Hi, Steve

The version is the latest, You need to change the direction and look at the dir arrows, Use the S key to simulate the cut, S key to turn sim off, Then post the code.

Hear are 3 examples and a Lset  to look at.

Hi, Fred

I did find your G code file, It was a Preamble setting and posted your G code with a G91.1 in it in my post above.

Glad you got it sorted out, Chip

Hi, Fred

Post the dxf file we'll look at it, May just be a setting in Mach3 like a g90.1 or g91.1 IJ's in abs inc mode set incorrect or XY XZ plane setting.

You  need preamble setting's in the top of your G code to configure Mach to the "Proper State" to run/display the Code properly.

Put a G91.1 in the top of your G code, Look's good hear, Try the att. G code file.


Hi, Paul

The drive boxes your looking are +- 10 volt type and not "step & direction" type that Mach prefers.

There is a discussion hear http://www.machsupport.com/forum/index.php/topic,12233.0.html that you might want to look at.

If you had a system already using these type of drives then the cards there talking about might be OK, But if your starting from scratch it's probably not the way to go.

Hi, Steve

Non climb and climb mill pictures below, You'll see the direction arrows of cut easier with the cir leadin's on.

Direction of cut arrow's are a little hard to see sometimes.

Rich, Guess I need to read your manual a little closer HU   ;D

Hope this helps, Chip

Hi, Steve

LazyCam has a learning curve as do all programs, Have you downloaded the Manual RICH has done hear, http://www.machsupport.com/forum/index.php/topic,12078.0.html

Its a Very Nice manual and covers allot of quark's you might find, Way to Go RICH !!!!!.


Hi, Dave

Sounds like you have a 25 pin serial cable, What you need is a straight through printer "extender" cable, 1-1, 2-2, 3-3 ...25-25, Some cables omit some of the 18 - 25  Gnd. wires, But this shouldn't be a Issue, Gecko is probably smart enough to have them all tied together in there box.

Thy come in two versions, 25 pin M / F and F / F connector's, The F / F you'll need a gender changer M / M adapter.

Hi, Dzackman

If your steps per values are 509 per inch and you have an error of .002 per unit, Then on a 20 unit move of your axises error could be .040 just with that may be why the large outside profile is shifted sow much and the inner profile cuts look closer to what thy should.

On your stepper controls see if theirs a micro step by 10, That would give you a steps per value of 5090 or so giving you the ability to calibrate your axises more accurately.

If you used the center of the part as the origin 0,0 point then the errors would be distributed from side to side up and down, See pic's.

Just some more thoughts, Chip

Hi, Dave

On the Diagnostics page do you have a Pulse Frequency showing.

Try this xml file below, I think I got all your settings correct and enabled Sherline 1/2 step mode also.

Hi, Steve

CW and CCW can get confused in the Cam packages sometimes, What are you using to generate your G code files ?
