Where would I find this?

Has anyone used this to make a GUI similar to mini (deprecated several years back) or something similarly simple.

Do you have any other older PC?
You can install everything on another PC then move the drive to the machine PC and it just works 98% of the time.
What is the PC make/model?
Try pressing F12 for Dell (F8 for Asus and F11 for some others) with the USB inserted and right after powering on, see if it shows a bootable device list.
Try a different USB, i refuse to believe any PC after roughly 2002 will not boot from USB, even earlier PC's mostly boot from USB without issues.
Is the HDD a PATA or SATA?
PATA = 40 or 80 wire flat cable
SATA = small connector with thin wire, usually black or red color.

Disconnect the power form all but one drive and do some tests, then connect another one and test...
I am pretty sure it is an interference issue with bad wiring and/or bad grounding, so u7pload some pictures of the wiring here so we can have a look.

Anyone have any more suggestions on what I can check/try?

I am now on 2.7.14 Wheezy, Dell optiplex 9020, Netmos9900, and latency under 6k. The stepper will jog and then quit working shortly after, regardless if there is "pausing" or not. The PCIe parport shows "disabled" in lspci -v, and even if I enable it via the terminal, the stepper still doesn't work unless I reboot.

Any ideas at all are appreciated.

There is nothing on the Hard Drive except Ubuntu

Why do you need to control the brake like this?

Stepper motors have full torque at 0rpm. If the stepper is powered you should not need the brake. Brake should be turned off when the CNC is powered on, then brake should reactivate when CNC is powered down.

Or is this a brake for 4th axis machining?

Brakes integrated into steppers or servos are not designed to be used for machining, they are jus to hold axis position when the motor is off. Usually to stop Z axis falling under gravity.

You could try this:

I liked it also, after 2.7 it went to joints/axis(something like that) and mini was not maintained after that.

well, maybe you dont need to use the preassigned index, you will find out i guess

[code]# Spindle QEI encoder

setp encoder.0.position-scale 800.000000
net encoder-count <= remora.PV.0 => encoder.0.raw_count
net encoder-phaseZ <= remora.input.6 => encoder.0.phase-Z
# setp encoder.0.index-enable true

i dont think you are connecting your spindle pins correctly thought. its waiting for the index enable probably
compare to this one

Awesome, yeah my hal was a mess. I ended up just grabbing that example and tweaking what I need to to have things make sense for my machine and I'm happy to say, everything is working now. Exactly how it should, and we have threads! Thanks again!

I have 3 new Mesa cards for sale. I bought those as a spare for a project but never needed them. All three are brand new, never used.

Mesa 7i77:  $180.00 USD     Come with a free set of 2 new din rail adapter   
Mesa 7i92   $  85.00 USD     Come with a free EPP-M parallel cable  (6 feet)  
Mesa 7i73   $  40.00 US

Will ship USA lower 48 only
Shipping for 1 item: $10.00
Shipping for 2-3 items: $15.00

I will list on e-Bay if no interest here.

Can you explain the "tool offsets...X and Y which is a bit unusual", please? The way I HAD been working was to (1) home my machine, (2) jog to the origin of my workpiece, (3) click the "touch off" button for x and y, (4) move my z to the the surface of my part and "touch off" z. (I also made a script with uses the tool setter for Z, but I'm leaving that out for this experiment.)
I don't think Fusion is setting G54.
@aciera thanks for the reply. I appreciate your comments!

The usual reason for brakes on non-indexing axes is to avoid unwanted motion when a driver is disabled. So, my first question would be as to why the motors on your machine need to have the brake applied while the motor drive is enabled.

lol - never mind.. I think I found it.. I will test tonight..

If Use Auto Volts is checked then the actual cut voltage is sampled at the end of the THC Delay time and this is used as the target voltage to adjust the height of the torch.

If Use Auto Volts is not checked then the voltage displayed as Cut Volts in the MATERIAL section of the PARAMETERS Tab is used as the target voltage to adjust the height of the torch.

Ventoy seems to be detected on BIOS-only systems where the Ubuntu ISO would not work on its own.

Try out Ventoy.

Try out Rufus, with different settings.

I installed Ubuntu on an old, BIOS-only laptop (c. 2011 Dell XPS l702X); Ubuntu only boots if the system partition of Windows 7 is there on the disk.

I strongly recommend leaving about 100GB unallocated during install so you can always install Windows 7 to that 100GB just so it will boot at all.

Note: If Windows is installed using the whole disk, it seems to put everything in a single partition; if you choose a custom install (using only part of the disk), it seems to install the OS to one partition and the boot stuff to another, small partition. You can delete the OS partition, but the boot partition might be necessary.

(Don't ask me why Ubuntu needs the Windows BOOT partition to work on my laptop, it just does.)
