Fanuc-Style Toolchange

Category: Advanced Configuration

Hello gentelmen,

how is it with the manual tool change... 

I have sometime issue with precision after tool change +-0.01mm with OWT grinded tool post fixtures with manual toolchange .hal stuff.. I noticed that in the default tool table for lathe is not the waer offsets .. I can switch on them by
LATHE_WEAR_OFFSETS = 1

where I can define them for the each tool separately 

And then add the the remapping ?

Then I will need to change T1 G43 to T01XX in the postprocessor I think ..

Thanks,

Regards

HURCO KMB-1 Control Update

Category: Milling Machines

I'm still addressing some old school electronics that needed updating in the VFD, so turned my attention back to the override potentiometers.
When the spindle runs and I read the pot via the 3.3volt Analogue pin 7i92.0.7i71.0.2.input_03, there is a notable hunting in the spindle speed. Not much, but it just doesn't sound steady.
This is down I think to the ADC hopping between bits which is also normal.
I looked at the original Hurco control use of the pots and how the analogue values were read, and note that the conversion to digital was done in a 12 bit ADC. so the increment between bits is tiny in comparison.
In the 7i73 manual. it states:
"OPERATION
ANALOG INPUTS
Inputs 0 through 7 can read analog signal values however only inputs 0 through 3 are supported for analog input by available interface modes. Analog inputs have a range of 0 to 3.3V. Normal resolution is 8 bits. All bits are readable as digital inputs. Note: analog inputs are only accessible in some software modes."

Does this mean I could configure an analogue input to use a increased resolution of 12 bits?
If so How would I do that?
Thanks

Leadshine EL7-EC400N ethercat error 818

Category: EtherCAT

Hello everyone,
I'm new to the forum, I just bought two Leadshine EL7-EC400N ethercat driver servo with Leadshine ELM1 AC servo motor 400W to start my new cnc projects.
I installed linuxcnc-ethercat following @Rodw's Ethercat installation from repositories documentation and i created a .ini config lithe axis with two axis X Z, and a hal file and ethercath-conf.xml, but every time I start linuxcnc I get an error 818,
My question is whether the Leadshine EL7-EC400N is compatible with linuxcnc or not?
and also I'm wondering if there's anyone who can help me or give me a minimum configuration (.ini, .hal, .xml) file to make the motor start and get past error 818?
I used rodw's configuration

not sure what you mean by "the position marker's start". A screenshot with an arrow might give us a clearer picture of what you are trying to achieve.

LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

here i can also show the structure of the frames or the rio.v:

this is the 'top' verilog module, the main module:

github.com/multigcs/riocore/blob/dev/doc...ngbob/Gateware/rio.v

there is a block in which the RX frames are split into individual 'output signals':
    // PC -> FPGA (330 + FILL)
    // assign header_rx = {rx_data[327:320], rx_data[335:328], rx_data[343:336], rx_data[351:344]};
    assign VAROUT128_MODBUS0_TXDATA = {rx_data[199:192], rx_data[207:200], rx_data[215:208], rx_data[223:216], rx_data[231:224], rx_data[239:232], rx_data[247:240], rx_data[255:248], rx_data[263:256], rx_data[271:264], rx_data[279:272], rx_data[287:280], rx_data[295:288], rx_data[303:296], rx_data[311:304], rx_data[319:312]};
    assign VAROUT32_PWMOUT0_DTY = {rx_data[167:160], rx_data[175:168], rx_data[183:176], rx_data[191:184]};
    assign VAROUT32_STEPDIR0_VELOCITY = {rx_data[135:128], rx_data[143:136], rx_data[151:144], rx_data[159:152]};
    assign VAROUT32_STEPDIR1_VELOCITY = {rx_data[103:96], rx_data[111:104], rx_data[119:112], rx_data[127:120]};
    assign VAROUT32_STEPDIR2_VELOCITY = {rx_data[71:64], rx_data[79:72], rx_data[87:80], rx_data[95:88]};
    assign VAROUT32_STEPDIR3_VELOCITY = {rx_data[39:32], rx_data[47:40], rx_data[55:48], rx_data[63:56]};
    assign VAROUT1_WLED0_0_GREEN = {rx_data[31]};
    assign VAROUT1_WLED0_0_BLUE = {rx_data[30]};
    assign VAROUT1_WLED0_0_RED = {rx_data[29]};
    assign VAROUT1_BITOUT0_BIT = {rx_data[28]};
    assign VAROUT1_BITOUT1_BIT = {rx_data[27]};
    assign VAROUT1_PWMOUT0_ENABLE = {rx_data[26]};
    assign VAROUT1_STEPDIR0_ENABLE = {rx_data[25]};
    assign VAROUT1_STEPDIR1_ENABLE = {rx_data[24]};
    assign VAROUT1_STEPDIR2_ENABLE = {rx_data[23]};
    assign VAROUT1_STEPDIR3_ENABLE = {rx_data[22]};
    // assign FILL = rx_data[21:0];

