MAch 3 THC question

jeepsr4ever

Did you press enter after you put in the change? Did you apply and save your changes? Sometimes changes require a mach 3 restart.

Yes i pressed enter, it had saved before but for some reason it went back to 1 inch. The reason i checked it was because it raised the torch .20 and i had the max set on .12 i was just trying to stop it from raising too far till i get the thc figured out. I was looking around and i found this driver problem maybe it could be the problem but i am not sure.

Not quite understanding your problem with Mach. Your trying to raise it from your program in mach and not in sheetcam?

I am talking about the limits in mach 3 under settings its raising the torch to high during cutting when using the THC when it decides to move. THe problem with mach 3 is the THC doensn' t work for me.LOL

Are you saying for the initial touch off then raise to pierce? Those settings are in your tool settings in sheetcam. If your problem is the Z moves too high that is almost always a tip volt too small or the reading is wrong. I canmost likely help you iron this out 100% I just need to know when the problem occurs.

Oh no that works just great no problem with sheetcam that is all working fine. I am talking about when its cutting the THC will raise .20 and never go down and that will cause it not to cut all the way through the metal. Its not moving the torch up or down like it should. Its reading the voltage on the screen but doesnt move the torch hardly at all. IT should be cutting at 116 according to the book but the actual volts will go up and down +or - 20 volts but the THC doesn't react to correct the cut height. Sometimes it will move the torch up but thats it, it seems like mach isnt sending the signals to move up or down according to the voltage its reading.

What number is your antidive set at?

Hmm it could be that plug in. Contact Tom and CandCNC and see what he says about it. My guess is that the conflict will cause the issue.

I sent an email to tom. I did the test feature on the electronics box and i am getting the test voltage of 100 then 150 and the up and down lights light up as the voltage changes. I am not sure if this could be a problem but when i do the test for the THc the up and down leds blink 3 times instead of 5 times.

Defiantely something to do with either the PC or THC. A problem where THC is not responding like you mentioned usually has everything to do with the PC. You have two Bulltear gantry kits there are you using one PC? If not try the other one.
