Show"N"Tell ( Your Machines) / I have rotary movement now
« on: September 14, 2017, 10:30:36 PM »
Well I got the rotary axis to move.  I went into USB SS data monitor and noted that when ever I used the MPG to move the 4 th axis it was the A axis that was active.  So I went into mach and switched from using the B axis for the rotary to the A axis and I have movement!    This leaves me with a question.  I was Googling around about A,B and C axis today trying to figure out if it mattered what one I used.  From what I read it looked like A rotary should be parallel to X, B rotary should be parallel to Y and C should run parallel to Z.   Kind of made sense when I read it.  But my setup will have A parallel to Y,  Now I could swap my X and Y around if needed.   Any help wrapping my brain around this would be appreciated. 
Thanks,
Todd

Thanks Tweakie,
I have decided to use B as for my axis of rotation for now.  I can switch it later, that is no problem.  My currant problem is I can not get the rotary axis to move.  Below is what I posted on the PMDX forum but have not received any feedback.  I now think it may be a Mach 3 setting or something I am missing.  The rotary axis has no home switch  so I guess Mach 3 never tries to home it?  On the Mach page the 4th axis has a red box around it while x,y,z are green after homing,  is that why I can not move it?  How do I tell mach where home is for the rotary axis?  I think I am missing something?  Thanks for any help ???

"I have a PMDX-126 run by USB SS and I am trying to get a rotary axis working.  The axis is driven by ClearPath SD servo.  I have  step wire going to pin "16" on J6 and the direction going to pin "17" on J6.  The enable is connected to +5 PC and all commons are connected to ground PC.   This rotary axis uses the B motor in Mach 3 and is parallel to my Y axis.  I believe I have all the settings in Mach correct.  If i try to use MPG to move the rotary axis The numbers on the screen change  but no real movement. The servo drive is in servo lock.  I do not see the LEDs at pin 16 or 17 light or change at all.  I do not believe I am getting step or direction signal from the PMDX-126.  All my other axis work x,y,z and C slaved to X.  Any ideas?  what am I do wrong?"
Thanks,
Todd

Hi,
I am adding a fourth axis.  It will be parallel to the Y axis,  so I will be wrapping the X axis around it.  Should it be the A  or the B  or does it matter?  Right now I use the A axis as a slave on my X axis but I can change that to the B or C if needed.  It looks like the post processor in V Carve uses the A axis for a rotary axis.  Thanks for your help.

General Mach Discussion / Re: Homing the wrong direction

Never mind my mistake.  Somehow the home negative was set to home positive.  How it got switched ?
thanks

General Mach Discussion / Re: Homing the wrong direction

Back working on X homing in the wrong direction.  I noticed that if I switch to machine coordinates my X is -4.123   That means the software thinks I am on the other side of my home/limit switch?  The question I have is even with it set to home X in the negative direction does the software think i am already past the home switch and moves positive looking for the home switch?  The other question is how can I type in or enter a positive value for my X machine coordinates and try homing ? 

Thanks
Todd ???

General Mach Discussion / Homing the wrong direction
« on: March 23, 2017, 08:13:12 PM »
Hello,
I did some MDI cutting on my router and now the X axis is homing the wrong direction.   The limits and homing is still set to home negative but it goes positive when I ref all.  Could have I typed something in the MDI limit that caused this change?  I powered everything off and on and it still goes positive when I home the X axis.  Any ideas
Thanks,
Todd

Hi,
I am going to tag on to Jim's post because my problem is similar and his post helped me get my relay clicking on, but it will not stay on. I have a PMDX-126 run by SS USB board.  My K1 relay does click on but goes off immediately, with the error message limit switch tripped. On the diagnostic tab I see no active inputs.  I think it must be some config error. 
Thanks for any help.

Thanks Tweekie.

I will attach some pictures of items I have made with this router.

Show"N"Tell ( Your Machines) / The CNC router that ate the family room

Here are some picture of the CNC router that I constructed.  Like my small routers I posted before I use a lot used biomedical research equipment.  All the T-slot aluminum and the white .5 inch plate aluminum came from an old Q-bot. The linear rails came from 3 Sagian 3 meter  robotic arm rails and the Z axis from a Sagian Mutiipet. The rack n pinion drive systems came from CNC router parts.  The electronics are a USB smooth stepper driving a PMDX-126 and the power supply is also from PMDX.com   The stepper drivers are Geckos.   I do have more work to do.  I want to add a tool touch plate and a rotary axis at the one end and dust collection system.
Regards,
Todd

Thanks Gerry,
I think that worked.
One more quick question for you.
I reinstalled windows 8 on a new SSD hard drive after my Win8 crash.  I do have access to the old hard drive files but I did not export my JointCam set up ???.  Did not think it would crash so soon.  Are the settings stored in a single file that I can pull off the old hard drive  or should I just set  joint cam up again?
Thanks again,
Todd