and a block in which the ‘input signals’ are assembled to the TX frame:
    // FPGA -> PC (349 + FILL)
    assign tx_data = {
        header_tx[7:0], header_tx[15:8], header_tx[23:16], header_tx[31:24],
        timestamp[7:0], timestamp[15:8], timestamp[23:16], timestamp[31:24],
        MULTIPLEXED_INPUT_VALUE[7:0], MULTIPLEXED_INPUT_VALUE[15:8],
        MULTIPLEXED_INPUT_ID[7:0],
        VARIN128_MODBUS0_RXDATA[7:0], VARIN128_MODBUS0_RXDATA[15:8], VARIN128_MODBUS0_RXDATA[23:16], VARIN128_MODBUS0_RXDATA[31:24], VARIN128_MODBUS0_RXDATA[39:32], VARIN128_MODBUS0_RXDATA[47:40], VARIN128_MODBUS0_RXDATA[55:48], VARIN128_MODBUS0_RXDATA[63:56], VARIN128_MODBUS0_RXDATA[71:64], VARIN128_MODBUS0_RXDATA[79:72], VARIN128_MODBUS0_RXDATA[87:80], VARIN128_MODBUS0_RXDATA[95:88], VARIN128_MODBUS0_RXDATA[103:96], VARIN128_MODBUS0_RXDATA[111:104], VARIN128_MODBUS0_RXDATA[119:112], VARIN128_MODBUS0_RXDATA[127:120],
        VARIN32_STEPDIR0_POSITION[7:0], VARIN32_STEPDIR0_POSITION[15:8], VARIN32_STEPDIR0_POSITION[23:16], VARIN32_STEPDIR0_POSITION[31:24],
        VARIN32_STEPDIR1_POSITION[7:0], VARIN32_STEPDIR1_POSITION[15:8], VARIN32_STEPDIR1_POSITION[23:16], VARIN32_STEPDIR1_POSITION[31:24],
        VARIN32_STEPDIR2_POSITION[7:0], VARIN32_STEPDIR2_POSITION[15:8], VARIN32_STEPDIR2_POSITION[23:16], VARIN32_STEPDIR2_POSITION[31:24],
        VARIN32_STEPDIR3_POSITION[7:0], VARIN32_STEPDIR3_POSITION[15:8], VARIN32_STEPDIR3_POSITION[23:16], VARIN32_STEPDIR3_POSITION[31:24],
        VARIN1_BITIN0_BIT,
        VARIN1_BITIN1_BIT,
        VARIN1_BITIN2_BIT,
        VARIN1_BITIN3_BIT,
        VARIN1_BITIN4_BIT,
        3'd0
    };
    

