Re: Best budget minded THC for thin corrugated steel?

The quoted numbers are meaningless. The MiniTHC uses the same exact method as the Promo and several other cheap THC's in its methods. They send discrete Up and DOWN signals (the speed at which they do that is mostly irrelevant ) to MACH, and MACH reads them on a parallel port input and through IT'S ...

Re: Jerking motion and slow down while cutting

Observation is your best tool Its important to watch the Z DRO a the end of a cut when this is happening. It is supposed to lift UP from the G-Code to rapid height/ If its going down and the DRO shows it going down something is telling it to move in that direction. If its going down and the Z dro is...

Re: Jerking motion and slow down while cutting

When your torch ends the cut look at the Z DRO. (Feedhold if you have to and measure) Is it where the TORCH actually is? Do you have a touch off sensor? The motion under THC on a MACH3 based THC can result in lost steps if the THC Rate is too high or the Z itself is tuned too hot for the Z's ability...

Re: Best budget minded THC for thin corrugated steel?

Is the Proma the THC used by Burntables? No. Is a PLC they found that uses a pot and has no readouts and no user volts feedback or pre-sets . You twist the pot until you get the height you want. It does not have a range wide enough to use Fine Cut. Never at any point has BT used CandCNC electronics...

Re: Best budget minded THC for thin corrugated steel?

To even have a chance to work on corrugated you have to have a THC that has a vertical speed (under THC control) the same as your horizontal cut speeds. So if you want to cut at 400 IPM you need the Z to climb at 400IPM (45 deg slope) or it will plow into the material and drag it along the table. It...

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 sof...

Re: Help...need a finer detail plasma.

The guy down the street may not be using plasma. Really fine lines could be water jet or even laser cut. There is a finite kerf width when you are cutting with a 30,000 deg arc and blowing it out with shop air.

Re: poor cut quality

MACH CV lets the machine "fudge" the toolpath to get as high a Constant Velocity as it can. So you get rounded corners. The first thing is that you need to get as much ACCELERATION on the motor tuning as it can take. The faster you cut the more acceleration you need. Of course its limited ...

Re: Corner slowdown rules...do you use them for art, or just dimensional stuff?

Corner slowdown is only needed if the corners are getting rounded or have flat sections on an arc or circle. The CV actions in MACH favor speed (velocity) over tracking (following the toolpath) . What you do when you lower feedrate is you pull back the amount of acceleration you need to make a corne...
