Is there an easy way to swap axes?

Category: General LinuxCNC Questions

Mark - you're running a LCNC version pre-joint/axis?

EDIT:

I'm not familiar with pre-joint/axis configs, but one thing I noticed in your HAL files is that it looks like there's a mismatch between the INI and HAL axis numbers.

Vertical:
INI - Y is axis_1
INI - Z is axis_2
HAL - Y is axis_1
HAL - Z is axis_2

Horizontal
INI - Z is axis_1
INI - Y is axis_2
HAL - Z is axis_2
HAL - Y is axis_1

Make sense?

Do you have halui.pause or resume pin connected somewhere?
from the docs:

If using the Spindle lift option, HALUI can not be used to pause/resume the program. There is a pin, QtDragon.external-pause available to pause/resume from an external source. You must also enable external offsets. In the setting tab check use external offsets

also for qtdragon_hd line 41 should be un commented

The files real name is .axisrc (note the leading dot which makes it a hidden file) and it goes in the users home directory. If it does not exist then create it.
Both commands will work from ~/.axisrc and will be applied to every LinuxCNC config.

I understand, but I didn't identify any file called axisrc, just create it? Does it need to be in a specific folder? Will the root_windows command you mentioned be inside this file too?

Yes, you are missing the:

addf pid.u.do-pid-calcs servo-thread

so the "U" PID pins are there but they are  not functioning

z axis inverted in NC file

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
