General Mach Discussion / Re: How do you apply a different offset from home on a slaved axis?

« on: May 17, 2019, 08:26:09 AM »

both axis are rotating the material but they need separate homing sensors

At this point we have both axes slaved together, and each are homing to there individual sensors.
Now I would like to make their 0 location at different values away from their individual homing sensors.
Is this possible? 

I think it can be done, but how automated it can be i don't know, without playing around.
Not going to spend time playing around.

A modified screen page with proper DRO's, buttons, and VB can be used to manipulate
conditions. Typical setup is to reference the machine then define a Work Offset to the part.
Using the generic sceen you are restricted as that is for conventional / typical setups.
When you reference a machine you define to the controller where the axes are and the play on words is
that  homing / referencing is the same and that is not exactly true.

Conventionaly Y axis is linear C axis is rotational. Uncoventualy you can do whatever ....which can create problems
,but, the controller is stupid and only knows what you tell it!

Attach your xml file so your cofiguration can be reviewed.

FWIW,
I also do similar to Hood's reply #112, but, no switches used here, so home and any work offsets are
set manualy.
By similar I am meaning, all tools have the same base location from which they move to touch off.
Tool offsets are probed instead of touching off or machining, taking a measurements and inputing info.
Probing makes populating the tool table quick, accurate, repeatable, and somewhat automated. BUT,
a tool setup page to accomplish the above was done.
Once a tool table is populated all tools relate to the master tool ( could be an actual master tool or
a common base location) and all tools relate to each other. Thus you can use any tool to touch off
to the work or setup to replace a tool.

Have fun.......,

Note that the primary axes are:
X     Y      Z     the related rotary to the primary axes are
A      B     C     
Rotary axes allow for indexing and rotate about the associated primary axes.
Rotary axes steps per units are in terms of degrees.

Offset needs definition since there are diffferent kinds of offsets.
Home can be anywhere, but, home is defined by the user to the controlling software which is  Mach3.
Home location can be defined as machine coordinates 0,0,0 thus once defined to Mach3 it is
said that the machine is referenced.

That said,
Do you have the C (slaved axis) moving correctly for a commanded distance of  Y yet?
Post your xml file.

General Mach Discussion / Re: Noise and wrong movement of stepper motor on mach3

« on: May 12, 2019, 08:20:12 AM »

i am facing noise issue from stepper motor

Newbie,
Drives and motor tuning need to be set properly.  The noise will go away.
Do some reading on the basics.

It appears that the CNC mill doesn't have any home switches or homing facility.
 What would happen if the carriage hit the end of travel? Damage? or overload?

Simplistic answer is it all depends on the conditions at time of impact. The resultant affects of the
impact can vary from nothing to major. 

Safety considerations should be personal safety primary and damage to property secondary!

Personaly don't have switches on any of my machines except a hand held manual kill switch to stop axis movement instantly.
I don't recomend what I do to anyone!

General Mach Discussion / Re: Lazycam "Pro Demo.No GCode" but have Mach3 license?

Happy for your progress. The manual for LT took a lot of work and time to do and glad you appreciate it.

There are higher end programs for a CNC lathe. Keep in mind the following relative to CNC programs.
Use the best of the best for intended work. Matters not if it is LT, a Wizard, Fusion 360 lathe, Dolphin, etc.
That includes doing the work on a manual lathe. A soon as the work involves multiple parts or complex shapes
CNC really comes into play.

Have fun,

Just wanted to turn a profile on the lathe

I would suggest you use LazyTurn, which is free, has a manual for it ( Member's Doc's), and was created as a replacement for the LazyCam lathe module.
It's far easier than LC and LC is buggy ( tool definitions were never finished along with other things ) for the lathe.  LT is quick and dirty for profiling just make sure you RTFM and don't hack it!

The wizards are usefull but be aware that some may only work in one mode ie; radius or diameter.

BTW, LC or LT are DXF importers so need to create a profile of the part in CAD.

General Mach Discussion / Re: Lathe arcs G2 G3

« on: May 09, 2019, 05:59:28 AM »

I wrote something called Mach3 Turn - Arc Motion a long time ago and should be in Members Doc's.
It covers a lot about arc coding for the lathe and also contains examples of coding.
See page 3 and 4, but, suggest you review all the pages.

Note that I did modify the CPS file to remove unwanted code that it generated and frankly you really need to know how to do and  what to look for.
There is an "hour long video" on how to modify a post processor, but guessing only that video was on You Tube....so could be wrong.

Sorry, but, it's been over a year since I used Fusion.
