?) Try to find a schematic of the mill, if you can, pre-retrofit. It will help you identify wires from all opints like limit switches, valves etc. What you want is certainly doable, will probably take a while, but can be done in steps where the result of each step is verified. For example, you can hook up one servo motor to one servo drive, and "drive" it by selding a signal from a battery to the niput of the servo drive. Try to identify your servos first. You may reuse things from the old control, such as relays, power supply, and possibly even servo drives. i |

I'm already on CNCZone. There is a good section on EMC there too. http://www.cnczone.com/forums/emc_li...chine_control/ I'll get the servos off later this week and check them out. Cheers, JB |

I'm in the process of building another trike. This one for my wife. A BMW K100 bike mated to (probably) a BMW E36 back axle. I have done a few and i've often cursed te lack of a CNC machine. Milling **** out by hand and doing all of the inevitable 'fettling' is a time consuming job. Much better to squirt the design over a DXf (I hope!). You may want to hate me again when i tell you about the machines we run at work. http://www.amada.com/site/default.as...emlk3610nt.htm and http://www.amada.co.jp/english/produ...nt_series.html Plus a few of these: http://www.salvagnini.com/salvagnini.php?s=291&new=1 and even some (8!) of these: http://www.vossloh-schwabe.com/image...200801_eng.pdf At work we really _do_ sheet metal. I'll keep you posted as to progress on the mill. Cheers. JB |

Yes ( brush DC, there is a tach on these that will most likely not be needed and there is an encoder like I say its probly 2500 per rev ) I'll try and reload the ubunto disc soon but IIRC its the basic NIST is all I really need here this will be a gang tool setup. ( "soon" to me sometimes takes a year or so just so you are aware ) Or it might be in just a few minutes...
