hi
I sorted out the some problem i had with thc 300
it was that i was confused about post file in sheetcam(where i supposed to enter my switch travel)with the tap file resulted from sheetcam because in sheetcam i fave the "run postprocessor" button labelled with a green "P" letter.so i was thinking that the file where i have to insert the switch travel is the file resulted from clicking that button
i have now another problem :when i run the code in mach with the THC on the torch will dive in to the plate.
it does not happen if i turn of the THC
i have the following :
if the torch is siting on the plate and z = o jog the z axis up the dro increases (goes positive )
hit "z home " and the z axis goes down torch toches the plate z continues moving until trips the limit switch stops then lifts up a Little bit and zeros the z dro
i have set the THC delay in mach to 1.5
the THC300 front panel leds for up and down matches the screens up and down leds
i have changed in ports and pins the torch up , torch down from active low (box checked "v") to active hi (box unchecked "x" )
and the torch was getting lifted up allot so i did set them back to active low
the THC max is 30 the THC min is -30
if i start a job with coarse and fine coarse centred the fault led does not go of so i had to turn the coarse CCW to about 11 a clock
(if it was to be a analogue clock indicator )to get the fault led to go of
i have grounded the plasma (pwmax 1650) to a rod driven about 1.5 meter in the ground
my plasma table is 6.5/2.1 meters big so i fitted all electronics on the gantry to keep all the cables short not to risk any interferences but my material table is not electrically connected to my cnc table
so it should not be a problem
now what can by the problem that the torch dives in to the material during a 350 mm straight line ?
PS Tom i could not find the mp1000c manual on candcnc web page