in the case of the Tangbob, the two frames ‘rx_data’ and ‘tx_data’ are passed to the w5500 module, which then takes care of the data exchange with the host computer:
    w5500 #(
        .MAC_ADDR({8'hAA, 8'hAF, 8'hFA, 8'hCC, 8'hE3, 8'h1C}),
        .IP_ADDR({8'd192, 8'd168, 8'd10, 8'd194}),
        .NET_MASK({8'd255, 8'd255, 8'd255, 8'd0}),
        .GW_ADDR({8'd192, 8'd168, 8'd10, 8'd1}),
        .PORT(2390),
        .BUFFER_SIZE(BUFFER_SIZE),
        .MSGID(32'h74697277),
        .DIVIDER(0)
    ) w55000 (
        .clk(sysclk),
        .mosi(PINOUT_W55000_MOSI_RAW),
        .miso(PININ_W55000_MISO),
        .sclk(PINOUT_W55000_SCLK_RAW),
        .sel(PINOUT_W55000_SEL_RAW),
        .intr(1'd0),
        .rx_data(rx_data),
        .tx_data(tx_data),
        .sync(INTERFACE_SYNC)
    );

Now let's take a look at the signals from one of the Stepdir module instances:

the input/output signals have the following naming scheme: VAR[DIRECTION][SIZE]_[MODULE_INSTANCE]_[SIGNALNAME]

* VAROUT32_STEPDIR0_VELOCITY : a 32 bit output value for the specified velocity (steprate)
* VAROUT1_STEPDIR0_ENABLE : a 1 bit output value to activate the stepper (enable signal)
* VARIN32_STEPDIR0_POSITION : a 32 bit input value to return the current position (step counter)

    stepdir #(
        .PULSE_LEN(108),
        .DIR_DELAY(18)
    ) stepdir0 (
        .clk(sysclk),
        .step(PINOUT_STEPDIR0_STEP_RAW),
        .dir(PINOUT_STEPDIR0_DIR_RAW),
        .velocity(VAROUT32_STEPDIR0_VELOCITY),
        .enable(VAROUT1_STEPDIR0_ENABLE & ~ERROR),
        .position(VARIN32_STEPDIR0_POSITION)
    );


the pin signals have the following naming scheme: PIN[DIRECTION]_[MODULE_INSTANCE]_[PINNAME]

however, they can also have suffixes, such as. _RAW / _INVERTED / _DEBOUNCED / ...
this is due to the modifiers pipeline that can be configured for each pin.

Errors when searching for axis origins

Category: General LinuxCNC Questions

Hi guys, I have a question, when I turn on LinuxCNC drivers with absolute encoders, they make a delay to search for the machine zeros, accordingly, if I turn on the CNC before they find the beginning, a bunch of errors appear, is it possible to make some kind of delay when turning on until the driver finds the beginning? thanks

Do I need a better PC?

Category: EtherCAT

ok, sometimes when I run my Ethercat servos, they sound like they have bad bearings/run rough. Restarting linuxcnc sometimes solves it and they run buttery smooth. I've also gotten a warning unexpected realtime delay. Im guessing Its because Im running the cheapest HP pavilion desktop junk(runs off a little wall wart and has the smallest cooling fan on a 1x1" cpu heat sink. :D
Anything I should look for when buying a proper motherboard for ethercat linuxcnc?

well I reRan lcec_configgen and got a different reading on slave IDX 2 not sure why. I was able to fart around with the XML and get the servo going. it about jumped off my bench. she's a ripper.

Category: Basic Configuration

I believe I have just about everything I need figured out on our double gang grinder CNC lathe conversion as far as operation goes.. The only thing I have yet to figure is altering the position of the where the marker starts on the preview grid. I would really like to have the plot marker in preview to be in the middle of the X on the grid. Tool offset and home offset have had zero change to the position marker's start on the grid. 
Thanks in advance.

Hi, I work as a CNC Plasma Beam line Operator and any time I change consumables I have to reset the number of hit of the plasma to zero and as is cutting it count the number of hit, and know how long the consumables last and to change them can't we do the same thing to QtPlasmaC.

It does make the resolution of the encoder frequency  a bit better than at 1 ms
but the periodm does not care as you specify the number of period averages.
