Xilinx Zynq 7010 fpga crypto windfall boards

Category: Driver Boards

wow, you made so much progress compared to me! i only managed to boot it and connect to it using ethernet to check that its working. it came with crypto software installed which has web server and dhcp configured so i managed to connect to it via browser using ip address.  
now i am waiting for proper jtag that recognized by vivado to start playing with it. 
i too thought about potentially running linuxcnc on zynq but i suspect those cores are just too slow at 600mhz.
I actually like vivado. wouldn't it be nice to have cnc modules (step gens, counters, pwm etc) set as ip blocks in vivado so it can be just visual drug and drop to create configuration you need.

Retrofit - LinuxCNC + EtherCAT

Category: EtherCAT

There is no existing VFD. The spindle motor is a large, old 3-phase induction motor, and it’s currently started using a classic star/delta starter.

The actual spindle speed is controlled by changing gears in the mechanical gearbox. There’s no electronic control involved right now.

I plan to keep the gearbox, but replace the starter with a modern VFD. That way, I can at least get rough electronic speed control, without trying to replace the entire spindle drive system on such an old machine.

How many uncoordinated axis can linuxcnc drive?

Category: General LinuxCNC Questions

I tried setting up extra joints but am struggling to run them in gcode with custom M codes. Does anyone know the best way to do this? Just need to home and move into position.

5 axis milling machine with 7i96s

Category: Driver Boards

Hi Everyone, 

I am new here and new to CNC, Linux and Mesa boards, so pls excuse the novice questions.

This is my setup
I have a 5-axis milling machine, which uses 2 stepper motors for the z axis, so in total there are 6 stepper motors. I have also bought a servo motor ECMA-C21020RS from Delta to power my spindle. I have a Mesa 7i96s card

Now for my question
Have I bought the wrong Mesa card for my requirement? From my understanding, the 7i96s can only control 5 motors so my 6 steppers and servo exceed the capacity. If so, what would be the best solution? To buy another card and scrap the 7i96 or is there an option to buy an add-on card to work with the 7i96s?

Thank you in advance for your help

Mesaflash not working on 7i96s but it pings

Category: General LinuxCNC Questions

Hi Everyone,

First of all, thank you in advance for your help. I should mention I am new to Linux, new to CNC, and new to Mesa cards. I have been following the tutorial for getting started with the Mesa 7i96s by talla83 en, but I have been stuck for the last couple of days trying to get the Mesa card found using the Mesaflash command but it always says No 7i96s found. I have tried following tutorials for changing the local IP address, thinking there is a conflict as well as changing the jumper on the card to change the IP address but neither have worked. I wanted to put up my settings here hoping one of you will notice a glaring mistake I have made and could point it out. Thanks once again

LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

I've been playing with the WLED plugin, got a string of 5 led's working for various things, that is really cool.

I thought I'd try add a blink function to one of them. I see that only the WLED_Expansion allows me to assign an LED from another plugin, but when I try I get the compile error

Procedural assignment to a non register "LED_BLUE" is not permitted.

Any idea what I'm doing wrong

pulse width was already 100,000 ns so that wasn’t the issue.

Was that "base-period" ?
Pulse width is 5000 by default, base period is 100000 by default, if not set otherwise, but base period is only present when you select using a parallel port, and this might have been the issue with stepgen numbering etc...

Configuring LinuxCNC 2.9.4 Mesa 7i95t Newbie.

Category: Milling Machines

I would use pncconf  (the new one in the link) or MesaCT
and avoid AI as it's really just a time sink here.

I have never seen a missing module in 2.9.4

( There is no motion.so in LinuxCNC so don't take bad advice from AI )

The only option would be to buy a cnc lathe, which is not a budget option.

Every other option is going to require you to do some wiring.

Even something such as this,  github.com/clough42/electronic-leadscrew , will require you to do some wiring. And this is only a solution to screw cutting and doesn't have any cnc capabilities, tho it doesn't connect to a computer.

Once a again another Electronic Lead Screw,  www.rocketronics.de/en/els/ geometry dash lite  no connection to a PC,no cnc capabilities but does other some extra features. Is still a user install, so there is wiring involved, but no connection to a PC. not really a budget solution.

First mistake was using a buck conveter, 2nd I would seem to be not checking the operation of the buck converter prior to connecting everything up. 3rd mistake would have been to triple checking everything.Simple solution would have been to power the breakout board from a known and working 5v supply or whatever voltage the BoB required.

 Thank you very much for your help.

New 7i95t Open Loop Stepper Driver Issues

Category: Driver Boards

There is no specific driver for the 7I95T, its supported by LinuxCNCs hm2_eth driver.

Normally you don't need to do anything with the on card firmware unless you have some
specific different I/O requirements. ( Like you want one step/dir output to be PWM/DIR or
you have parallel daughtercard  )

Not sure what explains the initial lack of functioning, possible an issue with the 7I76
config file conversion.

OK there's only one yellow LED on in the center of the board.
so that means analog power issues.

Most likely problems are:

U33 (74ACT04) bad ( can be damaged by a 5V surge to 6.5 or 7V )

Q3,Q4 (FDN337,NTR2101) bad ( can be damaged if U33 fails )

A bad OP-AMP = U3,U8,U14,U20,U28,U35 (MC33179) for channels 5,4,3,2,1,0
Note that if an OP-AMP failed, it's most likely the ones you had
connected.

I would try replacing U33 first and then rechecking.
