how was te road runner created ?
« on: May 25, 2013, 08:54:49 PM »
First
Can some one tell me how the road runner was created.
I finally cut the road runner.
==========================
So my machine is working.
As for me I'm still lost.
But I did cut the road runner.
===================================
For me to change the cut size of the road runner I have to change
the motor tuning section.
Is this the way it  is done.
I went from 320 then up to 2000 then up to 5000.
three different cuts.
If I knew how the road runner was created I would be able to get a better handle on this stuff
Thank you

I'm not 100% certain but quite sure the Roadrunner was created with a cam package.  Cam software will use art work and other drawings to generate g code.  Maybe not as simple as it sounds but that is what it does.  Have a look at Vectric CNC.  I'm thinking they have some videos.

Good for you!  It is pretty rewarding when you get to see your labors paying off.

No, you should never change motor tuning to adjust the tool path.  You can easily scale the code by entering a value in your scaling dros beside the the dros on the run screen.  To make it half size enter 0.5 (remember t put in the zero)  twice the size enter 2.0.

OK
I knew I was missing something because it seemed crazy to redo the motor tuning
once you got it all aXIS MOTORS running smooth.'
Thank you

Robert.
 What units are you set up in and if you command a move of 10 units does it move that distance?

Hi
I'm still new to this and took a break since I last spoke with you,
to plant my VEG garden so I can eat and store food for the winter.
I just got back at it a few days ago and made some head way.
========================================
I'm set up in inches if that is what you mean by units.
Trying to get the hang of the language.
Units ? Where is this and how do I check it out.
I'm assuming I put the command in the MIDI SECTION
Like GO ?????
correct me if I'm wrong please
I'm going back to the shop now to redo my Motor tuning and leave it
where the all axis motors run smooth.

Thank you

Your initial setup you need to choose which native units you will use, that is metric or imperial and that is the only time you change that setting. You get that from config menu then Set native units.
 You can then go into motor tuning and set your steps per unit and yes unit is either mm or inch depending on the native unit setting but can also be degrees or rotations if using a rotary axis.

Anyway you calculate what the steps per unit should be, steps per inch in your case, that will mean when you command a 1inch move it will move exactly 1 inch. Again as Brett mentioned that setting does not get changed once set.

MDI, yes you can command from there, for example if you zero the X DRO then type  a G0X1 in MDI then press enter the X axis will rapid move 1 inch. If you then type G1X2F100 the X will move a further inch but this time at a feedrate of 100 inch per minute.

OK
I started from scratch a few days ago.
Redid the whole system computer etc.
Set my units to inch.
Got all Axis working and cut the road runner.
So I will give what you suggest a go.
Thank you

Lot to learn.
Will try not to jump around here.
My key board arrows now work as they should I made the change in the hot key section. Great
===============================
when I go in the MIDI
G0X5 = 2" of Travel
G0X12.5 = 5" of Travel
But it is going from right to left. this does not seem right
G0Y12.5 = 5" Travel in the + direction  seems good for now
G0Z5 = 2.5 going up Seems good for now
When I start the roadrunner I put the spindle all the way to thee right of the table
because the travel seems to go from right to left and up the Y Axis
Is this how the road runner is programed or is it because my X axis is starting from the right of my table.
Just a small picture of my machine.
See picture

I think this topic will help.  It explains the right hand rule.  If your machine does not follow standard convention your paths may be upside down, mirrored, or a combination of the 2.

Also, I meant to say there are a couple of topics in the members docs board on steps per and backlash you may find helpful very soon.
