Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Category: Installing LinuxCNC

i was able to bench test the image with the ethercat master installed from the repositories and it works. The only thing i found peculiar was that when jogging with the keyboard i could notice some random jitter in the drive. This did not happen with the amd64 cpu i was using before. I suspect this could just be an issue with the keyboard input on the pi though as that jitter is not present with commands from the MDI

See how you go with the position.

Regards shared himing switches, there is a pin joint.n.is_homing ot similar (check man motion).
If you and2 that with your physical limit switch and use the output to your homing input, the non homing joint will ignore the switch input.

Seems what I expected. 
What happens if you change bitlen to 32 and add ports 9 to 16?
You would need to get rid of the bitlen=8 line too.

USB isn't an option.

Parallel port maybe, but you would have to get Proxxon to confirm.

Hi,

Is LinuxCNC compatible with the Proxxon CU4 interface (via parallel port or otherwise)?

Lathe with C axis

Category: General LinuxCNC Questions

I decided to make a separate post for this. I have a Mazak Qt20 that is retrofitted with Linuxcnc. Currently I have a x and z axis.I want to mount a live spindle to the turret and use the spindle as the C axis. This spindle drive is a A06b-6044-h011 AC servo drive, I'm not sure what motor it uses, there is no tag on it. The motor drives a gearbox that drives the spindle and the spindle is connected to an encoder that is driven with a toothed belt. The encoder is a Tamagawa RFH1024-22-1m.
How should I connect the components ? Do I need to connect the encoder to the drive, as it currently is, or should I connect it directly to the Mesa card? Is there any other I/O pins that I should connect to or from the drive, other than enable, gnd, -V, 0V? How do I set this up in my INI and Hal configurations? 

I will attach a wiring diagram of the drive.

Switches shared on one input isn't the issue.

I'm trying to determine where the switches are in relation to the table movement so we can make sure that everything moves the correct direction during homing, and if need be move back to a position you want after homing is complete.

XZC live tool sherline lathe Post processor: Not reorienting after a step-down was created by ffffrf

XZC live tool sherline lathe Post processor: Not reorienting after a step-down

Category: Fusion 360

This is a long shot but I have been working on a live tool system for my sherline lathe. I am using a tryally QCTP and created a mount for a 33mm 60krpm spindle that I manually control. I modified a hass millturn lathe to output XZC moves only, and modified to use startcode that work with linuxcnc. However, I am noticing an interesting behavior that I am wondering if it is even fixable - it must be, no?The problem: Let';s say I have the endmill parallel to the Z axis, meaning it is in line with the axis of the part (the C axis), and I create a tool path that mills out a wobbly shape out of bar stock, but I need to do it in multiple stepdowns. The post and linuxcnc work as expected for the first stepdown, however, when moving to the next stepdown, it does not reorient itself back to C0, instead it simply continues to mill out the shape exactly where it left off. This means that the second stepped down wobbly shape is some random angle ROTATED from the top (first stepdown) portion. This obviously is not feasible for making parts...However, I am struggling to figure out a solution. One possibility is to try to introduce logic into the post processor that can try and detect when Z distance changes some value and somehow force a reset back to C0 to restart the second stepdown exactly where it needs to, but this seems complex especially if I am going to be varying stepdowns depending on what material I use, what endmill I use, etc.Has anyone thought something like this through? I will upload my Gcode for you all to see. The first stepdown is Z=-6, and the second stepdown starts at Z-10.  

Edit: I added the base Haas post processor that I am using. I almost wonder - shouldnt the post processor have some way of handling this itself? I cant imagine I am the only one trying to do such a cutting move?

Category: General LinuxCNC Questions

@spumco may be onto something? My limit switches are shared: both switches on one circuit. Maybe that's the problem?

@rodw -- My impression and hope was that if I homed to the upper right, I could somehow let the mill know that that point was 12,12 , and that therefore both axes would, yes, count in the negative direction, but not actually ever be negative. They would still go from 0 to 12, but it wouldn't be the 0,0 corner that homing was finding.
Does that make sense?

Are the program's extents available to the g-code?

Category: General LinuxCNC Questions

 Given that the length of the bit is variable, there is no single actual lower hardware limit. It depends on how far the bit protrudes from the collet. Given that, what's the use of the limit? When would it do me any good?

Adding an upper Z limit switch is usually pretty easy and makes it easy to use Linuxcnc as intended. eg Work in G54 offsets.
Normally, you would jog down so the tool touches the workpiece and set your g54 offset. 
Using work coordinates eg G54 was my biggest learning.
