Is mini still available?

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!

Weird G54 orientation

Category: General LinuxCNC Questions

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!

How to control brake before moving ?

Category: HAL

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.

also - (I have just started using it and only have the 1 material in which is 1/4 inch. ) Made a sample program using conversational to get the jest of the gcode.

See below for the gcode I used as reference.
It uses tool 0 as far as I can tell - and as far as feed rate this seems correct - when I change tool 0's feed rate - it changes the programs feed rate. OK..

But - I have the arc voltage set to 120. When the program runs - the arc voltage is a constant 115. I actually added 5v on the override so it actually shows 120 when cutting.

am I doing something wrong?

Am I missing it? Is there a way to display the current velocity of the machine while cutting?

Thanks!

BTW - Just setup Plasmac using pncconf - It was painless and QTPlasmac is a really nice gui. No problems.. (mesa style board with thc10)

Great work!

Inverting jogging sense of X Axis on a VistaCNC P1A-S pendant

Category: HAL

Since this is for a lathe, there are only 2 joints in the HAL parameters. LinuxCNC requires that the joints are numbered from 0 consecutively, that is, I can only have joints 0 and 1. The association between joint 1 and the z axis is done in the HAL files. With that association, GCode works properly.

As I mentioned before, the pendant was jogging the X axis as I wanted in Step, Velocity and Continuous mode before I moved to the mesa card. I was using exactly the same vc-p1as.hal file as the one I'm trying to use now. Something very subtle changed and that's what I'm trying to figure out.

I tried debugging with halmeter and see what signals were triggered when I used the pendant, but that didn't help much. I'm still learning about the HAL.

Thanks once again for looking into this issue.

The gcode (M62,M63,M66) method with digital I/O will work for any motion but you need to change the gcode.

If you need more than just G0 moves then you would likely need to make something up in HAL.

I can only control the brake with G0 moves.
here is the way;

[EMCMOT]
EMCMOT = motmod unlock_joints_mask=0x08
...

[AXIS_A]
...
LOCKING_INDEXER_JOINT = 3

[JOINT_3]
....
LOCKING_INDEXER = 1

I have to control the brake for G0,G1,G2,G3 and manuel movements. Because that axis' motor has mechanical brake.
In any type of movement, brake is have to be deactivated and after the movement it has to be activated again.

Do you have any opinion else ? What else I have to try?
