Mori Seiki SL1H Oak Board Build

[martyscncgarage]

I'd record the machine pertinent parameters, (Screen Shots), copy the current CNCT directory, uninstall it using Windows Control Panel, and start from scratch with the correct PLC program.
What Tom says is possible if you are comfortable doing so. It isn't difficult.

Many Thanks to all who have answered my queries.

I'm not sure this is the right or wrong way, but last time i messed with changing PLC programs I did the following:
1) Open PLCInstaller (Its one of the executables that you download in the softward file)
2) Choose the appropriate plc out of the list.
3) click install. (You will be prompted to overwrite existing PLC
4) Accept
5) Start CNC12
6) update parameters from screenshots. (Marty's suggestion)

That seems to have worked ok for me. I haven't worked with the acorn board so I'm not sure if you have the option of using the PLC installer that is part for the ALLIN1 and OAK.

Hopefully will be using the acorn on the next project. (Bed Mill)

Tomorrow I have a friend who is more familiar with PLC programming coming over to see if we can work our way through some of the logic. Order off attack"
1) Chuck Clamp/unclamp (Hydraulic) Will be actuated with one of the single pole double throw relays
2) Tailstock ) Same as above
3) Footswitch for chuck
4) Turret (This one is going to take some more time.) I'm not sure if we know what we are in for yet, but will start with the existing plc programs that have turret options and go from there.

Keep plugging away.
You got me motivated to start putting my OAK DMM DYN4 system together for the Clausing Kondia knee mill purchased to upgrade the control and sell it on.

I haven't addressed/reviewed the VFD yet.

Currently have spindle encoder input but not sure what parameters to change to have the control read the encoder and show rpm on the display. The control is reading the encoder counts as I can see them accumulating on axis 6 but that doesn't translate to RPM at this time.

Did I miss a manual somewhere that goes through how to setup different types of items on the oak board? Seems I have to ask every time I make the next step and feel like this is simple stuff that many if not most machines that will use an oak board would want to integrate. Not sure if I just missed that manual or something. I don't want to be wasting your guys time if the information is hiding in plain site.

After that I need to look into if I wired up the vfd wrong or if I just don't have it in the correct mode to receive input from the oak board. I don't get any response from it when I try to interface. Output voltage from oak is correct. (Probably messed of the wiring. )

Thanks again!

Marty,

I'd be interested in what type of progress you make with the oak board and the DYN4. I've got axis motion now and its pretty good, but I still can't make it work without quadrature errors. I think your going to find the signal being sent from the dyn4 drive to the oak isn't perfect. I haven't pursued that issue any further yet. (I might never pursue it if it doesn't cause issues)

First Pic is what you get when you start running and the spindle is turning the wrong direction. (Tool is upside down in the turret)

Second pic is what you get when you turn the spindle the right way.

Got some PLC changes made tonight.

1) Chuck footswitch works now. (Safety line added so footswitch is not active when programs are running) (Still need to add m code functionality so i can bar pull)
2) X axis brake works now. (I needed/wanted the the double throw switch the tailstock.) (On second though probably could have used two relays instead oh well)
3) tailstock works now. (M24 extend M25 retract) Somewhat random choice on the mcodes. Googled it and it seemed like that varies from machine to machine. Will probably add that function to a switch at some point as well to make setups easier. (Will just use mdi for now.)

Pretty good win for the day. (Had help from a friend more familiar with programming.
Turret is probably the last thing we will tackle. Based on how tonight went I feeling pretty positive about our first gander into centroid plc editing.

I'd be interested in hearing (a list) of what safeties I should be adding into the plc program to prevent unplanned unsafe conditions. This machine is definitely big enough to cause damage. The lathe that is sitting across from it is 25HP with gearbox and would eat you and spit you out and barely register on the load meter.

Why not use an acorn for this upgrade?

The reason I ask is because I have a bed mill next on my to do list and intended to go Acorn. On the list behind that is a Mori SL2B and if the expansion board comes out I'm hoping to go acorn with that too. (Some day down the road I'd like a tool room lathe with an acorn control too.)

Probably talking a couple years before I get to all three, but i'm curious once the expansion board comes out what would be the primary advantages between acorn and oak for a machine that only needed enough I/O such that either could be used?

Because I want to prove the OAK/DMM combination for myself and demonstrate it on a couple of videos.
Backpanel is about done. Another half day or so and it will be wired, ready to benchtest DMM DYN4 and AC Servos before mounting them up to the mill.

You are correct, Acorn could run this mill.

That is super Marty. Your answer exactly what I was hoping to hear.

1) I was hoping to use the acorn for my bed mill as mentioned,
2) I really would like to be able to use my dyn4 with the oak as is. (Currently still hiding the quadrature errors)

You can use Acorn for your bed mill. I assume you will use DYN4? If so, buy the DMM DYN4 to Acorn flying lead cables.

I will let you (and everyone else know) how the benchtest goes.
