General Mach Discussion / Re: Trouble getting Mach to run anything.

Hi, Lee

I just loaded both your files,Thay seem to run fine for me, Using Mach3R2.00.066 hear.

I think it may be that there are no Preamble in your code to switch you back into IJ, INC Mode G91.1 (IJ, INC) from IJ, ABS G90.1 (IJ, ABS).

Add G91.1 after the G90 line, Not on the G90 line though, Or enter G91.1 on MDI Input line.

Hope this is It, Chip

Thanks, Chip

Hi, Brent

I had the same problem with your file.

Loaded it in Turbo-Cad Exploded it and it loads fine in LC now.

Try this one below.

Hope this Helps, Chip

Hi, Art, Brian

Using Mach3R2.0.065 hear, Looks like you've been working on Turn and LC in general, Lot's of Fixes noted hear.

Assuming that lots of this code will be used on new LC, hear are a few item's I've found.

Using  AOuterProfile.dxf  posted above,

LC is using the Step Distance Units as Bar Stock size in some fashion, Bigger step distance bigger bar dia.

Also cut order in G-code is mixed up, LC preview looks correct.

Fixes noted,

Able to delete Layers in Project Tab and not lockup LC when re-posting G-code.

Mach3 now treats the X0 y0 last line return to origin with out editing G-code.

Just some Info, Chip

General Mach Discussion / Re: Challenge question regarding Homing & Limit Switches

« on: April 20, 2007, 05:05:42 PM »

Hi, Mike

The hard stop sounds simple, 4 NC switch's wired in Parallel, Mach drives all 4 steppers home at a slow rate, When last switch opens Mach

will move them off the same amount of steps, Till the first switch closes.

Sounds OK, Chip

General Mach Discussion / Re: hickup at 12 and 6 oclock

Hi, Graham

I loaded your Settings and Code, steps 1280, vel. 1800, acc. 150, To achieve vel of 1800, You need kernel speed of 45K, Re-boot Reguired after changing.

I dont see any slowdown at 6 pos, But the 12 pos has a pause, It's Caused by the Gcode line change.

Mach ramps down using your Acc. setting even in CV mode.   

There is a relationship between Steps, Vel, and Acc. settings, Hear is an example.

I have a Sherline mill with a 4th Axis, 10 micro steep controls.
X, Y, Z settings, S 7500, V 40, A 18
4th Axis, S 400.2, V 2500, A 500

Give this a try, set your Kernel speed to 45K re-boot if needed, S 1280, V 1800, A 350 - 450.

The way I setup from scratch is set slow Vel. Acc., Calibrate the Steps required to move 1 unit, Inch/MM.
Set the velocity up to a speed that you trip/lose steps or it's just too scary!!, Then back it off some.
Set the Acceleration up to a speed you trip/lose steps then back it off some.

This will give you a Max speed for your G00 Moves, F- Setting for G01, G02 & G03.

Note: You need to do some X, Y, Blended moves to determin whether you lose steps with multi axis moves.
You may need to reduce the Max Vel. and Acc. some, If your start / return position is off.

G00 X0 Y0
G00 X10 Y10 ( adjust to distance to get max blended Vel. to display)
G00 X0 Y0
M30

Additionally you may need to reduce your Acc., If it's to fast for the material your cutting.

It's all a balancing act any way.

Hope this Helps, Chip

General Mach Discussion / Re: Z Axis Drift Problem...Losing Counts on a Servo System?

« on: April 17, 2007, 02:05:15 AM »

Hi, Mariss

Will increasing the step & direction pulse length in Mach3 help dampen this issue some, not sure of the actual max values, there seem to be 2 places this can be set, Motor Tuning and Ports & Pins, maybe up to or more than 15 us.

Just reading through some posts tonight, Have used your drives, stepper & servo, None with micro-step option though.

Thanks, Chip

Hi, DirtyBird

Give this XML a try, Turned on Jog On/Off, (Hood), Changed Dir/step  LowActive state to "Checked".

Hope this gets It, Chip

Hi, split63

Have you tried cutting this out, I think your corner of "contention" will be square.

Go back to LC load your file generate an outside .25 offset.

Right click on your Layer 2, Delete it, Now generate a inside layer on the remaning object.

Looks like a square corner to me.

The tool # is used by Mach to select your tool with the .25 rad. cutter, For proper offset.

Wow what a Bata Program, Sorry for the "Rev. Engineering Hear".

Thanks Art, Brian and All, Chip
