I had some issues where this was a bit forgetful and forgot to turn the probe off when retracting so this does a bit more checking. Seems OK now after cutting a full sheet.
@Rod
So I helped a friend update to this today. He updated his <machine>_connections.hal file to change it to ohmic3. He says that ohmic probing doesn't work at all now. I am not sure why it wouldn't, so I had him switch back to ohmic2, which does work.
Any thoughts? At first, I thought that maybe his thresholds needed tweaking, but why would ohmic2 work and not ohmic3?
Another question I had, looking at the comp file, all of the pins get assigned values. I assume this gets overridden because Halscope did show my values, but I was wondering why they get hard set in here:
Code:
// Example Calibration Data: 0v = 122.9 kHz, 10v = 925.7 Khz should be entered as 122900 and 925700
pin in float thcad_0_volt_freq "0 volt calibration data for THCAD card in Hz";
pin in float thcad_max_volt_freq "Full scale calibration data for THCAD Card in Hz";
pin in float thcad_divide = 32 "THCAD Divider set by links on THCAD board (1,32,64 or 128";
pin in float thcad_fullscale = 5 "THCAD Fullscale (5, 10 or 300)";
pin in float velocity_in "The velocity returned from the THCAD and read by the Mesa encoder input";
pin in float volt_divider = 4.9 "The divide ratio (default 1:1)";
pin in float ohmic_threshold = 18 "The threshold volts above which Ohmic sensing is set to be true";
pin in float ohmic_low = 5 "The threshold volts below which Ohmic sensing is set to be false";
pin out bit arc_on "True if full scale (eg arc is on)";
pin out float thcad_volts "Measured thcad voltage";
pin out float ohmic_volts "Calculated Ohmic voltage";
pin out bit ohmic_on "Threshold plasma torch voltage";
pin in bit is_probing "True if probing";
pin in s32 motion_type_in "Connect motion.motion-type here";
pin out bit power_on "Turn relay on with this pin";
pin in s32 mode = 0 "0 = use low threshold, 1 = use trend";
pin in s32 num_readings = 5 "number of servo cycles to stay on trend";
pin out float dbg_avgv "average arc volts";
function _;
