Hi Endian. 

The scurve planner uses :
libclothoid3d and libscurve
libclothoid3 depends on libceres.

the scurve planner is tpmod.so.
loaded by linuxcnc.

Do you only want to use libscurve to generate motion for servo motor?



 

I've been trying to install the Probe Basic lathe all afternoon without success.
I've followed all the steps just like I did with the mill.
Is there a specific configuration for installing the Probe Basic lathe?

Yeah, that's not a sine wave (more like a rectified sine wave)
This may be something wrong with how you are measuring this
differentially (scope setup). Measuring single ended as Hansu suggested
would eliminate this possibility.

Is this connected to the converter? According to Heidenhains docs
the 1V P-P signals need a 120 Ohm (across 1V+ and 1V-) termination


The fuzzyness is likely just noise.

I suspect a problem with the encoder if you don't get ~1V sine waves when properly terminated

Marking up where the parts will be placed.
 

Sorry, I did not want to upset anybody. It is my fault. Sorry.

Thanks for the quick reply — that already helped a lot!

I switched the scope channel to AC coupling and used a drill with an Allen bit to move the spindle. Now I can finally see a sine wave (kind of).

However, two things are still puzzling me:

1. The sine wave appears very thick on the screen. My guess is it’s some kind of electrical noise, but I’m not entirely sure.
2. The amplitude is only around 50 mV, which is way lower than the expected 1 Vpp.  
   

Any idea what could be causing the “thick” waveform, and why the amplitude is so low?

what and which should be declared for basic workbench setup
After install, you can run it. See link how to setup and run.

 
 

Hello,


what does exactly meas "Additionally, the following libraries are required:" ... If I want to install the S-curve generator ... I will need both them install too?Additionally, the following libraries are required:

• S-curve
• Clothoid3D

Haha, post lost, so I re-invent it.
I think for basic experiments a 10 USD parallel port PCIe card and a bottom level parallel port break out board wiill get you up and running for 20USD. (excluding wasted work and life time).IO
The MESA card solved my encoder issues within short time and I (#not sponsored) th think it was a good decision, even if someone informed me that I could have bougtht a "yet again undocumented" device for 5% of the MESA  fee,


 

No Mesa 7i92 for you!
Get the Mesa 7i96S, it is much easier to wire in and less sensitive to mishaps.
For now, old PC parallel port, some cheap drives, get the machine moving.
Or get the Mesa 7i96S and some cheap drives and make the machine move.

the macros will be very specific to probe basic. the setup of it is done inside the ui to try an make it as simple as possible for those using a stationary rack. the graphic requires some IO to show the tools in the rack also. it would require alteration for a moving rack such as yours. but thank you for the offer!

Hello



Here I have a macro, I don't know if it is useful for the work you are talking about

Is this correct?

 

get it sorted?

waiting on knoxmachining to finish the macros as he has a machine to test on. the framework in probe basic is complete if you want to write your own macros. he has had some work keeping him pinned down unfortunately. hopefully he will get some time freed up soon.

um... good question...

you dont actually load the stlinks with remora firmware. stlinks probably need the daplink firmware or something, and then the stlink passes the firmware from the computer to the NVEM
