    EMCO F1 CNC with TC55H controller

    Hi guys, I retrofitted my EMCO F1 CNC with Nema 23 steppers, M542 drivers and TC55H controller.

    I have to say that the system works flawlessly, should have done that many years ago.
    It feels like working with a complete new machine.
    The only thing I cannot get to work yet is subroutine programming.

    I tried the following:

    Program 0021

    N010 90
    N020 G0 Y19.5 Z-9
    N030 M3
    N040 G1 Z-10 F39
    N050 G20 N2101.3
    N060 G91
    N070 G22 N2101
    N080 G1 Z-0.5 F39
    N090 G24
    N100 M5
    N110 G90
    N120 G0 Z0
    N130 G0 Y0
    N140 M30

    (sub) Program 2101

    N020 G1 Y0.5 F249
    N030 G1 X-0.3
    N040 G3 X-0.2 Y-0.2 R0.2
    N050 G1 Y-16.1
    N060 G3 X0.2 Y-0.2 R0.2
    N070 G1 X0.6
    N080 G3 X0.2 Y0.2 R0.2
    N090 0 G1 Y16.1 F299
    N100 G3 X-0.2 Y0.2 R0.2
    N110 G1 X-0.3
    N120 G0 Y-0.50

    And I also tried this:

    N010 90
    N020 G0 Z-9
    N030 G1 Z-10 F149
    N040 M98 P090 L3
    N050 G90
    N060 G0 Z0
    N070 M30
    N080
    N090 G91
    N100 G1 Z-0.5 F39
    N110 Y5 F249
    N120 G3 Y-10 R5 F249
    N130 G3 Y10 R5
    N140 G0 Y-5
    N150 M17

    But it doesn't work..
    Anyone can advise how I can use subroutine in my Mach4 controller TC55H?
    Your help is very much appreciated.

    ...M98 Pxxxx to call subprogram and use M99 at the end of subprogram. Read more about it on Page 57-59

    Hi Machineshop5, thanks for the link with the MACH manual, really appreciated.
    The problem is ... I can only store programs with 4 digit numbers as file name on the TC55H controller.
    Then they are stored starting with a letter P followed by the 4 digits and I cannot store a program starting with the letter O.

    I tried also the option with the subprogram inside the main program like this:

    N010 G90
    N020 G0 Z-9
    N030 G1 Z-10 F149
    N040 M98 P1000 L5
    N050 G90
    N060 G0 Z0
    N070 M30
    N080
    N090 O1000
    N100 G91
    N110 G1 Z-1 F49
    N120 Y10
    N130 G3 Y-20 R10 F99
    N140 G3 Y20 R10
    N150 G0 Y0
    N160 M99

    But I get a message: "Illegal characters in line 4".

    Re: EMCO F1 CNC with TC55H controller

    I started reading the TC55H manual and after sparring with a friend I found the solution that works:

    N010 G90
    N020 G0 Z-9
    N030 G1 Z-10 F149
    N040 G20 N110.3
    N050 G22
    N060 G24
    N070 G90
    N080 G0 Z0
    N090 M30
    N100
    N110 G91
    N120 G1 Z-1 F49
    N130 Y10
    N140 G3 Y-20 R10 F99
    N150 G3 Y20 R10
    N160 G0 Y0
    N170 M99

    So happy that it works, I will use this format a lot for sure.

    Anyone familiar with generating G-code for the TC55H with a CAM module from Solidworks?
    That would be even easier, especially for complex product contours.
    Any help or experience sharing is appreciated.
