Thanks!
I appreciate the reply. I will try to delay the air and maybe find a sweet spot there. We also tried less than 1 bar O2 and the cut is still fine.

Hello all,

We purchased a laser tubing cutter with a Raycus 500 watt generator and Raytools head. We are cutting .065" wall tubing at a rate of about 60 IPM.

We have been faced with multiple...

This is all very helpful, I like the idea of the manual foot.

I'll start the search for components and may have more questions later, thanks!

Thanks for all the info!

So, it sounds necessary to have Z axis for accurate standoff.

On the pierce mark, any guess of how deep it will average?

Is there a short list of basic...

I really appreciate any and all advice! Yes, my plans to rotate the part lean toward a lathe spindle head with air chuck. Rotation could be a fairly small variable speed drive. I can rig an easy feed...

I'm looking at laser as an alternative to cold saw. The length of cut is +/_ .007", and only needs deburr if it might...

Hello,
I am hoping to set up a 1000w laser for a pipe cutoff operation. The pipe would be fed to a hard stop, then rotated for the cut. I will assemble a feed-through spindle, so the only questions...

OK, I found the answers so thought I'd post for others to learn. Thanks to Daniel Rogge at Tormach and Bob Yellin at Zbot for the help and explanations.

The manual talks about putting subroutines in a separate file and there is a folder named Subroutines in the directory. Questions: since subs have to be defined ahead of the program, how do they...

I've looked at the Chinese stuff on ebay, but am worried about the runout. One of the motors showed standard collets, but the runout was .02mm compared with .005mm on others. Engraving in steel all...

Ekstrom Carlson has a nice motor, but it's over $2K.

They don't have anything but metric. Anyone know of a high quality spindle motor made in the USA that would have English size collets?

I have a few hundred 3/16" carbide engravers and my Tormach is used full time just for engraving. I mounted the Kress for higher spindle speeds, but they don't make a 3/16" collet. An ebay store...

Signtorch, I appreciate the info. There was a Lightning plasma on ebay, and I found terrible reviews on that one. Dad really needs one that operates on Gcode, so I'll keep on looking. Does the...

My Dad is 91 yrs old, still running his business. He sells Ag equip. parts- disc blades, bolts, cutting parts, etc. He started making hydraulic hose about 10 years ago and has no desire to slow...

I got a reply from a machine company rep who said they don't normally recommend Gcode or programming, but he made a one-time exception and said to try this. It may take me a few days to work it into...

I need to use Gcode to activate a tool height setting.

Can anyone show me a sample code that will position the tool above the toolsetter, initiate the downward move, and reset the tool height...

In December I bought a Tormach PNC 1100 (tormach.com) The top spindle speed is only 5140 rpm, but I'm downfeeding at 3.5 IPM and engraving at 10-12 IPM in 1018 steel, cutting about .007" deep. ...

The spindle speed needs to be around 6000 rpm, with variable Z feedrates. I normally use a Z clearance of .1" and .025" feedplane with an entry feedrate of 10. IPM and rapid retracts.
Thanks

Hello,
My Haas VF2 spends one third of it's time engraving. It is a waste of the machine's time, but after attempting to use a mini mill, I'm still looking for an alternative to increase my...

Thanks Al,
My bend radius is 2" and Belden specs this one at 3.5". I also need hi-flex which is normally rated at about 1 million bend cycles. I sure wish that Cinncinnati had designed with a...

Hello,
Awhile back, my x axis feedback cable malfunctioned. I spliced in some non-hi-flex cable from a local electronics supply and just hung it over the back of the enclosure and down to the x...

Update--- I found the cable on the input board and checked ohms -- no continuity where the table was parked, but got continuity after moving the table, so looks like the cable is the problem. I may...

Hello,
My normally open (first) overtravel signal is not getting through, so it hits the hard stop switch and flags out. I have pulled the switch and it ohms out properly, so might be the cable. I...

Just another note from having the 'tool unclamp' problem... I finally dismantled the tool changer and found that the draw shaft had unscrewed itself from the air cylinder end so that the clamp would...

Hello,
Just saw your posts. I build a channel letter brake specific for the 5" return channel letters. It is at: www.returnrocket.com
