Hey all,

Not sure if this is backlash related or settings but here it is.

As described in a few manuals to test for backlash I run the following code to see if my axis comes back to the correct position.  And it does!!  I can run the 50 times and it works great (the code shows 5).

My question is this:
I noticed that while the axis returns to the correct position it does not come back to zero during the move.  I have posted two videos to show this. One regular speed and one slomo.

Please fire away with comments...

CS-Lab / Re: Camino/ip-m spindle speed

negative.  no luck. Maybe its the screen I am using?

I have emailed CS-Labs and the distributor again.  Maybe they will reply.

Hood,

Here you go. Any information you find would be very helpful. Not sure what state I left it in since I have been bouncing around trying to see what does what.

Thanks,

CS-Lab / Camino/ip-m spindle speed

« on: January 19, 2016, 01:00:54 AM »

I am trying to get the spindle speed to show up on the screen and use the spindle speed control within Mach3.  It worked before I upgraded.

I upgraded my siegx2 from lpt ports to the csmio/ip-m.  I have the standard spindle drive, using ampi stepper drives. All the I/O works fine,  steppers move without a problem, probe input works, the index shows on the diagnostic screen, the analog output to the sieg spindle drive works and is linear from 1500 to 4100. So the spindle works fine but the speed does not show and it does not seem to be closed loop. 

I have read the manual, followed the instructions from csmio.

Any feedback or questions would be helpful.  I have emailed the distributor and the manufacturer on the some other topics but have not received a response so I thought I would try this...

Thanks,

Phill

Figured it out.  under M8 is states output # and I was thinking pin #

General Mach Discussion / M8 Flood output not working

« on: October 06, 2013, 11:20:16 PM »

hey all,

I am setting up a flood output and M8 does not turn on the output.  I am using output 5 port 1. 

The output works when I use the "output tab" under "Ports and Pins".  I test this by setting Output#1 to enable and use on port 1 pin 5.  Then I select active high then active low and the output toggles. I then turn this output off and go to the "Spindle setup" and enable "flood mist control" and set my output to pin 5. 

I have tested the output two different ways.  1) I go to the diagnostic page and toggle flood and nothing happens. 2) run code with a M8 and it does not turn on.  Also,  When I restart the PC the output it on which is odd but I can live with that. 

I think I do not have to setup an output since the manual states it is automatic. Also,  all other outputs run fine, XYZ and spindle.

What am I missing?

Thanks,

Phill D.

Hood, 

The backlash started working after I rebooted the PC. and the x axis is half the distance since I am in diameter mode.

200 RPM is the fastest I can go with the acme screw on the z axis. I using AL 3/8" and Steel rod (from ace hardware). 

The cutters are from harbor freight that I grind to a point. No clue if they are C2 or C5??

I will keep experimenting...

One thing I have found is that machining is like art.  There is never just one option, one answer, and there is never enough information to understand why.. Maybe I should take a class.

General Mach Discussion / Trying to understand thread wizard

« on: September 20, 2012, 11:33:07 AM »

hey all,

I have a 7x10 harbor freight lathe that I have cnc'd with mach3.  I have been trying to make a spring loaded engraving tool for my mill and I have a couple of questions:

1) When I enable back lash the axis movement starts to act strange.  I hit the up arrow to move my x axis in and the axis move the desired length then it adds the backlash movement, plus it moves too far.  My mill does the opposite.  it moves the backlash amount (at desired speed) then moves the entered distance.  Should I be using backlash on the lathe wizard? Does is act the same as Mach Mill? My back lash is about .005"

2) Can I turn "good" threads at 200 rpms?  I am using the acme threads that came with the lathe and simply added steppers to the ends for the x-z movement.   I have single slot encoder and the speed is accurate. It seems to do AL ok but mild steel seems to be an issue.  Would I better off using brass? Should I add ball screws so I can turn faster?

3) And when I do turn, I find that the measurement guides for turning threads do not work for me. I always need to adjust the major and minor thread size to get a bolt to go one smoothly.  I would think this has something to do with backlash but see item 1.  Or I would think this has something to do accuracy of the steps/distance.  It would be nice if I could set the steps/distance like mach mill. but I have good distance if you do not could backlash.  For example, I can zero the x by touching the diameter and set it to .3" then I can turn it down to .2" with the wizards and I get a good result.

4) Are there any videos that explain more about mach3 thread and the wizards? I see a million people show them making threads but nothing about how they actually got there, what measurements they use, why they are going a certain rpm, what tool is better.  Or is this the nature of the beast?  My expectation is to place a piece of rod in, set the parameters, cycle, walk away and come back with a perfect thread...


Sorry if the questions seem stupid... I am hack at machining and the only parts I have made are parts for the machine over a 3 year period. this is my first real project with the lathe.  The Mill works great!!  I use cambam, turbocad and mach3 and have made many parts for years.
