CSS/G96 for other than X-axis?

Category: Advanced Configuration

That worked like magic.

I removed all the jog-disconnect stuff from the M-codes and substituted
hal setp ini.v.max_velocity    0
hal setp ini.0.max_velocity    0

in the switched-mode M-code file, and the opposite in the normal-mode M-code.

Switchkins still works: parting slide is still connected to the X-axis controls, but the V-axis/Joint_0 simply doesn't move.
  • Axis GUI jog controls do nothing (!)
  • G-code V-axis moves do nothing
  • MDI does nothing
  • V-axis jogging does nothing (via MPG or continuous buttons)
  • No following errors or other issues noted
Best part is if I command a G0 Vnnn via MDI and then switch the axes back to normal, nothing 'jumps' like there's a blocked command waiting to be unblocked or re-enabled.

I'm probably missing some odd situation where this could bite me, but the fact is I'm only planning to use this switched mode briefly while the parting tool is in action (during a program) and then immediately restore the kinematics.

See any 'gotchas' with this?

SIEG SX3.5Z Drivers EtherCAT A6 Steppers

Category: Driver Boards

Hello,

i bought this Sieg Typ Mill SX 3.5 from Paulimot in Germany. I now need to buy Steppers and Drivers. 
This is the Mill:  sieg-sx3.5z i bought the mill with glas scales and i like to implement them in the driver if possible?

I am thinking of getting the following Driver and Steppers, if this makes sense:   400-w-ethercat-ac-servomotor-kit 
it would be nice if the experts can give me a feedback because iam quit new to this topic. 
thank you

CSS/G96 for other than X-axis?

Category: Advanced Configuration

I think I just found what may be a stupidly-easy solution:  set MAX_VELOCITY to zero.

I set AXIS_X & JOINT_0 max velocity to 0 in a test INI file and LCNC started up with no complaints.

Z-axis homed first, then X just sat there doing nothing - as expected.

Next test will be to edit the switchkins M-code and try it after everything is homed.

This may be of interest:
github.com/LinuxCNC/linuxcnc/compare/mas..._axes_in_interpreter

Adds a magic comment (disable,xyzabcuvw) to the interpreter. This allows the operator to disable any axis words (ie any of 'xyzabcuvw') in the interpreter. If the interpreter finds a disabled axis word in a line of gcode an error is raised.
Works for MDI and Gcode programs.

Interpreter: Add magic comment to disable certain axis words
(disable,<if none of 'xyzabcuvw'> )    ->  no restrictions apply [default]
(disable, z)   ->  if the interpreter finds a 'z' word an error is raised
(disable,zAb)  ->  if the interpreter finds a 'z', 'a', or 'b' word an error is raised

Notes:
 Only the first nine (9) characters (including spaces) after the comma (,) are considered.
 Upper- and/or lowercase letters can be used

Thanks a lot for trying that Andy. I'll compile your correction this evening. I will probably have to put the 2.8.2 SSD back in the machine, and I can also see if this works there without error.

If I fall back on somehing like 2.8.4 buster ISO, do I loose your latest macros layout?

I think it's a bit different. Because the original issue is about expanding the width but your window gets expanded in both dimensions.

This step 5 appears to be missing from the current documentation:

Step 3: Edit INI files

Thanks Andy, It compiles for me as well. I get the error when I have linuxnc load it.
 

That's working for me too:

     4  s32   OUT             0  turret.0.time

I have taken the liberty of changing the function name to "_" so that the addf line is "addf turret.0" not "addf turret.0.turret"

So the NML description in the LCNC manual isn't accurate? Or perhaps not exactly clear what happens?


Not sure but looking at motion/control.c gives me the impression that 'GET_JOINT_ACTIVE_FLAG(joint)' is used in motion mode FREE only:

github.com/LinuxCNC/linuxcnc/blob/c760c1...ontrol.c#L1217-L1219

but apparently not in modes TELEOP and COORD. So maybe it was only ever needed in FREE mode but who knows.

However I'm not sure this is the right place to implement what we want as we would still seems to cut things after the trajectory planner. Even if we are not updating the pos-cmd pin for that joint the internal position in the planner might still be updated and cause problems when reactivating the joint.

Many people look for used  beckhoff modules on eBay.

I used to do that a lot. Sometimes certain Beckhoff models I wanted were not available from ebay or seemingly anywhere else. A while back I contacted Beckhoff, asking them what distributor they suggest I buy from. They said they sell direct. 
File Attachment:


Now I mostly buy direct from Beckhoff. I discovered some new parts I had bought from ebay were more expensive on ebay than they were direct from Beckhoff.

The VFD takes 3 phase power at 360 to 480. I was wondering if I could just supply 220V power 3 phase to the VFD and have it power a 220V 3 phase spindle.

Probably not. I have yet to see a 480 volt vfd that will run without errors on 240 volts. When I have to run a 480V VFD on 240V, and replacing it is too hard, I use a big step-up transformer. Which tends to cost as much as a new VFD.

Announcement: Sink EDM orbiting

Category: General LinuxCNC Questions

Hello,
Sink EDM is used for makimg molds ( and more)
Orbiting  reduces cost and labor in making the tools for sink EDM.
Please look at 
github.com/tjtr33/sedm
It a 3D orbiting sink edm emulator.
Emulate means it will move motprs and draw on scree,
but does not cut because it lacks
a real programmable pulse generator
a real process controll gap voltage feedback.
Please look at the Github
and please work with me on it.

Look at my YouTube Channel
https://www.youtube.com/@tjosephpowderly1066
esp a quick start for sedm

Oops, my bad, I wrote that from memory and got RTAI and Preempt-RT confused, Rod. It is Preempt-RT I have installed. I'll edit that in the original post.
