Mesa 7i96S MPG encoder on P1

Category: Driver Boards

Hello PCW,

A few days ago i flashed my 7i96s with the 7i96sd_inmp1v2.bin file. Flashing was without error.
Since then, the X-axis-homing does not work anymore.
Homing of y-axis and z-axis works fine, as expected.
I would be glad to get your help to solve this issue
Is there a way to get the 7i96s in the state before flashing ?

Tanks a lot

7i96S Referenzfahrt X-Achse funktioniert nach mesaflash nicht mehr

Category: General LinuxCNC Questions

Hallo Zusammen,
Ich bin neu im Forum und wende mich an euch, da ich den Fehler beim Referenzieren der X-Achse nicht finde.
Meine LinuxCNC miz 7i96S hat wunderbar funktioniert, bis ich die Karte mit dem file 7i96sd_inmp1v2.bin geflasht habe.
Ich habe nur den flash gemacht, an der pncconf usw nichts geändert. 

Die Y-&Z-Achse referenzieren nach wie vor wie erwartet, die X-Achse fährt in die falsche Richtung los, d.h. vom Referenzschalter weg,
wenn ich den Schalter von Hand betätige fährt X einfach weiter, der Positionswert ändert sich nicht auf 0, zählt einfach weiter.

Bei 2 Punkten bitte ich um eure Hilfe:
- Welche Ursache kann dieses Verhalten auslösen ?
- Wie schaffe ich es die 7i96s in den vorigen Zustand zu flashen ?

Über jeden Input freue ich mich, den bin-, hal- und ini-file habe ich abgeängt.

1 encoder, nur ein.
7i83 hat kein encoder eingange, 7i85 oder 7i85S soll 4 encoder eingange habben.
-
Ich wurde die 7i95T mit 7i83 nemen, fuhr mehr IO noch ein 7i84 nemen, oder 7i73 fuhr die konzole ...

it's possible...i measured 24V on the output pins.....these lines look different then when the machine was last operational but i had ChatGPT produce these...they don't seem right to me but i don't know enough...my board is a 7i76EU so i was thinking of replacing 7i76 with 7i76EU......if i comment these lines out the z axis brake doesn't release...

Is it just about homing sequences? Or do you need to keep a fixed ratio for the axis?

So, with the help of the AI assistant I found out that it is a HID device. I entered the command: sudo cat /dev/hidraw4
then when I press the keys, characters appear in the terminal.

Hello, are you still having problems with your homing? I use the El7 homecomp for my A6. If you're still interested, I can upload my config.

Rotary Encoder to adjust Jog-Speed?

Category: Advanced Configuration

halui.joint.jog-speed (float in) - pin for setting jog speed for plus/minus jogging.

i connect a potentiometer to it and bring it in the hal together...

i see that halui.joint.jog-speed changed when i look to the halpin.
but the jog speed doesnt change when i jog.

i jog with the pc keyboard!

is it possible that this is only working when you jog with like a joystick???
or a button on a pendant for plus and minus???

i use a handwheel... my target is to move from increment to increment with a selected speed.. like:

i select joint 0 and increment 0.1 with the rotary switches on my pendant, then i rotste the handwheel.. the jog speed is the same wich is selected with the jog speed bar in AXIS. now i want to adjust this Speed with another encoder or pot.

but i understand it works only with buttons for + - axis movement together.
and this is what i understand that it works like a joystick.

or i am complete wrong?

Hallo @tommylight

Das ist ein schönes Retrofit "ich ziehe meinen hut"

Du verwendest da die 7i92 TM  ich war mir eben nicht sicher da die TH und TM doch unterschiedliche beschreibungen haben. 
Die 7i76 gibts auch nur mehr als 7i76U deshalb tu ich mir so schwer bei dem vielen was ich gelesen habe weils eben die alten karten nicht mehr gibt.
Aber 7i92TH mit IDC26>DB25 und 7i76U und 7i83 an Serial EXP
oder 7i92TM direkt an 7i76U (spart Kabel) und die 7i83 an Serial EXP
Oder hast du eine bessere alternative als die 7i83 mit smart serial also momentan werden mindestens 3 Spindel Servos gebraucht 
 
Hab ich das nun so richtig aufgedröselt

5 step Dir
6 -10 - +10V
7 Encoder
1 poti
32 ein 
16 ausgänge
Mit deinem Okay hab ich entlich eine steuerung die Servos sind schon am weg
danke dir und einen schönen tag

XHC-WHB04B-6 not increasing MPG counts was created by beefy

XHC-WHB04B-6 not increasing MPG counts

Category: HAL

Used xhc-whb04b-6 -ue in a terminal window, and can see all buttons working.

However, in the line:
pndnt wheel total counts {counts=0 activeCounter=0 isLeadActive=0}
all the values remain at zero.
Thing is with every click of the MPG there are other digits in the terminal window that are doing something so it appears the MPG clicks are being noticed by the driver.
Watching these digits (which are either 0 or 1 or -1) the 0 digit appears to be incrementing with MPG clicks but immediately returning to 0
The digit which is either +1 or -1 seems to change when I rotate the MPG forward and revere respectively.
So overall it appears the xhc-whb04b-6 driver is actually recognising the MPG pulses but is not incrementing the total pulse count.

I can also use xhc-whb04b-6 Ha and then start Halshow.
Once again, all button presses show up in Halshow but counts stays at zero when using the MPG.

My big question is: does the driver need some sort of feedback pins setting from Halui, in order to increment the pin:
whb.axis._<N>_.jog-counts

You would not normally see much of a change in STEP
pin outputs as the STEP pulses are short and do not change
the average voltage ( what a voltmeter reads ) very much.

You should see a change in the voltage on the DIR
pins when jogging in different directions.
 
It this possibly an issue with the motor drive enables?

ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

Category: Driver Boards

Hello,
Recently I bought a 5A-75E v8.2 board, but I can't get the JTAG programming to work.
I have used the configuration file for v6.0 to build the firmware.

openFPGALoader detects the FPGA correctly, but when I attempt to flash it, it throws the following error.
linuxcnc@linuxcnc:~$ sudo /opt/oss-cad-suite/bin/openFPGALoader --cable dirtyJtag --detect

I have checked my connections multiple times, they are correct. What is the issue here? Is it maybe because of dirtyJtag?

let me correct what i seen on the Step pins. I seen a very small drop from 5.08V to 5.06. Seems like something was holding it back.

Thanks.  I've made those corrections. I've made some progress today.  When i remove my physical estop button i can now hear the Z-axis brake release but still no motor movement on any axis. I took the step of putting a volt meter across the Dir and Step pins on the Mesa board.  I initially see 5V on all pins. Then i ran the MDI command 
G91 G0 X0.1.  I see values changing in Halmeter for pid.x.command, pid.x.output, stepgen.01.velocity-cmd and a voltage drop on the Dir Pins.  But no voltage drop on the Step pins.  This is the case for all axis.I feel like I'm close to getting this to work again.  My wiring has not been changed since it was last fully operational on all 3 servos.  I can't get them to move in the DMM software either.I'm attaching my Hal and Ini files.  For some reason it's not letting me load the Text files.  Any help is appreciated.Thanks Therman Simmons Fort Mill, SC
