Category: General LinuxCNC Questions

No file.
And the ini is not set properly for a mill, the Z=0 must be the top point on the machine and everything below must be negative value, or in your case it should be Z min -5.
Despite that, it can work as is if you use the touch off.
And the above "must" is what is normally used, not written in stone.

I've also had no luck with an out of the box STLinkV2. But ColdTurkey has got it to work

pyocd.io/docs/debug_probes.html

"Recent STLink firmware versions will only allow access to STM32 targets. If you are using a target from a silicon vendor other than ST Micro, please use a different debug probe."

If you have a couple of probes you can always flash one with the following firmware.

No motor control using 7i96A and DM542T drivers

Category: Installing LinuxCNC

Common issues are:

Too short step length (set step length to double the drives minimum)

Insufficient OPTO LED drive (use single ended wiring on OPTO inputs)

Also on later DM542Ts you must select 5V signal levels (via S2)

No motor control using 7i96A and DM542T drivers

Category: Installing LinuxCNC

I have just finished my build of a CNC table. I am using a 7i96A controller driving three axes. I cannot get any of the motor to step.
I built a configuration using PnConf , I have a tandem Y axis. I can get nothing to move regardless of which axis I try.
When I power on the system all the motor lock, as I would expect.
I am driving the DM542T differentially and I have nothing connected to the enable inputs of any of the motor driver, which should mean that they are enabled.
I put a voltage meter across the direction input of the Y axis and jogged it forward and revere. I see the input flipping between -5.95 and +4.95 so I think the direction is working but I seem not the be getting stepper pulses.
Can someone suggest the next course of action. I am a bit lost and disappointed that I spend a good deal of time and money on this project.
Anyway, I am looking for suggestions

thanks

jogging the axis works fine. The machine has a homing switch on the Z axis at the top of its motion range. the .nc file is attached for reference.

Alright a few other related forum posts (forum.linuxcnc.org/gmoccapy/34296-xhc-hc04-lost-connection, forum.linuxcnc.org/38-general-linuxcnc-q...-hb04-pendant-issues) convinced me to upgrade LinuxCNC, which appears to have solved the issue.

I upgraded from 2.8 to 2.9.3.

I'm having problems flashing the controller. I have tried two different STlink v2, but I only get error messages. Does anyone have any idea what the error could be?

Category: General LinuxCNC Questions

Comment out any line with "7i76" in the hal file

(Make copy of the hal file first so you wont need to uncomment them when things are working)


also did you:

sudo mesaflash --device 7c81 --spi --addr /dev/spidev0.0 --readhmid

To verify that you have the correct firmware loaded?

Maybe I am having a senior moment, but how do you test the step/dir with a 7c81 when you can’t get LinuxCNC to run?

hi
i am cambridgeshire , close to peterbrough . how far are you from there?
M1 is close just how north are you?

im sure folks can help on here etc alot of info etc on the forum now. what is the problem you are having? is there one part you are having issues with? is it linuxcnc side or wiring it up ?


what is the machine in question any photos you can share etc, how much work is already done
what is the system, servos or steppers?
can you share some info here?

i have done many linuxcnc retros, all big iron mind you. laths & mills, and a few old denford mills & Lathes for people over the years... all with mesa cards , using old drives hard ware & new etc.
