General Mach Discussion / Re: Drifting X-axis, making step ladders one side whereas other side is smooth- SOS

Measure the voltage, say, from the control panel box to an earth ground / water pipe. Only a few milli amps can be a hazard.
You should not be getting any shock from the panel. So safety first. 

Trace out the wiring, draw a schematic, post it and someone will take a look to see what's  wrong.
Don't use it until you have made it safe.

LazyCam (Beta) / Re: Quick questions about LazyCam

« on: July 09, 2010, 03:26:16 PM »

LC imports a DXF file which was created by a vector based CAD program. I know nothing about Corel Draw anymore.
CAD programs allow for assigning layers or levels based on whatever part of the profile you want. The layers should
be created before the DXF is created.

Paint programs are not CAD programs.
You can move different entities / create layers in LC, but.......LC IS AN IMPORTER AND SHOULD NOT BE USED AS A CAD PROGRAM......
becuase it is just not worth the effort in my opinion. You should know what & how you are going to machine something before hand.

LazyCam (Beta) / Re: Quick questions about LazyCam

« on: July 09, 2010, 10:32:23 AM »

jasko,
I quess your looking for the magic wand to convert a raster to vector and generate the gcode for use in Mach.
LC manual is written based on using a vector generated drawing. Yes there is a module, but i didn't even waste my time with it
because i don't use that magic wand or any others .....i can draw it faster and have control over what i need to do.

Due to the availability of other low cost CAM packages, LazyCam is in semi-permanent Beta and no longer being actively
developed.  LazyCam is not intended for use in a production environment.

So sorry i can't be of any help.

General Mach Discussion / Re: cutting out of line with the toolpath

« on: July 09, 2010, 10:17:46 AM »

Hmm,
I would suggest you recenter / adjust the piece to the quill before doing the outer circular path. At least it would be symetrical.
If you have scales on the machine you should be able to return to some point and thus you can compare to what Mach's  dro's are showing
.......and certainly it should not be 1/4" off........
Check you steps per unit, code , and machine mechanics that all is well.

Scott,
There was an article in one of the magazines ( Home Shop Machinist ? ) some time ago about the single cutter you mention in your first post or that video. It talked about how to make and use it for different gear sets. Was interesting, i'll see if i can find it in my vaults of how to's....

JASKO,
You need to provide a file which contains the code to machine the part ( ie; a file which has Gcode).
So if Corel can post process the information into a file used for machining you would be good to go!

You can use Mach without LC installed.

Only new floss.  I wish i had some pictures to show you but all those guys have gone to muzzle loader heaven........
It's really tuff to find that piece of curly maple which would run right to the end of the barrell. When finished you would see light and dark areas from the wood grain and in absense of the grain the floss trick was neat...need to experiment to get the right affect, been years since i did that on a set of dualing pistols.

They have a PEG ( it's  different than the engine collant stuff ) and you let the wood sock in the stuff so it won't crack when drying.
Haven't used it in years ( i think Constantines out of New York sold it ( they have been out of buisness for a long time ) )

All this useless info stored in the cloud above my head....all it takes is the right posting for it to be remembered.

No i don't do wood working, concrete , roofs or siding anymore .......  just a comment before you even ask
