Re: EMCO F3-CNC

I have not seen any info on the F3-CNC, but the Emcotronic control system is also used on several other system, for example, the Emco F1P (not regular F1), VMC100, and the compact 6 and EmcoTurn 120 lathe.


Look at the document section here as well as in the "emco_turn_120" and "emcof1mill" groups and you will find lots of schematics and information on the Emcotronic control system.


If you look at this, it will be fairly straightforward to understand how the F3 works.

Re: G84 cycle on mark3 Emco

m.wg@...
 

Hi Daniel


You have identified the difference in your question. When G84 is used on later Mk's of machine there is an additional column, this is marked H and as you say provides multiple passes to the cycle. The depth of cut required is entered into the H column and the control panel computes the final cut if the total depth of cut in X is not exactly divisable by the dimension in H.

If entered in MFI you will see in the Comments column the number of passes per cycle.

On the Mk2 machine G84 is 1 longitudal cycle so the dimension in the X column is the depth of cut for the cycle. This does save entering 3 additional lines of code to achieve the same movement of the tool.

On both machines after using G84 the tool finishes at the start of cycle position.

G84 cycle on mark3 Emco

Hi guys,

does anyone have the G-Code description for the mark 3? Only find the mark 4 ones - in them, the G84 cycle is described as a longitudinal cycle which cuts several times and uses more parameters.
If I switch in MFI editor to Mark 2 and use G84, it's only X, Z and F. So I wonder what this cycle does.

Daniel

This should be cheaper than converting it to A6C114004 (it's a 4003 if I checked the EEPROMs correctly).

Thanks guys, this will keep me thinking when I manually change tools whether the build is worth it.
Again thanks!

EMCO F3-CNC

fgg df
 

Hello,
I'm working on changing controll on F3-CNC emco machine (EMCO Tronic M1). Axis and spindle driver will stay original, i will just make custom communication interface, that plugs in existing bus. I plan to make interface using Xilinx FPGA chip (Spartan 6). Since i'm new to FPGA technology this might take a while :)
If someone has electical schematics from this type of machine, i would appriciate if one can upload. You would save me a lot of time! In exchange i will share this project with this group and make it open source if i can.
Thanks and best regards,
Uroš

Hi Daniël,

I don't have any plans for the tool changer, but it's really simple, maybe someone can make some photos of it.
I'm using the stock tool changer with a stepper motor on it. Works like a charm.

Now I'm thinking about it I must have some plans somewhere in my desktop pc. But I'll have to search for it, because I have no idea where it's stored in my pc.

Anyways, good luck searching for information. I hope someone else Van help you out better than I do.

Regards,

Peter

Hi all,

I will get my Emco Compact 5 CNC tomorrow - oh joy! However it doesn't have a automatic tool changer. Now I can find that there was a posting with plans for a DIY build of an automated toolchanger - but can't find them.

Can you help me out?

compact 5 f1

diego agudelo <diego.agudelo@...>
 

good friends. I got the documents along with the machines (compact 5 f1) is the service manual. observing it in detail the console or box where the different cards this original. A6A 116001 - 112001 A6A - A6C114003-A6A113001-A6A115010. refers to the manual interface and DNC. in Chapter 7.3 to 7.35. dnc handling this better would put the machine depending on the version. I own the machines are with floppy. I am testing the interface but I can not get the connection between pc and engines

Re: Compact5 CNC Identification

Depends on which spindle control switch is fitted to your lathe. There is a live mains voltage AC wire to the common  side of a NO (normally open) pair of contacts, this linked to the other Common terminal so there are 2 sets of contacts working in parallel. 

Then when you operate M03,and the relay energises, a cable from the linked NO contacts is the live AC feed to the Motor Control Board to start the spindle.

Basically the relay is in parallel with the switch so either will start the spindle regardless of position of the other device.

If you have the latest 3 position NVR switch fitted check the schematic drawing for further information, probably best to do that in any case as the CIRCUIT WE ARE DISCUSSING IS AT MAINS POTENTIAL SO BE SAFE AND REMOVE PLUG FROM POWER SOCKET BEFORE WORKING IN THE PANEL.

Thanks for info.


Where goes 2-3 black wire on connector next to socket relay?  I've not this connector with wires.


I've tried some threading code and it seem to work as is.  So I will not disassemble sensor.  


Thanks

Re: Compact5 CNC Identification

m.wg@...
 

Check in the Photo section for my picture file, just added some pics of the relay so you can get the type needed. it is a DPCO with 12V DC coil and contacts rated at 10A 230v .

Wiring is shown in the picture. You will know if your wiring is complete because you can view the Red LED's operating when you try to use M03 to start and M05 to stop the spindle.

This DNC board only starts and stops the spindle motor, it doesn't change the speed of the spindle on the standard set-up, speed is still set by the pot on the control panel.


If you change the position of the speed sensor device be sure to get it back exactly correct or you may lose ability to thread. Best check the threading works before loosening the sensor screws, if it works OK and spindle rpm is recording my advice would be to leave well alone, if it aint broke why fix it ?

Re: Compact5 CNC Identification

Hi Marcus.


I have DNC board with relay socket but no relay in it.  Unfortunately it has not fallen to the bottom.  Does it only need relay and wire to make work m03 ? Will this control variable speed also?  I've check a bit on ebay but didnt find.


I have resolve my rs232 communication problem.  It was usb adaptor.  I've tried with an old laptop with native serial db9 and it work like a charm.


Do you have any idea how to clean keypad?  It is not working fine.  It miss key or enter twice value.  Hardware store sell me brake and electric cleaner.  It is written "clean electric contact and dissolve oil, protect rubber contact of the cleaner and try plastic on smaller area before use." 


I would like to clean photo sensor and perforate disc too but im not sure if this cleaner is too strong.


Thanks

Re: Compact5 CNC Identification

m.wg@...
 

Hi

Check in this picture to see the DNC pcb, look at E6 and you see the relay socket, that's the relay controlled by M03 command, if you don't have the DNC board fitted then M03 has no function. Perhaps the relay is in the bottom of the cabinet, there is no retaining clip.!!!!!!

I have the 2 position white switch to start spindle. m03 m04 is read when running program but have no effect.

You should open your own post, it will be more easy to other member to help us with our specific problem.  It is difficult to navigate this site compared to common forum but this groups contain a lot of information and search function is the best way i found to find what i need.  Unfortunately i have to ask to group help because i have not find answer to my identification question.

thanks friend. indeed in the area where I live there is not much familiarity with these components and I do not handle this well!. and I think this is becoming a problem. I describe my situation: I try to use the interface but I could not adjust it, then put it together I saw the rs232, but I am using a mach 3 and I have to set the pins, I'm doing this with a friend who manages the party system. we have 5 lathes compact five and two f1. if you could share a document I would be helpful. once again thank you very much.
