Re: List of available THCs?

I am sure the vast majority of the PS users have little or no interest in the discussion of PID theory, A-D conversion or engineering talk. Its like standign and listening to two Doctors talk in medical terms. I am punching out of this thread. All I have to say, is get past the theory and the "...

Re: List of available THCs?

I made my own version of the Mesa THCAD and it worked great. However, my sample rate was too low at 62 times/sec. What got me interested in the THCAD ?? Well, in the beginning it was simply that it was an easy interface method all ready to go. When I got the board I checked out the components and th...

Re: Not cutting through once cut is started- Powermax 125

Regarding lean/angularity in cuts. Many users have had this issue, myself included. I have a Powermax 1250 and replaced all the consumables yet still I got the lean in one direction. Slowing the feedrate seemed to help a bit. Anyway, it seems for a few users, that particular issue has been miraculou...

Re: Anyone running UCCNC?

I'm noticing that on the PC screen in demo mode (no board connected, just doing test stuff). I can visibly see the toolpoint slow down before corners and speed up after them. However, this is just a fresh demo install without touching any settings. The accel/decel default settings may be down really...

Re: Floating Head Post Code

The post processor you used will produce a good G-code but is it compatible with your electronics package, if you look in SheetCam you will see there are a great number of post processors. Acourtjester, once again, this is taking the "black box" approach to things, i.e. finding a post pro...

What matters next is if Mach3 responds correctly to the individual gcode commands. Understand the gcode ...

Re: Is Initial Height Sensing Necessary?

Hope you did your homework regarding using ball screws on a plasma table. Depending on your max speed and table length you could get whipping of the leadscrew. Imagine you start off with your slats perfectly flat and parallel to the X and Y axis, then theoretically you wouldn't need initial height s...

Torch on timing question for Jim Colt.

Hi Jim, got another weird technical question that I'm guessing you don't get asked every day. I'll consider myself lucky if you know the answer to this one. Does Hypertherm have any timing specs that show how long the "delay" is from when the plasma cutter receives the TORCH ON signal from...

Re: help understanding whats going on in cuts

I think what's happening is the air is not flowing on the first pierce, there is a slight delay because of this, so the pierce is blowing a hole thru the thin metal, the hole gets bigger quicker in thin metal, causing the plasma cutter itself to shut off the arc. On the 2nd cut the air is still flo...

Re: help understanding whats going on in cuts

The problem is not a problem if yoou have a THC that uses an arc ok. That waits until there is a valid arc before it starts moving. The pierce delay, the plunge rate and the heights all play a role It takes the plasma longer to fire the torch if purge air is not on (that is not a function of the so...

Re: help understanding whats going on in cuts

Just a sidenote on troubleshooting. Many people treat the plasma setup as somewhat of a black box and don't bother to learn gcode. I advice not to be that way because it really helps you out when you can just glance at the gcode and see something obviously wrong, or if the problem lies elsewhere. Up...
