Today I was able to get the spindle to rotate, but I've encountered two new problems. While the DI4 wire is connected to pin 16 of the bobbin to reverse the spindle's rotation, it always remains reversed, regardless of whether pin 16 is activated or deactivated. I checked with the HAL meter, and pin 16 is working correctly. I also measured with a multimeter, and when it's activated, it reads 0V, and when it's deactivated, it reads 5V, but the spindle always rotates in the same direction. Interestingly, when I disconnect the reverse wire from pin 16, it rotates in the correct direction, and if I reconnect it, it reverses direction, but nothing happens from the interface using pin 16.

The other problem is that the RPMs don't match, for example, an M3 S1000. I've tried to correct this unsuccessfully from both the driver and the HAL. I have a 1.58:1 pulley ratio (45mm motor pulley, 71mm spindle). My knowledge of Linux CNC is limited, and I'm not sure where to go from here.

I'm not sure if I've explained myself clearly. Sorry for my English.

XHC WHB04B development?

Category: General LinuxCNC Questions

Hi,

I'm interested.
I also have the problem that the connection disconnects after a while. For me, however, it's enough to close LCNC, disconnect the dongle, and reconnect it.
I'm interested in the feed setting of the rotary knob button.
This doesn't work; only the increments can be set. I was only able to solve this with a workaround.

XHC WHB04B development?

Category: General LinuxCNC Questions

Hi,

Is anybody interested in some development for the XHC WHB04B pendant? Both from a user perspective, but also with the development itself.

I bought a WHB04B-6 to use with my mill, thinking it should work okay. But of course there are issues. After a while, it disconnects and I have to restart LinuxCNC to get it back working.

I have already went quite deep with this, and have some and can generate more material:
 - USB packet captures with Wireshark (form both LinuxCNC and Mach3)
 - USB signal capture with logic analyser
 - WHB04B transmitter firmware
 - RF signal capture

One thing I noticed with the xhc-whb04b-6 component in LinuxCNC is that is has some blocking wait states. These can delay the USB polling of the WHB04B so much that it causes the device to reset. I fixed that (for myself), but still there are issues...

There are several possibilities:
 - improve the xhc-whb04b-6 component
 - create a new driver/component for the pendant, realtime if seen necessary
 - create a new firmware for the WHB04B transmitter, possibly also for the pendant itself

Any comments or thoughts from the community?

I guess many have the opinion that both wireless and USB pendants are a no go. Personally I don't see an issue at least for "garage application", provided its properly implemented. The main thing would be to have a watchdog monitoring the communication, which can (e)stop the machine if necessary.

hal.h in install image different then hal.h in github?

You need to checkout the correct branch. The release versions are defined by a tag dso that are locked in. You can see this in git on the branch drop down if you select the tag tab. This will let you see the exact source for the version you have.

to get the source of 2.9.8 on your pc its  :git checkout v2.9.8

Are the settings only possible through their software?
There are no SDOs for setting such things? Like Rtelligent has?

Yes there is. I will load the sdo docs on my NAS later, Seems like the app gives you access to all the SDOs and you can save them to a text file for later reimport so if you had a few of these drives it would be easy. The sdo docs sometimes have a better description.  You could make these settings from the command line using the ethercat app without putting in your XML. They show as bring Read/Write so hopefully they can be accessed when homing.eg reduce motor power when homing

found it! I hope. More in a minute!
@hakan Yes, I experimented until I got a max velocity of 2000 mm/min which was roughly 400 rpm! So no fb when homing is not fixed. That I want to sort out. I'll stay on this config until I work this drive out

@NWE In the windows config program Plug it into the USB on the drive. It is safe to leave plugged into Linuxcnc (check thw com port in Device manager) before ruunning the software.

There was a setting  #25 PA_055 "The percentage unit of current of the lock machine" was set to 40%. Changed it back to 100%
I had previously set the current #21 PA_051 to 2 amps (2000 mA) so it did not have much) So now I will play with max velocities now to confirm its what I think it is.

It moved!
I only tried the second motor yet with my finger on the shaft
halcmd: setp lcec.0.0.1-target-position 0
halcmd: setp lcec.0.0.1-target-position 20
halcmd: setp lcec.0.0.1-target-position 0
halcmd: setp lcec.0.0.1-target-position 20
halcmd: setp lcec.0.0.1-target-position 0
halcmd: setp lcec.0.0.1-target-position 20

each time I felt a twitch

Now I better grab some sleep

This is looking better. Now I need to tape flag those motor shafts so I can see if they moved like my terminal claimed. Wait, keyboard's wireless, it CAN reach from my desk to my workbench...

rodw, probably a coincidence but 400 rpm = 6,67 rps. 5mm per rev gives 33.33 mm/s which is
awfully close to your MAX_VELOCITY in the ini file.
Happy you got it to work.
I find one learn a lot by messing around and trying to solve issues, real or not.
Here I got to practise setting the controlword manually

Still the issue with position feedback during homing, right?

My order showed up today! 

Great! 2 idiots now! So just to be sure you are using my latest XML without the torque pins and dominic's cia402.comp component?
That works. My stuff is going back to the drawing board

NWE, with controlword at 15 set op-mode to 8 (csp) and try to move again.
Don't move a lot at once, it can overwhelm the drive. Linuxcnc moves just a tiny distance every servo cycle.
Should see it on position feedback.
