I was asking the question of Ian. I would love to come to the BBQ but it's a bit far from Sydney to Melbourne sorry.

That's exactly what I was saying. If you have three sections in the sliders rather than two as shown you will get twice the travel.

The attaching of the sliders is as designed The sliding bit...

Software like Mach2/3 has a constant in the motor tuning for each axis that is calcullated from no. of steps per rev of motor, the pitch of the thread and the micro stepping factor of the driver so...

I think that less space could be takenup it the two slides are offset vertically so that they can truely overlap. I also think with this design that if the closed length of the slide should be the...

I realise that the usual conversion is to multibly by 25.4 and have always used this.

However I was making some printed circut boards and found that on large multipin chips that the legs slowly...

No I think that the gist of this question is why use HPGL.

Some graphics programs can print HPGL and this can be imported into some Gcode creating progtrams. It may not be the best way but if you...

HPGL is/was a commonly used format vector (I'm sure Straight Line Vectors) for moving pens around in pen plotters. So it is fairly good at describing 2D objects. The commands in 2-axis are not unlike...

Hi Andy I am still playing with CamBam. I had a little trouble downloading .net2 but it may have happened last night.

Joe yuur idea is good but the surface of the torsion box in my Jgro has sag in it and is all glued and nailed tohether so I hope to fix all this by skimming the surface. I have stabilised it and even...

I have been thinking along the lines of surfacing the table but am not happy with with the surface that will be left.

My solution is to surface a piece of MDF so it is parallel to the router (...

Why not try progecad or A9cad

http://www.progecad.com

www.a9tech.com

Both are free and Progecad is similar to Autocad

Just a thought, What about spring loading the cutter?

Don't Take any notice of Phillby's Gcode he just doesn't know. I will say though he's learning.

I should know as you can see I'm he.

Cheers

Some one was building a gantry out of steel to mount over a wood lathe in the last six months or so but I haven't seen anything on it for a while.

I am also interested in this Idea.

I don't mind but it is a short week. I am tied up Thursday's & Friday's. So as Tuesday is Anzac Day Monday or Wednesday would be suitable.

The current limiter is needed in each individual motor supply. IE the actual leads to the motor.

I Used Pminmo 3977 circuits the current max is 2.5A on these.

We may all be using Linux soon when Vista tries to take over the world, even specifing what hardware we use.

I had a similar problem importing a DXf file into 10Bulls CamBam. I fixed it by making a polyline and joining all the segments. My drawing had fillets on the corners, which had the rest of the circle...
