Hi, Willem

I cleaned up your DXF a bit.

Hi, Willem

It was Dave that posted the new pic. of the tail feathers, Although I got the same results using .01 Load tol.

Part of the problem with the dxf is there are a few unconnected lines in the wings, See below.

I'll look it over a bit more, Was tied-up earlier today.

Thanks, Chip

Hi, Willem

Post your DXF file, Do you have the LazyCam Lic. ?

Now I can see what your trying to do, The lines in the middle should not connect to the outline shape.

If thy don't, In Setup, Loading Options, Connection Line Tol., Set it to .001 or .0001 and re-load your dxf.

Maybe as Dave stated use "Chain-Ent Sel" to select the outer entity's you want, Then use Offset, Then delete them.

Thanks, Chip

Hi, Curtis

Open up your file with Notepad, Select Save As, Now Select Save as type to "All Files", Then on the File Name Add the  ".PST" and Save.

You can change allot of item's in your .pst, Read the example several times, Add notes in the post ' ----------Rapid 1 G Mode, You'll see them in your posted Code and will help make sense after awhile.

Hope this Helps, Chip

General Mach Discussion / Re: Calibrating each axis?

Hi, Archerks

Is this when moving in one direction or both,

If It's in one direction, It's a backlash issue, Lost motion in your drive train screw/nut.

If your step per is less than 1000 steps " .0001 per step", Then Mach gets as close as it can in steps and holds the partial step/move value to be applied on to the next move and so on till it gets to your 1 inch.

What are the Step's Per values in Motor Tuning for your axises.

More info needed, Chip

Hi, Dave & Jonny

I've had these Cir. from nowhere at times to deal with also, Reorienting, editing them out in Mach after posting.

As far as Tricks and things to try, Someone (Sorry I don't remember who) suggested that after you load your dxf and clean & optimize it, Post it to Mach then, Use the "Mach3Load" Button/feature in LazyCam to retrieve it back from Mach and use it to do all your modifying and then re-post.

I've had some success with doing this with problem drawings, Give it a try.

Thanks, Chip

General Mach Discussion / Re: Moving off Limit switch
« on: May 06, 2008, 06:05:35 PM »
Hi, Daniel

Limit switches are Limit's, Last Line of Defense, An "E-Stop Situation".

It Requires "Further Action" By Selecting "Limit Override" and Joging off the switch in the proper Direction By the "Operator".

Many Machines work this way, Requiring "Further Action".

As Hood Stater,

Set up your Soft Limits, It is what your describing/looking for.

After you home Mach, It moves Just off the SW and it revert's/changes to a limit SW.
DRO's zero ("Current Position" & "Machine Coord" to 0,0,0).

Soft-Limits work, At/Just inside your Limits, In "Machine Coord" and will slow down your feed-rate and stop just before your Limit switches would Trip.

You can Jog and Zero your to a "New" Current Position and the Soft limits remain just inside your Machine Limit Switch's,

See Pictures Below:

Dashed Lines are Soft-Limit's 0,0 X100" by Y50" Table, Part is at 0,0 Current Position.

If you hit a soft-limit you can Jog off it but not Jog further into the switch.

If you don't trust Soft-Limit's the "Limit" sw's are there to Save you.

Mach provides a way to setup Limits & home swithces using the Same Switch's with 1 Input Pin. You wire all the switches "NC" Normally Closed and in series with one another.

Mach now's which axis is moving during Homeing and only looks for a switch to open,
As the Operator you should be able to See what's going ON.

Why trust any cnc Machine , Hand Crank it!!

Think About It, Chip

Hi, Daniel

Selecting Limit Override is just to move off the Limit Switch then you turn it back Off.

Thanks , Chip

Hi, Tom

Hold down your Shift Key and press an arrow key, Is it faster ?

Mach installs with a Feedrate set to 6 in a minute, Look on the Program Run screen and click on the Feedrate DRO type in 100 then enter, Now Hit the TAB key and click on the Slow Jog Rate DRO type in 100 then enter.

This will set you up for 100 in min with 100% of that for jogging, Not sure whether youll be able to go that fast, Just a start.

Look at some of the videos hear,  http://www.machsupport.com/videos/

Ask your questions on the General Mach Discussion section, Probably get faster answers there.

Hope this Helps, Chip

Hi, CNC4fun
