big problem. no up/down signals from thc to mach3.

[matin]

Dear Sir,

I have Blade runner controller and mach3 software . I have a problem .
Could you please help me about following problem.

Could you please tell me what cause to stop sending up/down signals
from digital torch height control to computer mach screen? (can not see any thc up /down activity on mach screen and THC dro is 0.00. All setting for mach is correct and I can see sometimes the up and down signals .

Is it possible, that was related to high cutting speed 350 IPM or high pierce and cut standoff distance or long pierce delay when I cutting gauge 20 steel. I use g04 p0 for pierce delay but in mach3 setting page thc delay was 1 and in cut profile thc delay was also 1. I feel long pierce delay but the code was g04 p0 .

Can I replace our long cat 5 cable with 3 feet length cat5e cable that we use in modems ?Is it better for noise issues ?

I will appreciate for your help.

Your not posting enough info so lets hear what plasma cutter you have...what you mean by THC DRO do you mean Z axis? Is your THC button lit up green? Did you try cutting anything else and does it work on other profiles? Are you running HYT-connect or the latest version of Sheetcam and what post are you using? Whos system is this (home built or bought?). Did you put the unit in test mode?

Are your plug ins actived correctly? CandCNC install does not activate the CCC.comxxxxx plugin so you will not get tip volts until that is activated and is your Mach 3 liscensed?
