I'm in Louisiana and this item is for local pickup only. As far as cutting brass is concerned I wouldn't recommend it with this machine. This is a
CNC router designed primarily for cutting wood and...

Probotix Fireball V.90 Turnkey CNC Router

Fireball V.90 turnkey system including stand, lighted dust enclosure, pendant, and computer system. The spindle is a Rigid 2401 trim router and comes...

I have been trying to use the gear module with no success. The software seems to be locked
to a diametral pitch of "8" and will not allow me to change it. I can change the pressure angle
and number...

I'm having trouble with using the Peck Drill operation. When I post process I get this error: "post processor error: "G83" at line 1 in Rule NPECK Syntax error".
The post processor is:...

Hi MD,
I see that you used a few of my designs on your build, cool. I've been busy with other stuff
so haven't been frequenting the CNCzone but I just wanted to compliment you on your work
on the...

Thats the size of the table without the end pieces as your picture shows.

The SX2 table is 18.110"(460mm) x 4.725"(120mm).

I noticed that I left an entire page out of the plan set so I corrected that error and another small mistake on the X axis exploded view sheet. The page I left out by accident was the saddle...

I tested the replacement ball screw assemblies that I received a few weeks ago and found them to be much better than the originals. The ball nuts fit to the shafts were noticeably tighter unlike the...

Did you check to see if the spindle was tighter than usual when the motor shut off? Maybe the bearings have to much preload and are overheating causing them to bind and overloading the motor...

Did you check the ballscrew for concentricity? If the shaft wobbles you will have more binding in the front than the back no matter what you do because the shaft is able to deflect more on the...

I haven't put them back on the machine yet but they feel tighter than the originals so they will probably be ok but we'll see. If your getting more backlash one way than the other I would think you...

I finally completed the plan set and have reviewed them one last time for mistakes so I'm going to go ahead and post them now. I think I spent more time doing the drawings than actually making all...

I haven't posted to the thread in a while so here's an update of my current progress. I've been working on finishing the plan set a couple of hours every night for the last week and have most of it...

Sounds like the collet is being pulled to far into the spindle causing it to become bent. A simple solution would be to make a spacer that slips into the spindle just long enough to limit how far the...

I doubt that the switch is the problem. The extra heat should have little affect on the switch. The best thing to do to be certain is to eliminate the switch altogether and see if that alleviates the...

The switch on the LMS SX2 as well as many other newer machines is a safety latching type switch which run a little on the hot side normally. There is a solenoid in the switch which keeps it in the on...

The units in the catalog are newtons not pounds, 2910N = 654lbs. The max load needed to fully compress the washers is about 858lbs or 3821N.

I'm planning on getting the CNC plans finished by Christmas.

I finished up the power drawbar plans last night and reviewed them couple of times to make sure I didn't miss any mistakes. If anyone sees something I may have overlooked, let me know so I can fix...

The swappable head idea sounds like a good solution. I've been pondering doing a larger machine sometime in the future after I complete the SX2. I'm thinking if the world manages to hold together a...

I'm aware of the size difference, I have a X3, but what I was wondering about is if the X2 spindle would be adequate considering it's smaller size and lighter weight. Since speed is more the issue...

Hey Hoss,

I was wondering if you ever considered replacing the stock spindle of the g0704 with your old X2 spindle. If you use the X2 spindle you could save a good bit on weight and be rid of the...

I don't recall that being discussed on this thread, maybe it was another.

He could make it work on a big machine like that by scaling it up a bit. He would need at 3.75" pistons to generate about 2800 lbs. of force.

~Don~

Thanks for all the compliments guys, but basically I just incorporated the best ideas I came across into a simple design that I think will be easy for anyone to build. I was shooting for something...

The pistons are seperate held together by a 1/4-20 screw. The top piston is the only piston that is double acting for the purpose of retracting the shaft, no need for 1000 lbs. of force to retract...

Ok, I finally got around to doing the power drawbar as you can see below. It consists of 3 2.25" pistons with .175" stroke and develops over a 1000 lbs. of force @90 psi. It's contructed of all...

I shortened the nose of the collet by about .050" so that the tool holder would clear it. Because the collet is hardened I had to use my tool post grinder to shorten it. I would suggest you do the...

In the last couple weeks I've started doing some more work on the mill and have got it ready to do some test cutting. I remade a couple of parts that I wasn't happy with as well as designed a column...
