Firmware Request for 7i92 – Plasma CNC Build

Category: Driver Boards

For a 7I92:

7i92_5ABOBx2D.bit

for a 7I92T:

7i92t_5abobx2d.bin

Would be closest If you are using the common "Mach 5 Axis" Sainsmart parallel port BOB

Note that the inputs of the common 5 Axis breakouts are not really suitable for encoder use
as they are quite slow and require 12 V signals.

Thank you, they were messed up. We ended up making a new config and the homing now works. We had skipped a section in pnnconfig that enabled homing. It is unclear in the documentation.

7i76E Spindle configuration

Category: PnCConf Wizard

thank you for your words, I am very sorry about Mr. PCW, I respect him and I appreciate him.

I want you to be able to put yourself in my shoes as a LinuxCNC user. I have an application (pcconf) that I have used without problems in previous versions, which is not working today. I create a thread in this forum seeking help because my ability is not enough to solve the problem, I receive help and instructions to resolve it, I try to do what is requested as best as I can, I send videos, images, explain, answer more than once what I am being asked, it is not a bad attitude, it is my lack of ability that cannot satisfy those who are helping me and it is respectable that they eventually reach their limit, but there was no bad intention!!.

I need to control a VFD with the ACM-AVI signals + 10VCC (YASKAWA GA500) The Pncconf wizard should have given me the TB4 configuration when I selected 7i76e, but it didn't. that is the problem !!

There is no tension on pins (1-2) (1-3) of the TB4

I was able to manually program turning on-off-enabling, but when I wanted to program the hal pwm component and assign it to spindle out, it did not allow me.

So, as a user, I wonder why the PncConf Wizard application did not provide me with the TB4 configuration. And that is my problem to solve.
I know that the problem is overwhelming me, I just need to solve it because I have been an intensive user of linuxcnc since 2008, I use it every day of my life since then, I have learned a lot but not everything and I continue learning.

thank you for your time, I greatly appreciate it

I would suggest setting up a configuration for 4 joints X Y Y Z. You should not be pointing multiple step generators at the same frequency command or command feedback.

Take a look at this 5 joint config where there are two joints assigned to the Z axis. You can do the same for your dual Y axes.

Firmware Request for 7i92 – Plasma CNC Build

Category: Driver Boards

Hello everyone,This is my first post here on the LinuxCNC forum, and also my very first CNC build — so please forgive any mistakes or lack of experience on my part. I'm doing my best to learn as I go.I'm building a plasma CNC machine and using a Mesa 7i92 card. For my setup, I’ll be connecting two 5-axis breakout boards — one on P1 and one on P2. I’m looking for a suitable firmware that would allow me to:

Use 4 or 5 encoder inputs (for THCAD and potentially other uses)
Have at least 10 inputs and 5 outputs for general machine control

I’ve checked the Mesa site and the firmware list, but I’m not sure which bitfile would suit this configuration best. If anyone has a firmware file that fits these needs — or could point me in the right direction — I would be very grateful.Thank you so much in advance for your help and patience. I really appreciate the knowledge and support shared in this community.Best regards,

Gusgus

Hello once again!

I haven't really been active but we got to testing once again and now I have encountered another issue I don't understand.

So now we get movement and stable connection to the octopus, we got an spi cable with shielding and that worked wonders, thank you tommylight for the suggestion and thanks Scotta for all the help.

The issue we are encountering now is that we have x y1 y2 and z, but we only get movement from x and y1, y2 and z are completely unresponsive, we have eliminated the drivers and their wiring since if we connect the y2 and z terminals to the x and y1 outputs on the octopus we get movement from them.

We have them wired to the octopus' Motor 4, 5, 6, and 7 ports, which are decleared in the following config:

All the pins are generated in the correct order it seem's, we are gonna test next the output signal strength, maybe the drivers don't have enough power on high state to start moving, even if everything is connected to the same ground.

When you make a config the only changes are made in the linuxcnc/configs directory in your home folder.
No changes are made to any system files, none at all. So it doesn't matter how bad a config is made it does not affect anything outside of the above mentioned directory.
PCW is a very patient member of the forum and the guy that runs Mesa Electronics. This is the first time I have show any frustration with a forum member. Ever.
When you have an issue, with anything in this world, diagnosis follows a process. Whilst it may not make sense to you, it does to those offering advice. To go off do something that is unnecessary and you have been advised not is deeply disrespectful and can quite possibly throw a spanner in the works and bring you back to where you started. Eventually people may come to the conclusion that trying to help is not worth their.
The best course of action would be to go back and follow PCE's advice to the letter, do not skip a step.
For a second time does your spindle controller require an analogue voltage, or does it require a PWM signal. Actually it may be an idea to qualify what controller you are using and any documents pertaining to the spindle controller.

I've thought about it for a long time and think I've found a pretty good solution.easy, cheap, rocksolid, no mcu, no IC

signal -> nf-transformer -> rectifier -> transistor (+resistor and capacitor) -> Relais/SSR

Finally I got it working. I shortened the spi cables, reduced spi frequency, tried erasing and flashing remora via stm32cube, nothing worked. But after some time it automagically started working. I don't know how it worked?

Changing the OS/LinuxCNC version is a complete waste of time.

This is most likely a hardware or hal file setup issue.

I explained how to debug this issue, but was ignored, I'm out.
