Thank you for your quick responses!  Please tell me, am I correct in understanding that U22 refers to this chip? Could you also tell me where else in Europe it can be found, or any suitable equivalents? 

Hello!

I'm kind of a newbie with the LinuxCNC stuff. I enjoy working with this stuff. It's kinda fun...

But serious question now. I have a MESA board, 7i96s model and I want to make an automatic tool changer using the board I/O to control all the moving pieces and so. But I honestly have absolutely no clue ...

Can someone help me with anything to pull this thing off?

Thank you in advance!

Hi

Welche Versionen benutzt du gerade?
LCNC, Probe Basic und meine Routine

Hast du vielleicht in der Werkzeugtabelle noch die Pockets aktiv? Ich weiß nicht ob es relevant ist, ist jetzt erstmal nur eine Idee.

Muss gestehen, dass mir der Fehler neu ist.

Follow-on:

I'm working on a python program to check the levelness of my table.

I have several o<word> functions that are currently attached to buttons on the gmoccapy vcp, one to set zero_z, one to make the measurement and one to reset the spindle back to zero_z preparatory to the next measurement. All work as expected.

The python program is an attempt to automate the process measuring the four corners and the center of the table, then record the values into a spreadsheet. The hope is that overtime I can create run charts for each point to evaluate accuracy and precision.

Currently, the application moves to the Z height and sets zero_z calling the first .ngc function as expected. Next it moves the spindle to the first corner and calls the measurement.ngc. The spindle is lowered to the touch plate, but fails to move up and back down for the final measurement. It appears as though the function is failing to execute all of the commands before returning to the application complaining that the spindle failed to reach the touch plate.

I'm wondering if calling an o<word> function is limited to executing just one command when called by c.mdi("o<word>")?

Perhaps o<word> commands need to be processed with c.program_open. However, your previous response indicates that the code would be loaded but, not executed. 1) How do I get the file to execute after opening it, 2) Will loading a program preempt the execution of the running python program?

Any hints to get around this SNAFU?

Regards,

I am trying to call the Lcnc_Dialog widget from python code.

My code is as follows.

When the dialog pops up it lists all of the text in the msgdict variable and does not show the dialog as expected.

I know the issue is something simple I just can't seem to see the issue.

Thanks,

Can you reset the drive by disabling and immediately re-enabling the drive?
That is something that could be done in hal (at least for Z)

(assuming you have the drive enable connected)

Thanks a lot. Been using the same old things for too long. I'll have to look into this.
Thanks again

That is what I am trying to figure out. I searched online but found nothing.

I am borrowing an Altech din rail PSD-1505 from work for testing, (5 volt 12 watt 2.4 amp)
If that solves my problem I'll order the Meanwell.
Thanks for your help so far guys!

Can you change the drives disable behaviour?
If not, is there a way to reset the drive?

Yes,

the motor driver detects the fault and sends the signal to the the mesa. When driver detects the fault it also disables the motor (causing the z axis to fall). What I want is for the driver to stop the motor and hold position when it detects a fault not disable it.

... I simply want to be able to draw something in Inkscape, some closed loop and some curved lines that are not connected beginning to end, export it as a svg, import it into something and generate a g code.

Why would you export that as SVG when you CAN export it as gcode from Inkscape ????
Here is a quick video, just choose a mill instead of plasma:

Some tips:
-you can not export objects as gcode, only paths, there is a menu for converting things to path
-same goes for text, convert to path before exporting
-while Inkscape can do depths, it can do steps, probably not usable for depth maps

Awesome thank you!

I got a little more work done this morning, the PC now boots up when power is applied, the impulseformer is wired to 12v but I found the 5v is not hooked up to the correct pin, Chinese wiring diagram or I was wrong not sure yet, and all the raceway is snapped back into place so you can't see the rats nest of wiring. Should hopefully have the machine scales reading something when I find the correct wire for 5v. All of the other pins rung out correct so it's just the one color wire. I ordered a touchscreen interface so I should be starting the build for the control panel when that arrives. I need to decide if I want the jog wheel on the interface or on a pendant or both. Regardless I have a 7i73 for that stuff. I am considering implementing a 4x20 LCD display into the pendant control but don't know if that would really add any value as my touch screen will be fairly large and easy to read or I hope from a distance.

“This header has a pin-out that matches a standard parallel port.”

This is true and it electrically matches  standard parallel port in terms of drive
and overvoltage capability.

PC parallel ports are also not suggested for direct connection to motor drives
where a single wiring mistake can permanently damage a motherboard.

It is possible to use the outputs of P2 directly (as you can with a PC parallel port)
but  care must be taken to avoid even an brief contact to a voltage  outside the safe range.

7i97t_5abobd is designed to interface to the common Sainsmart 5 Axis BOB:

As tommylight mentioned, eusurplus is a Mesa distributor and they currently have the 7I97T in stock.

Also as I mentioned, your damaged 7I97T is very likely repairable.
