Cool. Thanks Gar.
I'll post and let you know how it turned out.

The part size comes out just fine. It's the approach that's all over the place.
I'll go back in AutoCad and see what template is entered.

I'll try again.

My machine is a little sig X2. The envelope is about 3 by 8 inches, Y and X. When I transfer a drawing to lazyCam and then into G code I get a Y axis with 19 or 20 inches of travel...

Is there a way to set the drawing envelope size in lazyCam to the same size as my milling envelope?
When it generates g code for Mach3 it has x and y travel far in excess of what my machine is...

Thanks Tom and Jeff.

My background is that I design and build high speed machines that apply thread locker ahesives to fasteners- I put locktite on nuts and bolts. The electronics on these...

Yes. I suppose I could do that, but then I wouldn't learn anything either. Building stuff like this is as much about self reliance as anything else.

Or just a printed circuit board? Some of those ready made THCs are pretty spendy.
Did I mention I'm on a budget.

As a rule of thumb on grey PVC. Run it at alum. speeds if not higher and use razer sharp tooling. Otherwise you just run the risk of melting it. If you have coolant all the better.

I have the same basic setup as you are considering. I'm using gecko 201s and the same keling motors on the x and y. As far as motor power is concerned, I'd rather have it and not need it than the...

Antelope. And I don't think there are any in Alsaka.

Having lived in and around Chicago my whole life, I'm not ready for that particular pack of liars and thieves in the White House. Barak Obamas...

For just ten pieces you could just buy a straight broach , make a bushing with the correct spacing and do them one off, by hand. providing you have access to a mill, a lathe and an arbor press. ...

Custom cutting tools are usually for high volume production of a specific part. it was much more prevelent for scew machine tooling. Not many screw machine houses anymore.

Do the motors lock up?
If so, see that you have the motors wired the right way.
it's almost always something simple.

What stepper said and to add cutters should be razor sharp. People run into problems when the cutting is dull and the material is melted rather than cut.

How long should the cables from the motors to the drives be?

Try switching from low active to normal.

An early Dell optiplex. Yeah in the startup menu I can change the parallel port from PS2 to AT to EPP.

DJH. How did you get there? I couldn't find in the startup menu(pressing F2)
Thanx.

It's rock solid at 25379. This is getting very frustrating.

FWIW
A model engine builder in England has done such a thing with computer operated solonoids valves on a two cylinder motor. No valvetrain. No gears. Supposed to be very fast and smooth.

I'm having that exact problem with my setup as well. The motors chatter and vibrate but don't want to go in any direction. When I input G code the motor moves very slowly, if at all.
Artsoft...

Aaarghhhh!

No limit switches yet. I just wanted to test the motors. I'm going to retrace all my wiring and then dump a bunch of stuff off the hard drive. you know, clean up the operating system a little.

A little more info mght be in order here. I'm running it on a 1.8 gig Dell optiplex with 512k ram. I know Mach 2 is supposed to run at 25000mgz but the clock in Mach2 says I'm running at abot 23000....

Sorry if this is redundant. I'm trying to jog two steppers in x and y on my minimill and niether will budge. The motors lock up, but won't jog. I'm also getting a persistant flashing 'overide limits'...

34s seem a little large for such a small mill. I thought I'd look for some 350 + or - 23s for my project.If they make them that large .

Thanks LR. I think I'll do what you did for the X axis and then just make an adaptor plare to take the excess nut further over to the right. With a little judisous(?) milling, ( I have access to...

I have an X2 and I'd like to convert it to ball screws and steppers. Has anyone milled relief in the base to accomodate the ball nut? Both in front and behind. Also. Has anyone come up with away to...

The gearshift yokes are getting hung up in thier slots. Move the gear shift levers around and the gear column should fall back in and the yoke will be free. You can then lift the gear cover off.

Sounds good. Anything that will flood the tool with coolant. If you are going to tap a hole in copper shoot for 75% threads.
