[Emc-users] linuxcnc-features-master

Greetings all; I have, I believe, after going over in "wiring up" procedure in the README.md file, done everything it seems to call for. But linuxcnc falls over while initializing. Heres a paste from the cli: gene@coyote:~/linuxcnc/configs/sim.axis$ linuxcnc -l LINUXCNC - 2.7.3 Machine

Re: [Emc-users] Rewiring the BP

When nothing else works, it's wise to go back to the beginning. After so many suggestions, recommendations, and disagreements we have not solved this problem since last year. While grounding could be a major issue, it's not necessarily so in this case. As long as there is star wired ground.

John, Yikes! You mentioned to me to check my shielding on the limit switch wiring. It seems that will help, but something else is going. You had mentioned/requested a picture, so I finally got around to putting them up here: http://imgur.com/a/d1jqu Those pics were during the retro-fit, so the

Re: [Emc-users] Rewiring the BP

I have 3 DC power supplies in the drive side, a 5vdc, a 24vdc, and a 170vdc. The 5vdc power supply on the 0v side reads 37.6 ohms with the 0v and 5v sides connected to the 7i77 5v plug. The 7i77 is the only thing it powers up. When I unplug the 7i77 0v reads open so there is a path through

[Emc-users] Resetting rotary movement count

I created a program to cut a circle from thick steel plate, moving the X axis to the radius of the plate, and using the rotary table to rotate the blank. It slowly cut its way through until it came to the Max_Limit for the rotary axis () then it stopped with an error message saying the next

Re: [Emc-users] Lost fractions of a step

As promised, here is the follow up: 1. After extensive testing of the A axis running a non-integer-step-producing angle several thousand iterations it appears, just as John K said, that the "leftovers' are dealt with within the planer in an intelligent way and there are no measurable residual

Re: [Emc-users] Resetting rotary movement count

I have a small lathe that I set up to use a servo drive on the spindle, essentially making the spindle a rotary axis. The servo was large enough to provide the torque needed to make the cuts and it made coordinated spindle moves wonderfully. (think thread cutting, cam grinding, milling cutter

No, Andy, it was a rather coarse thread up to very close to the flange of a large (british...) cutting head shaft. A shop man gave it to me because they had failed in several attempts to make a mill shaft that would fit the head. Apparently, I was the first to find out that it had two start

Andy, I have run my Graziano lathe with the frequency converter as low as 5 Hz (for a delicate job of threading) - I wouldn't have liked being the one to stop or slow down the lathe by mechanical load or attempting to brake the chuck even at 8 rev./min! Only thing is, at length I have to watch

Re: [Emc-users] Resetting rotary movement count

I had problems in this area, I think it is not a feature but a bug that an rotary axis cannot be set to 0 or be infinite in its rotations, the wrapped rotary docs as an option just seemed wrong for this when I last read them a few years ago. Winding back is a very slow operation and should not be

What it boils down to is not the VFD but something in the DC or low voltage circuits. I don't have a modbus problem but rather a sserial problem. Thanks On 1/4/2016 3:00 PM, Rafael wrote: >When nothing else works, it's wise to go back to the beginning. After > so many suggestions,

Ok, I am 99.9% of the way there…. I created a file called /usr/share/X11/xorg.conf.d/10-monitor.conf (after reading the Debian Wheezy has it’s configs in that directory rather then /etc/X11). In 10-monitor.conf I have: - Section "Monitor" Identifier "VGA1"
