Hurco Hawk upgrade, 5I25 to 5i25T

Category: PnCConf Wizard

As long as you have updated LinuxCNC, the main thing needed is to
change the 5I25T firmware to support the 7I77

sudo mesaflash --device 5I25T --write 5i25t_7i77x2d.bin --reload

5i25t_7i77x2d.bin is in the 5i25t.zip file (in /configs/hostmot2) available from Mesa's webstore

Hurco Hawk upgrade, 5I25 to 5i25T

Category: PnCConf Wizard

Hello all, been a long time since I set up anything with Linux CNC and i have forgotten most of it. My last experience was setting up a mesa card with a ethernet configuration with digital steppers. I have picked up a Hurco Hawk 5 with analog steppers and encoders. It had already been set up with  wheezy 2.7 linux cnc. It had a 5i25 with P3 to a 7i77 for the servo, encoders, and a pendant. P2 was connected to a mach3 BOB to control the FVD. the 5i25 is not communicating to the 7i77 due to rodent damage. I Have purchased a 5I25T to replace it.  I have backed up the linuxcnc folder to a thumb drive and the plan is to update to the newest version of linux CNC. What am i looking at to change for the 5I25T to work with it after i reinstall to the new version. I assume it is not just a streight swap of the cards.

Hello

Looking for help on where I go to change the 7i84U outputs to sink/source. the manual says I need to change the output parameters, is this done in hal?

Thanks

Stepper Driver Enable Pin

Category: Basic Configuration

I like to wire E-Stops to power, not enable pins, with as few steps as possible. Soft e-stop can control an enable/disable line, but "real" e-stops I want to pull power from motors. On my machine, it's set up so that the Mesa card is powered separately from the motors/spindle. The Mesa card directly controls the enable lines for the motors, but the power enable signal (to a relay controlling motor power) is also physically routed through the e-stop button such that pressing the button will remove power regardless of what the Mesa card wants. You can get e-stop buttons with multiple switches in them if you want/need multiple circuits being separately switched by one physical button.

I generally also like to wire things such that "power applied" is "enabled", so that a broken wire or loose connection will only disable the machine.

If you've got other safety hazards from just yanking power (eg, a Z axis that could fall), you may need to consider those.

Hi Victo4,

congrats for your project, that is pretty cool.

Your modded vertical Linuxcnc version is available to download?
I can't find it on your github...

Thanks and regards,
Adam

I assume you're referring to the hal file, "num_stepgens=4"

Yes, but you can also do this in pncconf so the GPIO pins become
available I/O options in the configuration utility.

Yes, load 4 stepgens so the unused pins revert to IO pins.

I have a Mesa 7i92 card with the firmware file 7i92_5ABOBx2D.bit loaded, using a Chinese 5-axis breakout board on connector P2. Pins 16 and 17 are currently taken up by stepgen. Is there any way to reassign them so I can use pin 17 to control a relay and pin 16 for mist coolant?

I haven't solved PIO yet (I went down a path that was interesting but did not work), but this PR allows stepping a little faster (50KHz), but also allows a lot more precision in step pulse generation and configuration of steplen, stepspace, dirhold, dirsetup, and dirdelay on the RP2040.

It also documents my future idea about PIO. I know how to make it work now and hope to get to it soon.

Thanks for the information HansU, I'll update my glade and fix the errors.

The GMOCCAPY documentation indicates that if no EMBED_LOCATION is defined, the the glade VCP will be floating. Is that no longer valid?

What specific errors are happening?

Are you getting failed posts, or g-code that doesn't work?

Keep in mind that the generic F360 post will require editing for machine-specific M-codes and other features.

I did have to modify the post to output G43 properly.

Qtvcp GUI and hal pins

Category: Qtvcp

After reading it a bit more closely, I think the current QtDragon documentation regarding Bridge_HAL is clear. It would only be helpful to add an example of the use of Oword subroutines to the [MDI_COMMAND_LIST] section, so it's understood that in addition to macros like G0 Z25;X0 Y0;Z0, subroutines can also be used.

Something I'd like to see, though I'm not sure if it's possible, is that AXIS has some functions that are executed through Key Bindings, which are very restricted in QtDragon. For example, in my case, I designed a control panel with a keyboard and external buttons. AXIS has the function to clear the plot, and if there's an error, a window appears on the screen indicating it. In AXIS, you can simulate closing this window with an external button, but in QtDragon, you can only close it using the mouse or the touchscreen. The same applies to deleting the plot; in QtDragon, you can only delete it by clicking the button.
