If its still of interest, the limit switches are normally closed, and go over a relay to the controls.

[SOLVED] New wifi card causes second parallel port to stop working was created by sajurcaju

[SOLVED] New wifi card causes second parallel port to stop working

Category: General LinuxCNC Questions

Setup:
LinuxCNC 2.9.0 using Axis, configured with Stepconf
Dell Precision Workstation T3500, 8g ram
Radeon HD 5700
Two identical Sunix PCIe parallel port cards
Mint Debian Edition 6
#1 SMP PREEMPT_RT Debian 6.1.128-1 (2025-02-07)
6.1.0-31-rt-amd64
Why do I have two parallel port cards? Some time ago, I damaged the MB parallel port.
This setup works great.

When I add a wifi card (TP-Link PCIe Wifi card AC600), the second parallel port card address changes (per dmesg). I updated the hal with Stepconf for the new address. Now in Axis, the Machine Power button is grayed out, like the estop circuit is open. Estop-in is on the second parallel port card, so I'm interpreting this as the wifi card is somehow blocking the second parallel port card.
I shutdown, removed the wifi card, updated the second parallel port card address, and it all works fine again.

Put the wifi card back in and ran ptest
forum.linuxcnc.org/18-computer/4743-parallel-port-tester   (thanks BigJohnT)
Both parallel port cards work with ptest, with the wifi card installed.

Advice will be greatly appreciated.
Steve

I was considering getting these drivers. Did you manage to get them to work, or should they be avoided?

sorry Snow.

1. no tried again with a different file.
2. yes, cut, then frame. its a time lapse.

I did some testing tonight and all is good until i zero off the laser pointer.
The code i'm using for this is
G92 x0 y0/ G0 x-2 y 104/G92 x0 y0

Is this code wrong?

Also, everything is fine, until I zero on the laser pointer.

Combined MESA board order for Australia.

Category: Driver Boards

Hi all 
I need to order a 7i73 and shipping is $90 USD to get it to Qld Australia. This may be the unavoidable cost but I can't justify it for a $49usd board.
I'm happy to wait a couple of months if necessary and combine freight with others ordering from Mesa.
If your considering ordering and would like to combine our orders and split freight costs PM me. 
Cheers Brad.

Hi Stenly, I bought these Signal converter . They cost a lot more than I wanted to spend but at the time I thought I was going to get it going quicker. Approx $130USD each. The Aikron ones might be worth the gamble. Or if you are more tech savvy than I am currently then the ones jochen has linked would be a option. Here is their reply to my email for the ones I bought.

"Your calculations are very helpful.  The HEIDENHAIN LS 486C has a 20µm resolution glass which, as you correctly calculated, will produce a 10Khz signal at 12m/min.  I have attached a data sheet showing the federate limits of each interpolation version for your reference.  You can choose any interpolation option from 0.5x to 5x.  The 5x interpolation model (SA 1872) will provide you with a 1µm TTL output signal. "

In all likelihood they just have the chip jochen has linked

Got it to build. The install script, as far as I can tell it doesn't bring in libclothoid3d and libscurve
When I did that manually (path here forum.linuxcnc.org/38-general-linuxcnc-q...orm?start=170#323932) and copied that to the empty directories the code builds.

hal functions

Category: General LinuxCNC Questions

Thank you! That did the trick!
I'm currently getting familiar with the HAL Scope.

After displaying the encoder position and the stepgen feedback position, I noticed that the stepgen was counting positive while moving in the positive direction.
I corrected this by adding a minus sign in front of the STEP_SCALE.

However, this caused the motor to spin in the positive direction during homing.
I fixed that by removing the negative signs from the homing and latching velocities.
There probably is a nice way to fix that, isn't there?

Edit: I've added working .hal and .ini files for future Reference. (only X has encoder feedback)

Which kernel version is best for real time?

Category: General LinuxCNC Questions

The thing is a newer kernel will only have better performance if there has been significant changes in the area that are being used in your application. Changes to filesystems you don't use, drivers you don't or in architectures you don't use don't expect any improvements.
To be really sure you have to read change logs and stuff like that to be sure. Newer may very well be the same as what was supplied with the Linuxcnc ISO.
Oh and don't run any other network services that you use for your motion controller, in your case you should have a dedicated NIC for Remora and another for everything else.
I still don't know why people insist on using 3rd party remote desktop clients when X is actually was designed from networking from the beginning and there are plenty of available clients and servers in the distro repos that have been time tested.
Running a CNC machine remotely is a another kettle of fish. If you need to do remote admin use SSH and learn to get comfortable with the command line.

Yes, the field I/O section of a 7I76 is a Sserial device (basically a 7I84 but local)

Hi PCW
Yes, I did set it to zero :)
I did not know that Smart Serial Ports were needed to make anything io cards work.
I thought Smart Serial IO was to link via serial connectivity to some kind of remote daughter board.
I shall search on the forum to find out more about it.
Many thanks for your help :)
Much appreciated.

Looks like you set the number of sserial ports to 0, disabling the 7I76 field I/O
