Okey, are you referring to make custom firmware/component for FPGA for UART + quadrature encoder logic or referring to hal component?

I had a pretty hard time finding a pc with a parallel port. I don’t use a mesa card

The new pc is a dell optiplex 980 That is a very compact unit. The old HDD doesn’t seem to fit in the housing.

I use pcloud for gcode synchronization and I just couldn’t open the site on 2.8. So I decided to install te latest version of LinuxCNC

Your reasoning is somewhat flawed.

First of all, you don't need a PC with a parallel port, you can just install a PCIe parallel port card in some PC.

The HDD does not technically need to fit into the housing; you can just plug the HDD into power and SATA while the HDD still physically outside the computer.

You can always dual-boot LinuxCNC and some other OS for your GCode Syncing.

For example, you could install Ubuntu Desktop 24.04 LTS or GhostBSD or something to your new drive for non-CNC stuff (like pcloud) and plug in the old drive with the original, working LinuxCNC install.

You can download Gcode files to your CNC drive from the other OS.

A virtual machine, the scp command, or simply copying gcode files downloaded on another computer from a USB key could also be a solution

You should be able to fix the graphics driver issue without reinstalling, though reinstalling is often a good solution.

However, if you want your machine to work as it did before, using your old install on your old HDD is probably the go-to method.

You would need the Xilinx tool chain (Webpack 14.7)  for a 7I92, 7I92H, 7I92M

Please don't post the same questions in different threads.

CT identifies it as Mesa 7I92 and suggests corresponding files for upload.
I uploaded several files to it as a test. It works fine.
Test assembled on the table CNC program moves the motor + outputs and inputs work.

Hi,

I was wondering if any could give some insight on this one.  I tried to use the M6 subroutine that orangecat made.  I was able to get the probe working, change the ini and hal files accordingly.  I got to the point were the tool would probe, but my tool table won't populate with that number.  When I debug the 5063 in mdi I get ###### not an actual number, however the 5063 variable will show up in the var file in the config folder as a function of the 38.2 probing routine as an actual number.  I tried to debug other variables like 5181 which is the x position for the G30.1 command and although the var table in the config folder would populate with a number, when I debug the 5181 in mdi I still get #####.  I'm assuming the debug should yield the same number in the var file and not this symbol #####?  Which might be one of the reasons my tooltable is not populating?  I'm happy to provide any files, youtube videos, or anything else needed to help solve this problem.  I've learned a lot in the last month trying to solve this problem, any advice is much appreciated. 

Thank you in advance.  

Are you really using 2.8.4 rather than 2.9.4?

This problem was fixed in 2.9.5. Do you have a good reason not to update?

(rather than 2.9.5 you should probably use 2.9.7. See:
forum.linuxcnc.org/21-axis/57364-axis-co...-9-6?start=10#336658 )

Yep, consider that when static, a 5A stepmotor may only drop 3 VDC so ~15W.
So with a 48V driver, only about 400 mA at 48V is needed to get 5A at the motor.

 

Think of it as a buck converter...

First, it's still not clear whether you have a 7I92 or 7I92T(x)

The support software zip file that has all the sources and project files
needed to build firmware files is downloadable from Mesa's webstore
(in the specification tab for the appropriate card)

The Leadshine manual I read (prior) says this:

Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the Driver. However,
unregulated power supplies are preferred due to their ability to withstand current surge. If regulated
power supplies (such as most switching supplies.) are indeed used, it is important to have large
current output rating to avoid problems like current clamp, for example using 4A supply for 3A
motor-Driver operation. On the other hand, if unregulated supply is used, one may use a power
supply of lower current rating than that of motor (typically 50%～70% of motor current). The reason
is that the Driver draws current from the power supply capacitor of the unregulated supply only
during the ON duration of the PWM cycle, but not during the OFF duration. Therefore, the average
current withdrawn from power supply is considerably less than motor current. For example, two 3A
motors can be well supplied by one power supply of 4A rating.

Perhaps Leadshine is a bit too conservative, I guess you can get away with even less power supply capacity.

First, make sure what 7i92 you have, there is 7i92/7i92M/etc, then there is 7i92T/7i92TM/etc, meaning with T and without T, they have the same functionality, but use different FPGA so flashing the wrong firmware is not good.
They always have a sticker on the back with the model written.

Young??? I am 55!
And the dog got banned from the shop for a while as i got tired of monitoring her so she does not pee at everything!

The cutting machines and the many, many other things are great! Who is this young gentleman with the pretty white hair, and where is the dog? Thanks and have a good time!

Hi I found a 7I92_7I76x1dpl.bit which would be good.According to its description, it also has 2 PWM outputs onP2 7-8 I/O.Unfortunately, the description and reality are not the same.It doesn't have a PWM output.
The card has 2 IDC 26 connectors.
1 connector standard LPT assignment 1-25. 26 pins +5V
2 connectors 1-17 pin input 18-25 GND 26 pin +5V

Where can I get the 7I92_xxx.vhd files?
